Hi,

Hope someone can help?

I have a 2004 VW Caravelle 7H with faulty sliding power sode doors.
Sometimes they work ok, then they will not close fully and latch. Or sometimes they will bounce back. Very Random.
One question i have is on the measuring blocks group 05, the third box along is labeled as voltage. Do we know what voltage? is it battery, as all i get is approx 9 volts. This would explain why i get a fault code of under voltage at both door control units?
I've attached a scan showing the faults it came in with, then cleared and the faults which re-apperared.
Think this has been elsewhere before it's landed with me to fix!
I've also emailed in a channel map to support@

Thanks, Martin.

Hi Martin,

Thanks for the maps. That group is terminal 30 (battery voltage) according to our German label file for address 78:

Shop #: WSC 00000 000 00000

002 - Lower Limit Exceeded - Intermittent​

Your MVB observation is likely directly related to that DTC. I'll send you the German files we have in reply to that email so you have some labeling.

Next, ruling out low voltage is the best way to gain any traction on this diagnosis but I would also look at the power supply, CAN comfort wiring and similar to the remaining Comfort Databus modules based on the number of DTCs that appear to be specific to that bus. For instance 00565 - Rear A/C Control Head (Climatronic) (E265) - No Signal/Communication and 00478 - Control Module; Display & Input; Comfort CAN; Rear (J524) - No Communications returned right away so those may be worth locating and possibly unplugging for diagnosis reasons if the powers and grounds to them are OK at face value.

Did you get a new or verify the battery and verify grounds to the chassis + alternator or charging system as a whole and because it is riddled with DF stuff?

Did you check the door wiring harness for FOD chafe?

Hi Dana/Jack,

Thank you for your help with this one. I have got to the bottom of it now and feel a little daft. Time to eat humble pie as we say in the uk. But i feel a little better about it as this van had been elswhere for this fault before i got my hands on it!

So, after Dana confirmed that the measuring block should be Battery voltage i when back to the job and checked wiring diagrams for the source of the power for the door control units. This showed a connection of sort under the drivers seat (right). Now i have repaired lots of bad joints due to water corrosion under the carpets on T5's over the years which affected the central locking, so i thought this must be it. But on removing the drivers seat i found a second factory fitted Battery . Now this is a new one to me as i've never come across them on all the other T5's i've done (every days a school day!). Don't know if all Caravelle's have them or this is an option the owner opted for when purchasing this van new. No prizes for guessing that is was flat. 9 volts to be exact. It would appear this van has been parked up for a few months, and even though the owner has had a battery charger connected under the bonnet (like me in the workshop), it doesn't charge the 2nd battery. I haven't worked out all of systems yet it supplies power to but it looks like, power sliding doors, Cool box Aux Heater. The battery will only charge when engine running. It looks like it is not voltage controlled charging. (so 2 chargers need to connected when using VCDS)
I charged it up and check for discharge (9mA) and all apears good. Battery is also holding charge. Now we have good voltage all the door issue's have gone.
As for the other fault which where still there,
Control head roof - This had had water in it. I'm guessing the sunroof has been opened when wet and water has run back into it. Needs new one.
Heater - air quality sensor. Sensor faulty. Needs new one.

Many Thanks for your help and data. :thumbs:

Regards, Martin.
