Hello, I’ve been driving Opel again for a few months, an Astra 2.0 DI. Was 2 years of service founded unfaithful, a Golf 4 TDI with 90hp. I’m basically more satisfied now, only that the Astra needs instead of the 6 liters of golf nevertheless rather 7 liters. Since the temperatures are now 0 degrees, however, the engine will not be warm any more. I drive for my company 6 times a day 11 kilometers over land, and during the 9 to 11-minute rides the cooling temperature indicator does not jerk. The consumption is now also to 8 liters high although I drive neither highway or city, but only highway with 100km/h in 5th gear. Opel says everything normal. I say the spins, what I drive diesel if I need with 82 hp at 65km still 8 liters a day! The golf used to be also at -15 degrees after 6-7 km warm and did not consume more than 0.3 extra fuel just because outside are 0 degrees. Have changed thermostat -> no difference. 7000 km ago a new LLM came in. I am grateful for every info! Bo
