Evening all quick hopefully simple question is this the dpf differential sensor on my 2011 fabia 1.6tdi?

Have seen other posts that's it's up by the washes neck, near the coolant bottle but confused as hell?

Think thats the one that on the exhaust? if you look under the car in the centre youll see the DPF and at the front theres a sensor.

Do you know what it's called though? Everywhere I look I can't find nothing to show this type of sensor that click on instead of.bolt.on?

It clips on not at the exhaust connector but behind that about a foot. 

 

Cant remember  the exact name of it 

This looks very similar to the EGR cooler solenoid valve. Although I cannot guarantee this to be the case. If you have a Haynes manual, take a gander at page 4E.3 and look at the photo 3.3b

 

Of course, I could be completely wrong!
