Ohhh.... Soooo want a D5 BUT!!
Hey Guys. I've been following this thread trying to suss out whether I should risk purchasing a D5. Currently driving a 2015 Audi Q7 but would love to purchase a D5 mainly for the added room as I need 7 seats and have a teen in the 3rd row most days and just love the new meaty looking design. I was initially looking a 2017 HSE or HSE lux with dynamic pack (love the black vents and grille) and had one picked out then came across some threads describing the FIO issue and I'm now nervous lol! My husband has refused for years to buy another LR after owing a Freelander about 12 years ago which spent most of its time in the garage. I've now persuaded him to give the Discovery a chance but if I end up with these issues I'm toast! Our local LR dealer is about 70 miles away so can't just call in every month for an oil change. To summarise I'm getting that a MY2018 within the VIN range of N222 can be 'fixed' with the software update. Hauser has, I think, a 2017 which he seems to think is now fixed with software upgrade. Is this correct? Also, does this issue seem to happen with all 2017's with the TD6 engine or just some of them.... I am thinking of the 3.0 as we tow a caravan most weekends so would be presuming we would need more than the 2.0L. Anyone any words of wisdom cause I so want one lol?...

My SD6 is almost at 10,0000 miles now and has not needed anything except fuel, washer fluid and adblue. It's still on schedule for its first service at 1 year old (just under 16,000 miles).
MY2022 D5 HSE D300 - with extra nice bits added
MY2019 D5 HSE 3.0 SDV6 - sold to a dealer for a crazy price! -

First post for me. I currently have a Disco Sport and I keep wondering whether to swap up for a Disco5. I got a link here after being on the oil contamination thread on the disco sport forum!
I have a few questions which I am struggling to understand from this thread.
How do I distinguish a MY 17, 18, 19 model? The only difference I have noticed is they either have analogue clocks or once on the 18plate, the virtual dashboard.
Is there a fix for the MY17 service occurring too soon, and does it work? Or am I better looking for a MY18/19 model with the TDV6? Does the SDV6 have the same issues?
The Ingenium engine, does this suffer the same lack of passive regeneration as the TD4 in the DiscoSport due to a silly positioning of the DPF, or does the twin turbo SD4 and DPF location resolve that?
Lastly, is there a service reset procedure if I wanted to do my own interim oil services like I do with my DS? The DS was a combination of pedals, doors and bonnet.
I noticed that someone asked how often the engine regenerates, the answer is a long one! I haven't measured it continuously yet using data from the engine, however I have seen some data which shows around 200mile (or less) for the TD4 on the DS, and that was motorway driving! Driving style will influence how quickly the soot collects in the DPF, but mostly, if you for example are driving around town stopping/starting DURING an Active regeneration then the DPF will not completely empty and will stop the regen cycle around 30% soot load. Compare that to driving on the motorway and an Active Regen cycle starts, if you continue on the motorway without stopping then the regen cycle will reduce the soot load all the way down to about 10%, so that is 20% of your regeneration time problem. The other is with short journeys the engine will not start the cycle usually until at least 5 minutes after start, whether it is warm or not, so if you keep doing short journeys (<10mins) then you will keep loading soot into the DPF and not allow it to clear (often it takes 20mins to complete a regen). There are lots of parameters about whether the car will regenerate or not, but easy ones to note are it can't have any engine caution lights and often needs to have more than 25% fuel in the tank, so if you're doing short journeys when low on fuel with a caution light on the dash, you will be getting towed to a garage pretty quick! I had read in the engineering notice circulating that the regeneration of the TDV6 takes longer due to slower heating, but it wasn't clear to me if this was talking about an Active (post fuel injection) or a passive (natural DPF heating from exhaust)
I still help out quite a bit on the VAG forums and on the EA189 fix reversal (think the 2017 Evoque DPF problems but throw in an EGR and turbo seals and injectors as well for good measure, and a parent company that flat denies there is a problem and does everything as 'good will'). We receommend using an app called VAGDPF which monitors the regeneration and EGR of the engine via an ELM327 like the Carista, sadly its Android only and VAG cars only.
I noticed recently that Torque Pro App can show DPF inlet temperature, I have not tried it on the LR yet, but it could be a good way to monitor what your DPF is up to, (if DPF inlet temp suddenly increases to around 600c then an active regen has begun).
Below is a screenshot of VAGDPF. It also shows the EGR cycling, as well as post injection, but it also helpfully shows how full your DPF ash load is (around 70g is the end of life for a VAG).

Brilliant, this helps quite a lot on which model to buy then, I will probably look for the 18/19 model unless the SD6 suddenly appears on the approved used market.
Is it the same SD6 engine that is in the RR Sport?
There are quite a few SDV6's in the approved used market.
Hopefully picking mine up within the next couple of weeks

Re: JLR Diesel Dilution
It's been revealed that JLR always knew about the engineering issues which cause excessive oil dilution and DPF clogging on the EU6 diesels. Someone thoughtfully coined the term "driving style" as a way for dealers to deflect attention away from the unresolved engineering "challenges", conveniently pushing the blame back onto owners.
The D8 chassis SUVs are known to have the worst problems with DPF clogging and oil dilution according to JLR. This is because the forward bulkhead is too tight on the transverse engine for the DPF to fit straight onto the turbo, as on Jaguar XE: therefore it lives under the floorpan more than 2 feet further back. Discovery 5 and other D7u cars were not expected to suffer as badly from dilution but the V6 is not totally in the clear because its DPF, though tightly coupled to the DOC (same can), is still not ideally positioned relative to the heat source (turbo outlet).
On the DS and Evoque they are rolling out a software "enhancement" to increase the dilution threshold on all vehicles to 10% which will help quieten down customer complaints and reduce the number of rejections. JLR seems to have little or no interest in the predictable long-term effects of diesel dilution, presumably because these will mainly present outside of the warranty period. As if to underline this interpretation, the second-hand warranty period has just been cut to 12 months (from 1st Sept 2019), further reducing JLR's liability for DPF and lubrication-related problems.
