      Thanks Laurence!

      Have you experienced (or heard of) a ‘singing’ noise in other XJ-S cars, and how the issue was resolved ?

      My 2005 S-Type has a sealed-for-life diff, the oil level and quality is ok I’ve been told by my mechanic. However, its diff has a similar problem, which a Jaguar-approved service facility in Benidorm is now going to fix. The diff itself will be taken out and sent to Valencia to be repaired. They told me it’s a Ford unit, not strange since many components are Ford in these cars. The repair cost is about 1000 euros, a new one from the factory 4-5 times more.

        Oh, I forgot to say that I’ve had the wheel bearings checked by a Jag specialist, and he found nothing wrong.  So the ‘song’ evidently doesn’t come from the wheels. He also checked the level of the diff oil, and said it was OK. However, I don’t  think he tested the oil to find out if it was a proper LSD-oil.

          Hi David !
          Thank you very much, this was very helpful! I will try to open up as described. Hopefully the rod will not be broken, but merely somehow disconnected, or it could be a broken spring. First, however, I will try a suitable spray to find out if the mechanism is just stuck a little (always an optimist).

            Hi!
            I didn’t know that the latest Cabriolets had ABS. However, I do know that a Norwegian-registered Cabriolet (VIN 146690), supplied new to a client in Oslo, Norway in January 1988, probably the last cabriolet supplied new to Norway, did have the later Convertible style seats, steering wheel and Lattice rims. According to what has been mentioned above it would seem this particular car did not have ABS.

              Hi Laurence!

              I first didn’t think my car had the elusive number, but after a thorough check I found three digits, i.e. 620, barely visible under the new resto paint from 2013. I’ve tried to take several photos as proof, but none of them are convincing. Unless later photography will give better photos, you’ll just have to take my word for it, or better yet come to Spain to see for yourselves 🙂

                Hi Norman!
                Thanks for your reply. I’ve thought the same, but I’ll still check if SNG Barratt have got new senders in stock. I understand the tank, inc the sender unit, is easily accessible behind the spare wheel and some bracing.

                In my case the dash warning light seems to light up long after the gauge shows ’empty’. Somehow they don’t seem to be synchronized, which is good under the circumstances I guess. Is it the same with yours?

                  Hi! My ECU was repaired and upgraded by AJ6 Engineering. My 1985 3.6 ran too rich and soot tended to build up somewhat over time. This was visible on the plugs and on the very ends of the exhaust tail pipes. The fuel consumption was also a bit high. After the ‘operation’ no soot builds up, the plugs are clean as are the pipes. However, I still need to adjust something, but don’t know exactly what. The car runs perfect over 2000 rpms on the highway, but a little uneven when going down a hill or around town at low rpms. I will check the ignition timing, the throttle potentiometer, the fuel pressure valve and maybe also other relevant parts. Does someone else with a 3.6 have any input ?

                    Hi everybody, esp those interested in wind deflectors on XJ-SC cars!
                    I bought my first XJ-SC brand new in Portland, Oregon in August 1988. It came with a hardtop and wind deflector as standard equipment. It also had a rear soft top. I was told by the Jaguar Dealer (also a Rolls-Royce and SAAB dealer) that the hardtop and wind deflector were standard equipment in the US and had been so for quite a while.

                    Bleasie says the deflector is as useful as an ashtray on a motorbike, i.e. useless. That’s not true, it works quite well, at least with the hardtop in place and roof panels (of course) removed, as Bryan Thomas claims. The deflector is less useful with the rear soft top in place. The original deflector is removable, but I used to have it permanently in place, either folded up (panels out) or down/flat (panels on). My present European spec XJ-SC 3.6 TWR has neither a hardtop nor a deflector.

                    I will check if it has the holder (for the deflector) in place, possibly as an add-on to the panel locking device.
