Evening all, I wrote a post a couple of weeks ago regarding a coolant leak on my 1.8T. I've now noticed that the temp gauge which has always sat at 90 when warm, now sits between 80 and 90. The car is also very spluttery in the morning when cold and is as normal when warmed up. Coudl all of these be linked.? The car was checked for external leaks and nothing was found. Could a faulty thermostat use coolant.? I'd much rather deal with a faulty stat then a head gasket. I'm seriously considering handing the car into the scrappage scheme but it would be a waste in my opinion. :-( Thanks in advance, Rob.
