Habitation Door lock broken

My wife and I own a 2010 Nuevo EK two berth motorhome from new. Recently, we have experience difficulty in securing the habitation door because the bottom of the two bolts is loose and does not engage properly. Any advice on what should be done would be gratefully received. I will send photographs in a separate posting since I have tried this afternoon to send text and photographs to no avail.
If no photographs follow then I apologise still ask for any advice from members. Thank you in advance

Do you mean problems with the snapover catches or the u bolts that are fitted to the door frame?  My 2012 started to have problems where the bottom snapover did not engage properly,saving the door only half caught at the bottom. I thought one of the lock springs had failed but a long trial and error process of adjustment of the bottom u fastener on the frame made the door lock better than it ever had since new.

This is so frustrating because I have taken very clear photographs of the problem but am unable to upload them to the website.

The problem is with the locking mechanism on the very edge of the door, not the frame of the the door which is part of the motorhome itself.

The "bolt" in the locking mechanism should have great resistance, but I am able to move the lower locking mechanism with my finger.

Sorry, but that is the best description I can give.

Send your photos to me by email (I've sent my email address by PM to you) and I'll  put them on here for you.

You should be able to rotate (with a finger but against some resistance) the claw in two clicks, first to the half latched positions and then to a fully closed position. In both of these it should not rotate back again without pulling the opening handle but pulling the handle allows the claw to return to the fully open position. The function of that claw is to wrap itself fully round the D shaped hasp and to hold the door securely closed, even against a crash situation. If the D hasp is not properly adjusted it can either allow the door to rattle (too loose) or prevent the claw from fully rotating thus causing the door to bounce back to the half closed position. Getting the balance right in that adjustment of the D is quite difficult and also critical. In my own case the lower D was too tight so that it was preventing that claw from getting to the second click. It took a good half hour or so to get the adjustment right but, when it was right, the claw pulled the door tight closed. In some instances one or both of the springs on the claw have broken and then no amount of adjustment will help the claw to grip properly. But the springs can be replaced.
I hope that helps.

Jaime has still not been back on forum  I've deleted my PM to him.

I've received photos from James so here they are if anyone can help...

And more...

That looks very much like a Dometic seitz handle,  do a search on google for problems with that handle

Probably the hooked rod connection (no.2 in this picture) disconnected from the latch?

Just to clarify, I'm not a moderator.

You can ignore my comments. My Hartal locking system is totally different from yours.
