HI. My temperature gauge in dash does not register unless I am in heavy traffic: motorway cruising and it stays at bottom of dial. I think its the sensor either stuck or broke and for the price of another on I want to replace it: however asking how easy or difficult that is in terms of access from the top of the engine? Thanks

Hi - I've seen this fault discussed a lot under x250 motors but not x260 as the design of the routes for the wiring is different. My car is showing the boot lid as not shut when it is and I believe its a wire fault in the loom - however I cannot find a supplier for a new loom - not sure I want to get into ebay unless necessary. Could anyone point to a supplier or got a solution by experience? Thanks

finally sorted it, and it was such a simple fix, if anyone experiences this problem here are the simple steps to fix the issue, 1. open boot and disconnect the neg (-) terminal 2. leave disconnected for 5 minuets 3. touch the negative (-) lead to the positive (+) and hold it there for 30 seconds. 4. close boot lid manually. 5. press and hold pan roof open button. you may also have to reset the handbrake by holding down the foot brake and applying the handbrake.  after doing this mine is all working fine even on the remote fob. hope this might help anyone else with the same issue i had. 

You're welcome - as an afterthought, if it's not sensing the CKP, it could be the other sensor is doing what it should but as there's an incorrect signal from the CKP, it reads the other one as faulty too. I'd do a reset after fitting the CKP and see what you've got.

Welcome aboard and GLWTS - always wanted an XJ-S of that age and it has the twin headlamp conversion i've always preferred. Sadly i recently splashed out on something for practical purposes rather than an "occasional" car or i'd be biting your had off - i'm sure someone else will feel like i do so i doubt it'll hang around for long!
