Service log 2010 – present


The 18. August 2011 at mileage 89.300 km the car passed inspection (MOT) without any remarks. Oil and water levels checked and found OK.

June 2012 PBV sells the car to AGR

The text from 2012-2016 below is translated, but otherwise left original with AGR as teller

New inexperienced Jaguar-owner – I wonder if I can live up to the car’s history?

I (AGR) bought this Jaguar XJ-S V12 June 2012. I may as well admit that I do not have experience owning a classic Jaguar or a classic car at all. I have always been fascinated by the Jaguar-XJ, and my father-in-law has always thought it was a bit of a pity that I did not have an XJ while I lived in England but instead spent the money on BMW’s.

It was a bit of an incident I ended up with an XJ-S. I was actually looking for on an American car like a late sixties Ford Mustang but by chance I was told that there was a Jaguar, I ought to see. I didn’t know that it was a XJ-S, but when I saw it, I was pretty impressed by the design and engine – and that way my slumbering Jaguar-fascination suddenly awakened again. I then went home and read up a bit on the XJ-S, which I never really had noticed in traffic, and I was not less interested after this.
Unfortunately, the XJ-S, I had looked at, was sold a few days before I called back to the seller, but I was “hooked” so I searched further for another and found the Jaguar XJ-S V12, which are presented on this web page.


The first few weeks of my ownership of this car I have driven about in the 700km, which includes 350km in order to get the car home after the purchase. This has went relatively smooth, except from that the ignition lock is broken. The small metalpiece driving the contact sets is broken. A new new ignition switch is ordered at Vintage Car Service and a mechanic friend has made a temporary solution making at possible to drive the car until the new ignition switch is mounted.

20.07.2012 90500km Faulty ignition switch replaced with new ignition switch from Vintage Car Service.
Created a drain hole in the bottom of the boot at the spare wheel and cleaned the drain tubes from the boot lid recess
21.07.2012 90500km 2 kg powder fire extinguisher mounted in the trunk.
28.07.2012 Front seats treated with leather soap.

The next project is the replacement of the two engine thermostats. One of these (or both) may be defective and the hope is that this will also improve the current somewhat odd function (or most often lack of function) of the air conditioner …

13.08.2012 90700km Replacing both thermostats in the engine (thermostats from Vintage Car Service).

Replacement of thermostates have immediately resulted in a hotter engine, but the needle comes still not quite up to “N”, however, further up than before. I’m assuming that the needle is calibrated on the basis of the original 88 degree thermostats, so the current 82-degree thermostats do not get the needle up on “N”, as it is described in this article from jag-lovers .

Today, the 2. September, I decided to pamper your car with some care products from It was a pleasure to wash the Jaguar and especially the wiping it with a large Microfiber towel after use of Hydro Shine was pretty nice. Also applying the Magic Dressing on the plastic parts (bumpers and tires) gave a good look, but the bumpers should probably have a couple more times to become saturated.

Some also suggest that a fuse is gone-the only problem is that I have measured the fuse and it works fine. The symptoms are that neither the blowers for the ventilation system, horn or sprinkler pump works and the systems are sitting all on the same fuse. Further debugging revealed, that it was a relay that was faulty. This relay is placed between ignition and fuse box and provides several circuits.

09.09.2012 90900km Replacement of defective relay between ignition and fuse box (sitting physically just above the fuse box)

Now have the car as just been in the workshop in order to get a little rust fixed as well as changed the spark plugs and oil, as well as regular maintenance. On the same occasion was gearbox suspension repaired, so now it runs like a dream. Except that it has begun refusing to start without notice, but I have to probably look at next spring, for now it must soon be parked for the winter.


I am participating with the Jaguar in Oldtimer race in Graasten in the end of May as well as the Englishman gathering in Løgumkloster in June.

The car was inspected (MOT) in august 2013. In the first place it was declined approval due to lack of lock seat lock belt when stationary.
I did however get this rectified later, since the seat belt type in this Jaguar does not have drag lock when stationary. In addition, small comments on oil spill at a rubber bootcuff, which was repaired immediately after the inspection

August 2013 92000km Repair of defective steering rack boot as well as adjustment of headlight


The first task for the Jaguar is driving with my son and partner to the high school Prom party at Sønderjyllandshallen in Aabenraa. We only just made it as a power steering oil hose started leaking. With a few refills on the way we managed. I ordered a new PS oil hose at Vintage Car Service and had it fitted at the local mechanic in Tinglev.

May 2014 93000km Replacement of power steering hose

Also in 2014, I participate with Jaguar in the Oldtimer race in Grasten in the end of May as well as the Englishman gathering in Løgumkloster in June.

I continue to enjoy this fine Jaguar product, but only until I notice dripping from the front. It turns out to be a leaking water pump. I went to see Jaguar specialist Karl-Heinz Kühn in Flensburg, who performed the repair as well as several others associated repairs, amongst other things repair of the radiator.

August 2014 93309km Replacing the water pump, radiator repair, as well as various other associated repairs

However, the joy is short again. Driving along I notice heavy smoking from the rear wheels. It turns out to be the rear brakes sticking. The rear brakes is replaced including new calipers at Jaguar specialist Karl-Heinz Kühn in Flensburg and there is again several associated repairs initiated by disturbing old parts.

October 2014 93500km Replacement of rear brake (complete) as well as various other consequential repairs.

New owners in 2016

28th April 2016 94805km Leo and Anne-Marie are the new owners of the car ! We saw and drove the car first time in October 2015. The car drove really well, but the amount of patina took some time to get used to. After looking at 5-6 other (and driving 1, as the rest was not running…), we decided this was the one.
13th May 2016 New wiper blades 15″. RH blade is too long, but that seems to be a common ‘feature’
Distributor cap removed and cleaned, free angular movement of the rotor checked and found OK. Spark plug leads cleaned.
A/C drive belt tigthened
Air cleaner boxes cleaned, air filter checked, found ok and rotated 180° to sit correctly with the closed steel backplate section facing the throttle body opening to prevent the engine from damaging the paper filter.
Front axle greased. Front brakes look fine, but bushings looks … old


18th May 2016 95250km The engine driven cooling fan was cracked. A new cooling fan EBC4553 from David Mannners mounted. Updated black design. The operation was possible, but not funny to do without removing radiator and fan shroud. I did not slide a piece of cardboard between radiator and fan, but that is recommended to protect the fragile structure of the radiator.
The fan clutch looks quite new, nice and clean. Water pump drive belt tightened.
23rd June 2016 95700km Left rear tyre and spare tyre exchanged. This results in 4 similar and not too old tyres on the car and the most ugly rim in the boot with an old tyre on it.

Investigation of the non-working climate control.

The air coming from the wents is cold and the fan speed can only be off or on max.
The vacuum operated heater valve placed centrally on the bulk head works fine, and warm water flow is present. The temperature sensor in the water line is also OK. This is important, as a defective sensor makes the control think the water is still cold and then waits for the water to heat up before starting the heater up.
The fan resistor pack was measured in situ (probably not possible to remove w/o dismantling a lot more) and found OK. The 4-relay unit removed and repaired. 2 hair wires were broken. After this the fan now has 2 speeds, but cannot be turned off anymore !
Discussion on forum concludes I need a new climate control. LINK

30th June 2016 95800km Rear axle greased. Wheel housing edges cleaned, inspected and covered in Dinitrol. Some rust found, small rust holes sealed for now with heavy dinitrol.
Alternator and servo pump belt tigthened, servo fluid topped up with Dexron II ATF.

3-4rd July 2016. Trip to Lüneburg to visit my brother and family. The car drives really well and returns an average consumption better than 8 km/l, and we didn’t drive particularly slow…

30-31st July 2016. Trip to Copenhagen Historical Grand Prix, where the car was on display at Jaguar Club of Denmarks exhibition. Again the car behaves well, but the aircon decides for the second time to actually kind of work. The last 50 km was therefore done with the heat on max and no option to turn it off. Open windows…

11th August 2016 Both windscreen wiper fitting pins exchanged with new DIY parts made in stainless steel after one pin broke during carwash…

21nd September 2016 97100km New climate control amplifier C45402. Climatron updated and refined digital control from an Australian Ebay-seller LINK
eating now works !

Winter 2016-2017

Mileage 97360. We are using the advantageous (read cheap…) Vintage Insurance, and that enforces no usage of the vehicle from November 15th to March 15th.
This allows for larger repairs, and this winter the ignition components has been replaced and the boot fuel smell issue has been solved  worked on.

AAV fixed using Grant Francis’ great instruction: AAV rebuild procedure

March 19th 2017. First drive of the year. The car started well and runs really smooth.

29th March 2017. 97500km. Door mirrors fixed: LINK

April 25th 2017. Stop light bulb failure module fails and causes the stop lights to fail (!). The unit is placed in the rear end of the centre console. Fixed by resoldering a broken wire –>

April-May 2017. We use the XJ-S for several long drives to Hamburg, Moesgaard, a confirmation drive and finally our son Jonas and his girlfriend borrows the car to drive to their prom night. We meet with them after they have arrived to the party. They hand over the keys, and then the car refuses completely to start. Zero reaction from the starter, so the drive home was on a flatbed transporter. It was lucky this didn’t happen when they were on their own in the car crossing through Odense…

The non-starting issue turned out to be lack of continuity in the circuit from starter relay through the switch in the gear selector. It was probably just the inhibitor switch that failed, but the quick solution was to give the starter relay a new ground through a parallel wire thereby cutting this safety switch out of the system. The starter relay is found on rear innner wing near the bulkhead.

August 1st 2017. 99.000 km. MOT passed with one minor error: Hazard warning lights doesn’t work. Registration changed to ‘Veteran’ with 8 year inspection schedule. I had the VIN corrected in the system as well as the old data included part of the body number as well.

November 15th 2017. 99894 km. Start of winter hibernation.

April 2018. 100000 km since the refurbishment in 1989 is passed, and the season starts with an oil + filter change and a new fuel pump to replace the original noisy pump. The new pump has different position of the outlet, and the new fit is not perfect. Needs to be repositioned next winter.

Later in April both electric windows fails to function. The cause turns out to be a broken wire in a relay placed in RH foot well.
I do a confirmation drive for a former collegue, so the car is once again polished and fettled for.

June 6th 2018, 00600 km. New Bosch fuel filter mounted, fuel line between fuel filter and first pressure regulator replaced. Fuel line routing improved (moved away from exhaust downpipes) and lines and filter is insulated with glass felt wrapping. The condensator in the ignition amplifier placed on LH inlet manifold is removed, as these are known to fail and cause ignition failures, and we are having exactly that: Misfire especially at high ambient temperature and at low load/low rpm

June 19th 2018. LH dash fan is removed and dismantled to find out why it is making noise. It turns out there is a lot of axial and radial play in the electric motor. By adding shims to take up most axial play the radial play is also reduced.
The fan is placed in the footwell. Remove knee bolster, disconnect battery. Next step is to get the bracket with fuses out of the way. It is mounted on 4 studs, where the upper left is close to impossible to access. The fan itself is fixed with 2 bolts. Once these are removed you force open the lower air flap. This causes the upper flap to close, and the fan can only be removed when the upper flap is closed. You will have to disconnect the power connection and a vacuum line as well to get the fan out.
Disassembly and assembly is pretty straight forward, more or less everything is just bolted together. I had 3mm axial play, which I reduced to 1mm. Noise gone !

July 27th 2018, 01400 km. Brake fluid change. DOT4, 0.5 liter used.

August 15th 2018. 01660 km. Aircon conversion from R12 to R134A finished. New condensor and filter/drier/receiver from FENair. Details here: AC conversion

August 21st 2018. 01700 km. Viscous fan hub (NBC2215AA) changed. The old hub had less resistance against rotation when warm, and compared to the new hub the resistance was also lower when cold.
Simple comparison test: Clamping the hub flange and giving the hub a good flick: Old hub takes 4 flicks to do a full turn, while the new takes 6 flicks. Both cold.
The professional test method can be found here: PDF
Tip: The hub can be changed without removing the fan itself. The ends of the threded studs on the drive is very close to the clutch when assembled. Due to this the nuts must be removed and mounted in steps. Mounting one nut too far will prevent mounting of the remaning nuts.

August 21st 2018. 01700 km. The original Lucas TPS (throttle position sensor) dated 2788 is replaced due to low throttle running issues. The TPS is a simple potentiometer with 90° operation angle delivering a fraction of 0-5V increasing with throttle opening to the ECU as throttle position feedback.
In case of dropouts in TPS signal the ECU will not know the correct throttle opening and fuel injection pulse length will therefore be wrong. Output voltage of the TPS adjusted to 0,324V (must be 0,32V±0,02V). This was another point, that could cause the rough running at light throttle, but the new part didn’t change anything.
