Following its presentation of technical measures to the German Federal Motor Transport Authority (KBA) in December 2015 for its diesel engines affected by the NOx issue, Volkswagen has begun recalling and implementing a software update for its 1.2 litre, 1.6 litre and 2.0 litre EA189 engines in Germany. The exercise began at the end of January with the 2.0 litre in the VW Amarok, and will be followed by the Passat.

Once KBA has checked and approved the measures, VW customers will be contacted and informed of the recall. They will then be requested to make an appointment with a VW service partner. The recall exercise is expected to be carried out throughout 2016.

The estimated workshop time for the software update is said to be under 30 minutes. Additionally, for the 1.6 litre engine, a flow rectifier will be fitted in the intake duct, which will take 45 minutes. The new engine control software will bring the EA189 engine in the Amarok up to compliance with the EU5 emissions standard. The automaker claims these measures will not affect fuel economy or performance figures, likewise CO2 or noise emissions.

In addition to the Amarok and Passat, other models with the affected 2.0 TDI engines will also be included. All affected 1.2 litre engines are scheduled to be addressed by the end of the second quarter, with 1.6 litre engines set to be worked on from the third quarter of 2016. The recall for the EA189 engine will commence in other European countries after terms are met with the respective authorities.
