Help! Audi A4 2.0 tdi DPF. PO472. g450 Exhaust pressure sensor 1
 

Hi All

Would appreciate any comments or experience you've had regarding this.

I have a 2009 Audi A4 2.0 tdi 170 DPF

The Emissions Light has come on, I have got it put on the computer and come up with the following fault:

PO472. g450 Exhaust pressure sensor 1 - signal too low - defective

Has this happened to anyone? any ideas of what the fix could be?

Many Thanks
Az
