Hello

there's a tank pump that isn't actually a lift pump as it forces fuel from one side to the other of the tank , if this is faulty then you'll have triuble picking up all the fuel and the car may struggle to start on hills

So thats one aspect but also replace the fuel filter before doing anything else as these only need to clog up a little to stall the pump

Hi Matt , thanks for your response . As l'm a petrol head and like DIYS

so happens and this time , l would like to share my experience . Some models Audi have not primary fuel pump - like my one - it's all in one in

injection pump , trouble was - as ECU had faulty what l saw when

glow plugs light start flashing 20 sec. after turning ignition on . All needed is discharge the faulty , then plug light stop flashing and that's

all , it's not clear how the ECU fault came but it was false .
