Hi All,

Started up this morning and the ESP light along with the above light showing skid marks both lit up on dashboard, anyway long story short the car is in limp mode, no power and will only rev to about 2800rpm, I turned engine off/on again while sat at red lights in traffic a couple times but made no difference.

Anyway ran a diagnostic just now on an OBDII reader I have and its showing P0470 which is 'Exhaust Pressure Sensor' which is related to DPF function but over a year ago I had the DPF removed and it mapped out the ECU and car has been flawless since now this has started. :evil:

Does anyone have an ideas about this and more importantly where is this sensor located as looking around under the bonnet and also removed engine cover I cant see it anywhere (googled what is looked like) ??

Oh is a 2008 2.0 DCi Tekna, thanks in advance for any help :)

It seems there are two exhaust pressure sensors shown in the service manual - an exhaust gas pressure sensor
and a differential exhaust pressure sensor.

The first one is shown at the back of the engine, but the diagram is a bit vague.

The second one is shown under the front end of the car.
