Fault codes

Morning all,

Can anyone give any info on these two fault codes?
B1b02 low frequency coil signal not in range
B1c57 ignition circuit monitoring relay short to +/ ground, or open circuit.

My mechanic believes there's a control box that may need replacing but land rovers are not his forte. He believes that the other faults shown on diagnosis are all linked to this box. (Various faults including suspension light, Bluetooth etc).
Does anyone have any experience of this?

Many thanks.

My car has had these fault codes for 3.5 years, with no ill effects

Are you having any specific issues?

intermittent suspension warning light, sometimes the radio doesn't work, that's about all.

A couple of times when the suspension light has come on, the car seems a bit 'wobbly'

C1119 - Hydraulic pressure

Presumably in the ARC/DRM module? Suspect you may have a leakand/or low fluid

Sorry for the long reply, I've been lazy.

The fluid looks low, how high up in the bottle should it be? Near the top marker?
