My best advice here and based on practical and actual experience. Buy only genuine Jaguar OE spares when it comes down to any sensor, sender or electronic module. Ensure you only fit parts which have EXACTLY the same part number as the component that is fitted to your car. Also ensure when you order...

The first time I`ve heard of this fault, Steve.

As David says, not the right time of year to be doing this sort of work. Regret to say, I`d have shot the job out to my local indy! I`m getting too old for this type of caper!!

3.08v!? That is one dead battery!

To be reliable and have any chance of recharging, 11.5v is the lowest terminal voltage likely to achieve success. Anything less than 11.5v and I wouldn`t waste my time attempting a recharge. The battery is likely to constantly fail.

I`ve changed fob batteries without issue. A simple change and that`s been it. No reprogramming required.

It could well be that your new batteries are defective. Perhaps try batteries from an alternative source. Do check they are the correct voltage.

A non OE spec wheel, Steve. Check with your insurance company to make sure they will accept such a modification. Also check quality to ensure these after-market wheels conform to UK construction an use regs. After-market wheels are not always as well constructed as genuine OE products. I`m not conde...

Regular short runs whilst in long term storeage are to be avoided. For every cold start actioned, it takes thirty miles of road going use to burn off the harmful side effects of a cold start. ie oil contamination and moisture content. Best to store a car with fresh oil and preferably change again wh...

Glad to see you here with us, Keith.

Enjoy your XJR.

Stu, First thing is to establish the true voltage of your battery. You need to use a multi-meter set to "volts, DC" on the battery terminals. 12.0v or less points to a fully discharged battery. 12.4v equates to a half discharged battery and 12.8v or slightly above indicates a battery that has suffic...

A blocked matrix is likely to be caused by internal coolant system corrosion, the bi-product being sludge which blocks coolant system components. Its the same in a home central heating system where sludge can bring the system to its knees. How do I know? Well, I had the heating man in to deal with a...

K&N agents in the UK sell uprate inuction system parts for the Jaguar V8 engine. I have a K&N panel filter fitted to my 4.2 V8 and previous to that, a similar unit on my S-type V8. Personally, I would avoid a cone type filter unless you put it in a box and continue to draw cold air from outside the ...

I agree with Steve. I`ve never had a temperature sensor last more than 80k miles! Change at each and every 80k interval and at least you keep a suspect and somewhat limited lifed part out of the failure frame. Thermostats can go on rather longer but seemingly even reliable items wil become erratic a...

Peter Sellars had a suspension knock on his new Rolls Royce which he bought as a Christmas present for himself. He drove it arund on Christmas Eve but the problem persisted. Come 03.00am on Christmas Day and being unable to sleep due to the irritation, he rang Spike. Spike wasn`t amused at being wok...

"Filled for life" . was the marketing hipe at the time was in the sales pitch. Sealed, the gearbox is not. Tricky to fill and vital to get done at the right temperature it is. Members and other users at the time the car was current would suffer frequent transmission failures because the 60k oil serv...

Sam, Go to the S-type suspension section on this site. I`ve a load of posts on the subject of repairing S-type and X350 suspensions. Most of my posts have images taken during overhaul. "Click-clack" is usually the vertical links from lower wishbones to the anti-roll bar. Cut them off with a hack saw...

The same on my old V8 S-stype and later on my XJR350. Both temp sensors failed at around 80k miles. The same and other symptoms as you describe. A duff sensor causes fault codes, difficult cold starts, an erratic temp guage and poor general running. Mixture control goes out of the window...... £8 or...
