hi, i have jus bought a bora 1.9 tdi, 115 6 speed remapped to 150, x reg, and as soon as i got it the coolant light was coming on, i went to my local garage and he checked the obvious faults such as thermostat and water pump, and they were ok, he said the next thing will be the cylinder head, so i got a new cylinder head fitted and new gasket set, as the one on the car had already been skimmed so could not be done again. the new head and gasket is fitted and when i drove the car 10miles or so the exact same thing is happening, water is not circulating and is presurizing up, can anyone please help me on what else this can be???? all the pipes have been checked.
