I'll start with the obvious, is this dial on red or blue ?

I'll follow by asking what error codes you have and if the heater is getting hot?

I my memory is correct l322`s have an electric valve in the engine bay that lets the hot water through to the heater and they can stick.

Yeah there is a valve block that cause the issue on the L322, 15 min job to swop it out.

Is that only if it has an FBH?

Hi - yes have tried every possible permutation with the central vent (per your photo) and all the other temp switches, air con on /off and it still blows cold air
.Hi, thanks for the replies - could you tell me whereabouts is the valve block located?
Hi - there wasn’t an error code when it was checked at a garage

Depends what diagnostics they use, not all will read RR's.
Hi, yes it was working fine, the aircon was recharged and it hasn't worked since

Located on the right hand side of the engine but double check as you have the newer tdv8 engine ? I'm pretty sure the heater system is the same. It's a 15 min swop over remember the rubber hoses do bend so don't be afraid to move them for access.
