I have just had my car seviced and all seems ok apart from the increased noise from the air con unit and other issues mentioned later. When I asked I was told that this could be the compressor. Has anyone had this problem and is it expensive to replace? My focus is a 2005 plate and has done almost 80k miles. The other ongoing problem is it has slight rattling sound still on start up and have been asvised that this may be the variators which can only be replaced at the dealer at great expense no doubt and also the petrol engine sounds like a diesel and again have been advised that this could be the variators and/or the cambelt timing sensors. These issues make the car very sluggish when driving uphils/ overtaking akin to towing a barge and on minor hills slowing down and having to use 1st gear on some instances!
Getting back to the first point are air con compressors expesive to replace?
