Hesitation / Shudder / Vibration

mejori · 02-26-2014, 03:59 PM

I recently purchased a 2007 328I w/sport package with 52,000 miles
I noticed a couple of days after driving that at low rpms (1000-2500) give or take a few hundred, That there is a hesitation /shudder/vibration when accelerating at speeds under 60? NO SES LIGHT. The entire car shakes and if I let off accelerator it will stop or if I punch it, it will also stop. It never does it at highway speeds and it seems worse when the car is warm but still happens when car is cold. I have read all kinds of stuff from walnut blasting to injectors ..coils..etc ..but no clear answers …. just looking for advice not a diagnosis .. should I not keep the car? The day I took delivery I changed the oil with BMW 5w30 and filter and filled the tank with chevron 93 octane. Thanks in advance!!!

I have a 335i, 2007 n54, manual, e93 (to be specific) and I had the same problem, McKenna said it was the transmission, motor mounts, timing (serpentine belt), pulleys and now they are saying it's the clutch. They've had my car for a month and still can't get this shit right. If they can't fix this shit. I'm going to dump the car and get something reliable. Super annoyed.

I had a low RPM shudder/bucking that was a coil pack issue. Replaced one coil and plug and no more issues.

how did you figure out it was the coil without the engine light? can you check it manually if its about to fail?

Perhaps start with a bottle of chevron techron super concentrate, see what happens.
If its the same, change your spark plugs (thats what worked for me).
If its still the same change the ignition coils.
Still the same walnut blast

see what happens from there and report back
I can understand the fustration when no codes pop. Hopefully its just the plugs, cheap diy and thats what worked for me when i had your symptoms.

good luck

You will feel like the car is kicking while idling, just from experience.
