Moin, had to fight this morning (-12 degrees) with considerable cold start problems with my Omega 2.5 td (Bj 99, 223000 km). On the one hand, the starter always jumped in for 3-4 seconds with each start attempt and then continue turning without moving the engine. Question 1: Is this normal or can I assume that the magnetic switch is broken?? The engine starts at temperatures above zero degrees easily. Question 2: Can I rule out compression deficiency and the error rather in defective glow Hkerzen or limit water in the diesel filter?? By the way: The air mass meter is defective Thanks for your answers Rexi
