I've had this error today, we were heading south on the A1 towing a caravan and doing 60'ish uphill on cruise control. I accelerated to overtake a wagon and nothing happened! I dropped to Drive, into manual mode, geared down and it still wouldn't budge so I floored it but the engine revs topped out at 3k.
The speed kept dropping until we were doing about 40 on the flat in limp mode so I pulled into services and parked up. My Carista wouldn't work, as the 30-day trial had expired and it wouldn't connect to iTunes so I could purchase it

I gave up eventually and headed off home to find all was fine again, no flashing glow plug light and no limp mode so fingers crossed it was just a glitch.
By the way, the oil temp hit 115 about 20 minutes before, could this have been anything to do with it?
