This bulletin applies to 2012-2019 Audi A4 Quattro vehicles equipped with a 2.0L engine. The MIL may be on and low coolant level may be indicated.

Coolant marks around the coolant filler cap or at the coolant expansion tank may be evident. The pressure relief valve in the filler cap of the cooling system can give the impression that the valve is malfunctioning. Coolant marks around the filler cap or coolant expansion tank do not necessarily indicate that the cap is malfunctioning. Check the filler cap of the cooling system according to the ElsaPro. If the filler cap passes the test, do not replace the cap. Continue with fault finding.

Required parts and tools:

VAG1274B........cooling system tester
VAG1274/8......cooling system tester adapter
VAG1274/9......cooling system tester adapter
VAG1274/15....cooling system tester adapter
