Guys our MK7 GTI done 100kms has signs of oil in the coolant expansion tank.
Is this most likely to be the oil cooler unit?
I was planning on flushing the system but no point going too far if the oil keeps coming through.
Car is due thermostat and waterpump replacement as these are common failure on mk7 and waterpump shows signs of a slight leak so thinking may as well replace the oil cooler while its all apart.
Unlikely to be head gasket on these motors.
