Hello everyone,

I'm new to this group/forum, though I have owned my 04' Mini Cooper since, well 04'.
I have now finally decided to ask all of you some advice.
I've had this problem for awhile now, and hadn't thought to ask the forums, so here it goes.

I've searched, and this issue doesn't seem to be related to the Yo-Yo problem, and mine is not a Mini S. and it only happens at a stop.

Here's the problem

At a stop, with the brake fully depressed, the car feels like it's trying to get going. and all that's holding it back is the amount of pressure I have on the brake. It continues to try to jump forward, it doesn't actually break loose, but studders. This happens on a daily basis, taken to the dealer a few times for it over the years, and all they tend to do is reset the computer. Is there a thread that I didn't find relating to this problem? I'm coming to the end of my patience, and i'm either hoping the new models will have this issue fixed, or i'm thinking about other vehicles, though it hurts to think about.


any and all help would be great

thanks

 

Based on your description, it sounds like the car is an automatic. I'm not familiar with Mini's but, on other cars it could be many things.

1: Idle Air Control valve (sluggish opening/closing causing a surge in idle speed)

2: Any number of transmission sensors causing a ruckus to include the sensor that locks up the torque converter.

3: Since it's a 2004 and an auto, I assume it's a CVT, right? It could be a problem with the innards of the transmission. I don't know if the CVT uses a torque converter or not. Possibly the belt getting grabby?

4: Do you keep the A/C on? Stay in defroster? It could be the A/C coming on causing the idle speed control motor to kick the idle up and that idle speed motor may be reacting faster than it's supposed to due to wear or, maybe it's sticking then suddenly knocking the idle up.

Like I said, I'm not familiar with Minis in particular but I've worked on cars, trucks and pretty much anything else with an engine for 27 years so the above are just a starting point. A shot in the dark if you will.

 

Just put the car into neutral then back to D when the light changes.

 

It is an automatic, sorry, didn't specify that.
and yes it has the CVT, so no torque converter.
I do not keep the A/C on, this happens even during the winter time, so no A/C needed. But this doesn't sound like a common problem? Has anyone else had this issue? or something simalar?

and i used to to the neutral drop in an older car,
that transmission didn't like that very much.
