Volkswagen Crafter 2.0 TDI

It is a 16 Seater Volkswagen Crafter Van with leather interior. I recently replaced the whole turbocharger, EGR Intercooler, EGR Valves and Vacuum Valves together with Oil Filter Housing however I recently encountered that the computer box is faulty. I dont have the necessary cash to fix it any further since I ran out of business
