Hi can anyone advise on a couple of faults with my ALT engine. I have found coolant leak at the back of the engine. Is this the thermostat and is it easy to replace?

Also the audi when driven on the motorway pulls to the left in normal driving conditions. I assume the tracking is out, but then took it to A_T-S and was told its a dealer job £100.00. What happened to the days of driving over a couple of pads and a spanner? Is there a cheaper option?

Any help on the matter is greatly appreciated

Thanks in advance
