One DRL is half as bright as the other.

Following with interest and well done in pursuing a solution to this. Sounds like there is a much better understanding of the issue.

One question I have is why does this appear to only affect the near side DRL. Has anyone also seen this on the offside as well??

Fantastic and interesting stuff by forum members WShudds and Tim Atkinson.
Also, the follow-up by member lokiinlove, in support.

Keen to hear progress and any crowdfunding required….

Hi Nigel, the failure rate is roughly 17:3 left side versus right side, probably because of temperatures around the headlamp enclosure, though I feel that's a bit academic. We're tooling to make replacement parts in pairs, as that's the best manufacturing option. It may be that the rate of right-side failures goes up with time, depending on the relationship between absolute temperature and exposure time to that temperature etc.

I'm following this with interest as I plan to buy an F-Type early next year. From my research on this forum and watching many YouTube videos, I was favouring a 2019-2020 V6S RWD, but also considering a P450. I have sat in a car but haven't had a test drive yet. Most of the cars on offer from dealers come with either no warranty or a short warranty, and I know you can upgrade or extend at a cost, but looking at the small print most warranties seem to exclude more than they include, or have very low limits on parts and labour prices. One I saw insists that you have the car serviced every 6 months.
I know the Jaguar Approved warranty is better, but not seeing many V6 offered.
How prevalent are these DRL failures, and if buying now, would you think twice about buying a 2018 - 2020 V6 car because of the potential cost of headlight replacement , and go for the new style 450 instead?

I still think that it's only a small proportion of cars affected by this issue. If you have the budget to buy a 450 then the small chance of spending £2K on a new headlight unit shouldn't be a worry. I'd still take the V6 Pre GPF but I daily mine.

It's possible to get the Jaguar extended warranty if you have a paid-for inspection at a dealer and they pass it as okay. A few i-Pace owners have done just that after buying used from non-JLR dealers, cost around £200-£300 it seems, then about a grand for the warranty, which covers pretty much everything.

That said, I haven't had a warranty on mine since 2020 and all it's cost me is routine serrvicing (at a trusted independent), tyres and fuel.

I would not think twice because of the potential headlight issue. As the recently posted updates in this thread indicate, I think it's just a matter of time until there's a good and probably reasonably priced solution to this issue.

I'm biased but would definitely go for a pre-GPF RWD V6S or 400 because I think that's peak F-Type in in so many ways. Whether to go for that or a P450 is a question of what you expect and what flavour of F-Type you would like because they're quite different. One sounds and feels like an Italian sports car and one sounds and feels like a German muscle car as someone put it. Having said that though, if you want an F-Type with a V8 and like the different front end, out of the 2nd facelift cars I think an RWD P450 is the most interesting one not least in terms of value for money. If you care about straight line grunt you can unlock a P450's remaining horses and get some 600 hp with a simple remap.

Anyways, impressive progress with the headlight investigations and hats off to those who work on them.

DRL disease has hit me now. MY20 P300. Earliest main dealer can look at it is 25th September! Ridiculous, I suppose now they stopped making any cars Jaguar just don’t care.

Was phoned up by dealer in Taunton on the 24th September and told they couldn't do it, no staff. Well wonderful. So booked elsewhere. Dealer diagnosed internal circuit failure and Jaguar warranty agreed to cover it - earliest fix date now late December! Quoted just under £3200. Good news is that I had the MOT and service at the same time and car passed MOT without advisories despite the dimming. So perhaps not one to worry overmuch about if you haven't got warranty cover, and hang in there for the future repair service.

Interestingly the dealer claimed this was the first one they'd seen. Quite a few on Land Rovers apparently but not Jaguars.

Which warranty is covering this repair or is it just being done as good will gesture? I'm asking as you said not to worry

Jaguar extended warranty. £1026 in Jan this year but looking a good call right now.
