3.7 litres in the case of a Carrera 2, 3.8 litres for a Carrera 4. The front differential takes 1.2 litres of the same oil.

75W/90 Gear Oil conforming to API classification GL5. The same oil is used in the front differential of the Carrera 4.

The combined PDAS/ABS alarm (on Carrera 4 only) can be caused by simply not waiting for the high pressure pump to build sufficient pressure in the braking system before driving off. There have been instances where spurious high voltage leakage from bad ignition coils or cracked distributor caps have caused similar problems. The PDAS system is also very sensitive to battery voltage and hydraulic fluid level and these should be checked first.
