Hi all, i'm quite new to this club and have noticed that their seems a large number of EA189 emission update/fix/cheat problems from a varied amount of Audi models, like yourselves i've also been tricked into this update back in February and so far have only suffered a slightly less refined running engine ,! No failures yet !! However I have run a standard VAG com diagnostic with no faults .I have called Audi uk. to discuss what they intend to do returning our A6 tdi 170 Le mans back to it's previous quiet and refined state and the Audi employee replied with "We can plug your vehicle in to check but! if not fault is found you will be charged £60!!! ,This is all we can offer" . I'm still chewing over this and have thougot about a basic economy remap which may cost £250-£400 but will kill many birds with one shot . Remove this dreaded software fowl up , improve linear power delivery, possibly better mpg, increase power as a by product and save based on feedback on this subject £1500 ish from EGR/ DMF replacement . Just some food for thought maybe. Let your insurance company know though if you have this remap done.
