i think you have not reconnected a multiplug somewhere on the engine thats all their is to it something you have touched is causing this problem and without a good look myself i honestly couldnt say what the problem is but its something stupid like either a bad connection in a multiplug or you have just forget to re-connect one

Hi there?
It sounds like the injectors are blocked. the reason i say this is because the bottom of the tank is full of durt and it must have got through when it was low in diesel.
You need to get the car scanned, if the code p1517 comes up then the injectors are block for sure.
Good luck.........

Hi there,

Code P1517 is specific to VW (P0 = generic code), so this code must be retrieved specifically from VW's DTC list.

This code relates to a malfunction in your Engine (MAIN) Control Relay circuit

Please note that I said "Circuit". This doesn't neccessarily mean the Control Relay itself is faulty (although this component will also need to be tested), but means you may need to test every component related to this circuit, and also other related circuts.

Cheers,

Main Relay Malfunction. This one could be tricky. Could be as simple as that main relay is bad. If it was it could cause an intermittent no start. It is located in your ECM box at the base of your windshield. I don't remember off the top of my head WHICH one in there it is. And there are 3 or 4 sometimes. So you will have to figure out which one. Take it out. There is a diagram on it. Test it according to the relay diagram. If it works then it might be something different. I have seen a lot of other problems (bad ground, bad battery, ignition switch, and more) cause that relay fault. So it can be tricky.

its built into the ECU
