1200GSA crankshaft sensor recall

[RSavage]

Phoned Vines (Caterham) on Saturday to confirm that my March 2010 1200GSA is not affected by the brake recall only to have that confirmed and then to be told that it is/B] subject to a recall for a crankshaft sensor problem.

Anyone else heard of this?

Nice people that they are, Vines are doing the recall work on Monday. I'm off to the Pyrenees of Wednesday (I hope!)

I had heard about a camshaft sensor recall. Is this something new?

Surely the relationship between the crankshaft and the camshaft is fixed as there is no variable camshaft timing on the GS - or have I missed something?

There has to be a sensor on both so that the computer can figure out which cylinder is on compression and which is on exhaust and fire the correct plug at the right time.

yep mines the same age as yours and it's been recalled, sorry not recalled
but subject of BMW product improvement, problem with the cam sensor and
unexpected and sudden stalling.

In at Bahnstomer on sat as had puncture on rear tyre came up on the TPC it does work.They changed the sensor as it was in there.Bmw are doing these as the came in to workshop.Unless you have had problems on cutting out.
cheers Bob

Had Cam sensor changed on Friday and it has made very little difference so I think BMW need to rethink what is causing problem.

Does not have to be.

It can use the wasted spark method whereby it fires both cylinders together and you've guessed it - one of them is wasted

Of course you're right about that, and that would be the perfectly esnsible way of doing it to keep everything simple, but that's not how the Beemers work.

My understanding is that they have a crankshaft AND cam posisition sensor. I think that they design these bikes to have as many failure-prone devices as possible. Seems like that, anyway.
