Volkswagen Group has received the green light for all fixes proposed  to TDI engines in the wake of the dieselgate emissions scandal.

The German manufacturer confirmed in a statement published this morning that the German Federal Motor Transport Authority (KBA) had given it the go-ahead to implement the changes to diesel models with type EA189 engines.

It stated that the Group's various brands would notify vehicle owners in the weeks ahead, allowing them to make an appointment in the short term to have their vehicles modified at an authorized service centre.

Volkswagen Group's statement said: “The Federal Motor Transport Authority has confirmed that implementing the technical solutions for the affected models will in no way adversely affect fuel consumption, engine performance or noise emissions.

“Once modified, the vehicles will also meet all legal requirements and the applicable emissions standards.”

Volkswagen’s latest wave of engine fixes will be applicable to 1.2, 1.6 and two-litre engines from the E189 diesel family that were among 11 million engines sold worldwide with software designed to cheat tests for harmful NOx emissions.

The 1.2- and 2.0-liter engines will get a software upgrade that requires about 30 minutes workshop time.

The 1.6-liter engine will require the installation of a piece of mesh to regulate air flow in addition to a software upgrade.

Volkswagen said that it has worked intensively to implement the technical solutions and will modify all vehicles affected by the NOx matter, adding: “Customers will incur no costs for the implementation of the technical measures.

“As part of the recall process, all customers will also be offered an appropriate replacement vehicle free of charge.

“Implementation of the necessary technical solutions is being carried out throughout Europe in accordance with the timetable and action plan coordinated with the Federal Motor Transport Authority.”
