Anyone any experience on these?
It's 2008 2.5cdti (G9U) vivaro
Has car with spanner and coil light illuminated.
Has fault code for oil dilution, has had an oil and filter change.
But fault returns straight away KOEO
Had autel maxisys, snap on and vaux com.
Tried resetting service light several times.
Where is the sensor that measure oil quality?
Dpf is reading 300kpa at idle is this a little too high?
No option to do forced regen on any tools I've got.
Any ideas/ input appreciated
Thanks guys

My experiences for this year have been limited to M9R, but I would say that your best choice of the tools above is the vaux_com, if it's genuine. Nothing else works reliably on the Vivaro, they all just read out rubbish that takes more of your time than it's worth. 300kPa, or 45psi in older-person-parlance, seems a bit high for a DPF delta-pressure at idle airflows. Is this from the scantool, or from a remote pressure transducer? |

Yeah vaux com seems I have more data available
Doesn't have any options for regen or anything so I'm basically stuck ATM of knowing dpf is reading high but can't regen and can't reset oil quality code either.
What I'm looking to do is find sensor and test it to find it it's at fault or how I go about removing this code.
As I suspect if this code is present it won't try do a passive regen.
Do you think tech2 will allow any more than vaux com?
Or am I better trying to find someone with renault tool?

Forgot to say that's scan data for pressures.

Do you think it's simply then that I need to find a better level tool and reset it and regen? What is calculation made from? |

Oil degration is normally calculated from a number of different factors
Stop/start driving, temperature, load,rpm, etc etc etc

Forgot to say that's scan data for pressures. I would suggest getting a second opinion from a pressure gauge to work-out if the scan-data is correct or not. If that is a true reading at idle speed, the DPF should not be regenerated on the van. If in doubt, you need to remove the DPF and get it professionally cleaned on a proper facility, or replace it with new. The oil dilution calculation may well have contributed to the blocking of the DPF, as the active regeneration would have been inhibited if the oil was showing as thinned. The crucial thing here is that the oil service needs to have occurred, before resetting the oil-change counter in the ECU (with a decent scan-tool), before refitting any new/overhauled DPF - otherwise the same thing is going to happen again. This is just another brick-in-the-wall for modern diesels; when you cannot get a regeneration on a full-sized van (in normal use?), then something is badly wrong. I could understand a small diesel car having trouble in town, but not a workhorse. |

I had a dpf sensor give an off the wall reading like that before and when I disconnected the hoses, out fell a load of water and ash. New sensor was needed.
If you disconnect both hoses from the sensor, does the reading go to zero?

Sorted this today
Got hold of a tech2. Dpf regen
Reset learnt values and reset service light.
Van now drives great
Thanks for help guys
