Hi all, The local Audi dealership had my car last Thursday as the air con wasn't working. They replaced the compressor and I thought all was good, nice cool air. Driving home yesterday and all of a sudden DIS starts showing COOLANT! Fortunately I was 3 miles from home, the temp guage was normal so I got home. I opened the bonnet and hey presto, no coolant except for the stuff all over my engine bay!!! The nice RAC chap arrived and had a look and found a hose that had not been clipped back in its holder, which when the fan started to go it cut big holes in the hose, no coolant! Anyway after having to put some pressure on the dealership they finally provided me with a car!! Anyway the question, what sort of damage could have been done to my engine (diesel)??? any thoughts? sorry for the long rambling message Chappers.
