Model Year:

As of 2012

Concerns:

Oil guide housing

Information:

Oil leak (“sweating”, drops of oil) on engine in oil guide housing area
We have discovered that the cause of some leaks in the specified area could not be detected and
determined definitively in the dealer organisation when attempting to resolve the complaint “Oil leak”1 .
As a result, some of the measures that were carried out were not always effective.

Oil sweating, drops of oil

Proceed as follows in the event of a complaint:
Information
Test drive:
 Before doing any other work, the oil leak/oil contamination area on the engine must always be
cleaned and sprayed with a suitable leak-locating agent/leak detecting spray (commercially available).
Then, perform a test drive.
After the test drive, check the engine for oil leaks.
 From past experience, we have discovered that the vehicle only needs to be driven a longer distance
(> 620 miles/1,000 km) if this "short test drive" is not sufficient for precise leak detection.
Please discuss this with the customer.
Definition:

“Oil sweating”
Oil is visible; however, the amount of oil emerging is not significant and/or does not form drops of oil.
There is no oil on the underbody protection, chassis components, front-axle carrier or on the ground.
So no action is required in this case.
“Drops of oil”
A significant amount of oil is visible; the emerging oil forms a trail with drops of oil. Oil is also visible on the
underbody protection, chassis components, front-axle carrier and on the ground.
Carry out the following measures (1 to 4) in this case – as required.

Overview:

The listed topic relating to oil contamination on the engine is not exhaustive.
