Audi A3 1.9 TDI 07. Engine cut out while driving no warning lights. Previous night had heavy wind and rain car was fine when parked. The next morning engine would not start, there was power to lights etc no warning lights. I left the car for 5-10 mins and the engine started, intermittent warning lights ABS, Power Steering(Yellow) and Brake Pads. Warnings cleared after a couple of seconds. Drove 30 miles to work with no problems, however after work half way home intermittent warning lights ABS, ESP, BP and PS(Yellow) again cleared after a few seconds continued home. Nearly home and engine stops while driving so pull over, there is still power to Lights etc but engine will not start no warning lights. Waited 5-10 mins engine stared no warning lights got home ok. Car now with Audi Yeovil, diagnosis was Power Steering Control Unit, however had call from Audi today and the fault is back after change of PSCU, more diagnostics will find out Monday. If you have any feed back as to problem/fault it would be greatly appreciated.
