ESP light and Tyre pressure monitoring light is always on

[hippyhippy]

Short background story:

I accidentally put some regular petrol in the 09 diesel tig. i didnt turn on the car and had the car towed to the closest service shop. I left the car there overnight as they said they will drain and clean the system and car should be alright.
Next day my wife picks up the car and advises that the 2 lights wont turn off.

I checked what they did and they said that they took the rear seats off to access the feul tank to drain it and put in a new filter. They didnt do anything else apparently.

They check the VCDS and this is what it is showing as faults:

Address 3 - ABS brakes - malfunction - 1 fault found - Control Module for AWD J492
Addresss 19 - CAN gateway - status malfunction
Address 22 - AWD Cannot be reached
Address 25 - Immobilizer malfunction
Address 46 - Centreal Conv malfunction

Its possible that maybe some of these error could have been existing before this incident. i do now know as i dont have a vagcom myself. The other things which have happened not long ago was the air con compressor was replaced by VW. however after they had replaced the compressor the car did not have these lights on. Anyone have any ideas?

My thoughts are can the towing guy somehow damaged something? he wrapped cable on top of the tires front to back over the front wheels but the back wheels he put the cable around the wheel, Could that have damaged something?

Did the service guys somehow disconnect some cables and not plug it back together to get to the feul tanks?

Also, my car is currently showing signs of a battery thats going out, it doesnt last long if you leave the lights on for maybe 10 minutes, the car wont start and requires a jump start.

I have checked fuses relating to ESP and they all look good however i didnt actually test them with a multimeter.

Any ideas?

Low battery voltage is my guess.

You really need to know what the actual fault codes are to have some idea of what's going on. The list you have provided just shows which systems have logged faults.

VCDS should show the mileage when the fault occurred. This will clear up the question, whether the faults were pre existing or not.

[Umai Naa!!]

Yes, that as well.

Turns out they didn't plug the cable to the unit properly. All good now.
