Jumpy Leaky 318is

[Big Al]

Hi, am new to this forum and have a 93 318is with a few problems I hope to get some advice on. First problem is a jumpy rev counter along with a loss of revs for a millisecond, the rev counter jumps up and the engine seems to miss - I've recently had the cam position sensor replaced, the ABS sensors and a second hand ECU put in. This used to happen only when travelling over bad bumps at low speed - its now happening less often (also had both rear shocks and mounts replaced) but is really annoying.
Second problem is that after rain I am finding water pooled under the passenger side carpet - mostly at the back but also spread towards the front; the boot seals seem fine so its a bit of a mystery.

would really appreciate any advise - thanks

As for the jumpiness you're describing, you might want to clean your obc, for information on how to do that check the faq. As for the water pooling in your car...
I just recently stripped and chopped up a wrecked 325is (same body style: coupe , but 6-cyl engine). There are drainage tubes in all of the roof pillars A, B, and C. Its possible that one of those is leaking, they extend all of the way up to your sunroof, If you've ever had your headliner down you'd know exactly what I'm saying. Or, it may be that your window is not sealing properly, its happened to me before...

Thanks - I will have a look today and let you know. The water leak may be the window seals, they are perished in some parts - will get the hose pipe out to see if I can find it

Maybe clogged with crap so the water dosen't drain, spilling over into the cab?

its possible, especially if the car has had its sunroof cassette out at some point(possibly before you got the car), they may not have been re-attached the drain hoses properly. I'll tell you its probally not because the car has rusted because when I chopped up that 94 325is it had coating on the inside of the pillars and frame, I doubt its because you have a rusty hole somewhere. You tend to discover a new appreciation for the engineering that goes into these cars once you totally strip and gut one. German cars rock!

have had a look and still can't figure out the leak - no sunroof on the car so thats out, doesn't seem to be any of the seals although I noticed a small gap between windscreen and the well by the wipers that I have sealed with tape to see if its that (not a good look having gaffer tape all over the place). Will try the drainage pipes behind the firewall to see if they're clogged, otherwise its a case of keeping it out of the rain - not easy when you live in Manchester!
