Ok - investigations continue as leak was getting worse - plus still loosing coolant - think its coming from the water pump now!! Got the car up in the air, undertray off - lots of pinky sticky feeling fluid everywhere!! Just had timing belt and water pump done recently, so it's going back to them this afternoon! :-( just what I didn't need, I'm going on holiday in 2 weeks - plus I'd saved up some money to buy an immaculate mk2 golf GTi 8v - that's now on the rocks!!
