Question about 2002 Volkswagen Jetta TDI
Car surges while in gear at ide, clears up under power.
already done fuel temp sencer changed, intake cleaned
Is this model common rail or does it have an injector pump,injector pump has a built in lift pump and if this is weak then the transfer pressure is low which is causing scavanging.if this is the case then fitting an in line non return valve in the fuel in line can help,but more often than not fitting a low pressure in line fuel pump is a cheaper solution than an injector pump overhaul
