Help please
Hi all. The engine management light has lit up on my 2016 q5(103000 miles). First came on Friday night, went off after cleaning the air filter on Saturday. Filter was disgusting, so bought a new k and n one. After replacing Monday, the light came on again and has been on ever since, even after changing the air filter back. Have a mate with a computer which read as above, but can’t get it into my usual mechanic until November. I travel 40 miles to work (and back) each day, so wondered if there was anything anyone could advise that I could do myself, or have had this problem before? Should I replace the ear valve? Thanks in advance.
