Hi,

 

I thought I would ask some of the people who are unbiased and might know the answer. My Jag engine waring light came on. After taking to a local garage they told me I needed to replace the cats. However, when I got home the engine waring light went out and the car drove perfectly. It does so even when the warnignlight is on. The engine warning light came back on, so I took it to my local Jaguar dealer and they told me the same that I needed to replace the catalitic converters.

 

That was a month ago and today I went shopping and when I retruned to the car and started it the engine warining light had gone out. Additonal fact sometimes the airbag warning light flashes and then stays on but on next operation the light stays off. I believe I have a wiring problem not a catalytic converter probelm. Has anyoner else experienced this type of situation.

 

The reason I ask is that it is a very expensive fix to change the cats, especially if that is not the problem. The car has only done 69,000 miles.

 

Regards

 

Jim

hi jim

        do you have a code reader by any chance  

regards Ron 

Ron,

 

I do not have a code reader, the car is a 2005 55 plate 4.2 supercharged XJ.

you may want to get one Jim did they give  you have the code numbers 

 

if not mate you need to find someone to plug a reader into the car and get the codes off your cars system

Ron,

 

Unfortunately, neither place I took the car chose to provide that information to me, only the fact that, in their words, I needed to replace the cats, and in one case, the lamda sensors as well. That was not the Jag dealer.

not being funny jim i would invest in a reader  ive just brought one off ebay just a cheap one for £12.50 as i had egr problems with mine and it read the cars dtc's with no problem,gave me the codes & what the problem was & even reset / deleted them it after.

saved me loads of money first time out of the box 

ron 

Ron,

 

I did not realise they could be that sort of price, I will see if I can get one.

 

Regards

Dont get me wrong you can spend hundreds on one but for the DIY'ER i think a cheap or med range one is just as good 

 

the plug & play version are ok for what i needed, you may have to set it up but that takes all of 2 mins and away you go.

there's loads of after market ones jim just make sure you get it right for your car.

 

 MS 309 £12.45p free p+p  is the the one i got for my x type diesel 2009, not 100% sure if this one will suit yours but loads out there

ron  

Thanks Ron, I will take a look and hopefully they will have one for mine.

hi Jim

        your find one no problem a lot of them are multi  make & model units, so the hard bit is choosing which one
