Thanks so much for your time and help I'll check with your diagramMy 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.
check all your vacuum hoses and check valves for breakage or tearing. That cloth hose in the pic is looking pretty tatty.@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
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 whileThere are many things that cause that problem.
Scan it with VCDS or other good VAG scanner, and post the codes.
