Repair messages – help needed please
CITROËN C4 CACTUS

Citroen C4 cactus, 69 reg. 14200 miles on clock.

The spanner light came up and I got warning messages saying

ABS braking system fault. Repair needed

Hill start system fault

ESP/ASR system fault. Repair needed

The car is an automatic and when it has been parked for any length of time, even a couple of minutes, when you press ‘start’ it jumps as if the brakes were locked and suddenly freed. It’s really frightening – it jumped so badly that it almost hit the wall in front.

My local garage cannot seem to find out what the fault is but the main dealer can’t fit the car in until 22 DECEMBER!

I cannot be without a car for that length of time due to mobility problems so am reaching out to see if anyone knows what this is.
