EML and fault codes after repair

[MurrayT6]

Morning,

My 2016 T6 Euro 5 has been in the bodyshop for two months due to repair to rear door.

During a phonecall before I went to collect I was told my EML was on and asked if I knew about it - it certainly wasn't on when they got the van.

When collected the coil light was also flashing (this was never mentioned). Would go above 2000rpm on drive home (limp mode?). Stop start mode also not activating.

Now I know they have disconnected the battery and my van does have a leisure battery also.

The coachworks are denying it's anything to do with the repairs. I'm convinced it's because they've disconnected battery and leisure battery. They have said that they took the van to a VW specialist who said its auxiliary collant pump. Would this be the cause of both faults?

Two fault codes showing

U100800 - Data bus on board diagnostic
P261A00 - Collant pump B control circuit open

Any thoughts/experience welcomed . . .

The code tells that the actual fault code is shown in controller J533. So what's the fault shown in 19-Gateway (J533)?

Not sure but my mechanic is stumped. Seems to now think it's a broken wire somewhere.

Battery getting 12v but then when putting load on it doesn't carry - break in the circuit somewhere?

Leisure battery seems OK and holding charge.

Could it be due to repair on rear and wiring issue on taillights. .. . .not sure.

So anyway I think I'm going to take furniture out and take it to the chap that rigged out the electrics and leisure battery so see if he can chase the fault.

Unless anyone has other ideas

Surely it’s nothing to do with the leisure circuit. Not sure you’ll achieve anything by ripping out the interior.
I’d guess you need to work on the fault codes and check the wiring to the aux pump.

Yes doesn't appear so. Picked up the van meantime. Victron connect shows all OK with leisure battery.

It's PlyGuys furniture so quick bolt out if needed.

Thanks will get wiring to aux pump checked
