Hi guy's,

I'm having a problem with my 1998 318is atm.

When I have traction control on the rev's rev up to around 5,000rpm and stay there all by themself, the only way I can stop it is to either nearly stall the car in 2nd or turn the traction control off. If I have traction off it doesn't do it at all.

Does anyone know what might cause this problem?

I have been told by someone that with these the traction control works by restricting the air using the butterfly in the throttle housing.

I was going to just take this apart and clean it up as the car hadn't had a service for over a year before I brought her about two weeks ago. (Don't worry she has had a full overhaul since I brought her :)).

Do you think this should fix the problem or does anyone else know what might be causing this?

Thank you,

Steve.

Hi again everyone,

I have found the problem and thought I would post it here in case anyone else has suffered with the same issue.

Turns out that because I changed the profile on the front two tyres quite alot it has thrown the traction control out.

I needed lower profiles for when the car is lowered and the front tyres needed doing so I got 45's on the front and still running 65's on the rear. This is turns out is what is causing the problem.

Yes this is a rookie mistake but at least I know what the problem is :).
