help, its packed up again

hello

help

the last time i drove this car it managed to do a massive 3 miles before it broke down and the starter motor went bandit and left me stranded

so i repaired it and left it alone,well alone after that

then i had the amusing idea of using it again LOL, mistake

first was the brake warning check pad light on

the fault was a broken terminal on the nsf caliper so the warning wire wasnt connected.

it managed 400 miles this time , a considerable improvement on the first breakdown but its in speshal needs mode again !

it feels like limp mode but no lights on, no boost and slow to do any thing

the tool im using is a maxi scan

the fault codes are

charge pressure control

positive deviation : p 1557

17965 - 035 01/01

kwp1281

i done the usual brief checks, as was dark,cannot see any vac pipes split, then erased the code and drove a few yards and its still in limp mode

has anyone had this issue and know of a remedy, is it a component or pipe work.... or....

is a 130 tdi a vnt turbo?

charge presure control and n75 sonoid valve , where are they fitted

regards
