Despite the mass of hot glue, I assure you that I am not the maker of this device. Does this mean the values are different on a BMW or are they selling this as a device to turn of the front airbag for child seats?

Ian, higher up the page you wrote "the correct values for the pressure mat are well documented". Doesn't this mean you can get those values without having to measure the resistance at the contacts?

I dont know... They are marketing it as a solution to help you fix the airbag light, there is no mention of safety or whether the airbags will still function....

Yup, and thats come back to haunt me - I know I've read the values somewhere because we used them to manually check a load of seats once that were already out of cars, but can I find that information now...

I might have to downgrade my statement to 'documented', not 'well documented'

I discovered the cheapest solution to my airbag warning light problem was to buy a whole new interior and fit it. Problem solved. Also gone form alcantara to full leather for less than the price of getting the job done at Audi.

I wonder if you could use a variable resistor in place of a fixed resistor? That way you can use vagcom to test the dummy pad, turning up the resistance until it reads "occupied" - then measure the resistance across the resistor to give you your fixed resistor value or thereabouts?

Or is that more long winded than the aforementioned...

Not a bad idea at all that, using that I could find the upper and lower maximum values, so that we could pitch it right in the middle...

Otherwise, sods law would prevail and we'd 'test' and occupancy sensor for resistance that was on its way out, and end up on the fine line between working and failing..

hmm.

Would it be feasible to trace the wires to an accessible point in the car, then solder some insulated wires in serial andmake them long enough to do the measurements?
Ian, you could be on to a sleeker Audi variant on Ebay for the bargain price of 30 quid a pop!

Sorry to be so dopey - if the airbag sensor light is on will all the bags deploy or just the drivers? I also care about my passenger. I can turn it off with the gadget that came with the car, but it always returns!

lads this has been done, I used a 1Kohm pot and connected to vagcom, I can measure the resistance that shows seat occupied , if anyone needs to know, let me know.

here is a new recaro heated seat element with airbag sensor mat and foam padding assembly,it also contains the heating thermostat for all the 5 heating elements in the seat, normally £300 only £100. I know because my heated drivers seat went cold this winter. disassembly is not easy. from germany ebay
