Please check out pictures on the left, the car in question together with the official emission test results.
Please find below the original description added from the owner of that car:
“Sooty particle emissions decreased by 88% at Audi80 year 1992!
As an employee of the municipality Neulengbach, I was at the lecture of Mr. Ing Renner in the hall of Lengenbach in 2013 and bought in civil action one of these “miracle sticks”.
My old Audi 80 1992 had significant problems to maintain the prescribed limit for particulate emissions of 1.1 k (coefficient of absorption).
The installation of the Eco Saving pin from the community action took place on 10.13.2013 after I had successfully tested the pen in my lawn tractor over the summer.
Originally I wanted to unsuscribe the car due to the exhaust problem, but the value had improved by 88% from 0.98 to 0.12, incredible, and I was easily able to obtain a positive opinion on the MOT inspection on 04.11.2014.
In the meantime, I have bought two pins, one of which works wonders, exhaust, engine performance and fuel economy have improved significantly even at my Audi A4. Super! (2014)
