1.8tsi Turbo issues!

[Sampeett]

Hi everyone,

So from the beginning, I brought my mk3 1.8tsi petrol just over a year ago. Fast forward 3months I got the car remapped and they scanned the car and these two codes came up p029900 (under boost) & p256300 (turbo position sensor) appear. EPC light intermittent since I got the car. On heavy foot the car would pull fine then suddenly cut the power??

I went to a vag specialist who said the turbo was dead so I got a new turbo from a local garage fitted, two days later EPC light back on. Took it back and they send the turbo back and fitted a new one a few weeks later. Same problem!!! They have no idea what is wrong. It’s cost me a fortune with no ideas of what might be killing the turbos

Fast forward two months, now the car runs super rough and sinks of petrol, with a lean bank 1 code.

Anyone got any ideas? Thanks in advance.
