Hello everyone,
Firstly excuse my ignorance- not sure that im posting this question in the correct area.
Anyway here goes.

Alfa Guilietta 2.0 diesel JDTM2
2011 on 49000miles
Above error code appeared in the week limiting all sport modes and car will not rev over 4000ish revs.
Ive reset the code using a obd2 reader and started the car up immediaey putting the car into dynamic mode and using the menu to check the turbo boost level. This was not showing any level briefly before the car went back into normal mode displaying check engine, auto stop/start button illuminated.
Scanner said something about Circuit A boost controller?!?

Can anybody please point me in the right direction as to what sensor could be playing up(assuming it is a sensor and not the turbo). Checked all vacuum pipes and turbo is spinning.
Appreciate this and awaiting a response as I dont want to keep driving the car in this limp state.
Regards
Mat:confused:
