Audi A3 PDF warning light

[leftear67]

Can anyone help, i have an Audi A3 170 and the PDF warning light has come on.
It started first with the light coming on 2 days later the glowplug warning light and the engine management light came on and to top it all it went into limp mode. I was reliably informed that it was the exhaust pressure sensor and the fault code and the problem as remained. Today i have had the car to an independant Audi mechanic who has tried a new exhaust pressure sensor again and the fault codes are still there.
Acording to the auto logic software he uses the car last did a regen 9km ago , he can not do a forsed regen because the fault code can not be erased, the fault code throughout this has been 08194 particle trap bank 1 efficiency below threshold p2002 short with power . Acording to the snapon scanner the ash mass in the PDF is 43.5% .
Anybody any ideas on this please ?

am lookin at a photo i took of the solus screen of the fault and the code it reads 08194 particulate trap bank 1:efficency below threshold p2002 short with power.doesnt give any indication as to what

when you say exhaust temp sensors do you mean lambda sensors , had the vehicle in audi bolton came out exactly the same ??

they fitted the first new exhaust pressure sensor . when i got the car back off audi the glow plug warning light and managment light were still on but it was,nt in limp mode . they seemed to be happy at that point and let me part with my money {i wasnt but, i cant be arsed arguing with them just want it sorted now } not a good experience of a maine agent, is trap 1 the inlet side to the dpf or the exhaust side of it
