It pleases me great to share that since last week I am the (very) proud owner of #28 of the last 100 S3 VandenPlas V12s from 1992. Yes, this last line produced for the Canadian market. Full with a commemorative plate and all.
The cat is exceptional. In her lifetime, she has been driven, and driven some more, well-maintained, and always garaged. The result is stunning: original body and paint in close to mint condition (Black Cherry), and better interior condition than my like-new 2001 VdP. Even the switches are still crisp. And the driving is very tight, solid, and robust. No clunks, no rattles, not an inkling of shimmer.
The infamous V12 yielded a wonderful ~205 ±10 compression on all 12 cylinders in yesterday's check (followed by new plugs), it sat through Friday rush hour traffic for 2hrs with no signs of overheating, the transmission is smooth and brisk. She's very quiet and eager at once - I'm sure you all know the feeling.
She'd been mostly sitting for awhile (about 6-12 months), so I'm going through all the checks and corrections, a full tune-up, fluids and filters change.
My main concern is the non-op speedo/odometer. The connections in the back are perfectly fine, so I'm wondering if the problem originates in the source. My question is: does the speedo get its reading from the infamous transducer in the transmission, or did this change with ABS-fitted models? Meaning, are there speed sensors, or the like? And the transducer, where do I find it?
I will update here with more news as I investigate, but any ideas and pointers are very welcome. I also will post some pictures once I get the chance to get some good ones.
The speedometer receives its signal from the transducer attached to the gearbox. Check the electrical connection from the transducer to the wiring loom for corrosion.
Part number is DAC4569 should it prove to be faulty.
Quite a few items rely on getting info from the transducer. Cruise control, interval counter, trip computer, interface unit and speedo functions. You can trace the related circuits using publication S 57 (fig 18.1)readily available everywhere.
FYI the V12 XJS switched from the gearbox speed pickup to one on the differential which connects to a Speed Interface in the truck. I think this was in '88 or '89 model year so it's possible that a similar switch was introduced in the late V12 Series III cars.

Good thought, but, no, the V12 Series IIIs never used the diff mounted speedo sensor/transducer.
The XJS switched to the diff mounted speedo sender at (something like) VIN 144xxx which was roughly mid-1987 calendar year.
what a great find. I would absolutely love to see this car come down to San Jose!
you have two fellow forum members that would die to see one of the last series 3's.
post some pics.

Thank you, NBCat, and thank you JagCad - will be going down and under this week. Thankfully, the part doesn't look prohibitively expensive if it comes down to replacing.
Also, yes, indeed, this cat has ABS, the servo is on the RH (passenger) side. Ergo, it must have speed sensors on the front wheels and/or differential, I'm thinking.
smgdata, thanks for the invitation. I will, of course, come down to meet you guys. I just need to do a couple of things before: she has an exhaust leak that I want to address (hopefully this week), and I may be removing the fuel rail to do some preventative checks and cleaning on the injectors. Plus giving the vee a good clean.
I used to own this car. We should talk! But yes, the V12 VDP is a superb machine and that engine can give you 24 mpg on the highway quite easily.
The problem with the speedometer is indeed the transducer which is easily replaced.
You will love this car but owning a V12 Jaguar can spoil you for anything else.

Bloody hell! I suspected in the back of my head that I might bump into a PO, given the numbered edition - but I didn't anticipate it'd happen so quickly. Yes, please, let's chat whenever you feel like.
Small world, indeed, I wondered if it just might be Dr. Gregory's car.
The "black cherry' description lit up my imagination.
Fortune, indeed, that car has received care rivaled by none.
Mac:
No reason why it can not be CA registered. Paul Novak has a sister car. He is in SOCAL.
My vague understanding of ABS is that each wheel must have a sensor?
Some time ago, l farmed out changing a bent axle and busted wheel bearings on the rear of my 94 Jeep. The shop had a time finding n axle with the disc for sensing speed. Just a tad different to drive than my non ABS Jaguar.
Yes, JagCad, I know. I'm simply fighting the Year/Make/Model greeting battle. Do I say 1986 XJ12, or 1992 XJ6 to get part numbers?
Ha. First world problems.
Anyway, I might need to replace the rear cats - the ones currently on are nondescript so I'm looking at alternatives. Of course, the ideal would be eradicating them altogether, but that's not going to work for now in CA.
Did the oil change today, this weekend I'll continue with more tune-up, vacuum hose replenishment.
Whilst up for the oil/filter change I tinkered with the transducer (which, by the way, I found to be on the LH/driver's side): no luck. Will be ordering a new one tomorrow.
You NEVER reference a 1992 xj6 for parts in the US - they have no listings at all for this car - the 1992 xj6 is an entirely different car. For mechanical parts in the US for this Canadian-market car you reference a 1988 XJS - that is, pre-Marelli ignition. In 95% of instances this will give you the correct part. For body and trim parts you reference the 1986 XJ6. For anything else, ask me.
And, yes, as stated, the Jaguar 6 or 12 sedans and XJS coupes and convertibles shared a lot of things.
And, Jaguar like most other car makers out sourced many parts.
Those parts used by others as well. often, buying as another make
means a big price difference as well as expanding the sources.
Catalyctic converters in CA. are an issue. They must be
CARB approved. Read as cost more than others that might be just as good or even better.
Dear friends, since your invaluable contributions here, I replaced the transducer, did a thorough tune up (injector harness, connectors, injectors, injector and rail hoses, wires, filters, belts, oil, and basically everything that I found in need of replenishment), new cats, mufflers - the lot.
At the same time, however, life had its own plans: come September, my wife and I are moving to London where she will work for the next couple of years (she is a concert cellist). I was faced with two options: shipping the Jag to the UK, which is a complicated, and expensive affair, or selling her (I'm keeping my 2001 VdP for now as my daily driver).
With a heavy heart, I decided to do the prudent thing: sell her. So, I'll be putting her up on the JCNA forum, and I'm also letting you all people here that she is up for the taking.
You all appreciate the importance of parentage, seeing her go to a good home, so I need say no more. I'm not set on the price yet and I'm seeking advice on that, as I'm too involved to be objective. She is a wonderful ride and in excellent condition throughout. Two caveats: she's at ~155,000 miles (accurate reading is 246,700 Kms), and there's no paper trail.
She's located in Berkeley, CA, smogged, cleanly titled and registered till January 2017, and ready to be driven.
New 1992 VandenPlas S3 V12 - but speedo??
