Hi all guys : I have recently bought 2 Rover 75's : 1 2003 Berline (Gen 1) & 1 2004 Tourer (Gen 2). 1st is a 2.0 CDT, 2nd a 2.0 CDTi

Some minor things on the beeline, but some rather weird issues on the Tourer, I'l explain :

1) outside temperature shows constant 37 degrees Celsius (global warming isn't that powerful, so I guess ambient temperature sensor (in the bumper) broken ?

2) engine doesn't get warm : even after 20 min's of driving, it still shows as cold inside, hardly past the blue dot. Blowers inside blow COLD air.

So I placed an inline thermostat (the R5 type). Now, it's still the same, when I turn OFF the airco it gets up to 1st mark, not to 9 o'clock mark, after 30 minutes only ! Big coolant tube at the inline thermostat feels hand-warm only.

I checked the full codes, it throws me FC 21 & FC 22.

When I turn on the airco, temperature drops again, and blows COLD air.

Any ideas guys ?
