i Drive problems / frying of electronics by water ingress

Checked for these pipes today but couldn't see them, Did they remove them from the LCI E61?

 

All areas apart from under the battery seemed dry. I could see a few MM of water under the battery - do we think this could be coming from these blocked pipes or from somewhere else?

Quick question, I was getting a little water in my battery compartment so have just replaced the tail light gasket. However I checked behind the felt stuff and I have no drain tubes as I've seen in other photos. Is this because my car doesn't have a sun roof? Car is E61. Just want to check there's nowhere else water can be getting in.

 

I seem to be having this issue, is the tail light gasket easy enough to buy and replace?

Yes, from memory it cost about £13 from the dealer and fixed my leak.

Not particularly, but if you take off the old one you will see the problem. It's made of foam so when removed after several years you can clearly see the indent from where it sits between the light and car body, so all it would take is a tiny gap somewhere. Replacing mine definitely solved the problem, a year later still no water in the battery compartment.

Another question if I may! did you replace both gaskets/seals (as in, both sections of the rear light) or just the section that is attached to the body of the car? thanks!

I'm pretty sure both the E61 and E60 only have one rear light unit per side? I know some other BMWs have the unit split in two, one part on the body and one in the boot lid. But my E61 lights are one whole part.

 

EDIT: correction, just looked and seems I'm wrong. So in that case I only replaced the body gasket.

Thanks, just took a look at mine and the foam does look quite old. Will replace this and keep an eye on it as I can't see any other place where water may get in?

I had an interesting leak on my E61 some time ago. Car wash pressure lance overcame the rear door seal and filled my spare tyre compartment with water. Car died over a month. Problem was all the modules in the compartment were under water. £600 to replace damaged modules. Leccy found that the leads to the modules were long enough to relocate modules into the rear wheel arch space . Watch the car wash characters.

I really should have read this thread before I started messing with the car at the weekend but nevermind. ;)

 

Mine is an '09 LCI E61 non-sunroof. I recently had the suspension relay stick on due to the paddling pool filling up so I was planning to remove the plugs from the bottom of the legendary drain pipes and everything would be sorted. But of course I don't have the drain pipes as I haven't got a sunroof - I did stop looking eventually but I won't admit how long I was hunting for!

 

What I did find was that my battery was also sitting in 4" of water so I have removed the 4 plastic grommits/plugs from the bottom of the compartment. I figure I'm not going to get a lot of road spray up in there as it is cover by the air compressor tray. 

 

I had considered drilling some holes in the wheel space floor as insurance but I found there are actually small louvres in there already which were covered up with a tar-like gunk. I opened these up and they drain wonderfully into a second skin channel under the boot which then empties onto the ground. Why on earth did they decide to cover these up!?! 

 

Last job for the day was to remove the ECU and poke out the remaining scuttle grommit at the front. Done - but I'll add further comments to the scuttle thread. 

 

cheers all

Mark

I have an 09 e61 without sunroof and was also looking for longer than I'd care to admit... long enough that I didn't get time to remove the trim from the wheel well to check it and wasnt going to bother seeing as I couldn't find the pipes... I guess I'd better go have a look this weekend!
