It's really "herky jerky" and annoying...

I cant say much about "engine when cold..." C4Racer's explaination is exactly how it feels (is) with mine and I dont think its has to do with being cold, I normally have the 'bang'/jerky when slowing to a stop at anytime of the day the key thing is how you apply the breaks - suddenly you dont feel a thing, slowly it jerks to a halt. But to save break pads which are damn expensive (this side of the earth!) I break slowly unless emergency, breaking slowly also comes with the bang effect.. so what can we do!:dunno:

Weasel- Thank you for the technical reply and it at least eases my mind that someone else has experienced this. I was a dealer tech for about 5 years but now I work at an independant, basically a sub-contracter for the shop itself as i'm the only factory trained BMW tech locally here.

I do have GT1 with Progman which is about 2 years old. I reprogrammed with this but I'm sure it's not the latest version. I may give the Dinan a try if I can find it to be worth the 3-400 bucks...

Since your intimate with your ride I have a couple more questions.

-What tires are you running?

-Do you have any squeaks or rattles? Especially from the rear gate?

Thanks in advance!

I have the Toyo Proxes on mine. I would say these are good for at least 25K miles at least in my driving pattern which is dominated by highway.

My 20's still have the original style michelin diamaris on them, but I'm due for a new set on them and am going with the bridgestone dueler HP's for my next set if I don't get this set of michelin latitudes I'm trying to get a deal with. (and I mean deal!) I'm currently driving on some 18's I picked up for going to the hunting camp, which have the OE michelin energy tires. When those wear down I'll either throw some mud tires on them for the camp or sell the wheels through here for cheap.

Hey Weasel - You're not interested in the Vred's?

Not really... they may handle good, but wear too fast. I am getting the deal of the week on a set of brand new Michelin latitudes anyways... Gotta love my boss! (how many of you guys can say that?)

Unfortunately there is no clear cut solution. In some cases just the software update is enough, in some the valve body, in some the control unit, and some end up with a whole new tranny. I'd say start with the simplest and least costly options, then go up from there since the whole thing tends to be a gray area.
