Hi all,
I bought my A2 1.2 tdi (2002, 180k km) few months ago. It had broken hydraulic pump
which was changed (almost no brakes and turbo stopped randomly) and new fuel filter (genuine Audi part)
was changed. Oil and other filters was changed.
Now there is only starting problem left. Start/Stop doesn't work. It stops, but very rarely
starts so I have to drive with eco off. It tries to start a little, but then gives up.
Normal starting (cold engine) works by turning key for about 10sec or it fires and stops
and I have to start again. When it starts to run it works ok.
When engine is warm and stopped for half an hour starting may take tens of tries or it is
impossible to start. It fires and stops or doesn't even fire.
Quick stop and start (within few minutes) works as well as with cold engine.
Two times engine has stopped from idle after running motorway for 15km. Then I was
using eco mode. It took long time to start again after these shutdowns.
My mechanic (who knows VAG cars quite well) says that there is a leak in fuel system, but as
it was not fuel filter and lines look ok it must be injectors. He says that usually new injector seals
wont fix the problem. His/their experience is that changing seals usually makes things worse
because bores are/get loose on this engine type. They haven't opened engine yet.
I'd like to get second opinion on this and ideas what else could be causing this problem with starting.
What are my chances to get a working car by injector seals change?
Otherwise car feels good. There is no error codes from ECU. Consumption was 3.1l/100km on my
daily trip to work and back. Now consumption is almost 5l/100km because weather (-20 to -27°C)
and I haven't used eco mode after those stops from idle.
