Cloudy plastic headlamps didn't happen on my previous X350 XJ but I have this on my current X350. However this is definitely preferable to earlier XJs I've owned where one stone hit and the glass is gone, with a bill for a few hundred pounds for a whole new headlamp. I guess it all depends on the mi...

Hi Peter, glad to help. If you had owned old British motorcycles in your youth (and as I still do) you would be all too familiar with banjo bolts and also Dowty washers to upgrade from original fibre washers!

Hi, Contact www.sngbarratt.com and enter part number C2C30081 in the search box. The ones you want are the aftermarket ones they offer, not the rip-off Jaguar ones, which are special order anyway. Theses are in stock at £6.73 each incl.VAT. Shipping is extra. (Recently fitted a set of these on my X3...

Banjo Bolts: when you get one undone you will see that the underside of the banjo head has a machined circular rebate. This allows oil to flow from the attached pipe on the banjo around the bolt until it finds wherever the hole in the bolt has finished up. The oil then flows down the hole in the bol...

David, An update on my aircon compressor noise: it might be worth getting your system gas pressure checked if it's not been done in, say, the last two years. Here's why........ This week I finally got fed up with the compressor noise and aircon getting worse so had the car booked in for a check by m...

Have you checked that the ride height sensors are firmly mounted on the brackets and that the brackets are also firmly attached? Other that that the only other thing I can think of is an intermittent fault in the distribution valve block.

The air conditioning compressor bearings is a candidate. Mine, at 144k miles, is making a grumbling noise and varies with engine rpm (stops if you turn the AC off) so it's on borrowed time. The noise is quite audible in the car but can't be heard outside. Other candidates include the serpentine belt...

David, I suspect from your description of symptoms that the problem of the "sensors" relates to the throttle position potentiometers becoming worn. Remembering a Rover V8 EFi that I owned which had a worn position potentiometer, the hunting and high idle symptoms are similar, but with the then unsop...

Jim, I was not suggesting that the Dunlop Maxx were "development" tyres for the X356 but I prefer them to the original fit Pirelli P-Zeroes (mine are 255/40 R19), which I could never find in J-Spec and dislike P-Zeroes anyway for a variety of reasons. I have seen other makes of tyre stating J Spec, ...

Doug, Anything reading RED is out of spec and needs attention. Your nearside front Caster reading suggests to me that the suspension may have had a bash and knocked it rearwards, e.g. pothole damage. It could be within adjustable range, but may indicate damaged parts needing replacement are required...

"Replacement rears, Dunlop SP Sport Maxx in J spec were ordered for fitting by my local garage....." Jim, I have been happily running Dunlop Sport Max tyres on my X356 XJ8 for some years since they first came out. I tend to buy these online from companies such as Black Circles etc. or at a reasonabl...

That sounds like a sticking brake caliper. I had the nearside front one go last year; on short trips it proved no problem, more than about 5 miles it would make a groaning noise at low speed and if driven further it would start to pull the steering to the left. If allowed to cool down it became OK a...

That's very annoying for your friend but how did he let the battery voltage get so low? If he did not use the car very often surely he should have used a maintenance charger to keep it in good condition? I must say my experience with Bosch Silver Star batteries has been quite uneventful. The one in ...

I would not recommend just topping it up. At 100K miles and my car then still serviced by a main dealer, their reaction to my request to change it was met with surprise and is not a scheduled service interval item, because like the ZF auto gearbox myth "it's filled for life sir". They would normally...

On the X350 at least, these three faults will show up as a group if you have a faulty wheel speed sensor. I've had this happen 3 times now and had to change the faulty sensor flagged by the diagnostics. After changing the sensor and resetting the codes everything works as normal. The rear sensors ar...
