So we got our first really cold days here in MA yesterday and today and when I started my car last night I got a cel and huge surging in the RPMs. I pulled the car in the shop and got a code for sticking throttle valve. I read somewhere that moisture is freezing in the intake and that's what's causing this. Once the car warmed up all was good but I got it again this morning and again once it warmed up all was good. Has anyone found a solution to this?

 

You can clean the gunk and residue oil / moisture that reside in the intake, you will have to take the intake off or at least get the the throttle body to clean it all out. Or if you live in a really cold area they have this .

Thanks

 

Thank you Ecs I guess I should have looked a little harder. Very knowledgeable info as always.

 

You are welcome. Try to stay warm yourself.

 

It just like ecs said. It is the intake. It was wrongly engineered for cold weather. Go to the Gen 2 stock/problems section. There is a sticky there with all of us that of had this issue. After reading that section contact Mini USA to cover the install. I have so far got them to pay for half.

 

Thank you I have a friend in service at our local BMW mini store. I'll see what I can get him to do.

 

Maybe able to clean it out, seems like this happens every year when we get sub arctic weather blast.
