A question for Avant maybe or 659, who is the fountain of all knowledge on VW PD engines.
I have an Audi A3 2003 1.9 TDi which I assume is fitted with the Bosch injectors.
But I would dearly like to get hold of an A4 Avant 1.9 TDI around the same age.
The question is how can i find out if it is fitted with the reliable Bosch injectors or the later piezo siemens ones which cause so much grief ?
