[Is the Fabia MK2 OBD2 socket a standard size?]

I can only assume my Friends scanner has a slightly oversized connector that has not been made to the standard size

Thanks, it must be the plastic housing on the scanner plug that is just too large for the opening - I didn't want to start filing the sides of the scanner plug as it was not mine.  

Can anyone recommend a fairly decent  and "reasonably" priced scanner I can buy that would be compatible with the Fabia?  - Average prices at the cheaper end seem to be £20 -£40 
Would prefer the handheld type as opposed to a Bluetooth type that connects to a Smart phone.

I tried borrowing a friends OBD2 scanner and found it would not easily fit into the Fabia's (VRS - 2013) OBD2 plug socket located next to the fuses.   Looking at the connections the Fabia has a rectangular outlet surrounding the internal plug whereas the  OBD2 scanner is of a trapezoid shape (this seems to be common)   and is slightly larger than the Fabia rectangular opening!  So is the Fabia MK2 OBD2 socket a standard size or does it require a non-standard sized scanner plug?
