Dear all,

I would like to ask all Grand California (600 or 680) in Ireland if they could get back to me with their experience of the Truma heating switching off.

As far as I know this is a well known issue with many of the Grand Californias, doesn't matter if it is gas or diesel heater, if it is on EHU or on battery, if it is heating or warm water (please see Caliboard.de).

During the last cold spell I kept the heating on 10 degrees to insure that inside of the camper it is not to damp and that the frost control would not drain the water (I use the camper at least every 2nd day).

Of course the heating switched off regardless of the circumstances. This was not a big issue, because we were at home, but it is not acceptable if this happens when one is out and about.

I contacted my VW dealer at the end of November, but haven't heard back from them yet. Today I did send a reminder email.

I would like that the my VW dealer, with the ok of VW Ireland, will install the Truma iNet Box. When the Truma Control Unit is disconnected from the VW Camper Unit the issue is gone and with the Truma app it is possible to change the temperature comfortably.

If my VW dealer is not able / willing to help me (which to some degree I can understand, because without the permission of VW Ireland they won't change anything at the camper) I plan the following:
  1. Open an official complaint about the issue with Volkswagen Ireland
  2. Open an official complaint about the issue with Volkswagen Nutzfahrzeuge, Hannover
  3. Contact SIMI Ireland to help to negotiate between Volkswagen and me
I know there are many threads about this, but for the argument sake (with VW Volkswagen) I think it has more impact if there is information about Irish Grand Californias.

The more users of the Grand California have the same issue, the more it is likely that Volkswagen Ireland might want to do something for us.

Regards,
Eberhard

I have this happen to me on the drive but I am not in ireland? Does it happen regularly? What if its the middle of the bight, it dumps water and freezes the occupants! Almost grounds for not fit for purpose!
I will disconnect the unit from the truma control.

Hello @Chainline,

I'm also frustrated about this issue and I agree it is not a small issue.

VW Ireland won't entertain any reports or complains. I won't blame the VW dealer, because they can only undertake work which is ok by VW Ireland.

Fakt is that an unknown amount of Grand California's suffer from the issue that the Truma heating unperioticaly switch off. Unfortunately if this happens there are no entries in any logs of the camper which means from the VW dealer point of view, everything is ok.

Depending on the weather of course during autumn, winter and spring all the freshwater in the Grand California can be dumped, leaves the occupants without water the next day, not even for a cup of tea!

What the situation with the irish Grand Californias is, I don't know, because nobody came back to me about this issue. Maybe I am the only one. Without more detailed in formation I can't put more pressure on VW Ireland to pay at least for the workaround.

The only known workaround for this problem is to disconnect the VW Camper Unit from the Truma Control Unit. But this means that all further heating related changes have to be done on the Truma Control Unit under the back seat - not ideal on a long term.

I caved in and ordered the Truma iNet Box. But there might be another issue on the horizon. I believe that the Truma iNet Box comes end of live. Many dealers in Europe won't have the Truma iNet Box on stock and lead time could be into the months. The replacement, Truma iNet X Panel might be even better, but it seems to me it is far more difficult to install.

At the moment I wait for some cables to get the Truma iNet Box installed. If everything arraived that I need I will do the installation myself and will post what I have done (with pictures) here in the forum.

Every so slightly frustrated Grand California,
Eberhard
