[GrahamMuggy]

Hiya. My 2009 4.2 q7 requires a replacement gearbox, I can’t find the right one anywhere, don’t no what to do , I can find plenty with the same part number but the end letter is different, with they fit and work. Thanks.

I think if most letters are identical it will fit but will most certainly need coding to your car whatever route you chooses.
