Re: F10 - Misfire on engine

which workshop did you go to?

what diagnostics did they use?

are they familiar with BMWs?

probably just a faulty ignition coil which costs less than $200 to replace (excluding labour).

lesson: only go to workshops that are familiar with BMWs.

I went to my PI workshop at Sin Meng and the other one at Juzz for Car.

Thanks bros for the kind advice, if ignition coil faulty, will it cause pressure drop? My piston 1-3 pressure at 175 but piston 4 at 30 plus only. Thanks again!

Re: F10 - Misfire on engine

So new (3yrs max) and piston leaking ?
What mileage is your car ?
Still within warranty period ?

Re: F10 - Misfire on engine

Pressure drop not coil pack issue ........ Looks like an overhaul is needed.

Re: F10 - Misfire on engine

maybe just need to change the pistons ... piston crack ?

or worst scenario, bore crack =( .

Re: F10 - Misfire on engine

Ring worn is most likely
Piston or Bore crack then we can present it to BMW and ask for answer liao, they probably want to take back engine to study it further.
TS, you go ask Pi if they want free advertisement should they not honour warranty

Re: F10 - Misfire on engine

faint..... my PI workshop told me confirmed the problem is ECU and i have ask them to sign an agreement that if after changing the ECU, the problem still there then i will not pay them a single cents. ...... i just hope by changing the ECU will work!

In any case, you should not pay a single cent. The ECU should be covered under warranty too. Can PM the PI and workshop name to me?

Re: F10 - Misfire on engine

Hi mine also got this problem .but I was lucky . Mine got warranty from performance motor. Did u install kellner sport modules.? My car was 1.5 year. Also went to the juzz for car first than they told me to go performance to check. I wait for 1 1/2 month to get it done.
