battery drain

I seem to have a battery drain on my 2016 T6 150 highline as it struggles or fails to start after about 6-7 of not being used. Firstly I believed it to be the battery, so had a brand new AGM battery installed and coded to the van but again after 6-7 days I’m getting the same issue. It appears to...

Hi all - looking for some help please. 2018 2.0 TDCI T6 - Leave the van for a few days and the battery is duff. VW have already changed the battery under warranty so its not a dead battery. Something is causing a drain. What is the best way to see what is causing the problem? Can you speed it...

Does anyone have a picture of the inside roof panel of a factory LWB Kombi that shows exactly where the two original interior lights are in the roof? My van had LED spotlights installed when I purchased it that aren't connected in any way to the standard interior lighting circuit. I cannot find...

Hi, I'm at a loss, I've had a new starter and leisure battery installed in the past year and have a B2B Victron Smart Charger, which should be set-up correctly, but I've left my van for a week to find that the starter battery is down to 5 volts. Does anyone have any recommendations as to what I...

I have a factory fitted AGM battery on my T6.1 and I've noticed recently that the volts are dropping by up to 0.2V per day. My set up is a 75 amp AGM leisure battery with Redarc DC-DC (to bypass the smart alternator) and PU 170w solar panel, a feed for my Sergent with isolation switch, direct...

Hi, I've been having various problems with my starter battery over the past year and am not sure what to do next. The 2016 van was converted and a VSR was installed by the chap who did the conversion, which I've come to realise isn't suitable for a van with a Euro 6 engine. I replaced the...

Hi, I have a 2017 T6 with a factory fit leisure battery under the passenger seat and I recently wired up a combined USB, 12V socket and volt meter with a switch to the rear cabin area. I connected this directly to the leisure battery with an inline fuse (both positive and negative were direct...

Morning my new to me van 2018 t6 only had it a couple of days,this morning it wouldn’t start Engine turned over and over on the 4th attempt just before giving up it just started. Got to work started fine no lights on dash etc any advice welcome as going on holiday with it on Saturday...

Hi, sorry to bother you. Come across a massive issue on our first trip. So..... I have dc dc charger, all working well. Sargent system, but only plugged into leisure battery. Didn't run any cables to starter battery at all... Yesterday was fine. Plugged into hook up and turned charger on...

Hello, I have a 2012 T5.1, had a it for a couple of months now. The battery has drained a couple of times now, initially i thought it was the hard wired light the previous owner installed which stayed on every time the doors opened. I disconnected it and thought that was the issue fixed...

Morning all, The battery in my T6.1 is a EFB+ 420A 75A standard VW battery. As the van hasn't being used a lot, the battery was showing as under 12v. I used my Victron 7A charger on AGM settings all day yesterday to get it up to full charge. Afterwards it was reading 12.87V. This morning it...

Been looking into causes of a battery drain. Vw dealer say it’s down to the rear alarm sensor and won’t touch it as it’s been tinkered with or removed by the converters(who aren’t local) Carista shows up this sensor error. Anyway, here’s the last few days charts. 6th is with a fully charged...

[Guide] Battery Maintainer (for Starter battery) -- How I Done It -- Right so its that time of year again . . . . . . . . Winter & (Lockdown 2020) The van might be layed up not being used, which will lead to a flat battery in around 3 weeks. The cold weather doesn't help the battery's...

My friend has an 04 T5 she bought while renovating her house to move stuff about and still has it 5 years later. Apparently it keeps draining batteries, a local guy told her it’s the interior light causing the problem and “fixed it” but the fault has returned. Any ideas what this could be? I...

Well loss of plot anyway. Straight away I have to confess I did used to be an electrician... ok, an average electrician but when it comes to leisure battery upkeep on a T6 I've found it far easier so far to put my fingers in my ears and go la, la, la than try and understand what is going on...

Interesting one. I've had a few problems with my starter battery discharging (its a Varta, not a Moll so thats not the issue!). Basically my battery goes flat after around 5-7d inactivity. Thats pretty short imo. This was an issue before lockdown and is not just due to the extended hiatus. I've...

Hi all, I've been having trouble with my battery discharging if the vehicle is not being used. Takes about to weeks to go flat. I've taken it in as it's covered under warranty and they have come back and said that because it's a new type of van the alternator doesn't charge that battery anymore...

Hope everyone is keeping safe and well. Has anyone had a parasitic battery drain on their van? Just had a new battery on mine and it’s draining after standing for 3 days. Are there any known troublesome components to target before starting to pull individual fuses ? My original battery (Varta)...

Hi all, noticed that because my van, t6, 2017, is parked on the drive most of the time, especially the last month, for obvious reasons, after about a week the battery goes flat and won't start the engine! I have given it a good discharge and recharge with my ctec, this defo helped keep the...

Just had my claim for a new starter battery (AGM) turned down because the parasitic voltage was excessive and is caused by the installation of a leisure battery. This was before I told them that the fuse to the leisure battery was removed but they stuck to their story and wanted to charge £115...
