canon can Posted April 4, 2009 Share Posted April 4, 2009 Hi all, I have a funny noise when I turn on the air con on my 2000 TD4. It is a growl and is louder and more noticable as I deaccelerate. Can any one point me in the right area of the problem please? Canon can (and will) Quote Link to comment Share on other sites More sharing options...
rustymark Posted April 4, 2009 Share Posted April 4, 2009 Hi!! Strange this! Had this noise recently. Have you had the under engine panel off?? You might find that its the black plastic flap from this which has popped inward and is fouling the air con compressor pulley. If you take off the underpanel you'll see score marks on the plastic. I had allsorts of dread and doom in my mind but was simple fix! Why it makes more noise on decelleration I have no idea! Mark Quote Link to comment Share on other sites More sharing options...

Blippie Posted April 9, 2009 Share Posted April 9, 2009 Yep, we had this on our TD4 when the black plastic splashguard inside the offside front wheel arch was pushed back towards the engine bay by a bit of deep (and probably quick, knowing Mrs Blip) fording. The water had pushed the bottom of the plastic in-and-over the sumpguard. Easily diagnosed because the funny noise nly occure when the heater was on windscreen or windscreen-and-feet setting, so we started looking at the aircon. One pull on the plastic and normal service was restored. Cheers Blippie Quote Link to comment Share on other sites More sharing options...
