Hi there audi a4 b7 2.0 tdi 140 bhp..Starting to get lazy first turn of the key..spins over fast and fine then fires a bit rough but when starts it's fine.. the rest of the day runs like clockwork, no misfired no lack of power etc..once started once will start all day.
I have changed tandem pump , new Bosch glow plugs, new coolant sensor (TPS) and placed a non return valve online between filter and tandem pump , however still a pain to crank first thing....Any ideas? Thanks in advance
