Audi A4 A6 Multitronic auto transmission ECU

Audi A4 A6 Multitronic fault

Audi A4 A6 Multitronic gearbox transmission ECU (“PRNDS” light fault)

 

This Audi A4 A6 Multitronic Transmission ECU is very common for causing failure for all Audi 2001 - 2007 vehicles with Multitronic transmission/gearbox.

 

When this gearbox ECU becomes faulty, the P R N D S lights will flash on the display instead of just the “D” icon when driving. This will generally be your first indication that there is something wrong. As soon as the P R N D S lights begin flashing the vehicle will usually be forced into fail-safe mode and lose power.

Other common symptoms include a complete loss of reverse and drive, with the transmission not being able to move from the P position.

Scanning the vehicle with diagnostic equipment will often reveal a host of fault codes relating to faulty range, output and input sensors along with codes for solenoid and pressure control valve malfunction.

 

The Audi main dealership remedy to this Multitronic issue is to purchase a new transmission ECU from manufacturer: at a huge expense.

Our solution is far more cost-effective: we test and rebuild your own Multitronic transmission ECU, at a fraction of the cost of the main dealer unit and provide a Lifetime warranty. After the rebuild this Audi gearbox ECU will just plug straight back into the gearbox with no need for programming afterwards.

  • P R N D S light flashing on dashboard
  • Gearbox in fail-safe mode / limp home mode
  • Loss of reverse gear
  • Complete loss of drive
