Cranking for 5 seconds then fires up

[Dellmassive]

Started ok....

Though I thought just a tiny % laboured in the crank?

How old is the starter battery?

AGM battery life is normally 5years. Your van is 2017. So original battery?

Post a few pics of the battery.

looks like the original 70A MOL battery to me,


might be worth getting it tested.

get your own tester - Amazon.co.uk : 12v battery tester


or take it to Halfords et for a test.



good to see the negs are on a chassis point and not on the battery Neg post

Will do! Are the testers you can buy off Amazon any good or better off taking it to a garage? https://amzn.eu/d/gK8WZDr

Protyre near you do a free battery check. Just be prepared for them to try and sell you one but there's no obligation.

 

[james_bt6]

Thanks all, will try and get booked in for a battery test tomorrow and report back

Mine does the same thing even after a new battery. There's no rhyme or rhythm to when it wants to do it. Be fine for 50 starts then just turns over for a few seconds. Thinking it could be a sticking egr or fuel return valve that's on its way out.

Had a similar issue and after Vw assist had a look… a new control module on glow plug no.3 was replaced under warranty… no issues since

 

[B.different]

Daft question is there one for each plug or is there just a master one

Sorry for the delay - had the battery checked by Halfords and the reading was 161% turns out I have a super battery!! I’m assuming there must be something going on with the wiring of the professional conversion - maybe the leisure battery is juicing the starter battery? I don’t know, I’m not clever enough for that.

However with that reading are we happy the starter battery is good? That then leads me to the glow plugs - question, is it possible to get them checked before they are replaced? I mean if they are all good I don’t want to fork out money to get them replaced. I’ve found a reputable garage who specialises in glow plugs, but still worried about any of them snapping.

Honestly I've no idea what "161%" means here... it might just mean whoever tested it Halfords doesn't have a clue.

With electrical weirdness once you've eliminated the obvious it's always a good idea to consider starting from a known good battery before spending serious money or taking things to bits. Counting against yours is that it's a MOLL (which have a known bad history) and potentially 7 years old.

I did question the reading and she just shrugged… I’m actually thinking of buying my own battery tester off Amazon before I start shelling out money on glow plugs etc. Does anyone recommend a good battery tester that is user friendly?

I've got this one. . . simple to use, and easy to read.

If you spend £50 on a battery tester keep in mind the new battery will be about £150

Honestly I'd just get a fresh battery and eliminate it as a possibility especially if yours is long in the tooth. It's not much more than filling the tank up in the grand scheme of things.

You make a really good point to be fair - do you know if there’s anywhere online that will give you the correct battery if you put in the van details? Sorry, I’m terrible with stuff like this, can drive the van, sleep in the van and that’s about it haha

Most of the usual sites you can put your reg in to get suggestions - but always double check against your actual battery measurements and terminal layouts.

I tend to use Tanya but there are others.

Read somewhere you need to code in a new battery when fitted via a Carista dongle - is there any truth in that do you know? TIA

If your van is start stop then strictly speaking yes the BCM needs to be updated at least to reset the health data and, if you change size, the capacity.

If you swap like for like then the usual trick is just to change one number in the battery serial number so it knows it's new.

However it should adapt over 10-15 charge cycles if you don't. It's not going to do anything critical, it just might not charge optimally and enable start stop until it's happy.

Upgrading Starter Battery - how to guide

My van (April 2017 T28) is fitted with a Moll battery. I am experiencing some issues with it not starting after a few days sitting on the drive. Now this could be due to the tracker I have fitted draining it but I doubt it, I'll do some drain current tests before taking the plunge. If I were to...
