Recently had the timing belt, water pump, all valves and rocker arms, fuel filter, oil filter, air filter changed on my 2006 Audi A3 8P 2.0 TDI 140.
I've had it back for two days now and it struggles to start when cold. Splutters a little when started warm but generally starts pretty quick. Any idea why?
My initial thoughts are glow plugs or starter motor…
