Can anyone tell me where the ac pressure sensor switch is and how to access it on my 05 x-type? My compressor works system is charged nothing but hot air. Any ideas?

 

You need to remove the right side wheel arch covering. The transducer is located between the fender and the sidewall of the engine compartment.
It can be unplugged and removed with out draining the system.

 

has anybody fitted a rear wheel speed sensor i have the abs light on and the brakes have started to groan and make funny noises

 

The speed sensor is held on with on bolt and easily changed. It doesn't sound like that is your problem You need to raise the rear tire off the ground and grip it at the top and bottom and try to rock it back and forth. If it rocks at all the wheel bearing is toast. The sensor reads the wheel bearing to determine wheel speed.

 

Thanx found it glut a spare used one from the salvage yard just incase.
