Sadly, the excessive oil change interval, the DPF regen oil dilution issue and the design are still contributing to failures on recent models - there was a 2022 with 45k on the FB post this morning. Frankly, as a Ceng, its a pig of a design but expecting an oil to do 20k with this arrangement just isn't logical.
It’s not just the 4 cylinder ingenious engines… go to about 6:10 in the video below to see a 6 cylinder one… OK the owner didn’t change the oil annually but mileage was within the interval.

@tommustoe - not familiar with Disco Sport but if anything like our late model Freelander 2, if you’re running halogen bulbs in projector light units then they blow very regularly. In the end I gave up buying them every 3-6 months & bought an HID Xenon replacement kit for about £70. Problem solved & light throw is way better too. Link to website below if it’s any use.

JLR’s plan was I believe to “bolt” as many of the 500cc lumps together as you need giving you a 2.0, 2.5, 3.0, etc giving you a family of engines based on a standard set of units - not as simple as that but the premise is there. Sadly, the Euro6 DPF gen arrangements and IMHO the unrealistic 21k miles/24 months service interval means that some engines especially those doing not so many miles in short journeys where the regen cannot complete are driving around with dishwater for oil. Sadly, sum of its parts which is a pity as I actually live the vehicle and it’s proven to be a very good stalking/family compromise.
I was bricking it on Friday when I put the dS into Mike Allen at Swindon to do the timing chain stretch test. Absolutely staggered to discover that there's no stretch at 95k miles and that the chain rattle is actually a detached engine heat shield that needs welding back on - PHEW Moreover, what I was thinking as a possible PTO/gearbox whine is a idler pulley! Looking at several hundreds therefore and not thousands! More importantly, I can use it so was back out stalking on Friday night
However, before anyone poo-poo's the timing chain issue, I have come across the 2 attachments below from JLR that provide the full context - you could not make this up! Design winning over engineering - need I say anymore
There are 2 Range Rover models that would scare me. I’m ignoring the non 4x4 like the Evoque which has its own issues as well and anything under 10 year of age as beyond my pay bracket.
The disco 3 litre v6. Poor oil circulation which is evidenced by the amount of snapped crankshafts. Well documented.
And the disco sport with the inginium engine. Terrible reputation for timing chains and the stupid service intervals. If you had one from new and serviced it, or changed the oil every 6,000 miles, that would probably reduce the issues significantly.
I honestly have no idea what car I would go for to replace my Freelander 2 when it finally goes to the great stalking ground in the sky. Hopefully not for a considerable time.
A friend of mine with a 2019 Evoque has just been hit with an £8k repair bill for the timing chain, oil blockage issues and a few other faults. It's a low mileage, well driven and regularly serviced car
