Technical Bulletin
Service
Tip:
This bulletin only applies, if the symptoms described here are identical with the damage on the customer vehicle.
Check the damage as follows:
 Remove the engine cover according to the repair manual.
 Loosen the intake hose on the turbocharger according to the repair manual.
 Check whether the impeller housing shows signs of contact with the turbine fan.
 Check whether the shaft of the turbocharger turbine fan:
 Has excessive free play.
 Is damaged.
 Is broken or seized.

To confirm a broken shaft on the turbocharger the diesel particulate filter (DPF) must be detached on the
turbocharger. This is the only way to check the turbocharger for damage and engine oil ingress on the exhaust
side (figure 1).
If no damage is found this technical bulletin does not apply.
 If turbocharger is found to be damaged, the DPF must be reattached at the turbocharger before proceeding to
the following steps:

Tip:
In addition, an endoscope can be fed through the threaded hole of the removed oxygen sensor to check:
The exhaust side of the turbocharger for damage and engine oil ingress.
The DPF for engine oil ingress.
Note:
The complete engine oil circuit must be flushed out before replacing the turbocharger to avoid a repeat repair. To
do this, proceed as follows:
Step 1
 Replace the oil filter according to the repair manual and thoroughly clean the inside of the oil filter housing.
 Drain the engine oil according to the repair manual.
 Unscrew the banjo bolt for the oil supply pipe on the cylinder block. Replace the banjo bolt with the hex head
bolt with part number WHT 005 747 (figure 2, in green) and tighten it according to the repair manual to block oil
supply to the damaged turbocharger.

Figure 2
Note:
Flush out the oil circuit while the faulty turbocharger/particulate filter is installed and the intake hose removed from
the turbocharger.
 Fill up the engine oil according to the manufacturer guidelines.
 Run the engine at idle speed for about 15-20 minutes.
 Replace the oil filter according to the repair manual and thoroughly clean the inside of the oil filter housing.
 Replace the oil filter housing cap (03L 115 433).
 Drain the engine oil according to the repair manual.
