All,

Sudden and strange problem with my 170JTDM veloce. Just been serviced, MOT'd and some warranty work done (front drop links and gear position sensor).

Twice in the last 2000 miles an odd thing has happened. While in D mode, the turbo boost is limited to 50% (according to boost gauge) and it wont rev past 3000rpm. This leads to a shocking loss of power and caused a pretty dangerous situation as I pulled out to overtake a lorry.

There are no warning lights, temp is OK and the problem is rectified by turning off and on again!

Any thoughts?

Does it only happen D mode? Take back to dealer and have them check your software.

It also sounds like it was in limp home mode but it clearly wasnt because you were in D... Definately take it into the dealers there could be a error code somewhere that might explain it.
