I just sold my car earlier today. The guy is on his way home and the car keeps going into limp mode. He says there is no SES light. He can drive about 15 min before the car drops into limp mode. It is over 104 degrees out and he was driving at 80 mph if this means anything. Anyone have a shot in the dark at this one. He is still on the road as of 2pm eastern time.
Sorry, you need to have any CODES that have been recorded. Otherwise, it could be a number of things.
My car was running at very high speed in Nevada, uphill, A/C on, and the outside temp was 117 degrees (confirmed on the radio). NO PROBLEMS WHATSOEVER.

My car has kicked into limpmode twice on me while leaving the house, dont notice until I get on main road and try to use gas...
Both times no SES light, and no codes showed up when I did an immediate Peake scan (with car running in limp mode still)...
I know thats not much help but...
Hope it clears up for him... Maybe its the car saying that it misses you!

My car has never gone into limp mode. Do you know for a fact that the guy wasn't hot-dogging the car after he left?

The most common cause of limp mode from what I've gathered on the board is a faulty throttle position sensor (also happened to me). This might be triggered more from WOT operation (also happened to me), as might be the case when the new owner wanted to air things out with his new toy. Surprised there's no SES though.
Might be a fuel/filter issue- at higher fuel flow rates it can't deliver, leaning out the mix and triggering limp as a protection... but I'd think you'd see the CEL. Not sure though. And I am pretty sure you replaced that... Hmmm sucks...
A faulty TPS sensor can cause something that feels like limp mode without any codes....happened to me and a very common fault.
Mine was also caused by a day of extremely rough driving (mountain road with no one on it for 5 hours or so). I bet he was hot dogging it and the TPS went.

how much fuel is in the tank? I was hitting limp mode a few weeks ago when we had a heat wave and about 1/4 tank of gas, filled it up and issue gone. did not get ay ses lights as part of this.

The problem that I had with my car ended up to be the engine harmonics. I was comparing engine characteristics of my M5 with my 540i. Been told by BMW dealers and board members that was a big mistake. The fuel filter is brand new.
