Greetings Again,

Can someone please let me know the location of the O2 sensor?

2009 MK2 Scout 2.0tdi BMM

I have spent hours on YouTube and no one has the same motor.

In pics is it the the one with the crinkly GREY coloured wire cover?

Also what is the easiest way to remove?

Thanks

It does look like an o2 sensor but by the look of the situation may be difficult to get a spanner onto it. If I remember correctly there are two one before the Cat No1 sensor and another after No2 sensor You might need a crows foot spanner on an extension bar. I got this sealey set to do ball joints on my sons fabia.

Remeber to disconnect wiring first to stop you twisting it as you remove it or when replace it

ok thanks Alasdair,

my o2 sensor is 0v 0data.

I don't know if it's the turbo vanes full of carbon or the o2 sensor causing problems, car drives well first drive in the morning once warmed up, then later drives it performs poorly.

I read somewhere that when the engine is cold the ecu uses stored/cold values and then later changes to values provided by sensors, not sure if this is true, if it is then that could account for the o2 sensor being the culprit. But there have been times when I massaged and lubed the wastegate shaft that it also drove well later in the day.... hmmmm

If by oiling wastegate it improves it might be an idea to replace it. Had the same on mine and oiling cured it. In your case it may be worn out or perhaps faulty/hole in diaphram? In my case it overboosted and caused limp mode. It was also fine when cold but seemed to happen when car was upto temp. As for the o2 sensor if its reading 0v then something is wrong. It could be wiring related or a bad sensor. Have you had car read for fault codes etc.

belated update: yes that is the Lambda Sensor. Need to remove the air pipes, and the throttle body (requires M10 spline/triple square socket) - No need to disconnect D type connector as enough cable length to just move TB out of the way. Then using a crows-foot type o2 socket, it came out easily.
