Only serv light on

[DetectivePenguin]

After bringing the Trophy out of winter storage last month I was greated with a dashboard of Christmas tree lights. I ended up replacing the rear ABS sensors and the O2 sensors and the Trophy was happy again.

Recently the SERV light is staying illumated while driving. While I try and fix my Renolink laptop, does anyone know what to check when only the SERV light stays on.

All other lights still work and turn off after the car starts.

Seen that happen when the sensor in the interior light is unplugged.

But i'm sure that's not the case here.

Too hard to say without scanning. Can be on for various faults, even low oil iirc.
