Some time ago the yellow engine warning light came on. I followed the diagnostic procedure (holding down the trip button while switching the ignition on and then pressing it repeatedly to cycle through the codes), but resigned myself to having a diagnostic check done.
Googling shows this is a fairly common problem with Streetkas, and it's usually the lambda sensor at fault.
Left it for a while as the car seemed to be running ok, went on a few long trips (100 miles+) with no issues. As the MOT isn't due until October I wasn't too bothered about fixing it in a hurry.
Checked the tyre pressures today and both rear wheels were low at ~17psi. I hadn't noticed as they're low-profile and it's hard to tell by sight.
After re-inflating them, the engine warning light went out and has stayed out since.
Is this normal?
