Hi all,
I hope that you can help me with my Lupo AUD 1.4 from 2002. It sometimes goes into some kind of emergency mode, mainly after long drives. Then a strange clapping noise comes from the exhaust. It won't accelerate anymore. After a wait it will drive normally again after shutting it down.
I've thus far replaced both O2 sensors, the catalytic converter and the spark plugs. It shows error code P0441 and P0134. In t video you can hear the strange noise.
Any help and suggestions are welcome!
Thanks!
Rolf
