Understanding VAG-Com Error Codes Correctly ??

Hello

I read out the control unit today using VAG-COM. Because I'm having problems with my car.

The following error codes were found in the memory:

2 errors found:
01050 - Fuel quantity control valve (V117)
31-10 - Open circuit or short circuit to ground - Intermittent
01204 - Relay for Climatronic (J254)
30-10 - Open circuit or short circuit to power - Intermittent

I was able to delete the errors. However, I haven't yet made a test drive after deleting them. Could it be that the car is now running better?

And what do these errors mean?

Regarding error two, I can say that I don't have a Climatronic!

It would be great if someone could tell me what these errors mean or where I can find information about them.

Thank you and best regards, Mark

P.S. The car is a Golf III, manufactured in 1997, 1.9l engine, engine code: AAZ, Turbo Diesel ((not TDI !!!!!))

Hello:

1050: Filament monitoring, failure, open circuit or short circuit
1204: Engine temperature sensor, failure, open circuit or short circuit (engine always heats up to maximum)

P.S. I saw in your profile that you are an automotive mechanic. Which brands do you work with?
