2001-02 Audi B6 A4: moisture may enter brake servo
In 2010, Audi UK issued a ‘non-code action’ for Audi B6 A4 vehicles that were manufactured from 1 March 2001 to 30 April 2002. For affected Audi A4 vehicles, moisture could enter the brake servo (NCA/2010/006).
Problems and faults: Audi B6 A4
- The anti-lock braking system (ABS) may activate unnecessarily under normal to light braking pressure due to cracks in tone/exciter rings (rings on the outer CV shaft that measure wheel rotation).
- When the oil filter is removed, the oil cooler is susceptible to turning – this may damage the coolant lines and cause a coolant leak.
- Water may leak into a wiring harness near the A-pillar, causing problems with the remote central locking, power windows, issuing a ‘door ajar’ warning when the doors are shut and the interior lights staying on.
- For the 1.8-litre turbocharged petrol engine, the throttle body control valve may sludge up, causing a very low or uneven idle.
