MK7 VW GOLF RUST ISSUES + HOW TO PROTECT YOURS

[@jamest5149]

Just remember Bilt Hamber do a hard wax for high impact areas

[@volkswizard]

Nice one, didn't know but now I do!

[@kashv2500]

What's the hard wax called?

[@paulgriffin647]

Dynax ub drys hard , it’s a brown wax, dynax uc is same wax but clear, dynax s50 is for cavity’s it’s a softer wax but migrates into voids/ welds/ seams etc, excellent products 👍

Yep Dynax S50 Use a brush also to work it in. Also comes with along tube for cavities etc

[@matts3327]

When I do that sort of job I put a plastic bag over the brake disc - just saves any wax contaminating the disc / pads.

[@Rayfaedundee]

I did my 2015 Mk7 Golf GTD which I’ve owned from brand new which has 16,375 genuine miles at the moment with another rust protection spray called Lanoguard. It’s 2024 now and It’s still like brand new underneath yet .. I did the front inner wings and lower edge at the door pillar of the wings, the rear sills inner and outer areas, and all the suspension and chassis floor.

[@79blustone]

Nice attempt- but seriously, don't do what this guy has done. First of all- who wants to do this sort of thing mid winter?? Mistake no.1..... 2, One can is simply not enough, if you've committed yourself to doing this task you'll need a minimum of three cans for a vehicle this size, you'll want to take the engine undertray off and any other coverings to get right underneath to cover the entire chassis, do it right, do it once. Mistake no.3, prepare the vehicle properly, don'tdo this without cleaning off old dirt and road salt. Remove the inner flich liners AND jet wash clean with some strong alkaline shampoo like Carpro reset shampoo and a brush, rinse (behind the liners!! Not clean them when mounted). Let it dry completely. Mistake no.4, cover up your brakes friction surfaces, yes it will burn off but initially it could cause brake failure if you messed up. Bilt Hamber Dynax UC is safe of plastic and rubber parts, try to avoid rubber bushes as it could make them soft but I doubt it'll be a concern. Work your spray patern from to top to bottom in continuous spray patterns for good coverage. Work into tight areas with a small paint brush or old detailing brush- remember to tape over the metal part of the paint brush so that it won't scratch any paintwork. Bilt Hamber has a cavity wax with a very long spray tube for getting inside the chassis and gaps. Pick a sunny summers day in preparation, clean the car and dont trap and spray over old dirt....🙄

[@ian3792]

Hes about 2 months too late , you should of done a video , the golf 8 new is already rusting complete shit show they are

[@79blustone]

@ian3792 Couldn't agree more. I used to be a technician for VAG, they are built to a price, in Germany, they are just another car like Renault and Peugeot. Clever 1990s marketing stuck with the middle classes and became a brand associated with them. They build in when parts will fail. The German mindset is all about making money. A reliable car doesn't make money. Germans are greedy.

[@dirkdingle7926]

So ya telling me my mk7.5gti has them stupid foam inserts in the front wheel arch,tomorrow they will jacked up and they shall be removed,I noticed the other week on mine between the doors on the sill a rust spot was upset loads the quality of VAG is crap but like you say they don’t want you keeping/having your car for a long time these days

[@4ndy65]

Im amazed that vw are still putting these bloody sponges in after what happened in the past I found out on a golf forum that my Mk5 gti was prone to wing rot and removed them before any damage was caused Did still remove the wings and attack them with hammerite sill paint😂

[@dirkdingle7926]

@@4ndy65 got new wings for my 5 gti years ago I paints them them black hammerite inside and ran a bead of sealant on the inner lip I’ve also drenched them in bilt hamber uc there holding up great but now have spots of rust on the outside of them,my 7.5 has loads of rust spots on the rear archers too I’ve bought a can of matched paint to spray the arch and then again cover with bilt hamber but the weather is always crap

[@Newb_S]

Good video. I’m currently doing the rear sub frame and arches on my edition 30. Overall it’s in fine fettle with a bit of corrosion on the spare wheel well underside and subframe. That’ll get buzzed off and treated with Bilt Hamber Hydrate 80. Everything will then get coated with ACF50 and Bilt Hamber Dynax UC like you did on the Porsche. To combat the arch to bumper rubbing i’ve removed the rear lights and bumper and plan to use some clear 3m helecopter tape between the 2 panels. Finally the inner sills will be hit with Bilt Hamber S50 cavity wax. Hopefully this keeps corrosion at bay for a few more years.

[@singleplayer75]

Thanks for posting this, it's very useful and informative BUT - if we want this done properly the car needs to be raised on a lift, with the wheels and well protectors off. The splash shield/skid-plate needs to be removed also.This way you can apply the compound of choice to BOTH SIDES of the affected chassis area. If you spray only one side you've basically done nothing to really prevent salt and moisture-caused corosion. Not everyone has the means to DIY so it has to be done by a proffesional, once a year, maybe more or once in a few years, depending on where you are. I own a 2013 Golf 7, no rust at all, but I consider myself just being lucky. All I do is pressure-wash it thoroughly after each drive in winter, that's all. But that alone is obviously not enough for everyone. Thanks again for your effort!

This is why I don't buy VW products any more. I was put off when I saw the state of my then 2 yr old MKV GTi and it's creeping rust problems. Great to hear you're still sourcing cars you always traded fairly and were honest to a fault even if the deal didn't work out.

Friend of mine had a Mk6 GTI with some nasty corrosion on places you wouldn't expect. Took some time and money to sort that out. My 15 yo French car is absolutely rustfree, times have changed... (although it still has the French quirky issues, but that is another story).

[@davideyres955]

VWs quality went down over the years. I had a MK2 polo classic and it had zero rust on it after nearly 20 year before the engine caught fire (couldn’t find anyone to steam clean it prior and it eventually went up due to an oil leak). My mk3 golf vr6 is suffering rust in many places. They clearly have known issues they don’t fix.

I had a 56 plate seat Leon and pushed for the corrosion warranty knowing that vw were repairing front arches on mk5 golf’s. Took a lot of battling and actually had an Arnold Clark that wanted to help! Result was two new arches and respray.

[@roch145]

I’ve got a 2013 Golf with rust at the top of the wheel arch in both front fenders. Rust in both sills where the foam inserts meet the sill. Rust on the perimeter of the opening for the high mounted brake light. And rust along the opening for the passenger side door handle. I live in upstate New York where lots of road salt is used in n the winter and had to replace the rear springs due to corrosion. The car comes with a 12 year rust warranty and VW will be repairing all of these corrosion problems under warranty. The dealer’s body shop is taking many months to schedule the repair. So far I’ve waited 5 months and they tell me I need to wait a few more weeks. After watching this video I will have some additional questions as to how they intend to repair the rust. What are the corrosion warranties for VW’s in Europe?

[@veefource]

Interesting to see the corrosion prone areas. Using a paintbrush works well for spreading it out and into crevices (worth putting insulating tape over the metal part of the brush body if it has that when new though to prevent it damaging any paintwork). Also might be worth putting some carrier bags over your discs to prevent contamination of the braking surfaces 👍

[@stco2426]

Wondered that about the disks, too. Agree with your advice and the general material here. Will take a look inside the arches in the coming weeks.

[@funglam7395]

Went to look at a MK7 14 plate and although ten years old I was surprised to find a little rust at the front of the rear drivers wheel arch. Only a small bit mind and the dealer says they’ll sort it but it’s well and truly put me off getting one

[@jwester7009]

Those rust issues are exactly the same as what I'm seeing on my mk5. I had to replace both front wings and through away those water sponges. The car has a complete Dinitrol under coating treatment including full cavity treatments. Maybe that is why it hasn't rusted more than it has

[@chrisp4899]

My 2014 leon hatch that I used to own started rusting on the leading edge of the rear arch within stone chip paint area I used kerust to slow it down

[@kaurvali]

VAG products tend to be buckets of rust. I found this video randomly after dealing with rust fixes on my Leon Cupra. I have a 2015 Leon ST FR, 2020 Leon ST Cupra and a 2023 Formentor in close family. The 2015 Leon is a lost cause, rust is everywhere. Main locations are the door sill in the rear fender, bumper mounting location on the rear fender and the front fender mounting screws. It is in a really bad shape and I gave up on it, needs a full respray. On the 2020 Leon Cupra, the front fender has not been an issue as I clean & wax it twice a year when doing a wheel swap. Usually with half a year it is full of crap - leaves etc. Same with the bumper mount, but mostly because I added PPF between the bumper and the quarter panel. Also covered the rear fenders with PPF except for the sill part. That has been a big mistake - the rear part of the sill has rusted really badly, gone 5cm under the rock protection. Also looks like the fenders like to rust on the inside, between the fender liner and fender itself. The rear part of the fender (so the body) also tends to get rock chips in the rear. So based on that on the 2023 Formentor, days after buying it I took off all of the plastic fender extensions, all fender liners. All of the fender edges got PPF and the line between the rear bumper and the body was PPF’d. Front fender lower bolts were cleaned and covered with a lot of wax, noise deadening was removed and replaced with a more waterproof one and made sure it did not touch any of the lower sill . Inside the fender, as much as possible, I covered the exposed paint with PPF. And after that everything was covered with wax. So basically, if you want it to remain rust free, every single year it needs some wax and cleaning. I tend to use Liqui Moly cable grease (seilfett) as it is very thick.

[@colintx800]

It's CRAZY that my Corsa C which is 18 years old, which I've had from new has NO rust at all. I'm shocked that a VW can rust this quickly!! My car has only needed new batteries, CV boots, brakes and oil changes . I have no engine issues at all. I have saved sh!t loads of cash and it's still going strong. I was looking at buying a VW but now I'm not so sure 😲😲

Golfs have rusted due to that piece being there for 25 years. Amazing. I've had 4 cars with wings replaced under warranty due to it and they still refit it!

[@davidclarke7656]

You had the wrong nozzle on the can - there's one that provides more of a mist-like application. I apply a thin complete and even coat, perhaps a second after the first dried.

[@marksaunby9594]

I’ve just bought a 2018 golf. I’m aware of these issues as my other car was a mrk 5 golf but Vw replaced my wings but not sure if they’ll do it on this car if the wings started to rust . I’ve removed only one of the foam blocks like you said but going to see if it makes much difference to the noise. I was thinking now that I’ve seen the blocks could we not cut the block down were it fits into the wing then the water wouldn’t collect and if it dosnt stay in place maybee silicone the foam in place

[@WeAreTheUnhappyMajority]

It's not just VW, it's pretty much throughout the VAG range. I use ACF 50, everytime I change the oil, I'll ensure all exposed metal gets treated. I run onto ramps and make a detailed application on the substructure, suspension and even the whole exhaust system. I'm pretty lucky my car is 1 year old so I didn't have any rust to start with.

I noticed the fabric rear wheel arch liners on our Golf R 7.5 are leaving 7mm wide X 5cm long gap over to the metal bodywork in one place. That will let water/mud etc in behind the fabric.It is a poor design. I peered into the arches of other VW models, including a GTI, Polo etc, and those had no such gaps. Why the GTI has a better design beats me. I am going to cover/fill the gaps with Sika-seal super 200 and see how it goes. Sika-seal super 200 is a hybrid of acrylic and silicone rubber that cures to a MUCH tougher substance than silicone rubber alone and does not tear or split Water cleanup before cured. Not for external use is stated but I have found no breakdown after 3 years in Australian direct sunlight..

My mk3 cupra 2018 has the same rust as the mk7 gti. The NS sideskirt at the front corner is completely rusted onto the sideskirt by 2-3cm across. Its a joke

[@kentowers2802]

To prevent corrosion on these I would recommend removing the front and rear bumper corners where it clips to the wing and clean them out periodically Dirt and polish etc builds up in the gap and rubs the paint off under the arches

[@chinnyvision]

I'm skeptical as well as there was a fad for undercoating classic cars in the 80's and it turned out to have been a terrible idea unless you were fully confident all issues had been treated beforehand. It just locked the rust in and as soon as the protective layer got punctured or stuff got in from the other side you had a whole heap of problems.

Rust? Really? Shame on VW. My Golf 4 GTi TDi had none back in the days. I removed the foam blocks behind the front fenders, cleaned all wheel arches in the summer and used ML / Tectyl on vulnerable locations. The car drove long after I had sold it. I think it was scraped eventually due to high mileage.

[@kashv2500]

Good video 👍. The quality of VAG group has gone down alot, my old mk4 golf had half the amount of rust my wifes current mk3 Scirocco has. Why more people are importing VAG cars now from Japan, less rust on them due to how they treat their roads and climate is alot better

[@stco2426]

I might hope that VAG imported to Japan would still have the same build quality as those sold here. JDM cars don't (or didn't) tend to have the same rust-proofing applied as the same vehicles they made for export. That at least is the common perception.

I bought it in Feb and it was quiet, got worse as weather warmed up. Late summer I could move callipers by hand and they would clonk. Today at zero degrees it's perfectly silent and callipers don't clonk so must be something to do with expansion. I would get the pads off and adjust the clips but pointless now as it's still quiet so one for spring and summer, pretty confident it's those because callipers make a noise by hand that's similar and they've been touched before. Also it's left and right side making the (clanking) noise when driving and both callipers make the clanking noise by hand so fingers crossed :)

[@volkswizard]

It doesn’t appear sticky no but temperature will have a part

[@robc5955]

I’m a bit surprised at the front wheel arches, having just changed the alternator on my mk3 Octavia, based on the golf 7, and having therefore to spend more time removing plastic wheel arches and under trays than doing the alternator, there is body coloured paint some of which is stone chip where there seems to be just primer on the golf. Is this a special primer Skoda don’t get ?

No it’s just VW’s beanccountants are ‘better’ than Skodas’

I would have it done by a professional instead of spraying some around myself. It costs a bit but then you can be sure that it is good and you have a warranty. Moreover, Dinitrol is still the best anti-rust agent. But if you really don't want rust, don't buy a Volkswagen!

[@royfontaine5526]

Dinitrol is shit. I’ve had it crack, both underbody and cavity. Would end up causing more trouble than it solves. They weren’t interested when I contacted them.

[@jan4004]

@@royfontaine5526 No, of course they weren’t interested. Anyone who uses Dinitrol in any way knows that it remains supple and self-healing for years and has very good penetrating properties. If your stuff is cracking, it certainly wasn't Dinitrol you used.

@@jan4004 it was genuine Dinitrol, purchased from a reputable (perhaps the best known) retailer. And it was indeed shite. Would never use it again.

@@royfontaine5526 It's about the product. The best retailer sells exactly the same product as the worst retailer, that doesn't mean anything. Furthermore, it's your car and your rust and that's fine as far as I'm concerned, you don't have to convince me.

Hi Andrew, another great video. I wish I had watched this and used spray on wax instead of using a thick layer of tarmac to cover all my suspension components and undertray . Still at least the little white stones they used to compliment the tarmac, look lovely 😊

[@obsessedcloset2638]

My second CSS had 2k miles and was used in one winter and the rust on th suspension components was unreal. To the point where I did a complete rear underside refurb on it. Have a look on detailingworld. VW components are all cheap steel with a light coating of black satin paint. Dreadful. In the end I sold my car. The first one I had was protected underneath with dynorol. It worked well but collected every bit of crap. When these cars were new or even a new Mk8 GtI / R I would 100% be coating the underside. BH products are brilliant.

[@volkswizard]

Great feedback thanks - the problem with undersides is once you've looked it's often too late

[@viper42x]

Interesting. I have a 2016 Golf 7 GTD Variant that just hit 300.000km (~187k miles) a few days ago and my Golf has absolutely no rust whatsoever. I checked, but none of those spots show any sign of corrosion or previous corrosion. Just the edge of the lower part of the hatch has some rust that you can only see when you look for it, but that's due to the previous owner having had a low garage ceiling and his hatch hitting the ceiling, rubbing the paint off in the process. I'm just gonna sand the edge down a little, apply some primer and go over it using a paint pen so it looks good again and won't rust again.

[@CC-uh8gl]

Did VW stop applying cosmoline on their cars to protect from rust?

[@jasonleefosterb16]

From owning a 90s civic for 20 years, rust was on ongoing battle. I used Rust Bullet paint esp useful for high impact areas. The stuff sets like concrete, extremely hard wearing. It was developed for the US military, used on wing tips of US fighter jets, warships and other hardware, so its been used in extremely harsh conditions. One tip, don't get it on your skin, it takes weeks to come off.

[@tomdaniels2446]

Hi Andrew, very helpful video, thank you. Did you have to do any work in advance of applying the wax, such as removing surface corrosion with a wire brush? Or can the Dynax can be applied without this being necessary?

[@richweston6202]

And the " worst " golf - mk4 , most still have less corrosion than mk7s VAG quality went down hill after MK4

@@twinring3846 Hi after being used to BMW DCT I was unimpressed with the inconsistent sometimes during cornering waiting for the shift and also a gearbox that overrides the paddle shift may be safe but why bother with having paddles if it's going to be an automatic.

Hi Andrew, thank you gor your honesty regarding rust issues on Mk7.5 Golf's. Drspite our 2014 GTD having an awful reliability record, at leasr it's not going rusty. I had been thinking about replacing it with a Mk7.5 GTi or R, however, have there only been a few isolated cases of rust on these later cars, or is the build quality that poor that they'll start rust quicker than Mk3 Golf's? Mosr of us knock Ford and other mid market brands for their inferior build quality, but my Mother in Law's Mk2 Focus has been far more reliable (and rust resistant) than the Mk5 and Mk7 Golf's we've owned.

[@Janton17]

Great video, Id also recommend EM121 Epoxy rust proofing. A friend uses it on his JDM STI scoobs and it seems to hold up to UK weather well, plus is a bit thicker. You can request custom colours to for anyone wishing to keep the "OEM" look (although its not OEM).

Nice one Gary, make sure you give it a good wash before applying. I didn't do this but liners off then pressure wash might be best way on a car that's done a few miles as the muck hidden behind them can be significant (don't know mileage of yours). Especially that area between rear panel and rear bumper.
