Hi, The instrument cluster on my A3 1.9 TDI Sport has gone haywire and needs replacing. Part number on the back says 8P0 920 980P, but I can't find a second hand one with the 'P' suffix. Worthing main dealer want £700+ to fit their recommended part. However, my local garage have all the necessary kit to recode a replacement for little money if I can find one second hand. I can see numerous ones on eBay etc for sale, except the last digit is different, e.g. a 'Q' instead of a 'P'. So how important is it for this last letter to be the same, I.e. will it completely not work, or will I just lose some non-essential functionality. For those interested, I've posted a short video on YouTube called 'Audi A3 dashboard fault 12345' (posted 12 November 2012 by jonno1234567) - Link below - which I uploaded for BBA-REMAN. Alas, their attempted repair didn't work. Audi A3 dashboard fault 12345 - YouTube Any advice gratefully received. Thanks for looking. - Jon P.s. The fault originated after a new alternator was fitted. Cedar Garage, Worthing, are convinced it is a dodgy instrument cluster.
