hello there we have an Audi A4 06 2.0 TDI with a non start problem the vehicle was taking to audi where they diagnosed the problem to be down to a relay and replaced it. The car started up and went on its way it travelled aprox 50 miles and then cut out again and then was delivered to us. The codes we pulled from the ecu using Kts 650 are...
P1040 injector valve Group 1 circuit defective P2146 Injector Power Supply Bank 1 Open Circuit
we checked to the basics such as fuses and relay all seem to be ok and no water ingress in the fuse box. we then cleared the codes to see if that would make any difference and cleared however vehicle would not start and another code appeared...
P1517 main Relay Circuit Defective
we tried to find some wiring guides to carry out futher fault finding however bosch could not supply us with any as it is a siemans Simos PDD1 management so if anybody could help with either informing me where we could get a wiring diagram from or if they have had a similar problem?
