Thanks to this lovely forum, I finally managed to fix my other half's 2014 fiat LCD. (https://www.fiatforum.com/500/480391...atibility.html)
Along the way however I did pick up an extra speedo (https://www.ebay.co.uk/itm/Fiat-500-...72.m2749.l2649) that is surplus to needs. Note has no part number and was a bit of a gamble. I can confirm that it is fully working, has about 60000 miles on it and has a pre 2014 LCD configuration (not the VCOG 1592-02 version LCD I needed).
Ideally collection from Leeds but might be willing to post if buyer doesnt mind waiting around a bit.
