I need to replace the O2 sensor, Bank 1 Sensor 1. I believe this is the sensor just before the CAT (after the manifold).

I have removed the engine undertay to take a look, I can see it but how the hell do you get to it to replace?

I have a 3rd party sensor and a set of various 22mm sockets for sensors, but is it removed from underneath? Its so hidden in the bulk head area!

I am unable to find any YouTube video guides for an FL2 2.2 Deisel on how to remove/replace.

Thanks in advance,
Steve

Just to add the issue is poor cold starting and zero BHP below 2000k revs. All 4 Glow Plugs were replaced (old ones worked when tested but were a little slow to heat up (directly on a battery))

After 2000k revs everything fine once the turbo kicks in.

The only code on the scanner is P0030-13 Heated Oxegen sensor Bank 1 Sensor 1

When trying to start and with a lumpy tick over the car produces white smoke and stinks, assuming this is unburnt diesel.

If you have long arms, then it's possible to do from below. From above is more tricky, as it's basically impossible to get at unless you remove the EGR assembly.

So from below it is then, thought it would be. WD40 and pray the exhaust does not get damaged.

Assume from the photo it is plugged in on the top?
Guess I can drop a wire from the top to tape the sensor cable to it? Or to use a wire grabber after to get it?

Yes. The plug is semi-hidden behind the harness at the back of the engine.
You'll need to remove the air intake pipe to see it.
I've ringed the bracket that holds the plug.
