Harumph ... just getting that outa the way

Battery charging resolved, got the list of fitted options off Topix - and no the customer centre did not provide they didn't even respond before that's suggested - however Topix IS a rip off - you can't even download the darn manuals or handbook unless you are prepared to sit there and do a section at a time - except the sites so flakey you need to keep putting your VIN back in or it says you don't have permission ..

I have had to bite the bullet and book the car into Jaguar - yes Jaguar - not one single independent wanted anything to do with the airbag issue the car came to me with so I guess this is going to cost a grand or so - not best pleased.I have however orderd a parking sensor and the impact sensor and will replace those myself - front bumper cover off in less than a weeks ownership has to be a record.

Rear window cracked inside (not outside) so **** there goes another grand. that makes two

Fuel door - opened fine - won't latch closed again though what's the trick ?

Drivers headlight has water inside - somebody has been busy around the rear connector and top of the lens with silicone sealer - guessing a new light is also needed. and yet another grand and that makes three

One of the keys is junk so need a key too ....

Car has the wireless headphone option - but no headphones present

Not bad for the first 7 days - don't worry I got it for a good price I thought the airbag fix would be straightforward but it sure isn't

 

Its only money

 

Sometimes if it looks too good to be true, it is too good to be true

 

Sometimes - I'd go with always - my luck don't roll that way.

Everything I planned for except the reluctance of any Jaguar specialists to even consider trying to resolve, the only reason I'm even considering using somebody else is the MOT is up in a couple of weeks, it is too damn cold to be rolling around outside

I'm still in half a mind just to let the ticket expire and just send the RCM away and get it reflashed because I'm 95% certain that there is nothing wrong but this stupid self destruct Jaguar seem to have built into the RCM that can have no basis except revenue generation

Those that declined to assist will be remembered - every single one that declined will never be called again by me - I'm not interested in supporting a business that wants only an easy life - yeh yeh yeh I know cutting the nose off - that's the excuse that allows companies to take a dump on you and you keep going back like a moth to a flame - wasn't like I was asking them to work for free.

 

BenKenobi,

Don't loose faith, we are here for you, we just might not have had to deal with your particular problem.

My 2012 5.0 N/A recently threw an air-bag caption after my wife exited the car. Hey, WTF! I shut down the car, restarted and all was fine....(In the front of my brain is "BATTERY". Nothing happens for a couple of weeks and then all sorts of minor stuff pops up. (OK Air-Bags aren't minor)....well, if you'd visited this forum 15 years ago batteries are the work of Satan. They still are

You can reset the Caption with a good scanner.

You can try a hard reset. (Works 95% of the time)

Buy a new battery, you are going to need one soon anyway.

Best of luck,

wombat

 

I have two scanners - an older iCarSoft i930 and a newer XTool D8 - neither will clear the RCM DTC's but both will read them, there is nothing wrong with the harness - I substituted the airbags, each for a 2.5 ohm resistor - the RCM still declares the connectors open circuit - they are not. This has to be an RCM reset required and I'm not going to let impatience cost me a four digit sum - I will bow to Jaguar service only when all other options are exhausted but if you ask me this RCM 'self destruct' is opportunism at its worst, safety has nothing to do with it, I can't see a single firing of an airbag circuit damaging the capacitors that perform that function (which I believe are actually voltage boosted to 24V DC).

I have recinded my booking with Jaguar for now as Monday was going to prove inconvenient anyhow given that we are one car down already - they want over £700 for a new RCM and they still want to apply £210 per hour * 4 and +VAT on all that - I can get the RCM reflashed for £30 - no brainer will just need to put up with no car till Jan - not bothered over much I have more than one. It will cause challenges in the new year of course as the MOT will have expired.

New Exide AGM installed - not sure if it needs coding - still learning the XTools capabilities - the XF was easy. I don't necessarily think batteries are the work of satan but all the electrical demands on these cars certainly are - I was after replacing the XF with an old school car that wasn't wall to wall computers and such - not sure what happened to that plan.

I have a new headlight arriving in a day or two, not been able to collect the parking sensor as a car that was in for service yesterday is still there and the wife unit is out in the other (and that threw a handbrake electrical fault this morning - damn it was cold here last night)

 

Ben is this car a salvage car by any chance asking out of curiosity as I see you have other threads going

 

Not to my knowledge, nothing recorded, it is ex Scottish government but was also a press car in its early life - was one of the first 500 XJ's.

It has come to me in a very sorry state and has suffered some because I don't think the previous owner could really afford to run it, this is not a criticism, in my youth I did the same. Maintenance has either been skipped or shortcuts taken, the car has clearly had some kind of 'event' and I believe that event discharged the pedestrian protection system there is however no evidence at all that any metalwork got bent (and I do know how to spot such things), the bonnet rides a little high at the back under the windscreen but not excessively so, from a few feet away you would be hard pressed to spot it but I don't think the hinges have been reset.

The reason for all the threads is that I am a sucker for a basket case - take it as a challenge - but I don't tolerate less than 100% when it comes to stuff working as designed, I am trying to source all possible wisdom to aid with the cars recovery - sadly it seems much like the XF that owners of them tend not to get their hands dirty, with only a very small minority venturing into the undergrowth. JLR don't make that easy in any case and the diagnostics and part sourcing for Jaguars has always been a challenge since parts are rarely marked with the part number Jaguar uses and most of the dealers around me will get you the parts but they won't disclose the numbers - protectionism in my opinion but that's a different soapbox.

I had to go to half a dozen sources to be sure the headlight was correct and did so using 'consensus' - the large number often quoted is not a reliable one

 

Thanks Ben , you seem to know more or less what your doing so good luck , only place I have herd of are likes of eurojag for parts they seem to have a lot , also check out the stickies section on here or google you might find a YouTube video or to over their worth a try . ATB. George05

 

As wombat suggested, you should try a Hard Reset. That can often fix electrical glitches. It drains the volatile memory from various modules and resets them to the factory defaults. See Post #3 in this old thread:
XJ Hard Reset

 

I haven't, there's nothing to lose trying it is there so I shall.

 

In case anyone here needs to replace the crash sensors at the front there are four of them, they aren't particularly well indicated or distinguished in the service manual. There are two high up that support the pedestrian protection deployment and lower down where you can't see under the headlights are two more.

The one on the left is C2Z1166 these are the pedestrian detectors, the one on the right are the new form of the C2D3537 and are those below the headlights. There are two of each one left, one right, as you can see the numbers on top are meaningless, the one below the headlight I doubt you can change without pulling the headlight which means pulling the bumper cover also. Fortunately I need to do both anyhow.

Edit : I had a chat with Jaguar re the RCM 'self destruct' and it is by design and it 'is' safety related but not how you would suspect. The RCM unit once airbags have deployed cannot be used again unless it is replaced (official way) or erased (unofficial way) - the reason is to prevent spurious triggering post accident when recovery teams may be at work and occupants may be trapped so it is for safety but not in ways you would think. Near misses are counted and issues they cause can be reset, failed sensors can be reset, airbags if triggered require RCM replacement no codes will clear if crash detected = true.

 

While I believe the pedestrian collision system is required in some countries (including UK maybe?), it's not required in the US, and as such I don't know if any U.S. XJs have it. I know my wife's doesn't.

I expect it wouldn't be practical for you to purchase parts from a US vendor, but you may be able to use their websites for reference for parts.
One example that I use which makes it easy to identify part numbers is:

Wholesale Jaguar Parts Online | Jaguar Annapolis Parts

 

Appreciate the link - I used to use one in the US but it stopped working, can't recall the name.

This system is just one of those fantasies of the minorities - apparently stepping in front of a moving vehicle isn't supposed to be dangerous or stupid - so we have a system that will do thousands of pounds worth of damage to drive up insurance premiums so that idiots can pay more attention to their smartphone than where they are walking.

 

Whenever possible, we should patronize our Forum Sponsors, as without them this Forum would not exist for free.

I've bought OEM Jaguar parts from SNG Barratt and have been pleased with their prices. Tell them you're a Forum member and ask for a discount. They're headquartered in the UK and have offices and warehouses in the USA and Europe. I noted that the OP is in the UK.
SNG Barratt

 

Whilst I appreciate the sentiment I have 5 days left to pass 'inspection' or the car is no longer considered legal to drive, niether SNG Barratt nor DMG would guarantee delivery before today, these airbag things aren't parts you can just take a wild guess at on a website, it took a while to track down the correct numbers - as an ex government car it seems to be hit and miss if non jaguar sources can even find the car, so that I can get this done at the weekend - sometimes needs must I'm afraid - in fact it was DMG that recommended I go direct since they would only order from Jaguar anyway.

For what it is worth I have spent a four figure sum with SNG, DMG and Simply Performance having spent in excess of 12k on parts for my XJS refurb not to mention stuff for the SV8 when I had it so your hint is unwarranted.

 

What hint is that? What did I write that offended you?

 

Added zero value to the questions I am asking and made the assumption that I don't.

That figures. You can't spell "assumption" without, well, you know.
