Mike1967, what is the wiring adapter for the 2 pin to 4 pin connections?! I don’t see that 4 pin plug-in on my 2010 Cooper S! I only
Have the two 2 pin connectors.

the 4 iin adaptor is because bmw/psa have updated the housing last year plugs in to your wiring direct fit,,, as so many were causing problem with plastic going brittle and leaking, or internal not controlling oil water temps and causing spiking when driven and get get hot etc, please dont be fouled with the cheap housing from china they are rubbish and cause more issues, have had a few when oil pressure light kept coming on after a good run, until we worked out that this was due to the housing allowing the engine to run over 109c and when you think oil is tested at 100c for its viscosity under heat and pressure it caused a lot of problems ie worst case is thin oil would wear crankshaft bearings and oil pumps out as a bi-product and people would repair these parts just for the engine to repeat its self, the latest genuine housing is 105c that makes a lot of difference and it should run correctly at that, below link for genuine one from a bmw and saab parts company,, after market parts on sensors and hosing link this is really a big NO NO we find on rolling road and mapping so many problems with people not knowing that a aftermarket part thats 1/4 or 1/2 the price is not going to have correct resistances needed to run a engine that has won a lot of awards for emissions and power and needs all this info to do so
