Volkswagen has recalled 30,000 Transporter T5 utility vehicles. The company said that wax could have gotten into the steering mechanism and loosened the screws that held it tight, a spokesman said on Wednesday in Hanover. The recall is valid for all vehicles delivered up to December 2003. The problem would not affect the SUV's safety, the spokesman told journalists. VW said electronic air conditioners, heaters and coolers would also be improved in the recalled vehicles. Media estimates put the costs of the recall at up to €3 million ($3.6 million).
