Default vcds scan after service

My S8 was serviced by Lecab, Audi Karlstad the 31st last month.
I made it home, with the engine oil lamp on and the rpm needle was dead.

Today I ran a scan with vcds to try see what it would tell me.
The engine oil lamp and the rpm needle worked today, so I took it for a drive. About 400m from my home the car made a few engine brakes, or I think it did. Then it died. So now the car is on it's way back to Lecab with roadside assistance.

Here is my auto scan before the road failure.

Wow Its interesting that most of the modules simply say 'electrical malfunction' rather than voltage too high or low. That might be a prefacelift thing though. ME7 in the facelifts is a little more verbose in its error messages.

I think the first things I would be looking at are the battery, alternator, and earth connections, particularly the earth strap from engine to body. Then probably monitor the battery voltage with a multimeter to see what its doing.

Some of those codes like the immobiliser and alarm are pretty normal. The open or short codes are likely caused by whatever is also triggering the electrical malfunction codes, in modules which aren't smart enough to detect a voltage issue.

Thank you for the comment MJ. I haven't even considered the battery, and earth connections.
The mechanic claimed that the wiring to the oil pressure sensor is damaged. Which they have in part replaced at an earlier occasion (about half a year ago).

Is it normal that one can do a full auto scan, but other specific scans throw timeout errors?
I didn't get the engine scans to respond. Same with the Immobiliser even if I have scanned that part earlier.
The automatic box responded when I tested that.

The oil pressure sensor wouldn't cause all those errors, even if it shorted out. I think there is probably something else going on too.

Its odd that you can scan the engine on an auto-scan but not on its own. I wouldn't expect that. It could be a symptom of a general electrical problem though.

I got an answer from Audi. The fuel pump 4D0298087B is broken
Repair cost 18000 SEK.

I asked them for an offer to fix the fuel pump, whatever the electrical fault is to the oil pressure sensor and fix that too.
And for an offer to change the belt cam with water pump etc.

This is going to make a dent in my bank account. But I still wish to repair this car.

I truly wish I lived not to far off from you MJ. I'd feel a lot better dropping the car off in your capable hands

Schedule a two week holiday in the UK.
Drive to MJ's and leave the car with her.
Hire a car and have a great time touring UK.
The total cost will probably be less than the stealers, and you will have had a holiday as well.

I don't know what 18000 SEK is but it sounds like a lot of Fjallraven jackets.

This the pump you need LINKY, It can be fitted into your pump unit and can be done at home with basic tools, and you can get off your face on petrol fumes

If that 18000 is just for the (updated) pump unit then the quote for the cam belt will be horrendous.

18000 Swedish Krona? According to google that's a shade over £1600 GBP today.

That sounds pricey given the ebay part is £120!

Yeah it's about double what Audi want here. The pump is only 120 ish but the pump unit is 800, Audi discontinued the pump unit as it has a mod and the pump is not available from them, so if you want it from Audi you have to buy the whole modded pump unit.

That is correct, just over £1600 for the pump with fault checking? and replacement.

Is that really the part Dezzy? The part number doesn't check. 4D0298087B

But from what I could find, the part is expensive.

And I am not about to take the fuel tank apart just to do the job myself. I don't have a nice garage, and it's cold and icy outdoors
