Rugged running of the engine in cold condition V40 TD Bj.1997 Hello dear forum reader! (Volvo V40 Diesel Bj. 1997) Maybe someone can help me with my above mentioned problem. If I start the engine in cold condition, then it starts bad first and it runs very restless. This takes about 2-3 minutes or if I have driven about 500-1000m. This problem is as said only in cold condition available. I have installed new glow candles already, unfortunately without success. I gave already once already someone has the tip to check the guide. It serves 2×2 glow candles with a double relay. Where can I find this relay? Can I check it myself (with a standard measuring device) or should I drive to a Volvo workshop? For your help I would like to thank Josef
