I’m here for the first time and must say, quite enthusiastic. Unfortunately, I’m also no less desperate. For some time my X25DT has become very hot under load. Especially under full throttle on the highway. FOH thinks that thermostat and cooler have to be changed. I did, also oil change in the automatic transmission. Unfortunately, after this very expensive history no improvement occurs. crankshaft and head have checked. You know the thermometer in the omega, can it be 100 degrees fast and as soon as I go off the gas the temperature drops again like a stone from the sky. Are the sensors in the cooler perhaps responsible? Well, I would be very pleased with the answers. MfG Björn Krause Omega X25DT, Bj 1996, 170,000Km, Automatik und Klimaautomatik, Leder ud Xenon.
