Hi All,

Picked up my 08 Cooper S yesterday.

I've used my Carly for BMW App and OBDII to see if there were any error codes. There is one that will not reset in the Engine/Motor group:

DFES DTCM.DFC DSACmin C - refrigerant pressure sensor

Any body know what this code is and what I need to do to fix it?

Thanks.

P.S. Also planing on getting the walnut blast inlet clean done.

Thats the aircon pressure sensor , could be just no refrigerant or faulty sensor . should have one if it's sensor or hose or indeed air con condenser etc .G

As regards sorting it the 1st thing to do is have the aircon system checked for leaks , most air con machines do this anyway the system in vacuemed and left for a period of time and if it looses vacuum you go looking for a leak , if not just let the machine refill with R134A. again we can do this if that helps .

Thats unusual for an 08 S , are you sure ? it may have 'climate' control , if you like send me the last 7 digits of the vin number by pm and I can see the spec . reg no will also do . or post a pic of the heater controls . I don't think I ever saw an 08 S without either air con or Climate . G

Now that's a first ,no air-con , it was built on Jan 30th 2008 , no idea what your fault codes are could be phantom codes , a check with BMW /MINI diagnostics should be more detailed and get to the cause . G
