No throttle control at times
« on: January 25, 2020, 06:50:33 pm »
Has anyone experienced this. In the past 18 months this has happened 6 times. Throttle will be closed, when opened zero response. Idling speed only. Switch off bike completely, start up and all is fine. After first two occurrences BMW had the bike for two weeks, trying to repeat this. Checked what they can, replaced throttle. All seemed fine but recently this occurred again. Except that revs were a bit higher. No response from the throttle. Twice now in last week then last 500 ks no problem??
This can be dangerous. Its happened in road and enduro mode. I would love to find out what the problem is.

Had similar. Very dangerous. Someone suggested replacing the battery. Nothing comes up on diagnostics. Havent gotten round to it yet but will bite the bullet soon.

Its not that kind of no response. Definitely electronic.

It happened first time in the middle of a busy intersection. At least now I can expect it.

Sounds like Boeing had a finger in the design of the throttle software... :biggrin:

That is something that should be sorted immediately by the agents as it is potentially lethal. :eek7:

I read the following on an overseas forum a little while ago and it might be relevant here: "There is a bulletin out that says if certain TPS related codes are present, then the tech is to change the tolerances that the main computer will accept from the TPS. The bulletin has been out since February (2018)."

I would look at the tps as it is the port of first call for the throttle electronics. Perhaps ask the dealership about the bulletin.
