What’s the cause?

Asked by Catrachicano May 27, 2018 at 04:31 PM about the 2008 BMW 3 Series 328xi Sedan AWD

Question type: Maintenance & Repair

I just got my DM W recently and I filled up a regular
gas and a service engine soon light came on about
a day later, I went to an AutoZone and they checked
it out in a code P0442 came up I’ve talked to many
people and told them I filled it up with regular gas in
said to them that the minimum required is 91
octane.Is me filling it up with regular gas the cause?

1 Answer

I’ve removed the gas cap and tightened it and still the service engine soon is on, Ive seen videos and people just replaced the gas cap. Is that what I should do?
