The most common issue... 2.5 TDI Touareg 🔧

The 2.5 TDI can be one of the most reliable engines going...once the issues are fixed 🤦‍♂️
This Touareg came in with a very familiar popping sound coming from the engine, something we instantly recognise as failed cams! And wait until you see the difference between a brand new cam and the one that inside this 2.5 TDI Engine 🫣

Wrong oil gets put in the R5 2.5. Pre 2007 requires a 0W30 A5/B5 (VW506.01)Most people just chuck in a 5W30 C3 (504/507)which has less extreme pressure additives due to the nature of being a low saps product. This in turn causes extreme wear on the cam lobes. Just my 5pence worth

[@NonoOfPyro]

My 2.5 Touareg is close to 300.000km (around 190.000 Miles). I think the Engine (besides having a bit of a lack of power) is quite a longrunner. Just change the oil after 15.000km, use fully synthetic 0w-30 and delete the EGR. Just drove about 1.500km this Weekend and managed to get around 8l/100km 💪🏻

[@BeatLounge]

Finally you are touching the 2.5 thank youuuuu

[@DarksideDevelopments]

We've done a bit on them. Had a transporter in a earlier this year with the same issue that we did a video on and have a full playlist on our recovery truck with a built 2.5 in it

[@unscrecon1]

Only clicked because I thought it said “worst Cam girls in existence “ easy mistake to make ..

[@Michael-Gould]

Hate when that happens!

[@Dan23_7]

Those lifters looked like HEMI pistons 😂

[@KarlHyde-dryden]

I’ve just bought a 2006 2.5tdi Touareg, I absolutely love it and for the small amount I paid for it I genuinely can’t complain, however there are a few gremlins about it. I’m about to call you guys to hopefully get it booked in

[@DarksideDevelopments]

You can drop us an email to [e-mail] with reg/vin and we can help you out

[@jemmace2586]

Is right, great videos and great to see another good car back on the road and back to it's best, the amount of time's cars end up scrapped because of some work needed to remedy a couple of issues, is heartbreaking to me. Then again they're not normally from the VAG line are they!?? Personally I love VAG cars and Vans, they're just very well made, mainly, and will look after us if maintained and cared for, so again, great video, really pleasing to see a well used faithful car back to it's best and keeping on. 👌

[@mmllmmll22]

I'd love to see how You manage Volvo D4/D5 (don't remember which ones were bad) from XC90. They were supposed to have like 170/180hp, but due to valves those can do like 130hp. And You can hear how compression goes back to intake

[@matty5057]

Great video as always. Helps this guy is easy on the eye too 🤭

[@AJBORG13]

Awesome 👌 video mate. You've just jacked the price up on them by %30. There built proof and cheap. Easy to work on. How do we get a little more power out of them with simple bolt ons . Ie intercooler manifolds and cartridges

[@DarksideDevelopments]

We've got a fair few parts on our website, from intercoolers and manifolds to turbo kits and injectors all for the 2.5's. Our recovery truck had a fully built 2.5, got a full spec list here - www.darksidedevelopments.co.uk/transporter-t5-recovery-truck-2-5-tdi-bnz/

[@Mistabushi]

Funny how on last video from you guys there were folks defending 2.5 as the awesome engine and cams being “good”. 😂 😂😂

[@dalesmit7869]

yeah, that cam is proper! What is the cause? age or wrong oil or no oil change for a very long time?

[@DarksideDevelopments]

Wrong oil and long intervals, they take 0w30 but plenty have still had 5w30 running through them

[@dirtydenzal545]

Been thinking about getting one of these for a while especially the 2.5 5pot, I believe they don’t run on a timing belt or chain… gear driven which appeals to me what causes the cam issue just poor oil and interval? Thanks

[@TheUberdude14]

ive had head issues regarding the sealing of the pump injectors

[@DarksideDevelopments]

Yes mainly oil and intervals. VW change the oil on the 2.5's to 0W-30 but many still put 5W-30 which can wear the cams

[@TheBrokenMountainBiker]

I almost bought one of these a few weeks ago, was on the hunt for a bigger, taller car and the garage I went to had a 2.5 toureg and a 3.0L X3. I got the X3 in the end....it's now in bits on my driveway! Lol

[@ToyotatechDK]

Lack of lubricant and long oil change intervals. Ivé had several PD´s with well over 300kkm on the same cam. They suffer the same with bad oil

[@neolerades2987]

6:36 - "Like a dream" lol, as a petrol engines owner I would think the engine is about to die and has all the bearings destroyed by the knocking, it really sounds like it has spun all the crank/rod bearings. But that's probably a normal TDI sound, I admire people who can stand it. I already had diesels, but they were all 6-cylinders and they were quiet.

[@GERntleMAN]

Admittedly, that's a sign of poor material quality. But it also looks like not enough oil changes and especially the wrong oil/cheap oil

[@stevenkerry3101]

great work love these type of videos 👍👍

[@adrianware]

Im finding it difficult to even get a garage to look at my t5 2.5 now😢

[@DarksideDevelopments]

If you're in the uk, you can drop us an email to [e-mail] if you need any help

[@lukeparker9548]

😮😮 i always thought the 5 cylinder engines only came in the really old audis and transporters i always though the 2.5s in the touregs were the 2.5 v6s that used to be in the a6s and passats. Well you learn something new everyday 😂

[@DarksideDevelopments]

Good old 2.5 PD 5 cylinder 💪

[@lukeparker9548]

It's a pd aswell well there's something else I didn't know

[@davidhammond8049]

Is there/was there a noticeable difference in performance with a new cam instead? - the next one with a noise cam that comes your way...... please Dyno before and after. Kind regards David p

[@DarksideDevelopments]

Most likely little to no difference. It will feel a lot smoother to drive but wouldn't have lost enough power to be noticeable

[@richardhunt1384]

Could you fit a stainless steel 5 branch manifold (im assuming the exhausts fail(??))to these?😮

[@DarksideDevelopments]

You can, we include one in our turbo kit we do for the 2.5's

[@philhodgson4752]

Good old vw chocolate cams.. 😒

[@michaelchapman4269]

I’ll never forget the disappointment of having my old 2.5 cam and followers done, seeing how badly worn it was and it making zero difference to performance 😂

[@DarksideDevelopments]

Its very odd how bad they are but still make power!

[@marcpearson3955]

Im seriously looking at buying a cheap 2.5tdi touareg as alternative to a disco for greenlaning and camping but was reading that the 2.5 was a nightmare to work on and that you cant do the cam with the engine in place.. clearly the forums i was reading were wrong! 😂

[@DarksideDevelopments]

You definitely can, a few trims to take off at the rear of the engine then its free to work on. Once the issues are fixed it's a super reliable engine

[@marcpearson3955]

Why would you not change the cam belt when have taken it off anyway? Makes no sense to me

Gear driven mate.

Because it doesn’t have one you donut 🤦‍♂️

[@mewering4567]

Without Special Tools ??

Yeah, you need the timing tools for it

[@Meeliskt77]

This bay can fit 5 litre V10 also

[@-sargntclashroyaleandmore-491]

Race cams 😂

[@modermonkula]

Where did all the metal go ?....

[@DarksideDevelopments]

Majority of the time it passes through the oil and into the bottom of the sump. Caught early enough it should be fine but left for too long and it can be damaging

[@dieseldes6578]

No, ford pinto...

[@Decadentwest]

I’m surprised that all that missing metal from the cam and followers has been circulating round the engine and not knackered everything else! Is the filtration system that good that it’s managed to take it all and stop it from ruining the whole engine?? 🤷‍♂️🤷‍♂️🤷‍♂️🤷‍♂️🤷‍♂️

[@DarksideDevelopments]

They seem to be, many PD's had a cam or 2 and still going strong!
