engine vibrating

[bikerz]

i juz take my car from AB for changing my radiator, water pump and thermostat. it was ok until i drive to p'jaya. there, i parked for about 8 hours, and it was raining. i start my car that night and the engine is vibrating and the sound is not so smooth. i assume it is bcoz of the engine is cold. This morning i start and it still occur, even i had drive for about 5 min. So, actually what could be the prob? there is no symbol lit up on the meter console.

ok, went to AB and they change coil no.5. engine is smooth. drive for 5 min and then problem occur again. back to AB and they change coil no.1. smooth for another 5 min.

AB says they out of stock. They recommend to change all new coil. but does coil is the main prob? why does it burnt one by one?

The coils surely will fail at certain period, once one is "kaput" then the rest will surely follow, just like the plugs, we always change all of them at once. Actually you can just buy those at BMW spare part shop for example Bavarian Auto....very easy to install so can just DIY. If I'm not mistaken Bosch coils cost RM140 each

Run a diagnostic, it should tell you which cylinder is misfiring. Funny though that coils are failing one after another.

prblem with AB THEY JUST SIMPLY ASKED YOU TO KEEP CHANGING

that's why, i'm abit suspicios izit coil problem? bcoz one will fail after new one install. never two coil fail at one time. so i afraid changing all new coil won't solve my prob.

i had problem my program corrupted. The AB asked to change the ECU instead of reprogramme which i refused

I insisted to reprogram whcich cost me a penny instead of RM5K

one of my friend has the coil problem as you... one coil failed after another new one installed. He decided to change all the coils after the 3rd coils failed. Problem solved at the end..

Had this problem before, one of the ignition coil failed..I changed them all instead one. Problem solved. It costs me around RM145 per coil.

problem solved, sent back to AB, and they said only tighten the coil (i don't believe in that, as it took 3 days to do it and they had change my coil twice, can't they see my coil is loose?) maybe they don't want to show their mistake.

however, now my car is fit, no prob, had been running for 2 days. I wanna say thanks to AB coz fix it at F.O.C

hi all,

i'm a newbi here...just to ask..if the engine vibrate..can we still drive and run it? i have similar problem today...no indication or warning pop up...in general, it will vibrate at low speed..apporx 30km/h below...frankly i'm not sure the source of vibration...could the solution be similar as well? FYI, i notice everytime i warm up the engine at the first start every day, the vibration occur about 30 seconds and gone..it happen lately before obvious vib as i mentioned earlier..

Hope to get advice from u guys...
sorry to park my post here since its within the same topic...Tq
