Pressure increases to slowly normally relates to a leak in the pressure reservoir.

It should do a self diagnostic on start up, If no problems the lights go out. There is an amber and a red warning lamp next to each other relating to the brake system

indeed, but was also wondering if the compressor is knackered, hopefully the op will come back with the pressures

also don’t know if it drops overnight , what type of compressor , question then of leak on dryer cap ??

plus us long term LZ members know these systems so well now , all good fun these suspension systems are, lol

Normally one of- compressor, pressure reservoir, or valve blocks.
Wonder if relay was changed with compressor?
If a different compressor than original the car needs telling so in diagnostic.

I’m thinking, no fault on car self diagnostic at start up,
No fault code on data
Hand brake is working
