Hi there

What type of driving do you do mostly ie: motorway or more short cold journeys

How much is the oil rising by and is of over a short or longer period of time

Kind regards ***** *****


Customer: replied 1 year ago.
It's mostly short trips. The oil level rises by about a litre in about 100 km.

Hi there Damien thanks

Ok in my experience with these dv6 1.6hdi engines expressing diesel into the dump has been most commonly Down to overfuelling from the injector tips

The first thing would be to inspect the tips of the injectors to see if they are wet as this could be caused on shut down of the engine the injector is dispersing its fuel at high pressure out of the nozzle past the tings and into the sump

Also ensure the software level is at the latest level as the 1.6hdi suffered software issues leading to overfuelling also

Multiple failed regenerations of the DPF can also cause this and doesn't always bring up codes of ie: a exhaust gas temperature sensor isn't operating as it should can cause failed regens which in turn caused oil dilution

If you need anymore help or advice on this issue please let me know and I will do my upmost to assist you

If you were satisfied with my answer /advice


Kindest regards ***** ***** and have a nice evening

Any positive feedback is kindly appreciated
