Limp mode when driving in traffic
We have a problem with our 2.4 (2010) Puma. When driving slowly in traffic the truck will go into limp mode. No engine warning light. Sometimes it clears quickly, other times it can take a few minutes to clear before she runs ok again.

Would a dirty ERG through up this fault ?

I would be grateful for others thoughts on the cause of the problem.

Mine had the following issue:
When driving into traffic after a long run, so warm engine, it would sometimes become unresponsive on the gas pedal. Car keeps running, but no power or revs (above idle). Quick fix was turn car off, and start again and wait until it happens again.

According the dealer they solved the issue (under 3 months warranty) by replacing the switches for the brake lights in the pedal area.


Edit: also no warning lights or error codes.

Thank you for your response, all good for a couple of months, but the same problem is back again.

Try to accurately measure the engine coolant temp when this happens. Mine was doing this but it was related to over heating. At about 112 deg c it would go into limp mode, then when it cooled it would go back to normal.

That would be my thought, too. It's a self-preservation measure in the event of overheating. It could be something like a faulty viscous fan, which would lead to overheating in the circumstances that you describe, or even a faulty cylinder head temperature sensor making it think that it's over heating. Darren
