    My cranking battery is about 18 months old, Varta from battery world. Wondering if changing that is an idea anyhow?

    It’s not showing any issues with the Bluetooth bm2 sensor though.

    I’ve booked back in with Concord LR on Wednesday and back with Adventure Merchants to get my driving lights fitted plus the loose ABG 25 connector from the weekend. Decided against DIY on that.

    One way or other the rogue earth connector is going to be found out.
    Son had a Varta in a Golf GTI..just changed it after @ 2 years. Agent said that's about right. It still cranks his dunnydore fine but as agent said..ecu mod cars won't tolerate failing batteries. I'd put it on charge and load test it.. or replace it...not with Varta tho ..our run on these was not good.

    All good since yesterday morning thankfully. Decided to go camping anyhow as this was our “shakedown” trip.

    Today’s battery reading from the cranking battery - 3 hour drive to camp yesterday then evening running of fridge, 3 LED strips then overnight fridge use. Started fine, I used to get battery low messages all the time around the local area and also last time camping with the “old” yellowtop which we’d had for 6 years.

    It’s gone from 12.2v this morning back to 12.8v after 60mins. Not having had the battery monitor app for long is the cranking voltage warning EPB Faultcode U0002 - pre-trip post major  service yellow dash alert perhaps linked to the fault codes??

    Was telling my other half about bring some heavy duty cable cutters just in case. That would be less drastic, a bit of tape. Be fun having to chock the car all the time.

    My indy mechanic has told me that the "pawl" or what ever its called in the transmission that stops it going round and round is very strong in the D4 and is an effective "brake". He told me not to use the EPB at all. I don't, unless on a steep slope. Mind you, maintenance, as suggested, is the best option.

    On later D4s it will engage regardless. Once you shut down.

    I really hate that EPB. It seized on once when the module went and had to be trucked into the stealers for a complete overhaul. I hate the thing. But I'd rather use it than have the weight of the car on the transmission "pawls" or whatever they're called as I know 2 people who've had major probs. by being too lazy to use their handbrakes. Strangely (or maybe not) both drive (or did) Mercs.
    I never use the damn drive through function preferring to use it on/off myself but trust the mechanic to clean and adjust at service time therefore I don't use the stealers.

    Over the years I’ve had several vehicles with conventional hand brakes that seized on. Never had an issue with the EPB - because I service and adjust it as required.

    With all the tech in the D4, it’s still been the absolute epitome of reliable transport.

    And the added capability of that EPB when offroad is excellent. (Wonder how many are aware of those functions and use them?)

    Not a lot, I suspect.
    I, too, was sceptical of the EPB until I took the trouble to learn about it after being amazed at how it functioned in the bush, particularly how it operated in conjunction with the Hill Descent Control system when going up steep inclines. (I find HDC pointless for downhill as you have full control over gearing and brakes anyway. I switch it off going down and turn it on going up!).

    When replacing the battery, check the earth connections.
    Was any electrical work done at the last service? A simple loose earth may be causing your problems.
    The Varta is 18 months old, thinking of getting that tested today. If it’s got issues - warranty would just cover like for like? Got it from battery world. What would a dealer or Indy put in there instead?

    Re: The multiple earthing points - under the bonnet?
    Is there also one in the jack storage area?

    I’ve not touched either as electrics isn’t my thing but did have to wiggle the jack out as that was left in place when the drawers and slide was done.
