I always try to update my topics with any solution in case someone else comes by with the same problem. After the 90 degree plastic thermostat was replaced with no change it was removed and found to be cracked. On close inspection there was a gob of Radweld (oh dear) on the seat so that when the new thermostat was tightened down it distorted then cracked. Cleaned up, cooling system flushed, all ok for now until the reason for the Radweld crops up. Thanks to all responders to this problem.

Hello all, thanks for all your input, I'm easily overwhelmed by technical details so can I just check that it might still be the DSG thermostat or might that be one of the two replaced so far? To be fair to the garage mechanic he might be struggling but he is honest as the day is long, he prefers Mini 1275s and Mk1 Escorts, I've told him he should concentrate on Classics and charge double.

Thanks for the answers, I'll try to add a few details. The latest test drive was thirty miles in 8 degrees C, max water temp 62, put the heater on then it dropped to the stop, max oil temp 65. I've had a mooch about, perhaps the mechanic had changed the oil thermostat as well, I'll ask him tomorrow. Would you be able to tell me what a CTS is ?

I forgot to mention there is no engine management light or fault messages.

Hello, my vRS coolant temperature is low, it barely reaches 60 degrees on a test run. Both thermostats have been replaced but it is still the same. The local mechanic wants to change the water pump next but wouldn't a failure of that mean running too hot ? The coolant temp gauge seems accurate because the oil temp only reaches 60 degrees as well. I am only driving the car at the moment for test drives after garage work. I would be grateful for any advice, thanks.
