Matt S Posted February 26, 2009 Share Posted February 26, 2009 Hi all, I might be being paranoid, but I'm convinced something is getting more and more whistly (if that's a word...), especially at idle. It's not as bad as, but a bit like, when you hear Tdi-engined Disco's and Defenders. I have had a poke round under the bonnet and can't identify anything specific (no change there then ) but something sounds a bit odd. Still runs fine, good mpg, not too noisy on the go - but it doesn't sound like others I've heard and is a bit noisier than when I bought it... so is it normal or is something on it's way out? Any ideas before I end up taking it to someone who will relieve me of my hard-earned cash? It's a 2005 Td4 with 56000 miles and full service history.

Chris_944 Posted February 27, 2009 Share Posted February 27, 2009 Have you taken it toa specialist for them to have a listen. I have had a few turbo diesel cars and you can often here the turbo sppooling up, not usually anything to worry about though. If it is louder than usual could be a PITA to sort or it could be simple. Turbo goosed... doubtful at that mileage, vacuum pipes, possible.... When was the last time it had an oil change?? Quote Link to comment Share on other sites More sharing options...
white90 Posted February 27, 2009 Share Posted February 27, 2009 Check the intercooler hoses both split on ours check for loose clips etc Quote Link to comment Share on other sites More sharing options...
Matt S Posted March 16, 2009 Author Share Posted March 16, 2009 Thanks for the suggestions. In my usual way I have cured the issue by ignoring it and hoping it would go away, which it has... Put another 1000 or so miles on it and it is back to normal now. It mends itself!! Bless it... Quote Link to comment Share on other sites More sharing options...
neiltd590 Posted March 16, 2009 Share Posted March 16, 2009 worth checking hoses on front of engine, my wifes car had a hose almost rubbed through by the cross head screw under it, also turbo hose was leaking. Quote Link to comment Share on other sites More sharing options...
Jårv Posted March 17, 2009 Share Posted March 17, 2009 Hya, The whistle on my TD4 came from the hose you can see here wiv the red arrow: it had been cut by rubbing against the radiator ... and the air pushed out by the turbo made the whistle noise. Hope this is also your problem coz it's not to expensive to fix cheers B) Quote Link to comment Share on other sites More sharing options...
Matt S Posted May 16, 2009 Author Share Posted May 16, 2009 Thanks for the suggestions, sorry it's taken ages to reply I checked all the hoses, no splits, then found that the clip on the hose arrowed on Jarv's reply was a bit loose - needed about 3 turns of the screw, and the noise has gone away completely. Sounds like a different vehicle! Thanks again Matt Quote Link to comment Share on other sites More sharing options...
