Just got these dreaded warnings this afternoon!ouich the first one happened after I had been driving about 15 miles or so, nothing excessive. continued to my destination and left her alone for about 30 minutes and started her back up... everything seemed ok. I even stayed in P400 mode, then on the drive back home got both warnings!!?? :sad2:
and yes I did a search on the subject.... just wondering who has had similar experiences... and if there is any chance it will "self-correct"???hmmm

You should really take it to BMW ASAP. My 2007 M5 did the same thing and completely died on the freeway. BMW Germany was prepared to install a new engine, intake and header set. After refusing that deal, it worked out as I received an M6 for my trouble.

Believe it or not, the same engine malfunction warning light came on in the M6. The dealership put the car on the computer and it was simply a misfire. So to answer your question, in this instance, it "self-corrected". This hasn't happened again, so the M6 is in good shape.

Well good luck!

if it were just increased emissions warning and not reduced power with lower redline (limp mode) I wouldn't get worried about it. But with limp mode there are several possible sources and it's better to know what it is before assuming it's no big deal and waiting for it to clear itself. They should be able to tell you what is causing it readily by looking at the fault codes on OBDII. I say bring it in.

PS. NV M6's experience sure ran the gamut. One limp mode got him another car, the other meant nothing. :dunno:

Dinan Cold Air Intakes?

I assume you have the Dinan cold air intakes? I had them installed. I have heard that the filters inside the airbox can come off (some of the first ones are doing this). It is good the car recognizes this letting us know, and we don't go around driving the car without the filter in place.

It does make one wonder about $2500 airboxes with falling off filters though....

:cool2:

Hey, welcome back! My engine malfunction, reduced power error message went away completely immediately after I had the throttle bodies replaced. I never had this message again, but when I brought it into Ron's shop for fluid changes, as a precaution he checked the intakes and noticed that one of the filters was loose, and he made the necessary fitment changes in the housings of both filters. It just goes to show how quirky our cars can be, since I still had full power and no engine malfunction message even with one of the filters being loose, while you still had the error message. I did have the increased emissions light however, which at the time I brought it in was only localized to one bank of the primary catalytic converters (as opposed to both banks, which I have had since this past winter), and on the same side as the loose filter. I would be thrilled if the combination of the replaced TB's and fixed intakes solved my increased emissions problem once and for all. The fault codes were reset, and so far so good. Not entirely sure, but I think it takes 500 miles before the light comes back on after being reset if there is still a problem. I have another 150 miles to go and am keeping my fingers crossed.

That same error message can come on from something as simple as the gas cap not being on properly. It happened to me when I first go my car. A quick warning reset at the dealer and a resetting of the cap and it's been fine ever since.

I was told by my dealer that a hose is causing the problem. As of Friday 8/23/08 there were close to 50 of these hoses on national back order. I am wondering if this needs to be a TSB (technical service bulletin)?

Happened to me once, after pulling out of the gas station. I pulled over and shut the car down. Waited 30 seconds or so, and have not seen it since. I chalked it up to the fact that we are driving highly advanced computers, and it just needed re-booted. Will see if it continues to occur.
