As the title suggests, I'm after some help in relation to the replacement of my Master Cylinder. After replacing and bleeding the clutch system and brakes my car only comes onto accessory and has the following faults in order. ESP Fault, Parking Brake Malfunction, Headlight Dynamic Range Defective. Was told to check the battery and after replacing that (it was due for a change but not quite gone yet) the car still wont start. Waiting on a ross tech cable to run VCDS on the codes. Any help or suggestions would be appreciated, also already checked the relay box under the wiper system for water or contaminants and it's fine.
