Or lower arms….pls guide me….dear sifu’sRegards mikeraj04

It could be the gear position switch problem or gear box problem. If using BMW Scanner 1.4 to scanner and shows u Gear Box Switch, then the gear position switch having problem.

Thanks bro, will check on that, btw yesterday after switching the MAF, still the same problem, and he told me that manifold got some air leak....so ask me to change all the hose and check....i will also ask him about the gear box switch

thanks bro

What happen if change the hose and still the problem persist?

If gearbox problem light comes on, he should look at the GB module and not at the ECU module

true.... some mechs r too depend on scanner, sometime small technical issue also will cause fault code

Engine stalling and GB problem are not related.

thanks sifu, so what could be the problem then, when he diagnose no problem with the GB.... today test the for about 200km no problem....sifu just wondering the worse senario

if there is a leak in the vacuum hose, it will sometime stall the engine.

changing the hose is not expensive but changing the MAF is expensive.

btw, what the symbol that light up? are we talking the same thing?

 

[jarance]

or this.

hai jarance this what the problem is

mike, here is the advise from owner manual.

The GB will auto reset if the fault is just a glitch in the system. (unlike E39, the GB do not auto reset)
However, the GB module will capture this error and store it. You should be able to read this error from the
GB module. If you cannot read it, somebody could have erase it when they scan the car.

Nothing to worry about because your problem with GB did not return during your last few usage.

Just check for the vacuum hoses for leak and change it. It wont cause you a bomb..
