Regarding ECU

[Martins84]

Hey! i think i have problems with ECU, because sometimes 3th cylinder not working properly and tachometer is going up and down 500 - 1000.....
I think new ECU is to expensive... maybe i can buy used one...

Where can i find in ABU DHABI???
Maybe you have any other suggestions?



Thanks

maybe its belong to spark plug firing timing which is belong to ECU as i thought.

BMW ECU's are very good they dont go faulty easy

you should get fault code or Check Engine light pop up if you have problem
go and Scane your ECU and see what going wrong

The crank sensor may do this allot ,
Do it the easy way and change the spark plug,coil, injectors maybe and see if cylinder 3 is ok

Good Luck

if you need ECU we can source you one

Your description sounds like a misfiring problem, that's mostly a hardware problem; faulty coil, crank/cam sensors. The easiest way as said is to hook the car to a GT1 scanner...

Thanks.... i did one computer check and that showing 3 cylinder has problem....

where can i do the gt1 scanner .... it is in abu dhabi

u dont need GT1 Scanner it will give u same fault code
u need to check it manual
take the coils + spark plug from cylnder 1 and exchange it with Cylnder 3# and even the injector. if u have the same fault in cylnder 3# its mean one of these thing
Wiring or ECU fault.
and mostly its coil problem.
