Got a wee misfire when cold and got fault code P2234 O2 sensor signal circuit shortened to heater circuit bank 2 sensor 1
Got told I need part no 1K0 998 262 AA. Anyone know best place to purchase this without going to main dealer

Looks like that part number equates to Bosch no. 0258007363.
There's quite a few listed on ebay, eg. https://www.ebay.co.uk/itm/Bosch-Lambda ... Sww~xZ2ShK

Hi was that a genuine one mate, is it a nightmare to fit

No it's easy enough drop the rear gear box mount to give you more room to get the plugs out. It was a bosch 1 same part numbers
