I have recently had this problem. But i would get a number or errors pop. Engine Fault, DSC and a few others. Vines replaced both Throttle Actuators as well as the alternator seem to have cured the issue.

The work was completed under warranty.

Is not it strange that both throttle actuators got defective at the same time?

according to the tech both had errors for a while but only one had failed and the other was on the brink of failing. The warranty company replaced both so i can not complain..

What error code did you get for the alternator?

They wear at the same rate so its preventative, as jut2nv had his done under warranty so it wasn't a cost decision . The teeth on the internal cogs wear away, it seems to be one of the weaker areas of the M5. General rule of thumb is that when one goes the other isn't that far behind, there is a excellent thread on here talking around replacing the internals well worth subscribing too.

Ror600, Got your PM, but for the sake of knowledge sharing, will reply here if it's ok.

From the screen shot above, there are several error codes which appear throttle actuator related. However, a couple aren't and would seem voltage related. I can't remember from old PMs, did you have your alternator checked?

Yes I did the test from DIS and it is ok

Is there any other way to test?

After clearing the old error codes did not come back but only the siren alarm

The ones on the screen shot are new
