7 Series - E65 / E66 (2002 - 2008)
Discussion of BMW's 4th generation E65/E66 7 Series flagship. The E65 generated much controversy, due to its radical styling and iDrive user difficulties. Nonetheless, the E65 broke records to become the best-selling 7-series iteration ever, especially after its 2005 facelift.

E66 Misfire problem shuts car off

Hi,

Im having some issues with my 2008 750li. The car has about 92k miles and recently started to turn off on me while driving it.

I pulled the following codes with the Carly App

Engine / Motor

:Lambda probe heating after catalytic converter, function: internal resistance too high / Air mass meter, rationality / Lambda probe heating after catalyst function: Internal resistance is too high Code: 002D13

Differenzdruck-Sensor, Saugrohrdruck: Plausibilitaet
Code: 002D32

Transmission / Getriebe GS 19
Parking brake failure Code: 00507C

I have been unable to find any info on the engine codes listed above. Can anyone provide any feedback on this?

THanks
Rey

I would try using a different scanner instead of a phone app .
Maybe goto your local auto parts store & have them scan it.

I ended up replacing all spark plugs and coils on the car. After doing so the car still misfires and shuts off. The old plugs looked pretty bad. I check the connection at the coils to make sure they were not loose.

Im still getting the following CEL codes

P0301 - Cylinder 1 misfire detected
P0302 - Cylinder 2 misfire detected
P0303 - Cylinder 3 misfire detected
P0304 - Cylinder 4 misfire detected

Pending Faults
P0306 - Cylinder 6 misfire detected
P0308 - Cylinder 8 misfire detected
P0300 - Random cylinder misfires

It appears the plugs and coils were not the problem. Any suggestions?
Thanks,
Rey

Four of the new coils that were replaced were bad. They were causing misfires in cylinder 1,2,5,and 6. The throttle response is off and I will have to clean the MAF to hopefully resolve this.

I cleaned the MAF and replaced a damaged CVV. The throttle issue still persists. I'm getting the following codes

Differential pressure sensor, intake manifold pressure: plausibility
Code: 002D32
LR-Adaption multiplicative area1 (Bank1)
Code: 0029ED
Mixture adaptation, total error
Code: 0029EF
LR-Adaption multiplicative area1 (Bank2)
Code: 0029EE
Mixture adaption 2, total error
Code: 0029F0

The Generic OBD codes are as follow

P2177 - System too lean off idle bank 1
P115c - Engine coolant temperature circuit?
P2179 - System too lean off idle bank 2
P3735 - ?
P3836 - ?

Any help would be appreciated.

Maybe a rather large intake leak or injector seal leaks. That will always show as system lean

I took the car to an Indy shop. They performed a smoke test and found no leaks. The mechanic believes its a bad MAF sensor an possibly a clogged fuel filter. He made a comment that the fuel pressure was at 51 lbs and it should be at 58 lbs. For this work they want to charge me $1022. I declined the work and will pay him the $95 diagnostic fee and replace these parts myself. After replacing these part is any programming needed on the E66?

Thanks,

Bummer seems like a intake leak to me. No programming needed on those parts. Plug and Play
