Oil leaks from upper engine areas, diagnostic guidelines
Condition
Misdiagnosis of oil leaks from upper engine areas may result in unnecessary replacement of camshaft adjusters and/or camshaft adjuster gaskets.
Tip:
Please note revisions to the procedure in this TSB. It is no longer necessary to replace the cylinder head cover gasket prior to other repairs.
This TSB applies only to oil leaks from the engine.
Technical Background

Production Solution
Not applicable.
Service
1. Visually inspect area of suspected oil leak.
2. Classify suspected oil leak (Category 1, 2, or 3) according to table included in Audi Warranty Policies and Procedures Manual. (See "Categorization of Leaks" table.)
A) If suspected oil leak is classified as category 1 or category 2 with a customer complaint:
1. Clean oil stained area.
2. Explain to the customer that oil residue on engine (suspected oil leaks classified as category 1 or 2) may be result of spilling during engine oil top-off or normal gaskets "sweating" and this is not indication of technical malfunction.
B) If suspected oil leak is classified as category 1 or category 2 without a customer complaint:
^ No repair necessary.
^ Oil residue on engine (suspected oil leaks classified as category 1 or category 2) may be result of spilling during engine oil top-off or normal gaskets "sweating" and is not an indication of technical malfunction.
C) If suspected engine oil leak is classified as category 3 only with a customer complaint:
1. Add oil dye to engine oil (recommended).
2. Optional step: If necessary, clean oil stained areas to identify the source of the oil leak.
3. Perform test drive. (Five miles or more is recommended.)
4. Following test drive, inspect engine to verify if oil leak is still present.
If, after the test drive, the engine is still leaking:
5. Locate source of oil leak.
6. If oil leak is traced to a specific component, service manager authorization is required before any other repair is performed. The following pictures must also be taken and attached to the repair order:
^ One picture of the leaking area prior to repair, clearly showing the oil leak (if more than one leaking area is present, one picture for each leak is necessary).
^ One picture of the vehicle VIN.
7. Repair oil leak as necessary.
D) If suspected engine oil leak is classified as category 3 only without a customer complaint (add-on repair):
1. Technician must follow procedure for add-on repairs as described in Warranty Policies and Procedures Manual.
2. Then proceed with repairs as described in Step C.
Cylinder head cover gasket, installing sealant at critical points
1. Old sealant and oil residues must be removed before new sealant is applied. Thoroughly clean sealing surface.
2. Before installing cylinder head cover gasket, apply a small amount of sealant on six critical transition points of sealing surface on cylinder head.
Sealing transition points between double bearing cap and cylinder head (2 points):
Apply small quantity of sealant Part No. AMV 174 004 01 to sides of joints (Figure 1, arrows) on upper sealing surface of cylinder head.
Sealing camshaft adjuster/cylinder head transition
(4 points):
Apply small quantity of sealant Part No. AMV 174 004 01 to sides of joints (Figure 2, arrows) on upper sealing surface of cylinder head.
Tips:
^ Apply sealant prior to installing gaskets.
^ Sealant is considered shop supplies and may not be claimed under warranty. Also, additional time to add sealant is not claimable under warranty.
^ Always refer to the Repair Manual and published Technical Service Bulletins for latest repair information.
^ In cases where parts are replaced, perform test drive to verify oil leak is eliminated.
^ If oil leak is traced to cylinder head cover gasket, you must file the claim under Service no. 1580.
