I recently had a 75k service on a 2009 CW Diesel. When I picked the car up from dealer I noticed that the brake pedal was up high and after driving several kilometers the brakes appeared to be binding. After pumping the brakes for a while the pedal seemed to settle down for a while. On going down a hill I took my foot off the accelerator and the car came to a stop with out my foot on the brake. I took it back to the dealer and they thought it might be an ABS problem but after tests seemed to think it was contaminated brake fluid. When the car was serviced they replaced the brake switch as a manufacturer recall. After replacing the brake fluid I still have a high brake pedal sometimes and economy gets up to 11-12 litres /100 sometimes. My question is could it be the switch they replaced causing this problem or could it be an ABS issue. Brakes were fine before the service. Thank you anyone.
