Manxman Posted September 4, 2007 Report Posted September 4, 2007 When switching off the engine ( 1.9 tdi ) I hear a noise like a dry bearing wirring for a few seconds. If I increase the revs to 1500 rpm before switching off then the noise is louder and lasts longer.. Could it be related to a wastegate problem? . There is no loss in overall power .. I might add that this has come about since having the Ford dealer replace the timing belt last week .. Do any vac pipes have to be removed when changing the timing belt? Any help much appreciated.

chromedome Posted September 4, 2007 Report Posted September 4, 2007 Have you tried it with your foot on the clutch. I'm wondering if it could be the clutch thrust bearing. Of course if it's a auto please disregard. If you put you vehicle details in your signature, people will have a better idea how to help. Quote
Manxman Posted September 4, 2007 Author Report Posted September 4, 2007 Sorry. It is a manual 2001 1.9 tdi.I just disconnected the hose on the engine side of the MAF and discovered the noise when switching off, comes out of the hose. So, it appears to be in the turbo area. Could a sticking wastegate be the problem? Quote
insider Posted September 5, 2007 Report Posted September 5, 2007 There isn't a wastegate because you have a variable nozzle turbocharger and it's a diesel (no throttle valve). Personally, I would return it to the Dealer and complain since it only appeared after they worked on it. Quote
isk Posted June 30, 2008 Report Posted June 30, 2008 Hi Manxman, just wondering if you have managed to sort it out - I've got similar noise coming from the turbo area and would love to know what's causing it. Quote
gregers Posted June 30, 2008 Report Posted June 30, 2008 isnt this the run on pump thingy majig????? Quote
isk Posted June 30, 2008 Report Posted June 30, 2008 hmm, gregers could you possibly elaborate on the subject a little bit? thanks Quote
gregers Posted June 30, 2008 Report Posted June 30, 2008 http://www.fordgalaxy.org.uk/ford/index.ph...amp;#entry97935 or maybe im barking up the wrong tree................or im just barking. Quote
isk Posted June 30, 2008 Report Posted June 30, 2008 no, it's not that :o - the sound is definitely turbo related Quote
sepulchrave Posted July 1, 2008 Report Posted July 1, 2008 It sounds like the turbo is spinning down and you may have an air leak somewhere which is amplifying the noise. Check all the hose connections. Quote
Smilge Posted July 1, 2008 Report Posted July 1, 2008 Does the "whirring" decrease in pitch when you turn the engine off? If so then you are looking at turbo bearings. If it doesn't then I would suggest the run on pump if yours has one. Check the hose connections as Sepulchrave suggests particularly the Intercooler to turbo hoses. Quote
geoffc Posted July 1, 2008 Report Posted July 1, 2008 I too have a similar turbo related noise! I have noticed that I heard a slight "plop" sound just as the turbo was nearly stopped.....sounded like a valve closing, then the turbo noise abruptly stopped too. Has anyone had any success with a fix? Quote
Alick Posted July 9, 2008 Report Posted July 9, 2008 i have the same problem i followed the vacum pipe from my air box and found two boxes were a few vacum pipes plug too with electrical wiring too and there is a feed off to acuator and turbo can any one tell what these two boxes are because that is were my noise is coming from so i know what im ordering Quote
