Hi there,
I have a 2014 plate Seat Alhambra LUX (Same as Volkswagen Sharan SEL).
It comes with almost every extra
I have a Micro-CAN usb Dongle for the Scan

basically the element heater works and heat comes from the front
ventilators, however, the rear ventilators are supposed to blow heat
after the main water heater matrix system heats up and supplys
warm air to both the front and rear ventilators.
hoping I got the above statement correct, seems to me the heater
element is not turning off or some sort of valve is not switching to let the
heat from the heater matrix supply heat to the whole car.

could you let me know who to email so I can let them know this problem
please ? my car is also showing no errors on a full scan relating the
heater problem....

Also I do not know what the headlight range fault is....

Here is a Scan I have just done below..

The "Left/Right Driving Switch-Over Active" fault is an advisory. There's an Adaptation channel in that module:

IDE03787-IDE03632 -- Activate left/right hand drive switch-over (not active / active)

This is intended to be activated when one is driving in countries where the configuration of the vehicle is incorrect for the side that traffic uses there.

Have you tried going to Security Access and waiting there a bit to see if VCDS makes a suggestion? I'm confident it will.

You have a very well known common fault. There is a valve which is underneath the car that requires a software update and replacement depending on which one you have. I think the part number you need is 7n0819810e. It has to be 'e' or later and then it requires a software update.

Hi everyone,

I found the diverter valve. It is above the drivers driveshaft. It is a struggle to take the whole diverter valve off, as the nut is only accessible form the top of the cars engine bay, and there are aluminium air con pipes in the way, so you need an angled socket or something like that ( i couldn't open it with angled socket - too tricky ) , plus more time consuming as you will need to disconnect the incoming and outgoing hoses, and wiring. plus possibly re-programming.

Luckily after seeing the most recent information above, i took the side panel off which was three screws. You need to take the under engine protection panel and you can access the side panel of the diverter valve.

The shaft that breaks....one side breaks in a cog. That side can be taken out using a stanley blade to pry it out against the cog. This cog sits on a pivot on the side panel that you have just taken off.

The other side can be pried put with a thin flat screwdriver. it is on the main unit that is still attached to the car. I pried out the arm......the arm will be facing 9 o'clock position or maybe 6 o'clock or different. (i just remembered this as not sure if important, and put the replacement part with the arm facing the same way)

The aluminium part above came in 5 working days. Worked out about £42.00 delivered which is expensive, but saves waiting for another plastic one to break in the next 4 years (not a good idea, and not sue if its available separately from main dealer)

i would post pictures but they need to be uploaded to a URL, and i don't really know how to.

Thanks for the information above. I hope this can help solve future problems, as these are relativity new cars. Took 3 months to solve, but well worth it, and it is getting cold now here in the UK, so will hopefully be useful, and it works now!

Great thread! and great forum.

I have the same problem with my 2012 Sharan rear heater valve, and have swapped the little cog inside once already.

@myounus Do you have any info on what the software update does? I can't decide if i should just get the aluminium cog, or if the right thing to do is to get a version 'e' valve and the software update.

As far as i can see the cog doesn't break because of a stuck valve. ( i can easily turn the valve by hand using a small screw driver).

And lastly, where can i do an output test for this valve in VCDS? I assume it would be in 08 -Auto HVAC module but there is nothing there for any heater valve or N317 valve??

any help would be appreciated.

Hi Phil

I've not read a TSB but I presume the software update fixes a bug. Parts are routinely superseded due to technical improvements / recalls etc. Companies are always trying to cut costs and use shitty bits only to end up recalling cars, but if they get away with it then they do.

Its probably the cold weather causing weakness in the plastic, or causing a slight jam, as it is close to the inner arch/subframe

Looks like I have a failed N317 valve, is there any output test in VCDS to test a repaired valve?

Great thread. I am on my second diverter valve in my 2012 Sharan. It is stuck in cloded position. No warm air in the rear. My car has a Webasto parking heater and I am thinking of just setting the valve in open position. I realize it will take longer to get the engine to working temperature, but it is tempting.

Question: Would such a sollution lead to the rear heat exchanger deliver hot air constantly? Also during summer when AC is what you need?

What’s the point, just replace it
