turbo pressure too high?

hi all, after 500 miles of nice motoring limp mode is back with fault- turbo pressure too high. Tried to swop original file to ecu and back to defaped one, fault pops up after few miles again. Could it be pressure sensor on the top of intercooler? or something else? where should i start first? Many Thanks

A number of coupe HDi owners have had the same issue, (though I haven't). This problem was what let exboyracer to post the information I gave you the link to recently - the answer is in there and almost certainly relates to difficulty controlling the variable geometry turbo - can just be something else 'losing' the vacuum so there's not enough for the turbo control.

Was meant to be a joke, matey
