1. Remove oil pressure transmitter and screw oil pressure tester VW 1342 together with M 10 x 1 adapter, Part No. 999.105.013.02, and M 10 x 1/M 18 x 1.5 adapter, Part No.901.101.175.01, in its place in the oil/water cooler housing.









2. Run engine to operating temperature (80° C oil temperature), checking the temperature with, for example, an oil temperature tester (Special Tool 9122 + 9122/2).





3. At idle speed the oil pressure should be 2.5 bar or more.
Have a second person accelerate the engine speed to 4000 rpm. Read oil pressure from tester. The value should be greater than 4.5 bar.
