I become obsessive bout oil dilution. Information is what we all want, it seems that oil dilution is a factor of DPG regens. So the question must be how many regens does it take? I ask this because if it just takes 1 then you could have to change oil after the regen to combat dilution. This raises the issue of possible frequent oil changes, and in some aspects aligns with some people's experiences of getting frequent oil change service requests.

So it would be good to have this question answered. Also would be good to be able to tell when a regen occurs ? M16 SVD8 ,4.4 HSE with a few extras, Sold R50 , Wife SQ5 , BMW R1200GSW.

On my Honda, the fuel economy dipped, it felt a bit rougher, and there was a bit of a burning smell when it went through a re-gen. Obviously I can't say what the signs are on a RRS.
As for how much dilution per re-gen, I bet only JLR know (as if they are going to let that cat out of the bag).

Hi guys.

I have a hawk eye and nano com at home which I still use for my TD5 Discovery, I know this will do every land rover as long as you buy the right unlock code but will this give me all the info about the regens ?

I think I may get the unlock code for my hawk eye so I can access this data it's going to cost a few £'s but least I can keep a eye on data like number of regens and this way it will save me alot in the future at land rover Stealers

Anybody got a hawk eye or nano com unlocked for a SDV6 L494 sport ? What's it like for access into the Bcu, ECU etc ?

Thanks.

When your car goes in for a service, you can request the regen history, which is stored in the ECU, but seemingly deleted at each service.

But you do need to request it of a tech or service manager, the "agents " on the front desk never managed to pass the request on for me. MY2016 HSE D SDV6 - gone due to fuel dilution problems.

As my car will be a high mileage vehicle I want to design a proactive care and maintenance process. So far I think this is how things work:-

Service intervals are worked on an Algorithmic process that considers:

Time 12 months, Stop starts , regens , and driving style. Most likely time and regens force early mileage services.

Regens are based on exhaust flow differentials so as the DFP filter ages , with use, gas flow will become more restricted and I assume more regens will occur and more oil dilution.

My take from this is I will need to do more regular oil services if I want longer engine life.

Oil contaminants are measured Parts Per Million , which is really about abusive materials coming off engine components and circulating causing more abrasion. Longer the oil is in the engine more parts per million.

I tried to get some info from dealer board members may help here , What is the service life of the DPF ?

What is the acceptable oil contaminants for the designed service intervals, LR must have tested this to work out service periods.

Also wondering if out of spec contamination is a warranty issue, most likely not with out a high court challenge !

Overall I am happy with my car , the early oil change this time makes sense , only 1500 miles early based on Regens, so now I understand some of the facts I can take better care. M16 SVD8 ,4.4 HSE with a few extras, Sold R50 , Wife SQ5 , BMW R1200GSW.

I have read that a DPF filter should onlybe fulll after 100,000 miles. I have no idea how that milage is arrived at regarding variable occurrence of the re-gens as even after it won't be empty. They can, I believe , be removed and chemically cleaned out but as to ease and cost, I emagine we will find out. If the engine lasts that long that is.

Depends what you mean by "full".

If you mean residual ash deposits that won't burn off during a regeneration, I concur.

And that might well be removable via a high pressure wash, but getting the DPF off in one piece (Exhaust fixings after 100k miles are not exactly known for being easy to remove) could be another matter.

Certainly main dealers won't do anything other than replace it. And I doubt they will be cheap. MY2016 HSE D SDV6 - gone due to fuel dilution problems.

Found this on the WEB and it suggests the DPF life should be the same as engine life?

This is an Australian site for DPF cleaning but seems about 400 pound gets the DPF like brand new. Also noticed some fuel additives that claim they help DPF life and cleaning.

The "DPF Issue" affecting the Evoque and DS has now been officially labelled as a JLR-specific design/manufacturing fault by The Car Expert web site. On 14 August 2018 at 9:01 am Editor Stuart Masson, responding to yet another poster who had just been told that their driving style was the cause of a serious DPF problem, wrote:

It’s not the emissions limits, it’s the design and engineering of the manufacturer that is faulty. Plenty of other manufacturers have been able to build cars that comply with the Euro 6 emissions laws without breaking down every five minutes – but then reliability has never been Land Rover’s forte…

That's the kiss of death then, to aftermarket warranty claims. MY2016 HSE D SDV6 - gone due to fuel dilution problems.

Found the actual document JLRP00100, presume internal, that JLR have shared with Dealership Service Centres regarding protocols re dealing with early service or oil dilution.

Very useful fodder to use with dealership if you are getting any pushback or unhelpful behaviour (which I know is unlikely )

Apols if it has been shared before

Audi Q7 sales suspended in Australia
Diesel issues slow sales of full-sized SUVs.
1 / 1 photos


Audi has suspended sales of its full-sized Q7 SUV.
Vehicles powered by 3.0-litre turbo diesel V6 engines require an update to prevent people from tampering with the emissions management system.
Both the 160kW and 200kW versions of the Audi luxury SUV use diesel exhaust fluid additives such as AdBlue to reduce the effect of harmful particulates. When sprayed into a car's exhaust system, the urea-based solution helps exhaust filters trap particles which can be hazardous to human health.
Audi spokesman Shaun Cleary says the brand has suspended sales of new and used Q7 models to make sure the systems work correctly. A design flaw in the Q7 may make it possible to top up the car's diesel exhaust fluid reservoir with liquids that do not perform as intended.

"We’re working on a solution to improve recognition of the wrong medium [being added] to the AdBlue tank,” he says.
AdBlue fluid has been a problematic point for brands following VW's diesel emissions scandal. German manufacturers have been accused of colluding to reduce the effectiveness of AdBlue by installing smaller tanks in cars, and spreading the fluid too thin between service intervals. RRS P460e
