Newbie here, so apologies for any idiocy. Drivers side heater not working. Still blows air fine but only cold! All others working fine, passenger side and the all the back (have a T6 shuttle). Can’t work out why the blower works but no heat and only a problem on the drivers side. Took it to VW van centre and they had it for hours and said they don’t know either but want to book it in for FURTHER diagnostics at a cost of £180! Help!
Heater issue. 2018 T6 Shuttle

Do you have the climate AC panel?
Got a pic?
It will most likely be the blend doors stuck or faulty...
You can try a full power reset...
Also try setting the blowers on full power and cycle through all the position settings on full hot then full cold...... do this cycle about 5 times to see it it frees up the flap motors..
It's also good practice for everyone once a month to keep the blend doors operating proper.....especially if like me you normally just keep the dials in one spot....
Learnt this from experience on the T5.1.
You can play with the blend doors in the HVAC mod via VCDS.... and do a factory default position setting.

hi. I've the same problem as the author. passenger and rear is fine but drivers is cold. its showing no faults, both probes in side vents are working. my friend is baffled by this, says it could be little radiator in matrix. he's come across this problem with vw passat but not the T6. it's 2018 with the climate controls. thanks and much appreciated for any help.
this is the controls

hi peeps. heater went doolally on Satdi.
passenger and rear is fine, nice n warm, but drivers is cold. its showing no faults, both probes in side vents are working. my friend is baffled by this, says it could be little radiator in matrix, half full of sludge. he's come across this problem with vw passat but not the T6. it's 2018 with the climate controls. thanks and much appreciated for any help.
sorry forgot to say its the shuttle. cheers

It won't be sludge in the heater matrix. The electronic controls behind the dash are complicated and there are a number of threads on here about various issues.
If you aren't prepared to dismantle your dashboard to get to the controls, then it needs to go to a garage or dealer I am afraid.

cheers Pete. I'm prepared to have a go at anything, have you come across this issue before. everything is toasty apart from drivers side screen, feet n front facial vents. are you thinking it's an electrical issue. I've looked at other threads n none with partial heating. thanks again
my pal works at hayselden vw in Barnsley. bn on his laptop, everything is working OK, temp sensors and flaps. no faults showing, that's why he mentioned the sludge in little radiator stopping heat coming to drivers side, common fault on passat. waiting on reply from his colleague at van centre. if you guys are in the know n come across this before. we're both baffled.
How about back flushing the heater matrix if you think there is a sludge restriction.
I have no idea where the hoses route but I suspect the engine compartment is the best access. Back flush with a domestic water hose but watch the pressure, mains pressure can be high in some areas.
Need to physically check the control flaps as the stepper motors may be ok but not moving the flaps due to linkage issues, then you say the sensors are ok again can’t rely on fault codes you need to look at actual temperature readings at set or actual temp because they could be misreading and shutting off the heat I’ve had in vent temp sensors on Octavias miss read temp and shut of the heat
hello again. I've taken bottom part of dash off and found the fault, woohoo. it's this black n white link. as picture. I can move it by hand n back to being toasty again. doesn't move with controls, so leaving it with heat due to miserable weather. im thinking motor or something. thanks again for the tips. russ
