Hello!
I purchased a 2008 XKR portfolio convertible that is not starting.
According to previous owner the car failed to start after a detailing shop tried to jump start the car or some electronics parts were exposed to water during the detailing.

Currently the car is half paralysed electronicly :

1.the lights, horn, multimedia, seats,are functioning properly .
2.the doors windows are not functioning
3. there is no ignition at all.
​​​​​4. When I put the key in the solt I receive a message saying "check smart key " but the key can lock amd lock plus switch on the headlights.

I have checked if there was any trace of water on the following, but they looked good to me:
1. ECM
​​2. Front Bcm under the steering wheel
3. Rear bcm behind the seats
4. Imboliser
5. Fusebox engine bay

I have read some threads about the battery voltage that might be the issue however there is no any ignition , the dashboard is only showing that key message.

Acording to previous owner some garages (non specialists) tried to figure it out but they weren't successful and the obd scanner is flooded with codes.

I know I should take it to a specialist but please I would like to know your opinion about the above just to again some knowledge before heading there or it might be something common or simple.

Thanks

 

Welcome to the forums Gabriel,

I've merged your three identically titled threads and removed one of your posts which is effectively a duplicate of post #1 here. Post #2 has some additional detail so I have left it.

Hi again sorry for the mess!

 

It's nearly ALWAYS the battery. Learn that first and it will avoid headaches.
There is a slot inside the center console very near the rear with a triangle mark on it. That's the spot for inserting the key when the ignition doesn't find it. It's a "PUSH INSTALL PUSH TO REMOVE thing, so don't worry about it getting swallowed.
Again to the battery; First, remove that battery and get it load tested at a store or shop. That should be a free test. It is probably bad.
Next: Get a NEW battery, then CHARGE it with an actual CHARGER (10 amp or more) for many hours. Nearly every battery sold has been sitting around for sometimes a very long while.

 

Yup gonna try first with the battery scenario. I placed the key there in there and that message appeared on the speedometer "check smart key"
the thing is , the steering column cover is missing and the obd wire is dangling along with some thin wires . Done by the previous owner . I checked the immobiliser is still there and bcm too.

The car was neglected and was taken to unprofessional technicians

 

You definitely need the Electrical Guide:

Troubleshooting can be tricky enough at times but putting right previous 'interference' adds another level of complexity.

I don't understand why you bought a car that didn't run.

I do understand why the seller got rid of it.

 

You'll also need to view the workshop (service) manual, as GGG points out find and read/search the master documents i.e. the electrical guide and workshop manual in the stickies at the top of this forum. You'll find "check smart key" means "The smart key detected is not the correct smart key for the vehicle." It looks like you have a fundamental authentication issue as the key is not being recognized as valid. You'll need to find someone that has access to the dealer service software SDD to analyse the car and program a new key or if you lucky re-authenticate your key to the car.

 

 

Hopefully it was priced accordingly...

 

Obviously, it was priced right for the seller. Otherwise, he or she wouldn't have sold it.

The buyer didn't tell us how many miles were on that 2008 XKR or anything about its condition, service history, or if he had a Pre-Purchase Inspection done by a qualified Jaguar mechanic. He bought a cat in a bag with no idea of why it wouldn't start or how much it might cost to fix it.

What's the retail value in his area of a running 2008 XKR convertible in fair condition? Maybe $15K, assuming it has over 100,000 miles, multiple owners, accident history, and commensurate wear and tear. Without knowing exactly why it won't start and the cost of the parts and labor to fix it, how much would you pay for it? Even when you get it to start, how do you know that it doesn't have any other engine, cooling, or other running gear or other problems? It could cost more to fix it than it's worth.

I wouldn't touch it with your 10-foot pole!

Some lessons are learned the hard way.


P.S. The OP is in Dubai, and I have no idea of how much his car is worth or what it costs for repairs. Nevertheless, the above principles still apply.

 

Yes I started looking into those to have an idea which part has failed before visiting someone with access to SSD , just to save time and not to get ripped off.

 

obviously It was purchased for so cheap, and simply restoring cars is more like a hobby and personally rewarding .

The car has around 90,000km (actual) and for a fact it was running smoothly couple of weeks ago

Second I have a decent source for used/new parts in automotive industry

so why not?

 

Certainly could be a fun project or an utter nightmare, either way if it’s priced right, could be worth more for parts in the end.

Since you’ve not shared the full details of its history and only indicated it was perfect, then jump started and possibly water damaged it’s best to begin with getting the codes, check fuses and earth points. If it wasn’t jumped correctly that may be you’re first clue that something’s been damaged there. All assuming you’ve got a properly sorted fresh and full charged battery at the proper voltage and load value. The key fob not recognized could be related to the cluster which’s where that data’s stored.

 

That depends on your level of knowledge of the Jaguar X150, abilities, access to special Jaguar tools and equipment, and availability of parts that may be out of production ... and the size of your wallet and limits of your patience. Time will tell.

Good luck with your quest, and please keep us posted.

Read Ranchro50's epic thread "The Green Turtle or Let's Fix This Junk." I recommend that you start a similar thread to document your progress.

 

I really feel its not related to any modules like cluster, ecm , bcm ect. Hope just some voltage isuues
The key is operating normally in terms of locking/unlocking and all the other buttons of the key
gonna try with a new battery this week and see

I have some decent knowledge of the new jags to be honest and cars in general.
But this one is old and tricky thats why i am asking a lot.

nice thread ! Thinking of just keeping this . I'll change the title when i kick start it !

Thanks a lot and definitely will keep you all posted
