Hi everyone, I'm currently verified but for some reason unable to post in the Car Repair forum. I was hoping to get some help ASAP before I pull my hair out and end up taking this beast into the Stealership.
Some context, I was driving to work last week....my Touareg started fine, drove fine, etc until about 5 mins into my drive it just lost all power and got a flashing check engine and a flashing glow plug light and it said "Workshop Fault"
I limped it home and scanned it, but I only scanned the 01 Engine module and came up with these codes...
I was reasonably certain it was the pressure sensor on the AdBlue pump that died so I replaced that but it did not solve the problem. After clearing all the codes in the engine module and they came back, I decided to do an AutoScan and this is the result.
So I think there is something SERIOUSLY wrong here and has to do with the electrical system. Electrical gremlins are not my area of expertise so I was hoping someone on here with more knowledge and experience could help me out. I'm really hoping to get to the bottom of this myself so I don't have to take it to the dealership and have them bend me over the counter...
I've never seen this many "Malfunction" codes on modules before. Could this be an indication of a wiring issue or perhaps the ECU dying? or a problem with the CAN system?

So I think there is something SERIOUSLY wrong here and has to do with the electrical system. Electrical gremlins are not my area of expertise so I was hoping someone on here with more knowledge and experience could help me out. I'm really hoping to get to the bottom of this myself so I don't have to take it to the dealership and have them bend me over the counter...
I've never seen this many "Malfunction" codes on modules before. Could this be an indication of a wiring issue or perhaps the ECU dying? or a problem with the CAN system?
