Hello,
I dont have a A2 but have a Polo 6n2 1.4Tdi AMF, and have been have same problems, specialy the first start of the day or if the car sits when i go to work and get off after 8,9 hours.
The problem is that when o try to start if the glow plug light doesnt go off after +/- 1sec. and it goes out after a few secs. the cranking somes "heavie" or "low batery" when it starts the engine revs by it self to 1800/2000rpm, it doesnt happen every time by when it happens its annoying.
In VCDS the error recorded reports to the coolant sensor.
I already have replaced:
Coolant temperature twice (one with a non original but good make and recently with the original from VW)
Battery (VARTA)
Glow Plugs (Bosch)
Also have replaced that dont have nothing do with it.(i think)
Oil Pump chain and all of the sprockets (OEM)
Timming belt + water pump (INA)
Turbo rebuild
New alternator (Bosch)
Power Steering pump (Bosch)
The car after it starts the idle sits higher then when it doesnt happen.
Can it be the injectors?
Can i check in VCDS?
Any other idea? please
