BERLIN, Sept 25 (Reuters) – German auto group Volkswagen will recall around 4 million vehicles across ​four brands in the biggest such ‌action since the Dieselgate scandal, the Handelsblatt newspaper reported on Friday.

Some 2.16 million VW ​models and 700,000 Audi models are ​to be recalled, according to Germany’s KBA ⁠road traffic authority.

Handelsblatt reported that the ​action also included over a million ​vehicles at Volkswagen’s Czech brand Skoda and 200,000 at Spanish brand Seat.

Seat confirmed the number. Skoda ​had no immediate comment on the ​report.

In an earlier statement, Volkswagen said customers had been ‌asked ⁠to take their vehicles for repair because of the risk of corrosion involving a screw in the steering system. ​If unchecked, ​this could ⁠compromise the steering’s function in the long term.

The company stressed ​that the recall was a ​precautionary ⁠measure and said the replacement of the screw would take no longer than an ⁠hour.

Volkswagen ​declined to comment on ​the estimated cost of the recalls.
