Audi A3 Common ECU fault

Audi A3 engine ECU fault

This 2003-2008 Audi A3 1.9 - 2.0 TDI ECU is a very common failure. The ECU is manufactured by Bosch within system type 'EDC16U1'.

 

The failure is a well-known common issue for the Audi A3 and will prevent the engine from starting when the failure occurs. You may find that the fault is intermittent in nature to start with but then becomes a permanent failure soon after. Sometimes turning the ignition on and off in quick succession may temporarily allow the engine to start but the fault will return once the engine is switched off.

 

You may notice that the engine management light fails to illuminate on the instrument cluster when the fault occurs.  You may also find that your diagnostic equipment will fail to communicate properly with the engine system to retrieve fault code information.

 

These above symptoms are all deepening signs that your engine ECU may have failed. We can test and repair your own ECU within 2-3 working days or we can supply replacement units from stock that are pre-programmed: so there is no need for expensive programming - just simple plug in and drive away. Both options come with an unlimited mileage Lifetime Warranty*.
