hi thanks 2016 t6 76000 went 30000 between services. first turbo went not long after i had service and cam belt ect changed. Garage said the turbo fan shaft was rattling inside the turbo. So i ordered new turbo with all pipes, gaskets and even the oil from vw van centre birmingham. and my garage fitted new turbo had the dpf taken off and flused clean and tested for flow and re fitted that. Ran for about 80 miles no noise ran so smooth no warning lights just ran great and then the next day ran for 2 miles and the engine management light came on and i heard a loud pop, then lose of power and rolled the 2 miles home with little power. The garage that fitted the turbo came out and had a look and said turbo faulty and when the took the filter box and pipe of that goes to the turbo there was a little nut loose in the pipe which had come off the shaft with the fans on in turbo.
Waited 3 weeks with it on the drive had it low loaded so not to run the engine back to vw birmingham who said they had to inspect the fitting of the turbo befor they would replace as i had only had it a few weeks.
They phoned on friday just gone and said yes it had been fitted ok even said good job by who ever fitted it but need to speak with warranty guy on monday to get it ordered. And then today after i had waited til after lunch i phone them and they said they would not replace unless i can prove thta the oil high presure stage had been activated.
I phone my garage and they had never heard of this, i then checked with several vw repair guys and garages and no one had ever heard of this when replacing a turbo. Vw then said its in there repair manual and thats why the turbo failed and i will have yo buy anew turbo and bits which would cost me another £1400.
At no time when i bought the parts did anyone say the turbo needs to be fitted in a certain way or if certain things are not done then this will happen, as my garage said and so did many more the nut coming off is the issue and the turbo is faulty and should be replaced. i attache photo of turbo also email vw sent showing small print in there repair manual. which also states this pressure stage is not always available to set. Thanks
