All,
I appreciate that this thread goes back some what and some of you may have already forked out to repair your vehicles but hopefully this will help others.
I took my A4 into the Audi store earlier this week after waiting 3 weeks for an appointment.
My malfunction light has been on for some time and there has been an intermittent smell of burning coming from the exhaust on shorter haul journeys along with noticable increase in heat when at the rear of the car. The error code was showing a lambda probe issue.
I had to pick my car up again from Audi the same day and have just dropped it off this morning.
By some very convenient coincidence I came home yesterday to a Service Action letter from Audi relating to EA 189 Diesel Engines - It's a goodwill policy following the Nox "fix" for all exhaust components. Which includes EGR, Injection System, Emissions After Treatment, Lambd probe, temperature sensor, EGR changeover valve, exhaust gas re circulation valve, exhaust re circulation pressure differential sensor, injector, high pressure pump, fuel rail, pressure control value, pressure sensor and high pressure pipelines.
Essentially, Audi appear to start admitting that this "fix" causes significant issues for a portion of the cars which it has been applied to.
My car is back in today and I'm just waiting to see what they come back with!!
If any of you want a copy of the letter - please feel free to contact me.
Cheers,
Scott
