Lately I am having the following problems:-1. The acceleration is kinda sluggish if I go slow on the throttle pedal. On the other hand, if I floor down the pedal, it leaps off fairly quickly but then the rev counter keeps climbing up past 7000 RPM and the gear refuse to change to second (or change very, very late). To correct this I have to bring the car to a standstill and start over again but at the earlier mentioned sluggish pace;2. Occasionally when braking the whole car shudders and judders to a stop;3. Fuel consumption has been unusually high of late.The ABS and DSC lights have also been playing up but I am not sure if this has direct connection to the aforementioned problems. Reading through the forums there have been suggestions that either speed sensors, camshaft sensors and/or vanos seals could be the culprit.Is this correct or if not what other things should I look for?Appreciate your comments and inputs.Thanks.Cheers & best regards,Zaim Al-AminBMW 525i WXY 2005Group Legal AdvisorSigur Ros Group of Companies+60192082005 (Malaysia)+905492212005 (Turkey)</p></blockquote><p></p>
