Out running errands, car fully warmed up. Outside temp about 20F. Was on a real long exit ramp that is normally taken at a fairly quick pace. Light at the end was red so blipped throttle and downshifted from 6th to 5th. another blip to swap gears into 4th and then brake the rest of the way to stop. Pushed in clutch as rolling to stop to put in neutral, RPM's dropped to about 200 so gave it a little gas. All fine sitting at the light. Go to accelerate away the car is in limp mode. Pull over, shut it down, let it sit for 30 seconds or so and restart all is fine. Go through a car wash, stop for gas and check codes. Besides the usual P0420 that has the CK Engine light on most of the time is the following: P1685 Electronic Throttle Control Monitor Level 2/3 Clutch Torque Max Error Cleared all codes. Went on with running around town with no issues. Never have seen that one before. Any guesses?
Nathan, I'm sure you did the same research as I, as far as I can guess, it has to do with a combination of extreme cold & torque limiter settings, but that's just a stab in the dark?
I got that code while teaching my daughter to drive. She is learning standard. She stalled a few times and was driving on mostly low RPMs. After a few stalls the check engine light came on. Knowing that we never got much over 2000 rpm and lots of stalling that first day of driving, I figure that would confuse the ECU. Using my scan guage II, I reset the code and I drove around a bit at normal driving and the code never came back. Also, my kid can drive standard pretty well now. Rarely stalls even starting on a hill now
I had this code last fall in pretty much this same scenario. I researched it and saw references to it being either cold or tune related. I am not tuned nor was it cold out and I just dismissed it due to only coming on once.
So far it has not come back. Then again I've not driven when it has been as cold as it was that day. Hopefully was just an anomaly that will not be revisited.
Had my MINI out for exercise the other morning.....mid 20's F when I got the same warning (drive home abet slowly). After about a mile the code cleared and the daily exercise routine continued without problem. So perhaps a quirk of the MINI? Kent
