Just had the Turbo replaced on my Puma (2009, 24,000 mls), due to the bearings running dry/failing. Also got the dealer to use the 3mm annealed copper gasket supplied by me instead of the LR OEM one. Symptoms where a high pitched squeal like a mild slipping fan belt. Sounded the same as when an exhaust manifold stud had snapped on a 200TDI. The noise only appeared once the engine was warm and the squealing coincided with boost demand. Put the Puma into the dealers twice with the normal no fault found answer from them. As it is a pain to keep dropping the Puma into the dealers I did a few tests including the fast idle test on IDS with no sensor readings out of the norm. Also performed a smoke test on the inlet and exhaust systems with no leaks found. Also used a boroscope and ran it around the exhaust manifold and turbo manifold incase the leak appeared when very hot, no soot marks, both still have that nice shade of rust. Next was the Accessory Drive Belt, as it sounded like a slipping belt, some of the paint was missing off the deflection pulley directly under the AC compressor but there was no damage to the drive belt to show slipping, no flattening of the belt grooves etc. Started the engine and had a listen as it was still hot, could hear a slight whistling from the area of the AC compressor, deflection pulley. Removed the cooling fan and accessory belt and started the engine (max of 3 mins as the coolant pump runs off the accessory belt), could still hear the whistle but it was coming from the turbo. Refitted the pulley belt and fan and then removed the turbo heat shield. Restarted the engine and using a stethoscope listened to the turbo and found it was to blame. Went back to the dealers and let them listen, result was a new turbo and no more whistle. I'm hoping that it was a manufacturing defect on the turbo and not an oil feed problem with the duratorq. Anyone else had issues with the Turbo on Pumas?

Sound's pretty unlucky Brian, there arn't too many cases of TDCi turbo failure showing up on the net. Turbotechnics (UK) would be the people to ask if turbo failure is a common problem. Did the dealer replace the oil feed pipe at the same time?
Cheers,

Tim,
they did change the oil feed pipe at the same time. I did ask them to do this prior to them fitting the new turbo, so not sure if they did it to placate me or if it is part of the replacement turbo?

Just had a call from the dealers to let me know that the new deflection pulley and accessory belt is now in stock, so when can I book my Puma in.
And here was me thinking that only the turbo was at fault?

hectic, sounds like quite a lot of work!

Hi Naks,
It only took a couple of hours to find the source of the noise, the longest part was trying to get the fan removal tools in place to remove the bloody thing. Plus I had porridge for breakfast so the pulley tensioner was a breeze to manhandle, Grrrr. In the UK the dealer is only paid to fix the problem by LR warranty so unless the problem is obvious they are unlikely to spend a lot of time fault finding which is a pain. I wish now that I had went looking for it earlier and saved myself 2 wasted trips but as it is under warranty I'm loathe to do this as the warranty is paid for in the new vehicle price.
