Basically it's -2 here, got into the car, got onto a straight and floored it, lost half of the power, first time this ever happened and I knew it was Limp Mode. I got a bit scared so I pulled over and turned it on and off, it was fine then. I was still worrying so I did a little test, left the car parked for a few hours while I slept, got into it without warming it, same straight road, floored it and then Limp Mode again at -1.5. When I thought it was just because its cold, I drove around and let the car warm up a bit, until the temp needle reached 90 I think, got onto a longer straight with it warmed up and floored it like crazy in all gears, no Limp Mode on several tests. So am I okay? It is actually the cold weather? I have 2.0 TDI.
