Measures for slightly sludged engine:

Oil and filter change. Purge engine, i.e. normal engine operation

in neutral, or while driving, using oil from Sheet 229.3, 228.3, or

228.5. Drain off scavenging oil after purging process (approx. 1

hour). Repeat purging process if necessary. Refill using engine oil

from Sheet 229.3, or 229.1. The first oil change after clearing the

sludge should be performed after approx. 10,000 km or beforehand;

when doing so use engine oil from Sheet 229.3.

Measures for severely sludged engine:

Engines with severe oil sludging and caking onto engine parts

and into bores have to be dismantled and mechanically cleaned.

Tough sludge residue must not enter the clean side of the oil circuit,

as otherwise, e.g. the piston oil spray and the hydraulic

compensation elements may have their functionality impaired. Refill

using engine oil from Sheet 229.3, or 229.1.

The first oil change after sludging should be performed after approx.

10,000 km; when doing so use engine oil from

Sheet 229.3.
Warranty/goodwill regulations

If in combination with engine oil sludging a warranty/goodwill claim is

submitted, then a regular documentation of maintenance must be

presented. The ASSYST printout is to be filed carefully for further

reference.

Oil sludging in combination with an exceeded oil change interval, or

because of special additives in the fuel/engine oil are costs to be

borne by the customer.

The white filter surface of the TPM wheel

sensor is damaged or dirty

D
Tire sealant was used

D
Damage can be seen

D
The TPM wheel sensor is more than 5

years old according to the date of

manufacture (a).


Install


Replace all valve parts.

Observe different valve versions.

When replacing the TPM wheel sensor,

pay attention to the correct transmission
frequency (433 MHZ or 315 MHZ).

7
Insert valve body (3) with TPM wheel sensor

into wheel rim so that the radial bore (arrow)

for countering points upwards.
