Bro jarance and eujinee right on the money...

I checked with other forums and it sound like :
#1 Cam + crank sensors
#2 Failing MAF

#Bonus : She found out ur cheating on her... (explain to her about driving other car should be ok )

BTW some of the E46 simple start up diagnostic fix are the "dry solder" on MAF curcit as well as on the cam/crank sensor circuitry... do that first before you replace anything...

bring us back with the joyous news

"Dry Solder" on the circuitry... hmmm i heard this from other forum but did not know exactly where to start looking for it... but its on the circuit of the MAF and the Sensors of both items...

"Dry Solder" happens when the electrical circuit is disrupted --> hence the person/mechanic asked you to change ECU, this sensor that sensor... etc etc etc...

Might be of help... but then again ECU reprograming might do the trick...

Ive read that a lot of people change item without positive result... save ur money more... fix whats broken.

m3addict,

changing the valvetronic motor is not a straight forward job.

It involves removing the cylinder head in order to access the servomotor.

It is advisable to send to a specialist workshop to get it done.

No point guessing for the answers here and as what Jarance has suggested, send in your car to a specialist workshop and have it done.

 

[M3addict]

thx all for ur opinion.....
if it need to remove the cylinder head for the job to be done, then need to wait for fund also....
now think just keep at home for a moment.....:2:
