manual bmw cant pull away smoothly ???

[marmite monster]

got my self a e39 manual 528i . sometimes when i pull away i get this kangaroo type thing going on and i have to depress the clutch to stop it happening . to me it feels like maybe some kind of transmission/engine mount needs changing.
is this a common problem ?

cheers

Probably a CDV issue...do a quick google search and you'll see a bunch of posts about this, mostly American. I don't think it's a big deal, just give a bit more slip in first.

yes!!! CLUTCH DELAY VALVE
just found a long post on a forum sounds like that is the problem
cheers mate

off to ebay for a modified CDV

Yep try are all like it, even after the removal of the CDV they still aren't great. Mine was a e46 so it may be a different story for you, it annoyed me so much that I went straight for an auto on my next BMW.

I read a lot about the issue before deciding to get it done on mine (135i). It is a lot smoother now, but it still catches me out every now and again, no matter how careful I am.

Marmite you don't need a modified valve, it can just be removed completely. There are a few diys on the web.

That is why BMWs are driver's cars

Catches me out from time to time. I read somewhere about deposits on the clutch plates and the best thing was to madly slip the clutch from time to time to burn the deposits off.

Only saying what I have read but it seemed to work on my E36.

cant see the cdv being at fault, why would it make the car feel like an engine mount going like the op said, if it was that bad that the car was shuddering and not right i would suspect clutch problem first.

you can just remove the cdv and re fit the pipe into the slave cylinder, takes about 10 mins.

Had this in an E46 330ci sport we had. Very, very annoying and now have an auto in the E39.

BMW + AUTO = way forward
