Has anyone solved this?
I am repeatedly getting a P1689 code (throttle monitor 2/3 torque calculation error or some such...). I've seen many posts on many MINI forums (fora?) asking about this, but never seen a clear answer. In almost every case, the car in question has been an MCS. Mine is an '03 MC with man. trans and NO DSC. If I get on it enthusiastically or hold a steady speed at above 3k rpm, the EML light and SES pops on, we go into limp home mode, and restarting returns all to normal, and after a few more starts the SES goes off. The code is always P1689.
Using INPA very unhelpfully only supplies the same info: 2/3 torque blah blah blah. Anyone got the magic bullet?

I would check your supercharger bypass valve. I bet you will find it hanging up and sticking. There was an issue on an earlier pro date that required a new throttle and or engine harness for several throttle faults but I don't remember the codes off the top of my head. But from your description of when and how it happens it sounds like the bypass valve to me.

I apologize if my response seemed snotty- my thanks is sincere. I appreciate any and all "spitballing" to try and get this annoying problem resolved.
I do have one possible lead: in using NCSexpert to read the EMS module, it listed Traction Control as "active". My car did not come with any traction control fitted, and as I understand ASC+T, it will retard fuel and ignition, even shutting down cylinders, if it thinks you are in a slippery situation. So I'm thinking that somehow the car thinks it has ASC, or ASC+T or DSC and cannot account for the lack of input from the relevant sensors?

Okay, good news is I figured it out. Bad news is it won't help anybody. Here's the short course: after many hours of teaching myself NCSexpert from the excellent tutorials found, among other places, on this forum, I combed through my modules looking for something amiss. I finally found it in the EMS module, where at first I though it was traction control. My car hasn't got TC. I disabled it but it didn't do anything but turn on a warning light in the speedo (same as the TPMS light). Then, going through one more time to reactivate the TC and turn out the light, I just happened to notice that the module thought my car had a MCS engine (115kw). I changed that to the 85kw engine, and BINGO- I cannot make the car go into limp home mode nor does the SES light up or the P1689 code come back. I can't explain the miscode in the module, unless it was an accidental cut-and-paste from when my DME was reprogrammed to be a man. trans after swapping out CVT.
So there you go...like I said, won't help a normal car, or person, at all.
