Battery died after MOT from Jaguar

[Jackle14]

Hello everyone,

Last year when I had my MOT for my F-Type (my16) - it developed. “Please start engine low battery” when powering off. The Jaguar garage took car of this promptly and told me it was their issue.

Fast forward to the 09/09/24 and I have my MOT done.
The day later I have the same issue. I call them and they are very dismissive this time and had me booked in earliest 31/10/24.
I complained several times for my car to be seen asap but they never called me back.

Fast forward to Sunday and my car is as dead as a dodo. It won’t even open the door properly due to no residual power.

I had to physically turn up to the dealership this morning to be fobbed off by the manager claiming that the battery is my fault and they “Don’t use the equipment anymore to leave the session open” so the drain is not their cause.

I told them I know it’s their cause because it’s not coincidence that this happened directly after mot for the second time.

They are recovering the car tomorrow at my own cost and exclaimed they won’t be working on the car for weeks now due to a backlog they have.

Is there ANYWAY I can prove they’ve left the session open? I have a horrible feeling they know they’ve done this despite “changing equipment “ and will blame me/my battery for the fault.

I’m absolutely livid with the way they have treated me and I have complained to Jaguar customer care and they didn’t get very far when they phoned the dealer either.
Awful customer service…

Please can anyone advise how I can not be lied to when they eventually look at the car?

Kind regards,
Kyle

Tis the season for battery related issues.

If the battery is completely flat then I guess little options exist unless there is enough charge to lock it and see if hazard warning light goes out or not.

I don't see the point of paying for recovery to garage that is being unhelpful and won't look at it for weeks. Do you have breakdown cover? Do you have the means to charge the battery? Or for the cost of recovery and Jaguar looking at it, then a new battery will probably be cheaper and a lot quicker!

If it’s just a battery issue and that’s what it sounds like.. Just cancel their recovery, call your breakdown service (assuming you have home start?) They will fit a new battery. Alternatively use likes of Halfords mobile service to bring a battery out to you, or best and most economical option buy a replacement and fit it yourself.

Thanks guys -

@mikeM - replacement battery easy? I always thought this was complicated due to needing to have it talk to ecu for stop/start etc or am I being dumb? (My knowledge is low)

If I did get it replaced - would the phantom drain issue they caused with the open session after odb port mot - wouldn’t it happen again?

Cheers

Disconnecting the battery for about 2 min will reset the OBD port.

Why not take it to a decent place to get the MOT done, which doesn't require anything plugged into the OBD port?

And I doubt the battery needs to be replaced, just get a CTEK (or similar) battery maintainer, give it a good charge and recon and you're done!

If disconnecting/reconnecting doesn't work and you don't have breakdown cover, you could take the battery out and down to your local Halfords who will check it free of charge.

It'll tell you if the battery is expiring and needs replacing - if so, problem solved. On the other hand, if you get a good reading take a photo of the screen and you have some leverage if you need to progress things with the dealer.

Being made to wait a month in the circumstances you describe isn't good and I'd be voting with my feet, personally. From what you've said, it doesn't sound like they'll take any accountability even if they have dropped a knacker.

 

[Jackle14]

I’ll try the above guys - cheers.

Problem is though - the car is completely dead - no life - so the boot won’t open and I am guessing I need a jump start to try and get that open to access the battery?

If it’s in this state (no life) surely the battery is now gone?

Lots of good advice here, most importantly “Cancel the dealer pick up” Changing the battery is straightforward and as already stated just disconnecting for 2 minutes will reset OBD port. The battery may be okay and just need recharging although if it’s the original possibly on its way out. Do you have home start cover? If so just call them they will jump start it from the engine compartment connection and can diagnose from there.

If you haven't breakdown cover, have you a mate with a set of jump leads? That at least would allow you to access the battery and proceed as above, ie. charge the battery, disconnect it for about a minute, then reconnect. Hopefully that should solve the issue.

You can open the car using the physical key located in the fob. Once in you can pop the bonnet and connect power (spare battery or a real charger (not a maintainer)) to the underbonnet terminals. Have the fob handy to stop the alarm! That should give you enough power to open the boot. I had a flat battery a few months after I bought mine and the AA (Jag Assist) came out and got me open and going. I charged my battery with a CTEK and the recon option and that battery is now over 7 years old and still going strong (hope I haven#t jinxed it!). I still pop the CTEK on it every month or so to keep it topped up.

If you do remove the battery make sure you put someting over the boot catch to prevent it from closing, or you'll be in a world of pain to get it open again!

Thanks everyone!!

AA have checked the battery and it’s all good so far - it’s now running idle for a further 2hrs to see if it’s all good.

Only £35 - happy days (yes the battery got charged enough and then disconnected for 5mins to reset odb)

If the battery went flat that would be the equivalent of disconnecting to reset everything anyway so no real need to do it manually. I would suggest you get a battery maintainer if you haven't already, so you can fully charge the battery and don't suffer this again.

Or get on Amazon or similar and buy one of those lithium jump packs - they normally have a "boost" button which when connected to the jump points under the bonnet will give you enough power for a brief time to unlatch the boot. I've used one a few times when the battery was flat, to access to charge it.

My car isn’t used so much in the Autumn and Winter so is permanently connected to a CTEK MXS5.0. also have a Noco GB40 for a rapid jump start but this is usually used to support someone else’s car

I had this issue and the battery was replaced free of charge under my extended warranty.

I had my local independent garage (an independent Audi specialist I use for my wife’s S4, but also happy to do bits n pieces on the F-Type when needed) do my battery, which was causing the same issue that you describe. They fitted a new Lucas brand battery and did the ECU reprogram to “tell it” there was a new battery. Excellent job and they fitted it in next day for me and I’m sure at a fraction of the price that you’ll pay for the dealership recovery, etc.
