I would like to fit a Oil pressure gauge to my 2012 L320 3.0sdv
Any advice appreciated.

Don’t bother would be my advice.

Once it drops, engine is gone. Monitoring it will just increase anxiety and won’t prevent any of the issues.

I'll find out within a week if a new pump fixes my 4.4 TDV8's low pressure. I didn't like the suggestion to ignore it and wait for the knock from a piston hitting the head before doing anything about it.

Fitting a pressure transducer to a 3.0 TDV6 is easy as the switch for the light is at the top front of the engine.

Yours would IMO be a different case Graeme,

You’re dealing with an engine known for low pressures and gone ahead and sorted it.

In the OPs use case - checking oil pressure during a service should suffice as the DV6s aren’t known for the same issues.

The TDV8/SDV8 has exactly the same low oil pressure as the TDV6/SDV6 but at least the TDV6/SDV6 is easy to check. My engine is giving no indication that warm pressure is very low and I have no idea for how long it has been low, so I wonder how many other V6 and V8s also have very low pressure.

And seems with the 8 speeds the ability to cruise at very low RPM can take it to minimal oil pressure.
