Just bought a 2014 audi a3 sline 1.8tfsi manual last month in a private sale and unfortunatly had a slight coolant leak, had to have the waterpump, thermostat, union and belt done at a cost of £675 at a local garage, does the price sound about right ? The thermostat was around £260 and waterpump was around £80 with vat added on both, which i think is very expensive, does this sound about the right price along with 4.5 hours labour ? Thanks
