Hi all
I recently purchased a 2005 X3 2.5 petrol automatic. 87k on the clock with a good service history. I noticed the heater wouldn't blow warm. There's oil in the coolant. Diagnosis has ruled out head gasket (thankfully), so the next assumption is the transmission oil leaking in. I've got a price for doing this which isn't too bad, but I was wondering, are there any other places/systems where the oil can get into the coolant?
Thanks all for reading
