Hello all new member posting with a question for people with more knowledge than me about ducatos.
I Note on the 130 multijets that there are two flap valves on the chassis and crossmember immediately below where the back of the cab is.
these valves are a plastic plug a bit bigger than a pack of cards and at about 20 mph the rubber flaps open up and allow all the air to be sucked out of the cab, not very good in cold wet England.
My local Fiat parts knew nothing about these until I gave them the part number, and it is possible to exchange these worth a solid plug which doesn't pull the air out of the cab.
My question is does any one know what exactly what these valves are designed to do, and will it cause any problems changing them for the solid type.
Thanks for any advice.

Maybe they are there for chassis cabs where there are no tail light vents at the back of the van to let stale air and moisture out. If yours is a van, then it should be ok to block the plugs up. If you start to get condensation in the winter, opening the front windows half an inch will let the moisture out.
 
yes it was delivered as a chassis cab now its a motorhome guess I will have to be aware of possible condensation problems especially a motor home.
Thanks for your input
 
Hi. Lots of estate cars have this type of vent thing in the tailgate; I think it’s something to do with the air pressure when you close the door, nowhere to displace the air.

I blocked mine off once and the doors became very hard to close but O.K if you left the window open a bit, shouldn’t be an issue with a motor home lots of space to displace the air.
