Hi

My front passenger door hasn't opened automatically for ages I am trying to save maybe $600 by buying a part second hand as I can't justify the full Ford price.

The part from Ford that I've been quoted has a part number 8M2AR21813CB (this is also visible on the photo of the part) and it goes for $683 but I've found a second hand one on eBay for only $66 but its part number is 8M2AR21813CA. Both are listed as for the left front door lock. The difference is the final letter, "B" at Ford vs "A" on eBay (smash repair dealer located in AU).

I've got a 2011 MC Titanium TDCI but the eBay part says it came from a 2010 2.0 petrol 107kW.

Any way of finding out if the parts are identical and I can safely use it?

Thanks in advance
