My question is, two days after I got the downpipe install at my BMW dealer, the check engine light turn on ! I was under the impression that these kind of Downpipe were design to not turn any lights on ! Is it the downpipe or the DV+ that turn it on ? Because I got them install at the same time.
Thanks.
