This may be normal, but I'm new to Mercedes diesels and have just purchshed a C320 CDI. Before I start the car I wait for the glow plug light to go out, then start the engine. However, after about 30 seconds the glow plug light comes back on and stays on for about 2 mins while i'm driving then goes out. The car is under warranty and I have seen on the forum that glow plugs can be a problem so would like to know if this is Ok?
