Relay 109 was the problem for your exact symptoms on my 99.5 tdi. Temperatures rising and falling seem bring out the problem. The dealer tech determined I had a problem by probing the stop solenoid at the pump for voltage. No voltage=no run! Does your 98 A3 have the famous 109 as the newer ones do?
