A very late update. the gearbox issue has disappeared after the oil top up and some subsequent use. The diagnostic Foxwell NT 530 does indeed access all the ECUs but it needs some special instructions to use it. These are not easily found , one does not follow the menus as presented. For the XJ 308:...

I have X308 that is driving me nuts on an emission issue. The Right hand bank (exhaust) reads perfectly within all emission specs but the left bank(exhaust) fails on all aspects. The Co is around 1.8%, lambda 9.67, HC 15%. Should be <0.5 % CO, >9.7 Lambda, HC <14% ?? I am using an Innovate 3000 MOT ...

Hi All, Having followed several E10 debates, and PODCASTs, from JEC, I feel the issue falls into two positions. 1. If one uses the car for a significant mileage, then avoid E10 in your classic. In preference use the ESSO supreme 99 but be aware, as from the recent JEC podcast that ESSO only distribu...

Hi All, I did load the latest firmware but to no avail. I gave up and further searching suggested that the Foxwell NT530 would do the job. I bought one but found similar issues. However, I have cracked the Foxwell NT530 diagnostic and yes it does read all the modules on my car. The missing bit is a ...

Hi Andy, Well progress. The CAT supplier is BM catalysts Mansfield Notts NG18 5DL. website :-https://www.bmcatalysts.co.uk/ I can also tell you that I have cracked the Foxwell NT530 diagnostic and yes it does read all the modules on my car. The missing bit is a set of instructions as to how to use i...

Hi Andy, Yes i too have the Torque app with the ELM327 connector and have found it to be very good for engine diagnosis and it still is. I also have a very early Auto Ingenuity package but the current package is rather expensive. Gendan no longer seem to stock it although it is on their website at £...

Hi, I don't have the supplier to hand but I think I have the Compliance certificates somewhere.... It was a company in Manchester. I'll see what I can find. As I remember it was not too bad to change them. The bolts holding the cat to the manifold were difficult. When I took the old cats, on seeing ...

Hi, I see there is much discussion about the cost of cat replacement. I needed to replace the cats on my 2001 X308 and after research found that non OEM cats were available much cheaper than the Jaguar parts. However I also found that there is a legal requirement that replacement cats for cars after...

Hi, I said I would update 10 months ago but it has been a rather unusual period. However, I have failed to identify the fault although now that the warmer weather is with us and I have needed to use the car more, the problem is hardly noticeable. I have been trying to find a diagnostic unit that wil...

The sounder on the X308 is difficult to find and diagnose as faulty. I found that the sounder is connected on pins 2 and 10 on the buff plug on the electronics module in the boot (trunk). The wires are colours red and blue One may check the sounder with an Ohm meter connected across the pins. It sho...

Thank you for your reply Peter. You have confirmed what I thought. I had written to icarsoft support to ask their confirmation and whether/how I could get the unit repaired. I was totally thrown when I got the reply which I quoted verbatim. Just a single sentence! I did reply to query the answer but...

Hi, I have been using an ELM327 bluetooth and Torque software to successfully decode engine warning issues but I want to monitor the transmission now. After researching, the Icarsoft i930 seemed to have the required functions. However having obtained one I cannot get it to usefully connect to the ca...

Hi Andy,, further to your question, I have tried waiting some minutes before driving off from cold and found that the change up seemed to work OK. It is of course considerably warmer weather which may have some influence. The following day I tried it again from cold but driving off straight away and...

Well it has taken some time but an update on the gear change failure until warm. I have followed the process in the link supplied , the box took a further litre of oil befor reaching the level. I used a infra red thermometer aimed at the gearbox sump. The problem still persists although I have found...

Thanks Andy that is exactly the info I needed. I do all the work myself after my main agent experiences. I have used the correct oil using a kit from Berkshire Jaguar who I use for most Jaguar parts. I have replaced the timing tension parts and chains, brake caliper, wheel bearings using parts from ...
