German carmakers continued to struggle with problems related to faulty diesel injection pumps produced by Robert Bosch on Tuesday, with companies such as DaimlerChrysler and BMW saying they were having to temporarily halt production. A DaimlerChrysler spokesman said that production at its main German production site, the Mercedes factory in Sindelfingen, would be shut down next Monday and Tuesday as a result of the problem, which affected fuel pumps made in December and January. Last week, Mercedes' main rival, luxury car maker BMW, also said it would have close its factory in Dingolfing. On Tuesday, BMW said it would recall around 13,000 cars affected by the fuel pump problem. Audi, a unit of Volkswagen, also said it was suffering from bottlenecks. Bosch, the biggest maker of car parts in the world, said it hoped to solve the problem quickly.
