hey guys, i'm looking to all you with more experience than me for any help at all..
at the weekend myself and my dad (who's a 'retired' mechanic) took on the task of servicing my car (a4 tdi 130 B6) for the second year.
only difference this time was the changing of the brake fluid.
everything went smoothly, but on test drive we noticed the following two problems;
1) brakes.. first push of lpedal ok, second time we get a rock solid pedal. also if i brake heavily in order to test the abs function, the car just comes to a stop eventually with no intervention. with the car off, if i pump the pedal till its hard (only 1 or 2 times), and fire up the car the pedal remains stiff which would signal a servo fault? i think!
2) performance.. the car is now also very sluggish, with flat spots. it could be at 2,000rpm in 3rd gear, and putting my foot to the floor does nothing... also if i hold my foot on the brake (whilst stationary) the accelerator does nothing, i can floor the accelerator yet the engine does not rev up.
are the two connected? we've tried another vaccuum pump to no avail...the next step would be the servo (which looks like a tough job)
could it have anything to do with how we bled the brakes?
any help greatly appreciated!
