W221 DPF pressure sensor position on my car

[Malcolm Johnson]

Morning all,
Concluded from research on the net and the error codes I'm reading and increased frequency over the last 10 months my My DPF pressure sensor is on its way out.

i'm wondered if anybody knew the sensor position on my vehicle ?

Best regards

Malcolm

It behind the engine behind the silver heat plate if it’s a 221, back of the air box if it’s a 220?

If its the S350 bluetec listed on your avatar then you will also need to software update the engine ECU to match the new sensor.

Thanks for the Comments, did find the item behind the heat shield, easily accessible . Picked the part off the stealer this afternoon.
will change tomorrow morning and reset with my icarsoft v2. Curious why i need a software update?

Replaced the part Thursday afternoon, error messages gone and not returning after weekend away and a couple of 100 miles, everything tip top again.

Hi, this is going back a bit, I did not reset DPF pressure sensor after install. Error messages just went when new part fitted.
