Customer Question

Hi. I have a 30k miles 3 litre X3, puirchased about a month ago.
At 65mph ish I get vibration in the accelerator pedal and onthe floor.
It's not massive, but there and annoying.
I've had all the tracking and balancing sorted, because it was pulling to the right.
Front tyresa re run flats, rears aren't. I had a dual mass flywheel issue on a n old 3 series with similar pedal vibration. Any thoughts?

Hello, I am Jose Sebastian. Your mechanic automotive expert, It's a pleasure to me to attend your question. Thank you very much for trust in just answer.

Dear customer, have you verified the supports of the engine and transmission? This bases or supports hold the engine and the transmission to the chassis, could you tell me if you have verified them?

I have not. I am taking it back to the garage tomorrow but as they are not a bmw garage I worry they will not pick up or recognize the fault
Expert:  sebastian manrique replied 13 days ago.

Dear customer, I understand, vibrations are commonly consequences of wear on the base/supports of the engine and transmission, these supports are pieces made of metal and rubber when the rubber wears the metal vibrates freely causing the vibration that you present, on the other hand is good to check the transmitter shaft system because if we have problems in the tip of the axle, tripoids or in the bearings can cause this same kind of inconvenience, finally a problem in the front train including supports and rubbers can also cause this type of problems.
Therefore I recommend you that you tell the technician who is going to do it, even if he is not an expert in BMW, to check what i mentioned before.

In summary I would like you indicate the technician:
-Verify the supports of the engine and the supports of the gearbox.
-Verifies the drive train shaft
-Verify the front train system.
