It's fairly easy to do, i found it a lot easier using a lambda socket > Draper Expert 22Mm 3/8" Square Drive Lambda Sensor Socket: Amazon.co.uk: DIY & Tools

thanks, do i need to remove any engine parts to get to it?

I had to remove the strut brace but i don't think the APY's had one. You could remove the chargepipe to make things easier but it can be done with it staying on

I removed the inter-cooler inlet hose that runs along the top of the engine and this made it easy to access the lambda sensor. As sandip points out - proper tools always make the job easier, especially when access is limited as you will find out. It's a 30 minute job with a cold engine and proper tools. I spent a good hour on this as I neither had a proper tool to reach the lambda or the time to wait for engine to cool down
