i have recently purchased an ex northern ireland police patrol car at auction, its a 2019 octavia 2.0 tdi estate, it drove thru the auction so i thought it was ok. when i went to collect it it started and drove but no turbo boost at all and iv a full dash of warning lights, abs, steering sensor, flashing glow plug light, tyre pressure light. car wont lock either. there has been a load of extra wireing removed from the car that was for computerised gadgets and lighting. the gateway module is hanging from the dash with 2 yellow wires about 3 inches long leading to nothing, they seem to be number 3 and 13 if im correct. iv lifted carpet in places and took off the inner sill covers but see nothing broken. im stumped on what to do. i have vcds and it wont connect to the car atall. any help would be well received
