Should I stay or should I go?

I've had my 2016 3.0d XFS for over 6 months now and I love the car. Love driving it, love looking at it, love it.

However, there's a long list of issues that knock the gloss off it. (See below)

I'm thinking now, should I invest in trying to get some or all of these resolved, or get rid for something a little less needy.

In summary...

Regular orange engine light caused by one or more of these ECM issues
-turbo overboost(frequent)
-glow plug control voltage (frequent)
-nox excedence
-exhaust fluid quality

Additional non PCM error codes in chassis control and other modules, bus comms etc.

AC only blows cold air on passenger side. Driver vents blow ambient temp.

My Android phone(s) have a torrid time initially connecting to the car over bluetooth

My foot well lights have flickered and expired

My rear driver's side door retains water

Remote start works only occasionally

I have been dealing with engine management light by clearing powertrain codes in Autel, and this allows DPF Regen etc., but those codes come back almost immediately and I figure need to be looked at.

The other items listed are minor, for sure, but added together are just a bit of a pain.

My worry is that fixing the main issues could only be the tip of the iceberg?

What would you do?

I suppose it depends on whether you have the time and inclination to try and fix those issues. A car is a hobby to a lot of the FMs here, not just a means of transport (as nice a means of transport as a Jag is) and just as long as it's driveable then these "issues" could be an intersting if not irritating, diversion.
On the other hand, if the issues keep you awake at night, get rid of and find yourself something less irksome.

It could be something simple and inexpensive causing the engine warning light.

Additional non PCM error codes in chassis control and other modules, bus comms etc.

I'd not worry to much about other fault codes lingering in other ECU's as they're possibly not causing issues. My Range Rover for example has 3 fault codes that won't clear:

Traffic Management Antenna Short Circuit yet the traffic management system works fine.
Speaker 1 Short Circuit yet the speaker works fine when you've got your ear to it.
Speaker 3 Short Circuit yet this speaker also works fine when you've got your ear to it.

Basically, don't get too hung up on the fault codes, fix what is giving your errors you can see on the dashboard and are causing issues with drivability. If you weren't reading the codes you wouldn't know they were there so they wouldn't be bothering you!

AC only blows cold air on passenger side. Driver vents blow ambient temp.

This could be due to heater flaps in the dashboard. On some cars there is an easy enough workaround that makes it not too expensive to rectify.

My foot well lights have flickered and expired

Could it be as simple as the bulbs have failed?

My rear driver's side door retains water

Could it be the door seal just needs aligning? There's also a drain at the bottom of the doors as water gets into them by design but it's meant to drain out. Check that's not blocked or obstructed by a misaligned seal.

Remote start works only occasionally

Has the battery been replaced? These cars are power heavy and an aging battery can cause all sorts of issues. If it has been replaced, was the Battery Monitoring System reset and told the battery was new?

Are you able to do work on the car yourself? If so, make a list prioritise the items in the order they bother you. If not, use the same list but get a local JLR specialist to do the work. For me, I'd sort the engine management first. Then run the car for a month or two to make sure it's sorted and then move onto the next item such as the air con. Jobs like checking the door seal and the bulbs in the footwell are easy to do your self and cheap to resolve so I'd probably do them myself in between.

If you're falling out of love with the car it might be time for a change. The only problem is, unless you're buying new, the next car could have the same or worse faults

Hope this helps.

David.

Thanks @dhallworth

That's my own line of thinking but I wanted to gauge opinions. My gut is that if I get the main issues of turbo overboost (likely sticking manifold) and glow plug controller voltage fixed, that would reduce significantly the instances of engine management light and subsequent failure to instantiate DPF Regen .

Everything else would be an inconvenience, at best.

Car drives superbly well, so would be a reluctant parting of ways.

I'm not particularly handy in a motoring sense. I've fixed the water in door issue but even getting to the bulbs is something if be reluctant to do

I would ask around or find a good Jaguar independent near to you, and go over with them exactly what you are telling us. Get an estimate of cost from them and decide which route you wish to take. Btw, I got myself some nice ice blue interior leds a week ago and all my flickering issues have gone. It really is an easy task but you have to get down on your knees for the front footwell ones

. Good luck, please keep us posted on the outcome.

Can I ask where you sourced the LEDs and if they were a direct replacement?
