danutt 4 Report post Posted June 8, 2006 sounds like a major leak excuse me for pointing out the obvious just tryna simpithise with you lol hope someone here knows the prob :bounce: Quote Share this post Link to post Share on other sites
bravo 35 Report post Posted June 8, 2006 Had the same prob. Drain hole in firewall was blocked and water wa building up by wiper motor and eventually overflowing into heater system and into passenger compartment. Drain hole is a small rubber tube (rectangular) facing downwards coming out of the firewall above the steering linkage. Check all other drain holes while you are at it - look for them or look in your bentley. Quote Share this post Link to post Share on other sites

topless 13 Report post Posted June 8, 2006 The e30's are inclined to rust around the big rubber grommet where the main wiring loom from the fusebox comes into the car. Drop the cubby open and get in behind the cubby and check there for rust. Water will come in there in buckets if there is a hole there. Also check that this rubber grommet is properly seated and that it is not torn etc. I have found that if you park some e30's with their nose facing downhill, water will gather in the boot channel and leak into the boot past the rubber seal and run directly into the rear of the car without getting the boot wet. Simply parking the car with the nose higher than the boot solved this problem.. Graham's bit about the water getting in through the fan due to a blockage of the drain hole is another I have had too.

topless 13 Report post Posted June 8, 2006 any idea how to sort it (aside from rust fixing?) might just bung it up somehow Depends on how bad it is Gus. I would try to remove by cutting etc as much of the rust away and then making up a plate and glueing it in place with a silicon multipurpose glue as a temporary measure till I got round to doing a proper repair. Make sure the surfaces are free of grease, dust loose rust etc or the silicone will not bond properly. Will Quote Share this post Link to post Share on other sites
M3 Cab 0 Report post Posted June 8, 2006 Had a similar issue with water in the rear seat and floor and in the boot (under battery etc). In fact a crap load of it. I thought it was coming in through the boot rubber when i parked the car nose down the driveway. Found out one of the rear light rubbers wasn't in properly and not sealing.
