My October 2013 SEAT Leon 1.8TSi petrol DSG FR 5-Door has been displaying a permanent steady (not flashing) amber engine fault icon for the last week, with no indication of the type of fault in the status display, and no apparent symptoms when driving. The same fault indication occurred for about a week about 4 months ago, but then cleared by itself, so I didn't bother to get it investigated until the fault reappeared last week. My local SEAT dealer checked this out today, and reported the following "Fault stored with coolant regulator and signs of coolant leaking around the regulator unit - approx. £675 to fit new regulator."
Before I book the car in to the dealer for repair, does anyone know exactly what this unit is and why it is apparently going to be so expensive to replace? The car has only done a very low 20,100 miles since new, and has always been serviced on time by each year by SEAT dealers, so I'm very surprised that this has occurred at such low mileage.
