Hi,
I have a 2.0 2012 B7 estate DSG which looses quite a bit of coolant (1 to 2 litres for around 20-30 miles) only when driving.
I’ve started the car and left it running for 1 hour or so, removed the covers and under tray but no sign of a leak. Loads of white smoke when I restart the car, when I top up the coolant larger air bubbles gurgle back through the coolant tank.
My understanding is the coolant is going through the system and being burnt hence the white smoke.
The car doesn’t overheat, obviously when the coolant light comes on I top it up.
My understanding is that This could be, a head gasket, the head itself or the egr cooler?
Before taking a plunge on the head, I’m looking to change the egr and cooler however is there a way I can test this to see if it the cooler?
Also, my part number of the egr cooler is 03L 131 512 BL, wha do the letters BL denote? I’ve seen some with DA on the end, are these newer versions which I could use?
TIA
