When changing gear the revs are holding for just a second which means you can't do quick gear changes. I thought this might be to do with the extra reciprocating mass of a 6 cyl as I'm used to a 4 cyl but after watching others on youtube I think it might be a fault with my car.

I don't think its a sticking throttle cable because that would usually make the engine over rev between gear changes.

When going from first to second, especially if I giving it some, it seems like I have to wait ages for the revs to drop before I lift the clutch.

Anyone else had this?

Remove the air intake pipe and clean out the throttle body with carb cleaner. Is it worse from cold?

 

[maxwe789]

It seems to behave the same hot or cold.

I'll give that a go, and let you know how I get on.

Thanks!

Do that first, i had the same prob on my 325. I cleaned the throttle and it made a difference but still wasnt perfect.
I ended up changing the throttle position sensor to cure it :thumbsup

I've got a few scrappers round here, worth getting a new sensor or scrappers be fine you think? I'll probably get one because even if it has improved after cleaning the tb I'll still wonder if it could be better...

I paid about £40 for a new one. Ill be keeping an eye out for a spare one though because they can be a common fault.
Keep us updated how it goes :thumbsup

I would also check any vacuum hoses for leaks as well.

I thought I had a similar prob, but have put it down to the valve that stops the clutch engaging quickly

You have a pedal position sensor here http://www.realoem.com/bmw/showparts.do?model=CC32&mospid=47446&btnr=35_0165&hg=35&fg=15

Otherwise the rest is built in with the diesel pump
