I use Carista app and dongle to read the codes and had P0299 and P1103 showing.

Did lots of googling and was about to order a new MAF SENSOR first then maybe a turbo, then I can across your post. On a whim I order the part you mentioned (https://www.ebay.co.uk/itm/Ford-Focu...72.m2749.l2649)

Fitted it last night and it seemed to have worked! Cleared the codes and re scanned and all is fine, car drives normal again. Whilst I had the the under tray off I gave the car an oil change too.

So thank you very much!
