Can't speak to code 63.

Thanks Chowdah....I'm gonna try the test and see what the #'s are....

I just got my 01 M5 about a month ago. I drove it home 1000M without a single issue. Now it goes into limp mode right after start-up. Turn it off, turn it back on and it's fine.
These are the codes from my peake:
4e: Coolant Temp Sensor
6b: Control unit self-test, pre check of drive-by-wire system
E6: Drive-by-wire, throttle position failure
D1: Misfire during warm-up, cyl 5
D2: Misfire during warm-up, cyl 6
D5: Misfire during warm-up, mult cyl

I saw these issues with other M5's, but I wasn't sure if some codes would contribute to others. Any help would be great.

4e: Self explanatory
6b and E6: Possible throttle sensor failure
The others are pretty common and will probably go away when you reset it and see what comes back.

So I got an E39 M5 last year Feb, and between 6 and 12 months ago I was throwing codes on occasion (mis-fires usually, maybe 1 or 2 cyl's a month, at random) and I reset them, and they have gone away. No worries? Did it just need driven (or well-driven)?

Opinions?

ok. I replaced the exhaust CPS Bank 2. I am still getting code 72. Any ideas?

Looks like I have a Vanos Solenoid issue. Anybody use Dr.Vanos to repair instead of replace?

Do a search on Dr. Vanos. There has been a few write-ups and positive comments.

I've been getting 90/91 Fuel Control codes. I'll occasionally see misfire during warmup on multiple cylinders. Car seems strong (no reference to what strong is or isn't) but has a 'lumpy' quality to the running at all engine speeds, esp. noticeable slightly lugging. I thought a bad cylinder or miss, but all sparks look normal, good compression, and no specific cylinder codes. I have some VANOS noises, but no codes for that. The last VANOS code was an exhaust CPS when I bought the car. Replaced it and no VANOS related codes since, although I do have the other three CPS's ready to be installed when I get a chance.

New sparks/MAFs/precat o2/fuel filter/air filters.

Any ideas?

Mileage? Hose condition? What is your DavidS secret menu MAFS result?

107K, replaced oil seperator hoses (top), haven't looked under the plenum, I had 135 L/H on both old and new MAFs (I bought new MAFs hoping for 145, but that didn't happen, and I'd say it drives about the same. I'll have to drive a car with bad MAFs sometime, because everyone comments on how new MAFs = new car)
