This morning I took the MINI out for a club meeting, to get a new shifter ball, and just all around fun. All was well until I got off at my exit. Around 2k RPM, it felt like the traction control over ride kicked in. Put it in neutral, coasted, then back in gear and all was well. The next two stop light starts I took off and took the rpms up and had no issue. Pulled off on a side street, and put the car in second and started to accelerate. Around 2500 rpm it happens again. Once the engine got back down under 2k, it went again, not pausing again. Once in the garage, I scanned with my scan gauge and found no codes. No lights, no nothing. Any ideas? Thanks Sean
Check your IC boots, mine did something similar. My boots were worn out and not sealing, funny thing was it seemed only to act up during lower RPM/boost. Just a suggestion, good luck.
Maybe the new shift knob is too heavy or something. Or could it be you went to some club. We at the un-club were glad to see you this morning. When you narrow this down let us know what it was. I have no clue on this one. miniconcarne may be onto something.
The knob is great, as is the unclub. I will take a look at it tomorrow. That part did have to come off before we could put on the new bypass. If that doesn't work, maybe north end wrench?
I'm not sure either Sean, but I'd recommend calling Chad at DT and see what he has to say before you bring it to any local shop. If it's just replacing the intercooler boots or something simple, you can probably do it yourself. My guess though: it has something to do with a sticking bypass valve.
+1 Once it gets boost you could be developing a leak. Do you have a boost gauge? Also, can you creep up beyond 2k slowly, another words, not under boost?
Wouldn't he have a code if he were losing boost that drastically? My DSC has been acting up lately similar to how the OP's is. Does the light for your DSC blink when your car is doing this? Another thing you can try is turn off the DSC and see if the problem is still there. you may have a overly sensitive speed sensor or one that is failing but not quite ready to get you the xmas tree lights.
Not sure if it will throw a code? Good question. And I assumed he would have already turned off the DSC? Good question also. That's why I have the FES modual......no pesky DSC for me
I didn't see any lights going off and did not think to test the issue with it off. I was shocked I was able to duplicate the issue.
That's an interesting thought... if it is ALMOST done, but still grabbing at lower RPMs, this could be it.
Mine worked fine until I pushed the car into positive boost pressure (around 2500 rpm), then it threw a bunch of lights and went into limp mode.
Finally had a chance to pop the hood. It appears the the driver side intercooler boot was not tightened down on the outside. I'm no mechanic, but I think that might have caused a boost leak. Test drive tomorrow.
About $400 for parts and a few hours of labor. It's not that difficult to do yourself... I did a write-up in the MA library with all of the instructions you might need. http://www.motoringalliance.com/library/1st-generation-mini-cooper-how-to-3/replacing-the-crank-pulley-101/#axzz1pcka6KqM Given your loose IC boot, that's probably your problem. Good luck!
Haha, easy. You have more faith than maybe you should, I couldn't even remember to tighten the intercooler hose. I'll look at your right up.
Look closesly at your crank pulley... My mechanic showed me if you take a prybar and can wiggle the pully eassily when the car is jacked up/on a lift, the oem one is on borrowed time....you can look at the edges of the rubber i guess, but i guessing the rubber changes over time from heat/etc and lets go... Kinda waiting till warm weather and getting the $$ to do mine...trying to decide if the extra $$ on the ati is woth it compared to the gel/liquid one (the ati is actually mercury filled, but safe if i remember right).(edit-ati i have been told is not mercury filled by a member, but also an elastomer of some type)
