My wife is driving (and loving) her 2009 MINI Cooper which has been a delight and remarkably trouble-free for 10 years. However, it recently developed a problem which has befuddled us and our highly reputable independent mechanic as well.
Under certain conditions the engine stumbles, feeling somewhat like an erratic misfire on one cylinder or fuel starvation; however, the stumbling vanishes when accelerator load is increased. The required conditions are: fully warmed up (10-15 minutes of driving), engine speed between 2700 and 3300 rpm, and light throttle appropriate to steady cruising. The stumbling will eventually bring on the “check engine” light and a P115C error code (Mass Air Flow).
If the engine is turned off for a few minutes (e.g. for a highway rest stop) the stumbling will disappear and won’t reappear until the car has been driven for another ten minutes, suggesting the fault is something remote enough from the engine that it can cool substantially in five minutes. After a few uneventful driving cycles, of course, the “check engine” light turns itself off. Thanks for nothing. On the other hand, this would be how I got it through emissions inspection…
Thus far the Mass Air Flow Meter has been replaced twice and the Throttle Body once. The latter seemed to help for awhile but I can’t be sure because it’s only recently that I’ve pinned down the exact conditions that will reliably bring this problem on. My wife, who does most of the driving, is a bit of a leadfoot and generally has much less trouble with this stumbling.
Our wonderful mechanic would appreciate any ideas or suggestions.

Hey Man, I’d like to have your opinion: What do you think of the E39 M5?
Let me rephrase: What would you think about a 98000 miles absolutely mint condition, owned by an older gentleman with 3 or 4 other cars (the E39 not being his daily driver), with VANOS changed, clutch changed, and everything that could break down been changed as a preventive measure, E39 M5? … For $15K?
Wondering if I would treat myself to a potential money pit here buying this beast (that I already test drove, I’m in Love) knowing that I will not be driving it more than…5000 miles a year for the next two years MAX!

- Jeff S I rented a 2012 Chrysler 200 with the 4 cylinder from Enterprise for business travel and it was not a bad car but I would not buy one. I would have picked a Honda Accord, Toyota Camry, or a Ford Fusion over a Chrysler 200. I have known people that bought Chrysler 200s that had nothing but problems with them. I appreciate these old reviews and miss the old TTAC before it became what it is now with many articles that are slanted toward politics. Don't have to agree with everything but it is good to read an honest review of a car.
- Jeff S The Cybertruck was first unveiled and announced on Nov. 21, 2019. For over 3 years Tesla has been saying that this truck was going to be released soon. The mystique and surprise is no longer there. I think the Cybertruck is hideous but then I am not the target for this. Since its initial unveiling there has been the introduction of the Lightning, Hummer, and the Rivian truck. The anticipation of this truck and the mystique has faded. There will be a few that will buy this because they are hard core Tesla fans and some because it is different but Tesla should have been the first to market an EV pickup. GM is planning a compact EV pickup under the GMC brand starting at 25 MSRP. This should have been Tesla and Tesla could have downsized the Cybertruck to either a midsize or compact truck and been first. Tesla should have been first at the very least to release a smaller EV truck.
- Bloke Wow, this should make a big difference, to those catalytic converter thieves who don't have tools like 'angle grinders' with them.
- Carlson Fan The way the truck drops in the rear and the bed/tailgate become a ramp is genius! I'd buy it just for that alone!!! It would be awesome for loading snowmobiles and garden tractors in the back. However, my trucks need to be able to regularly tow heavy loads long distance, summer & winter. Sorry folks, current battery tech. isn't even close to what it needs to be for me to think even one second that a battery truck could replace my current ICE powered truck. An EV for a DD makes sense , but for truck you need a MUCH better battery.
- Inside Looking Out For midsize sedan it is too small. It basically is a compact car.
