Hi

I've had my stype 2.7 deisel just over a week. 2005 on a 54 plate.

I usually cycle to work as it's just 2 miles, but the Jag is too tempting and I've been driving since I got her. She's had one good motorway run.

Sometimes on turnover I get an abs warning on the dash. It just flashes up until the engine is running, never to be seen again.

I've just checked the battery, which has jaguar written on it so I guess it's original. Reads 12.11 volts

Should I change it?

Thanks

Rob

 

If you're still on the original battery, as in it's 12 years old, then that's nothing short of a miracle...

12.11 volts is low



Yeah you should think about changing it.

If the voltage drops too low while cranking the engine, it's pretty normal to see Abs Fault or DSC not available flash up on the dash while cranking, it's a sign that the battery is low, probably on the way out.

 

Thank you. I thought as much. I'll cycle tomorrow and order a battery.

Which one? Buy a Cheap Jaguar/Daimler S Type 2.7 Diesel 2004 - 2008 Car Battery Online - Alpha Batteries

Thanks again!

I've thrown two Jaguar batteries away over the last few months,granted one was the shape of a melon due to an overcharging alternator. If your battery is the original one then it's nearly 12 years old so could be past its' prime. I'm no expert but I would guess only doing a couple of miles twice a day isn't going to replenish the battery to a decent level. Most good local garages can do a health check on the battery, might be worth the small investment in a new battery anyway. According to www 12.6 or above is the norm for a fully charged battery and 13.7 to 14.7 when the car is running,although I'm sure there are other figures bandied about,sounds about right though. Like I said, not an expert, just my thoughts and a quick look on the net.

 

We have on another forum a person who has done a lot research on batteries. Even when you buy a new battery you will have to charge it because it will contain cadmium. These batteries need a higher charging rate of 14 volts and our cars only supply this for 5 mins. This means that over time you discharge the battery even when you do long journeys especially if you use the lights.
As you only do 2 miles this will be the case.

To check the battery charge it over night and then turn the lights on for 3 mins and then check the voltage using a volt meter if it lower than 12.6 then you will need a new one.

Another that you should be careful of is the of the dpf because you will not be getting it warm enough and you could eventually wreck your engine. Google it to find out about it.

 

Thanks. It's pre dpf so that should be fine.

 

At first I thought this would be an argument for having a battery tender but if the battery even looses charge while driving, specially with the lights on, there seems to only one solution. Get a new battery if very much below 12.6 V and certainly if around 12 V. Correct? Or am I reading too much into this.

 

I bought a new battery today. Can't be bothered with the risk for the cost of the battery.

Now if I could just get the frigging bolt out it would be sorted

 

What bolt? Got a photo of that?

 

the long one that holds the battery in place, it goes through the floor.

it done now.
