Hi all
Over the weekend four error codes randomly appeared on the dash.
Just a bit of background, car is a c220 cdi, 75k on the clock, it's regularly driven on the motorway. In recent months the start/stop hasn't worked which I ignored. I've heard the stop start is based of the Aux battery and if that is out then you may receive multiple electric problems/fault messages, am I on the right tracks!? I don't see the main battery or Aux battery being changed from the service history of the car so my only thoughts are one of these

See attached images, what could possibly be the issue?
Thanks for reading
Ravs

Hi, as you mentioned I'd be looking at battery 1st. May be worth disconnecting both for 10 mins and reconnect to see if they go.

Don't seem related either

Thanks both. I've ordered a new main battery for £140 (Bosch) with a shot that it might be that.

Upon checking the battery over the weekend I think it's the the original (factory fitted) - The car is a 2011 reg.

wouldn't all those codes come up if the ABS was unhappy (wheel speed sensor or module fault) ?

You wouldn't get airbag warning I'm pretty sure.

The airbag is another issue that occurred a few weeks ago and is unrelated. I pushed the front drivers seat to hard one day whilst vacuuming the rear which caused a temperamental fault code with the "Front Right Malfunction" , I believe the seat belt needs replacing.

In which case the rest are as suggested highly likely to be a bad wheel sensor.
