Anyone had this - it is difficult to describe but basically when reverse engages and you feather the throttle to move backwards the car almost goes with the throb of the engine like the gearbox / clutch is not right and not engaging properly. I have noticed it a few times and my other 35iS didn't do it. Any ideas ... ? I will mention it to the dealer when the car goes in on 1st June anyway if it keeps doing it ... just wondered if anyone else has had the issue.
Pulsing engine when reversing 35iS
- Thread starter SO8
- Start date
I had this on my 35i DCT some years back. A slight wobble upon first engagement for a second or so. They replaced the DCT eventually after trying new fluid and a reprogram. I think I feel it still now and again or it's probably just in my mind having had it on the first DCT.
It was quite mild but irritating. I asked for a replacement as it made me doubt the longevity of the DCT but in hindsight it was probably nothing more than minor movement in the mounts.

Just noticed it does it reversing into my drive - so when the steering is putting the engine under load. In a straight line back it doesn't seem to do it .... more checking me feels before I abuse BMW 
The car is certainly going well forwards at the moment :evil: :evil: :evil:

I experienced similar symptoms with our 35i and manged to alleviate them with an adaptive transmission reset.

It's as though the throttle doesn't like the smaller more gentle movements associated with reversing after getting accusotmed to going forwards more quickly

My wife has a 2006 X3 2.5si auto and it does exactly this in reverse but only when engine is cold. If I give it some throttle it goes smooth again although obviously quicker (a little too quick for the reverse out of the garage). Doesn't do it when engine is up to heat though.

Hmmmm.... odd.... DCT on mine has become a little clunky and there does seem to be a delay in engaging into reverse. I am getting mine booked in shortly. Will let you know how I get on.
