i've got a 99 328is w/ 180KM on the motor, its 5 spd.
back in the winter i noticed an irratic sound at idle. like a chugging. so a buddy and I ran it through the computer and it pointed to cylinder 2 fault - so i swapped out the coil form C2 and C4, ran the computer and the fault code showed C4. i have since then replaced the coil and for the most part the chugging went away.
Next, in second or 3rd gear i've notced a lot of hesitation if i give it a lot of gas - could my clutch be on its way out? do you think another coil is gonzo's? i have a feeling since i replaced one a chain reaction could have resulted here.
Last, yesterday i was sittiing in idle and could hear a weird mechanical noise coming form the engine. almost sounded like the electronic solenoid form the heat vent was operating - note: my digital controls were all off.
If anyone has any recommendations i would be very greatful before i send this into the shop.
I believe the clutch needs replacing due to the power loss and sometimes over-revving when i drive.
Thanks for your time.
