Please which wiring colour goes to 1,2,34 my switch broken and could not figure out how to put it back, I got another socket but its different wiring colour from my car which is b5.5 here i attached with the socket and my car wiring.

Please 🙏 help still can't figure the right wire's my baby consumed heavy fuel 5ltr/10miles and may be it was due to this temperature sensor wiring

My diagram shows CTS pin connections:
1 blue/brown wire to cluster
2 brown/yellow wire to cluster
3 black wire to ECU T121/108
4 brown/grey wire to ECU T121/93

Check the wire colours at the ECU for 3 & 4
If you get 3 & 4 right, the other 2 wires are for 1 & 2, if you can't work out which way they go, it wouldn't matter if those 2 were reversed.

Thanks so much for your time and help I'll check with your diagram

@Tomvw, it works like a charm, thanks so much I really appreciate your help my temperature 🌡 is now reading normal, the only problem i notice is uneven rev it goes down and up don't know if it was because I drove it for little while without that temperature sensor wiring correctly

check all your vacuum hoses and check valves for breakage or tearing. That cloth hose in the pic is looking pretty tatty.

@Tomvw , thanks for your help again I checked for the leakage but could not figure it out, meanwhile i took my car for a trip of 350miles but to my surprise the car speed cannot go up to 100 miles hr press the turtre hard but only to find out it consumes all the fuel in less than 160miles , my question is what makes the engine to drop that power, normally i often drive on highway up to 120 miles per hr but nor way now.

There are many things that cause that problem.
Scan it with VCDS or other good VAG scanner, and post the codes.

Okay sir will scan it and post the codes here, I normally scan with obd 2 but only got turbocharger codes which i already know about it cos it has stopped working for a while

If the turbo is not working, you can expect to get poor performance and poor mileage.
I suggest you replace the turbo before doing anything else.
