Turbo wont boost. Things to check?
Hi all. I was driving to football this morning and as i started to boost in 3rd gear all of a sudden my boost cut out and dump valve released all pressure just as if i let off throttle.
No smoke at all and turbo wont go over 0bar of boost. Had a good look under bonnet and cant spot anything obvious.
Im not really a mechanic by any stretch but i know the basics.
Can anyone help we things to check please?
All help appreciated
Thanks

I guess the first thing to check for is any leaks on the inlet side. If you've done that, you might want to manually check the turbo spindle. If you take off the inlet side of the pipework that goes to the turbo, you should be able to see/ feel the impeller. There shouldn't be any significant play in the shaft and it should rotate smoothly. If the bearing has gone, it should be pretty obvious (mine had around 3mm of play and you could feel resistance when turning it).
