Hi guys. I have interesting problem with my gen 1 Haldex. 4x4 is working all the time, but when car is cold then its showing fault and ESP light is on (01324- Control Module for All Wheel Drive (J492) and 01312 - Powertrain Data Buss 37-10- Faulty- Intermittent)). After i drive at least 25 km and restart the car ,both faults are gone (No faults on VCDS). Also in summer time, no problems at all, no faults , but at the autumn , problems start coming up. Maybe someone have similar problems and have some solution , tips, where to start ,what to check? Thanks.
