The front wheels/brakes want to lock up.

The brake pedal becomes dull.


We already replaced the Wheel speed sensors and steering angle sensor which had come up in the codes.


This car is mafless...........anyone have this issue??

You need to run full diagnostics on the car using Durametric or a Porsche diagnostic (i.e. PST2, PIWIS, or PIWIS 2).

Everything is a guess without fault codes provided by any of these tools.

If you have an engine misfire then you have fault code(s) or pending faults.

Either your Durametric needs updating or you need to find a Porsche diagnostic tool.

Engine misfire? Who said anything about that, this has nothing to do with the engine and we have the pro durametric all up to date.

Anyone else that may have had symptoms like this? Thanks

When the front or rear brakes spontaneous jam without there being worked on, is the hydraulic part of the ABS suspicious, calipers will get stuck mostly separately and noth both at the same time. This kind of problem can not be checked with a diagnostic device, this is best done manually. If there is already worked on the brake system, there are obviously a lot more possible causes.

I think Loren read...mafless...and thought misfire...I know he reads a lot of posts.  I'm with RFM...I would inspect the brakes physically (mechanically).
