Hi,

I normally lurk on the Superb I forum but have a problem with a friends 170 bhp TDI (it's a Touran by the way but suspect hardware is similar to Octavia, Golf etc), specifically it is throwing error codes (scanned with VAG-COM) which indicate the Exhaust DPF Pressure Sensor is duff.

001139 - Exhaust Pressure Sensor 1 (G450): Signal too High

001137 - Exhaust Pressure Sensor 1 (G450): Implausible Signal

I've run manual regen, cleared codes and the car is still displaying the DPF and exhaust (engine block) warning lights.

I'm going to change the offending item but am looking for help on locating it, is there anybody out there who can point me in the right direction.

Thanks in advance

Behind the head roughly in the centre. Torx to remove it as far as I remember. Watched 4 being fitted to my Touran!

My car has just been into the dealer for this fault.

Is your a PD or CR as they are in different locations.

On the CR engine, its on the braket at the left side of the engine cover. Its the bit that has 2 pipes running into it from underneath.

Hope this helps.
