Hey all, first post and am in need of some serious help. I have an 09 cooper s. Bought it 2 weeks ago and haven't drive it much as I've been busy. Took it out for a cruise and got on it and threw me into limp mode. Usually happens at 3100 rpms in only 4th 5th and 6th. Went to a bmw performance shop and they ran these codes::

Lmao. So yeah that's what I'm dealing with. Any suggestions would help. I've tried a new battery and had the alternator checked. All fine. I seriously hope this happened to someone so I can just get the part and fix it , cause I do t have 2-4k so throw at a dealer find the problem. Thanks!!!!

 

Also it was in a minor left front collision. Said it wasn't bad.

 

First thought was battery, but...
Too many voltage errors in too many different locations to be as simple as a faulty switch, relay or sensor. If there was improper repair of any damage done to wiring from the collision there could be some very confusing signals that the ECU just can't unscramble. Modern computerized cars don't take practical jokes very gracefully.

 

start with a battery and go from there and or a loose ground wire.

 

Haha. No joke. So do you think this would be a some what cheap dealer fix. Or are they going to milk me for what I'm worth? The shop that I went to seemed pretty decent. I really don't know where to got from here lol.

 

Changed the battery already.

 

I just don't get it. For me to be able to bring it up to redline (if I so pleased to do so) in first and second, but third is iffy. Sometimes I can take it to 4500 rpms but lately it seems to be consistent just over 3k rpms to go in limp mode. Just don't understand why first and second are fine.

 

Just trying to think outside the box here.

Your engine speeds vary in all the gears, you can run it up in 1st and 2nd but above that then you have issues. Well, 3K (or whatever) in 3rd the car is moving through the air a lot faster than 3K in 1st. Which led me to thinking maybe it is indeed a wiring issue, and the act of the car cutting through the air at a faster clip in the higher gears is adding vibration to a damaged/faulty harness or connector somewhere that is in a position to be impacted by the faster moving air.

 

Others may not have it in them to say it, this isn't going to be cheap! Why on earth do you think the guy sold it to begin with? Hint, hint... This is my case why buying from a reputable reseller (like CarMax) with an extended warranty plan to cover issues you're having is a good thing, the warranty might now be cheap ($2800), it's a lot less than you'll pay out of pocket! Electrical issues with Mini's is very troublesome, these Mini's are extremely sensitive. Electrical problems with any brand of car is sometimes worse than mechanical problems.

Hopefully this is a lesson not to buy a used Mini from a private party without a warranty, buying a used MCS with N14 engine is the worst used you could ever buy used as of right now! He even told me that he tried to communicate with the corporate office of CarMax to stop buying and selling Mini Coopers because it was ruining their reputation. CarMax corporate didn't agree because their making a **** load of money. If you think about it for a second, ask yourself if you were a successful vehicle reseller with what you know now would you continue selling Mini coopers that could quite possibly tarnish your reputation?

When I first drove my MCS off the CarMax lot they give you 5 days to return your car for a full refund if you're not happy with it. Who does that?

 

Most of those errors are even present (they are probably mostly old errors that should be cleared out)

I'd concentrate on the first one: the charge-air one, it is probably the one that is causing limp mode. Look for cracked or leaky boost tubes. Could be a MAF sensor.

Check this thread out:

You've probably already done this but clear all codes drive it and see what codes you get and work from there will be a lot less confusing and you can focus on the current problem.

 

Yeah. He's having kinda the same issues as me but without the massive code readings. They have all been wiped and all comes back the same. Car boosts fine in 1&2. So I see no issues there. I'm stumped. I guess I'll have to wait til I have 5k to dump into it. Sigh

 

DME: Charge-air pressure control deviation, plausibility


I just got that same code that threw my car into limp mode in the higher gears during spirited driving with twists and turns and uphill climbs. It just happened during the Mini Takes The States event while we were in Colorado headed towards New Mexico. Luckily Mini provides a Master Technician to help any cars that have problems. He found that there is oil in my intercooler that my regular mini tech did not find when replacing my failed turbo a few months back. The higher gears require more air and the spirited driving caused the oil to slosh around inside the intercooler and temporarily blocked the charge air for a split second causing the revs from the turbo and engine to not match and throwing the car into limp mode. He cleared the code and it's fine so long as i don't drive too hard. Unfortunately this caused me to have to back out of the MTTS event and head back to Utah to have it serviced.

 

it was in a collision? when?
