BMW E60 M5 Water Ingress Issues!

[@FernandoSantos-kv1cc]

Good morning. Once again a video about something that no one would think about. Very good. Thank you for the videos.👍👍

[@MTechGuy]

Thanks for stopping by Fernando 👍

[@FraxinusExelsior]

Great video! Water inside a car is something often overlooked and sucks so very much.

[@MTechGuy]

Thanks for watching Allmoge. Yes, something you’d certainly want to avoid happening

[@MarinaIonutz]

Mate you are genius,i think you just saved my life .I was changing the fuel filter and under the seat i had 10 cm of water and i think its the drainage point , thank you mate

[@MTechGuy]

Yes more than likely the rear drain point exit blocked

[@MarinaIonutz]

@@MTechGuy both back ones are blocked but front one as well , could you please advice the best way to sort it out without breaking the pipe ? Much appreciated mate your videos are very helpful 👌

[@MTechGuy]

Glad you’ve found the videos helpful. Follow the guidance in the video, it’s normally the drain exit within the wheel well that gets clogged. You’ll have to remove the wheel liner to access it and give it a clean 👍

[@MarinaIonutz]

@@MTechGuy yes mate done that but i mean for the front drain point , the one that is in the door, i have one of then blocked as well .

[@MTechGuy]

Clean it while it’s fixed to the car, at the point of exit, then flush some soapy water down it

Great narration, really useful info. I have been trying to search for this. My friends M5 got flooded with the sunroof drain clog.

[@MTechGuy]

Thanks man, glad you found the video useful! Super common problem with the E60, hope your friends modules survived! Thanks for watching

[@JunYamog]

@@MTechGuy it survived, but an expensive dry out

[@Edison73100]

Also make sure your two cabin filter housings are seated properly, you will see a gap when you look thru the back side of the hood with it closed if they are not.

[@twinnett1714]

Thanks, MTG, good, clear, straight forward video, with no BS👍

[@MTechGuy]

Thanks for checking out the video man 👍

[@eddiek821]

I know there's a little drainage hole behind the fuel fill flap aswell as when I purchased my 530d it was full of water behind the flap which you deffo don't want then I noticed a little hole full of sludge right below the fuel cap so got a thin piece of wire to unblock it always drained since.

[@MTechGuy]

Cheers for pointing that out Eddie, good one to add to the list! 👍

[@eddiek821]

@@MTechGuy No worries I think it's one that probably no one would ever know is there till it starts holding water had me scratching my head thinking why's this holding water all the time it can't be that bad a design then I saw the hole haha.

[@geoffwalker1531]

Great video, thanks. I have a very wet 535D to dry out inside. So these hints will help

[@shamrich1319]

Why is the wet carpet from the driver bringing the E60 model to the back?

[@cespaillat11]

Excellent video and clear instructions and recommendations. Thank you!

[@MTechGuy]

No worries, thanks for checking out the video!

[@JunYamog]

Newbie tip: I remembered to do this today. I poured warm soapy water. So happy that it was draining well. So I put a few bottles of water, some I was a bit too fast. Eventually there is an overflow on the C pillar. It’s just moist but next time I should put water slower 😅

[@MTechGuy]

Yes, don’t get too carried away!

[@DogNamedNicolas]

Another solid video!

Cheers CS 👍

[@0520994]

I have this problem , but mine is at the back of driver side (Rhd) water is so bad it’s throwing air bag lights on and flooding all the way to driver side floor too. I have no sunroof and still have no clue where the water is coming from .

[@MTechGuy]

I would start off by removing the door cards and inspecting the vapour barrier for tears and no being stuck down properly

[@0520994]

@@MTechGuy thank you . Will do ASAP

[@eddy45686]

@@MTechGuy I’m assuming you can test door cards by hosepiping the windows and checking if water comes out of door instead of drain hole. Or sit in car and wait for water to seep in. I couldn’t see water come in so I’m assuming mines from windscreen cowl area drivers side.

[@nathanparfitt3038]

Did you find the problem?

[@lewis72]

16:12 I don't understand how rain water gets into the cabin from the under-bonnet drainage holes. The height from the drainage hole to the cabin air filter is quite high, so that would take a lot of water to accumulate before any water got in through the cabin filters. Is that the scenario that you're suggesting occurs ?

[@MTechGuy]

The vehicle has brake booster linkage, electric cables and hood release that pass through the bulkhead below the micro filters

[@lewis72]

@@MTechGuy Ah, OK. I'll take a better look tomorrow. I've got mine partially disassembled.

[@MTechGuy]

If the vehicle is out in pouring rain, it doesn’t take much for the compartments to fill up with water if the drain points are blocked

[@lewis72]

@@MTechGuy Yes, it was out in the very heavy rain that we had a few weeks ago. Furthermore, the car was parked half on the kerb, so more rainwater would have gone onto the RHS drainage, which was the side that let in water.

[@lewis72]

@@MTechGuy Thanks for your video. 17:22 What's the 2nd electrical connector for ? I have the bonnet sensor on mine but not the 2nd connector. What had confused me is that there are 2 drainage holes on each side. - The first, which is cabin-filter level, goes outwards into the inner wing. There is an rubber elbow hose those channels the water into the wheel arch area. I think you looked at the underside of this from the wheel arch. It is removable from under the bonnet but it takes a bit of heaving. Mine were full of mush on both sides. - The second is at a much lower level, as you showed, below the brake servo. I _think_ that what was happening with mine was that that lower trough was filling with water by a few inches and then the water was getting into the cabin from the brake servo hole, not, as I first suspected and thought unlikely, through the cabin heater vent tracts.

[@craig1000]

Hello Mtech guy. Wondering if you can create a video in repair the door sill trim light after failure or point me in the right direction to whom repair these items thanks.

[@MTechGuy]

Super common problem, usually best solution is to replace it with a new unit, but normally it one be long until one of the others go out!

[@b12khx89]

Going through the history and receipts, mine had water ingress in the boot area in its life time which was sorted.... Quite a common problem

[@MTechGuy]

Yes, super common problem with the E60, more so than what’s often discussed with these cars

[@groupb5420]

I’m waiting for this f.... Ing weather to stop raining so I can check mine because it sits on the driveway which I don’t like but have no choice.. I did use a cover when I first purchased the car but this caused water marks in the paint ( waterproof as well ..supposedly) ..... I may look at a low profile car tent if there is one

[@MTechGuy]

I’ve been in the same position with many cars over the years. I’ve found washing the cars frequently helps, like once a week no matter what, or straight after a storm

[@soundseeker63]

Those non-return valves are silly, why did BMW fit them there? It's not like any muck is going to make it through the arch liner and get up into the pipes... But it does mean the pipes slowly block up with dirt coming down from the roof. Think I would just pull them off and leave it at that as the fronts ones dont use/need a non return valve and as we know, and not prone to blocking up.

[@trader891]

Great video! Water poured unto windshield was leaking into cabin, but I had no idea it was filling up chambers around the DME and brake booster which both had badly clogged drains. I thought is was leaking through firewall somehow. I had to replace my wheel wells anyway, so i took them out completely. 2005 525i with manual transmission.

[@MTechGuy]

Good find!

[@StephenRod]

Better late than never.. I'm a subscriber and a new (to me) E60 M5 owner. Thanks for all the videos, its been so helpful! Question for you - I discovered a bit of water in my battery compartment in the boot area. The water was collected in the dimple area of the tray in the corners. I haven't felt any water in the boot itself. Any idea where/what the culprit is? Thanks - Stephen (Washington State, USA).

[@MTechGuy]

Thanks for the Sub Stephen, good to have you here. Congrats on the M5 purchase! The water could be getting in the tail light gaskets, rear window seal or the boot/trunk seal. I would start by checking the battery drain & grommet it goes through are in place, then remove some of the boot interior panels and give the outside a good spray with the hose pipe. The leak should be relatively easy to spot

[@syedshah342]

I've got a2010 e61 520d msport and the leak is in the front driver side and it's going into to passenger but this has damaged my foot pedal. Do you have any videos for this

[@MTechGuy]

First use the advice in this video to eradicate any leaks, then you may have to replace the pedal unit if it has been water damaged

[@ObbardProductions]

my 2006 bmw e60 didnt have any drain plugs under the rear wheel arch liners, it just had a blanking plate over it,

[@MTechGuy]

Does it have a sunroof?

[@ObbardProductions]

@@MTechGuy No there's no sunroof

[@MTechGuy]

@@ObbardProductions OK, that’s why it’s blanked off, because them drains in the rear arches are sunroof drain

@@MTechGuy Oh I see, thanks for that. excellent tutorial by the way, I didn't think about cleaning the drain valley by the boot, it seems to of fixed my faulty right indicator now. thanks.

[@eddy45686]

Got wet drivers carpet. Totally soaked floor. Is this the water coming via windscreen drivers side drain point. Do we need to open up drivers side wheel arch like in video?

[@MTechGuy]

Yes

[@eddy45686]

Ok tried that and water flows and exits the rear wheel arch when you pour down windscreen on both sides driver and passenger Under brake booster no wells or water seems dry mechanic says. Pouring down windows haven’t seem water pour into footwell unless it seeps under carpet? Mechanic is puzzled not sure where the access is. Says could be lights anything where it’s coming and maybe needs all plastics off to see. We have no sunroof too. Any ideas as I’m getting puddles daily after rain in driver side front and rear no where else.

[@eddy45686]

Ok so 2hrs later I have a puddle seems it’s the door leak.

[@MTechGuy]

Cool, yes at this point I would say door drain point leak, or the door vapour barrier not sealing

[@eddy45686]

@@MTechGuy went to body shop guy and he poured water on windscreen and drivers door like a rain shower. I sat in car for 5 minutes and could not see any water seeping in via doors or behind pedals. Above the pedals it’s totally dry but the floor is wet. I put on cover overnight and water still enters . The cover is over the windows and front bonnet. However bonnet is not secure wind can breach it by blowing under but doors are covered to below windows . I’m totally puzzled by this. Going to have a another look under bonnet cowl as my incompetent mechanic tells me is all good when he didn’t even put plastics in right. If it’s not bin Under bonnet under brake booster then I’ll lost. I swear it’s not doors as he literally washed them down. They soaked now but how did the water get in to footwell when no evidence of ingress via opening???

Quick question: while trying to pull drain plug out my friend used a screwdriver and accidentally pushed it thru the hole it sits on. Now water drains out but not sure where it exits under car. It’s seems to run under cover I think and traces of oil is on water presumably water picks it up from underbody cover. It’s not draining from wheel arch for sure. Is this ok or should I investigate that rubber seal plug which is going to block again if we find it ??

[@MTechGuy]

Depends which plug it is. I’d reinstate the plug

[@eddy45686]

@@MTechGuy it’s the drain plug under the brake fluid reservoir/booster bin. Without plug it drains quicker. Will need to buy another plug as it’s lost probably in wheel arch. I’m assuming it’s same plug that drains to underside of wheel arch and no pipe is connected. I’ve seen plug in video and it looks like it has no connection on drain exit side.

Yes, the plug just diverts the water in one direction. Has your interior stopped being wet since the plug was removed?

[@eddy45686]

@@MTechGuy Had covers on so not tested yet. But I’m hoping it’s solved it. Carpets are little damp other side passenger so going to attempt under ECU box but heard it’s hard to see drain in there. If I see water it’s also blocked otherwise drain will be clear . I’m told that even though drains are clear water can still seep through thru blanking plate which lets in wiring looms/data cables in. Common problem and specialists replace the blanking plates first.
