It’s about a Lupo (year 2002) with 1.0 MPI engine (50 hp) and 151,000 km. Unfortunately, the TÜV has something to complain about and even though I didn’t even get a diamond for 106.26 euros. According to the test report, the MIL is not working (so it doesn’t glow). There should also be something in the fault memory. The EPC LED is ok, however, fuel consumption is also 5.5 liters (city), engine is also running round. What can I do now? Did the Lupo have this exhaust warning light at all (supposed to look like an engine with the word check)?
