Note:  

Observe installation position of 
adapter: The tapered connecting 
socket of the adapter is screwed to 
the pressure hose of the tester. 

If the LED lights up:  

If the LED does not light up:  

-  Remove Oil pressure switch -F1- 

and screw into tester. 

-  Screw tester VAG 1342 with 

adapter VAG 1342/14 into oil filter 
bracket instead of oil pressure 
switch. 

-  Connect brown wire of tester to 

Ground (-). 

-  Connect diode test lamp VAG 

1527 B to battery positive (+) and 
oil pressure switch using adapter 
cables from VAG 1594 A. 

   LED must not light up. 

-  Replace Oil pressure switch -F1-

   Checking oil pressure  

  

  

-  Check oil pressure at different revolutions: 

  

  

   2,000 rpm: 3.0...5.5 bar 

  

  

   above 2,000 rpm: maximum 7.0 bar.  

  

   If the specifications are not attained:  

  

  

-  Repair mechanical damage, e.g. bearing 

damage. 

  

  

   At higher engine speeds oil pressure must not 

exceed 7.0 bar. 

  

   If the specification is exceeded:  

  

  

-  Check oil galleries. 

  

  

-  Replace oil pump if necessary

Cooling system components, 
servicing 

  

  

CAUTION!

 

  

  

When performing repair work, especially due 
to the confined conditions in the engine 
compartment, pay attention to the following:

  

  

 

Route all types of lines (e.g. for fuel, 
hydraulics, EVAP system, coolant, 
refrigerant, brake fluid and vacuum) as well 
as electrical wiring so that the original 
positions are restored.

 

  

  

 

Make sure sufficient clearance to all moving 
or hot components.

 

  

  

Note:  

  

  

 When the engine is warm the cooling system is 

under pressure. If necessary release pressure 
before commencing repair work. 

  

  

 Hoses are secured with spring-type clips. In 

cases of repair only use spring-type clips.

    

 Assembly tool VAS 5024 or hose clip pliers 

VAG 1921 are recommended for installing 
spring-type clips. 

 When installing coolant hoses route stress

so that they do not come into contact with other 
components (observe markings on coolant 
connection and hose). 

Cooling system components, servicing

   Perform cooling system leakage test with 

cooling system tester VAG 1274 and 
adapters VAG 1274/8 and VAG 1274/9.
