Thanks for your reply. I have an E46 325i where the coolant tank failed. I drove it a similar distance to a mechanic. That engine is still running so I still have some hope for this E53. I will do a compression test as you suggest.
Would a head gasket leak or other loss of compression be detected by OBDII? So far I don’t have a check engine light.
Thanks.
