Hello, I have the following problem. Today my Audi A4 B8 2.0 tdi was acting stupid. After a 5 minute drive, the car suddenly stopped and did not start again. I turned the key to start it but it didn't start it, just cranks for 3 times than it stops.
I took down the back seat, moveing the plug that goes to the diesel pump, after which it started.
When I got home, I started a scan with VCDS and it gave me this error: https://postimg.cc/TKMJt7hw
I searched on the internet and found something related to Fuel senders, how it should have some values ​​(in vcds it says the interval, I don't remember what it was) and I found that nothing appears for that fuel sender 2.
I think that the same values ​​should appear there for sender 2 as for the first, or at least one value, right?

Can I get away with it if I change the fuel pump completely?
I mention that after the car started (at 4:00 p.m.) at 5:00 p.m., approximately, I drove 80 km and nothing happened.
