my 2006 R53 has gone into limp mode with the codes :
P1688
P1106
P0107

I've already changed the throttle body, the BPV, the map sensor, and the harmonic balancer but I'm still getting issues. Has anyone had this problem before or know how I can fix it?
Thanks a lot!

I'm on mobile and it won't let me add a video link, but here is a video of the problem https://youtu.be/xMofgMcUDsY

 

It sounds like fuel pump failure. It is not taking gas, for some reason or another. Could be many reasons.
Sorry this is not more helpful.

 

Which map....
There is a hot side t-map and a cold side map (which is actually a r50 t-map, but the t is unused).

 

I replaced the one right by the throttle body, I just discovered the other now. Now I'll try to change it, thanks for the idea!

UPDATE: I replaced both sensors and the problem is still there. Any other ideas?

 

The sensors are NOT interchangeable...
And if reversed with the wrong part # might cause your problem...they LOOK EXACTLY the same...but the operating ranges are different.
The hot side map is a special order part...dealer is usually 3 days...

 

+1 Yes, zippy 100% with you on the R53.


For the map sensor one is upstream and one is down stream. Good picture shows the sensors . 12140872679 and 12140872648

Bank one is one map upstream. Bank 2 is the other,
