Help with W211 fault codes please

[SL300-24]

I could use some help please fellas………..

Just pulled these codes from my W211 320CDI V6 2007

P2A00 O2 Sensor circuit range/performance bank 1 sensor 1
P0670 O2 sensor circuit high voltage bank 1 sensor 1
P0670 glow plug control module circuit/open

Now the car turns over a lot before starting from cold so am I right to assume that a new glow plug module would sort this out, if so where is it located on the car.

The car runs fine but this is my first time using a code reader. Can anyone help with the first two codes? What do they mean any ideas?

Thanks for any help

This is I6 engine I assume, so may be different location...

What was the code reader?

Is the glow light on after start?

Edit: Here is V6 (part number 10)

Jus a quick update, changed the glow plug conntrol module and it is now starting as it should.
Can anyone help to identify the first 2 codes, is this a lambda sensor problem? or is there an O2 sensor located somewhere else on the car.
Just not sure where to look to sort the codes out.
I did erase the codes yesterday, went for a drive and they have returned any help would be appreciated.

The live data for the sensors need to be checked to confirm the fault. Fault codes are only half the info.

Saying that I suspect the upstream sensor is faulty. £205 each IIRC

Thanks Olly, my OBD11 scanner can check live data so may be okay, can you let me know the parameters for the sensors.
Also what do they actually do? I can see no problems when driving.
Thanks

The bearer of good news!

I'm sure I've seen this thread somewhere before

They do suffer with O2 sensors, the code usually comes up with a description that says upstream O2 sensor, but there is only 1 on this model so don't be fooled by the description.

The upsteam sensor described above I am thinking of changing. Can anyone explain exactly what it does?
