sure why but out of ll the Audi's we have done DPF removals
and remaps on it always seems to be the 170 BHP version - with
the seimens ECU.
failing to force a regeneration by the usual methods the customer
had hear good things about us (of course) from other Audi owners
to book it in for a removal and remap.
clear that the DPF problems were fairly terminal. We advised
over the phone the different ways in which they might be able
to clear up the filter, forced regeneration, clearing the codes
and going for a longer motorway drive,and checking the pressure
differential valve, but it would seem the end result was either
removal or replacement.
removal of course was something in the region of £1000
cheaper, but it makes no difference to us. Our labour rate would
be the same if we were to bolt a new one on so...
after the DPF (Particulate filter) is removed and replaced with
quality T304 stainless bypass pipe that we custom fabricate
in house on the car - the ECU does have to be updated to include
a DPF delete function. This will stop the error messages ever
re occurring as 1) the DPF will never fill up (doesn't have
one) and 2) it will never try to regenerate - to find out it
doesn't have one. Its a bit tricky with the Siemens ECU using
a Can BUS protocol but nothing we cant do.
do not remap the car after - the ECU will try to regenerate
the filter by pumping lots of fuel into the exhaust system to
get it hot enough to break down the soot deposits...and as there
is no filter...it will just smoke like hell and could over a
period of time damage your engine. Under no circumstances would
this ever be a good idea.
result, an error free ECU, no DPF problems and a hike to 210
bhp and 325 lbft of torque - an all together more driveable
and peasant place to be. Smoother and saving 10% on fuel over
a standard car.
