Hi,
I'm trying to replace the heater control valve on my S3. It has a 200TDi conversion, and there is a threaded hexagonal spacer between the engine and the valve. Unfortunately this is not coming off the old valve despite significant persuasion. Does anyone know whether this spacer is a LR part? I'm assuming it's a fix to mate the S3 valve to the TDi, as I can't find it in the manuals I've found online.
Here is the old valve with the spacer:
This is where it goes into the engine:
If anyone knows where I can order a suitable alternate, that would be fantastic. It's 40mm, but 45mm or even 50mm would be better. He control valve has a 15mm threaded section, and the spacer has a 10mm threaded male section. I'm not sure of the male and female diameters but I'd hazard a guess at them being M16.
Thanks
Dan
