Hi Garry, not aware of anyone remapping a NA 5.0 litre XK, but several have undertaken this on the 5.0 litre XKR and have certainly noticed the difference, especially when combined with other tuning details. The folks at Paramount and Elite should be able to advise you, but most of the remapping is undertaken utilising Viezu maps. N6 JMX

Hi Gala, if you place your mouse cursor over your profile avatar - to the left of the post you are making, it allows you to go to your profile on the site and, if you don't have too many posts, you can easily find what post you are seeking. Simples! N6 JMX

It looks like a Series 2 XJ, produced between 1973 and 1979, but seriously modified by shortening the floorpan / chassis / roof and re-engineering the doors. Front bumper with the over riders is definitely of the Series 2 genre. Possibly started life as an XJC - the rear window, and rear quarterlight, and roof angles are more coupe than saloon in appearance, but cannot understand why anyone would go to this length to modify what is now a very rare and sought after model - if it were an XJC version originally that is. The door in view shows it was probably "engineered" by grafting the front end of a saloon's front door onto the whole of a saloon's rear door - to sit in the profile of the wheel arch. The front quarterlight in the saloon would have had a vertical trailing edge, whilst your photo shows an angled backwards trailing edge - akin to the XJ-S of the day. No Jaguar though ever had a single door that was profiled to the wheel arch on its trailing edge - rear door yes. Originally the Series 2 XJ was available as a short or long wheelbase 4-door saloon and the pillarless coupe came along in limited numbers part way into the production cycle. Your photo shows a car that has been cut and shut, albeit it may well have been a professional job in it's day. Something wrong with the registration though. The B plate is from 1983, which would be much later than the original donor car registration, PLUS, DVLA shows that B420 AGE was originally issued on a Silver coloured Vauxhall Nova, which this certainly isn't, in September 1983 - so maybe not as professional as first impressions. Interesting if others can shed more light on the machine. N6 JMX

For future info, where the vehicle is fitted with an Auxiliary Battery, this feeds the electronics whilst the vehicle is operating in start / stop mode, maintaining a constant 12V supply to the sensitive electronics. If you find, over time, that the start / stop function fails to operate, it can be due to either battery beginning to fail. The main battery obviously provides the capacity to physically crank start the vehicle, whilst the Auxiliary battery provides the stable voltage. Too many restarts in a short space of time, as in crawling traffic, will drop the main battery to the point where it automatically switches off the stop / start functionality until such time as the main battery has recharged itself with engine running. Typically a main battery in a stop / start vehicle will be of the AGM style, and 5-years should be considered as the typical lifespan of the battery before replacement becomes a need. N6 JMX

Hi Garry, that sounds like a plan. Please report back with what you learn. N6 JMX

Hi Dr Daryl, there are existing posts on this Forum regarding the non-availability of OEM updated navigation discs for those XK that are fitted with the DVD style Satnav System. As is oft times the case, there are 2 opinions as to the viability of the updated discs. In my particular case, I cannot advise that folks purchase "updated" discs from well known auction sites as they are effectively pirate discs that, in some instances have done more harm than good, i.e. they have corrupted the system and rendered the touchscreen inoperative. As many functions are controlled via the touchscreen in a Modern XK, this is NOT a good outcome. Despite having a "Jaguar" style label on the disc - very easy to achieve with a copier - discs after 2012 are NOT Jaguar sourced. On the other side sit those who have managed to source replacement DVD from internet auctions sites, claiming to be circa 2019 vintage, and have had no issues when loading these into the boot mounted DVD player. In essence, you pay your money and take your chances. Personally, I rely on alternative navigation devices now as the original discs are significantly out of date and next to useless. The alternative is to seek out a suitable automotive technology company who can install Apple CarPlay / Android Auto in a Modern XK - it is a little more involved / difficult in a 5.0 Litre car than the earlier 4.2 Litre cars.

Hi Garry, the back box is only a part of the entire exhaust system and the "drone" being experienced is the result of the entire exhaust system - the noise made by the system appears at the tailpipes - not in the middle. Accordingly, changing only the centre section to remove the silencers contained there, will change the entire exhaust note that emanates from the tail pipes. Changing the back box and leaving the centre section silencers in place will also change the exhaust note, but there is a chance that version will be too fruity - lots of pops and bangs on overrun. As intimated earlier, visit one of the performance exhaust websites and check out the videos, with sound, of there various exhaust upgrade options. N6 JMX

Incidentally, whilst neither of the 2 x garages in Banchory carry out the MoT, they do have an arrangement with the local station so they can organise that for you so it becomes a one stop shop for all aspects of what you need. N6 JMX

Hi Garry, an alternative would be to replace the centre section of the exhaust with one from Paramount Performance or Adamesh (think they both provide the same parts actually). These delete the centre silencers on the NA XK, making for a fruitier sound from the engine. Modifying / changing the back box is a bigger task and may give a note that is more irritating on a longer journey. If you visit the Paramount Performance website, they have videos, with sound, of some Jaguars with modified exhausts. N6 JMX

Hi Ava, happy to recommend both Framor on Tillybrake Road and RM Motor Repairs at the Burn o' Bennie Business Park. For Framor, call 01330 823884, probably Jenny will answer. Framor do have a website Car Servicing in Banchory : Framor Motors For RM Motor Repairs, call 01330 558118, ask for Reese. RM you will find on Facebook, not sure they yet have a website sorted. In some instances it is best to visit the shop and both will be happy to talk to you and understand your issues. Both are usually quite busy, hence the reasoning for offering both garages details.

If you purchase the replacement cable and undertake the task yourself, should be very inexpensive. N6 JMX

Replacing the bonnet release cable is a common maintenance issue on the X-type. Best to undertake the work before the cable gives up as releasing the bonnet after the cable has broken is quite involved / difficult. In addition, the existing cable can be used to thread the new cable into place. N6 JMX

Given your additional post regarding difficulty closing the bonnet on your car, may I suggest the red light and the bonnet not closing are linked issues! N6 JMX

The 2 lights you refer to seem to be indicators that there is a message which can be read in the message centre, immediately below. The amber light seems to be related to the fact it's cold outside, according to your message centre indication. The red light typically means that one or more doors / boot / bonnet are not closed properly. The following is from another forum: "You have a message centre, little LCD panel that displays mpg, miles, etc. just below the speedo? That red light is the message centre warning light. Does your message centre display a message / fault? There's a long list of faults that RED indicates, from door ajar to abandon vehicle and take cover! According to the Handbook there should be an associated message displayed on the LCD readout. The only REDs that do not have an associated message are: Restricted performance Security failed" Hope this helps. N6 JMX

Hi Garry, yes I can see the rear silencer, but there are also 2 x silencers at the mid section, which is not shown in your photo. One of the "tuning" options that folks choose is to replace the centre section of the exhaust with straight through pipes, i.e. removing the central silencers. This does have the effect of making the car sound rortier. Need to check that central silencer box is there. Failing that, then the last remaining option is that your SAM valves are stuck open, resulting in the pops and bangs on the overrun. These are just visible in your photo, ahead of the tail pipe, there is one on each side of the muffler. They are not serviceable, but a local mechanic might be able to check and try freeing them off. Don't have any other suggestions for now. N6 JMX
