A second angry DaimlerChrysler German shareholder group on Friday urged the company's chairman to quit in a growing fight over who is to blame for a sudden slump at the US-based Chrysler arm, Associated Press (AP) reports.

Critical Shareholders DaimlerChrysler, an umbrella for small shareholders in the German-US company, demanded the immediate resignation of chief executive Juergen Schrempp, saying he has cost them 70 billion marks ($US30 billion) in lost stock value.

The move rides a wave of US lawsuits that has rocked the Stuttgart-based automaker, including a $US8 billion lawsuit filed last Monday by US investor Kirk Kerkorian, DaimlerChrysler's third biggest shareholder.

A few days later, another group of German shareholders said it would formally petition DaimlerChrysler to fire Schrempp and dump its loss-making Chrysler division during April's annual shareholder meeting.

Adding to the acrimony was a DaimlerChrysler board member who suggested that American executives withheld weak financial figures during 1998 merger talks between Daimler-Benz and Chrysler.

"Apparently, Chrysler did not make available to us all the decisive figures during the merger's preparation stage,'' supervisory board member Manfred Goebels theorised in an interview with the business weekly Wirtschaftswoche. "Perhaps our production experts were confronted with too few transparent facts during their analysis of the Chrysler plants.''

But Goebels stopped short of saying merger mastermind Schrempp got duped. Schrempp is in solid control, Goebels said, adding that the fundamentals of teaming up with Chrysler were still sound.

Analysts said there is little evidence that Chrysler hid poor figures, adding that the financial troubles at Chrysler, which rocked the partnership when it posted a $US512 million loss in the third quarter, sprang up later in the game from fierce competition and tight profit margins.

"I don't see any signs of that,'' Juergen Pieper, an auto analyst with Metzler Bank in Frankfurt, told AP. "Chrysler had done almost everything right for a couple of years, and they were simply too slow in reacting to the competition that moved into their markets.''

Until the third quarter, the US-based Chrysler unit had been a cash cow, delivering half the profits to DaimlerChrysler with its popular minivans and sports utility vehicles. When other automakers rolled out similar models, DaimlerChrysler had to lure customers with bargain promotions that ate into profits.

DaimlerChrysler shares were up 4.5 percent to 46 euros ($US20.50) in Frankfurt trading on Friday, but they have lost about half their value since peaking in 1999 at a post-merger high.
