Mercedes R230 electrical issues

[absEL]

Hi Guys,
I’ve got an SL350 that’s throwing up error messages - ESP malfunction and now won’t start.
It had low battery and key is not working to remotely open car. It cranked ran for a good run then came back and wouldn’t start again.
I need a star unit in Sheffield - any recommendations - saw a thread by Flango hopefully if he reads this he might be able to point me in the right direction.
P2300 came up as one of the codes.
Thanks in advance
Abs

Most likely candidate is a flat battery triggering a low of false OBD error codes.

Has the car been relatively unused, or only been used for short runs will full lights and AC?

Step 1: charge / condition the battery (if you can run a mains cable to it) or get a new battery.

Step 2: get someone to check / reset the codes

It “might” be that you’ve also got water in the spare wheel well. Pop the boot and check if the foam in the boot is wet
