So I'm driving along an A road at 70-ish today and the Glow Plug light starts flashing and I lose a lot of power. I limp to the nearest service station which was luckily only 1/2 mile away. Stopped the car and read the manual. It said I should have the car serviced immediatly.
Then I turned the car back on and no more problems. Weird.
The car has only done 10.5k, 170 tdi, and I plugged my blufin in and it did not give any fault code.
Any ideas any one? I don't even know what Glow Plugs are for once the car is moving?
