White smoke from the exhaust system and juddering when the engine runs at idle speed for some time - V6 TDI 2.7l / 3.0l TDI.
Technical background
Mechanical wear of the needle attachment of the injector leads to an increased fuel injection into the combustion chamber. The fuel is not completely burnt, which causes white smoke (unburnt fuel) or juddering when the engine runs at idle speed for some time.
This complaint occurs only on vehicles with more than 50,000 km.
Production change
Modified injectors from:
8E47A040360
4F37N026750
4EX7N004204
4L*7D049162
Measure
Try to reproduce the customer complaint so that it can be clearly assigned to this TPI. The following repair must only be carried out, if all the criteria (model/type, chassis number, engine/gearbox code, PR number(s), software version, code etc. ) match exactly. Otherwise this solution won't work and repeat repairs may be necessary. In such a case, we may reject the warranty claim and redebit the parts.
Read the measured value blocks 72 - 77.
3 values per measured value block appear there (for 300 bar, 600 bar, 1000 bar).
Should the values be higher than minus -45 ms (example - 60ms) or
on digit 2 be
higher than minus -15 ms (e.g. 20ms),
the needle attachment is worn and the injector is incorrect. To avoid repeat repairs, replace all 6 injectors.
