Hi new to this site and need some advice
I have a 2005 s type 2.7 d it is throwing up loads of fault codes egr turbo drivers door module abs some are showing low voltage before I spend loads of money just want some advice as I have read a lot of posts on low battery I checked the battery after leaving the car all night and it's showing 12.2 volts with the boot light on yesterday it was showing 12.4 after running around most of the day just wondering if this voltage is to low shows 14,5 with engine running cheers

 

Nooooo.....the battery voltage is too low.
Jags are notoriously fickle on battery voltage. You should be reading 12.6v after standing overnight, anything lower stands the chance it'll throw a code or EML
Plus if you only use it for short journeys that'll not charge it enough to maintain the systems requirements.
You could try putting it on a battery tender overnight, clear the fault codes, check the voltage in the morning to make sure it is up around 12.6v, then have a run around for an hour or two. See if the fault codes re-appear. But I suspect not.
And as you say in your post, if you have run around most of the day and it is showing 12.4 volts, then I would supect that it has a dying cell in it anyway.
Another case of a bad battery causing undue mayhem for Karl

 

Cheers Karl it does show restricted performance now and again so I'll do what you suggest and see what occurs

 

I would agree a new battery is the way forward.
As mentioned you may well find the faults disappear.
Mellow

 

Thanks for the advice guys had the battery checked at local workshop they said battery running at 48% they can't change it need to take it to a jaguar garage I phoned them and they quoted me £165 for the battery and £180 to fit it bugger that local independent £150 all in cheers Chris

 

More than you ever wanted to know about batteries here:

Please note a new battery is not a guaranteed fix, but if the condition is suspect, it's worth a gamble. Per the scorecard so far, the odds are about 50%. That may seem low, but is actually quite high for a single component causing otherwise unexplainable problems.

Also make sure to rule out other factors causing low pre-start voltage. It sounds like your alternator is charging okay, but you could still have a low usage driving pattern or battery drain that is complicating things. For troubleshooting, you can hook up a charger every night for a week so you'd know the battery is fully topped off at the start of each day. If the car now behaves itself, you'd know the issue were caused by low pre-start voltage.

 

180 pounds just for labor? Oy vey, that's spendy.

You'll need to do the throttle calibration:

Also, if you have the factory radio, I think it will require a security code. Most markets don't require it, but I think the UK models do.

 

Hi yes very pricey bloody rip off over here it's booked in for next week at independent jag specialist £150 fitted and calibrated the radio is coded I have the codes so should be OK thanks for your time I have downloaded the info you sent me gives me something to read later on cheers Chris

 

Can't you get Halfords or Kwikfit or somebody to do it? Oops I see you have!!

£150 still makes the eyes water.

 

A hundred and eighty quid to fit a battery? Find a different garage, or just go to Halford's or another parts house, purchase the battery and fit it yourself. It should take you roughly ten minutes.

 

Not Halfords they buggered up my son in laws Seat putting a battery on it I wouldn't trust them with my jag I don't think quik fit will be much better most of their blokes can't string 2 words together tbh

 

 

Ha I remember that advert years old they where half decent then these days their all called Dale and their vocabulary is limited "Der yeah mate tyres ****ed innit"
