Thank you for posting this. Would it be the same for a T6.1 also?
T6/T6.1 operate front wipers with ignition off

T6.1 is based on MQB and its BCM adjustment works via adaptations.
But since this setting is possible on old PQ25 platform and wiper motor is also fed directly from the BCM, I am expecting corresponding channel to exist for MQB.
If I find some spare time I will do some digging on T6.1 too.

I tried this tweak on Transporter T5.1 2015
Code:
SW: 7H0 937 087 P
HW: 7H0 937 087
BCM T5GP H+4 H34 0424Genuine VCDS claimed that new coding got accepted but in fact it wasn't memorised by the BCM. I will try VCP and ODIS but it seems that this mod is not working for the previous generation.
Checked 2024 Cafter(obviously MQB) and its windscreen wipers also stop in random position after switching ignition OFF.
Transporter T5.1, T6, T6.1 and Crafter(maybe more) are factory configured like that, but why? Commercial? But my Caravelle/Multivan is not.
Quo vadis Volkswagen?

I can confirm that my T6.1 wipers stop in random position when ignition is switched off. It annoys the hell out of me.
Likewise - T6.1 Caravelle/Multivan - I particularly notice the rear having spent 15 years making sure the XC70 rear wiper parks properly when leaving the vehicle
It turns out to be a very simple tweak on a T6.1
Basically open your bonnet/hood.
Connect to 09, use SECURITY ACCESS 31347, select ADAPTATION and open channel:
That's it, job done.

Thanks Robert.
Made a little video of the process:
Confirmed for Crafter.
The same thing, open your bonnet/hood.

I must mention @dnoermann and his significant contribution in discovering this little feature.
Thank you @Robert and @dnoermann for this lovely tweak! It works beautifully and the wipers not returning to rest position when switching ignition off has been a minor annoyance for years.
I have checked Caddy SA (2015-2020) -> PQ35
& Caddy SB (2020-) -> MQB.
Unfortunately both get their windscreen wipers stopped in random positions after switching ignition OFF.
I always wondered how the BCM knows when the windscreen wipers return to the park (down) position. I used to think it was just a simple limit switch, but curiosity got the better of me, so I stripped it down — and it turns out there’s actually an extra brush on the commutator, set at a specific angle compared to the other two.
Ah, VW isn’t always perfect, but I still love these clever bits of engineering and the thought that goes into the design.
I would have thought that the second brush was for the second speed, all windscreen wipers I've taken apart had switch contacts built in to the gear box that closed as soon as the wipers moved off park, those contacts provided power to the motor even if the stalk switch was subsequently turned off that kept the motor running until they got back to the park position and the switch opened again cutting the power at just the right time to park them again.
can someone with a T6 (not 6.1) confirm they've done this, i went into VCDS yesterday and couldn't find the long coding for it? anyone got a screenshot of the bit/byte screen so i can compare to what i have.
thanks
thanks
This bit is not documented, so you have to do manual adjustment as per below.
Just switch to Lcode2 and you will be able to tick required bit.
Alternatively post your AUTOSCAN.

that will be why i couldnt see it, i should never assume everything we talk about is documented in vcds lol
