TURBO BLOWN TWICE IN 11 MONHTS

2008 Mazda 5 • 96,000 miles

My turbo blew last September taking with it the gasket and injector. I was charged £2000 for it all to be done at a independent garage. We were driving on the motorway yesterday at a steady 75mph, no acceleration involved and the revs went upto 3000 I thought maybe I just needed to change gear and pushed it into neutral, the revs went over 6000 and white smoke was pouring out of the engine. The only way I could get the smoke and revs to stop was to pull over and switch off the engine.
I have read a lot of articles that say this would be down to poor workmanship and the garage should be liable to repair the work.
Is this the case? Is there anything else that would have caused the turbo to go again?

Last september? If it is a wrokmanship issue, it would have been an issue immediately. Why are you blaming the shop?

Are you current on all your services with the turbo? Oil clean and changed at correct intervals? Thats one of the main reasons for premature failure, not 1 year ago installations.

Have someone remove and inspect the turbo for the reason it failed. Low oil level is a common issue as well. Supply tube to the unit must be clean and sufficient oil pressure as well.

White smoke is an indication of burning coolant from a head gasket. Have that checked to confirm. When a turbo failes, it will blow blue smoke and burn oil.

I had a service in June before I went on holiday! All filters etc were changed, from what I can understand the pipes connected to the turbo should have been changed and if they weren't this could be the issue, last time it blew I didn't have blue smoke, just white

Ok, I serive in a year? How many miles? If you dont change the oil every 3-4 k miles, you are damaging the system from lack of maintenance.

Like I said, take it to someone to verify the failure and remove the turbo and inspect it and the lines. The lines dont always need to be replaced but they need to be checked. You have a lot of time here from the service. Have it confirmed to be sure.
