My car is making a noise it shouldn't be, it's the 1.7 cdti 2011, when just ticking over its noisey like doesn't really sound like a normal diesel, press the clutch and it sounds fine (as it should in my opinion) lift the clutch and it's noisey again, my mate says input shaft bearings maybe or thrust bearing, it's still reasonably low mileage

Hello,

I had my car at service and they told me I had to change my turbo. Is this a common problem? 

The fault codes was P0299 and P003A. 

Is there any knows issues with the turbo on this car? It has only gone 75000 km / 46000 miles

Opel astra J, 2010, 1.3 CDTI. 

Kind regards
