DSC, Dynamic Drive, Speedo, ABS, Servtronic TV Faults

There seems to be quite a few posts on similar problems but no clear resolution
My faults started with a parking brake error which went on for about 2 months. I check the cables and drive cogs but all was fine. Then I had a DSC failure which added to the fault, the steering felt very light with this error. Then at random I had a Dynamic Drive Fault, usually present when the engine was warm. With this fault the speedo died and when I looked at the secret menu on the instrument clusted the momentary speed read 409.7 kmhr even when stationary. The TV also assumed that the car was mobile when actually stationarry and did not turn on. With the Dynamic Drive error the ABS fault indicator comes on and the reversing sensors stay on.
Is there a logical trouble shooting process, I feel it may be a sensor and not a series of faulty modules. All help greatly appreciated.
Car drive fine though.
Regards

I would guess something to do with your wheel speed sensors / the DSC control module.

Everything that is not working is linked to the speed of the car, so I would check there first.

Sounds like abs module or a bad alternator. By the way how is the supercharger mod going. You left everyone hanging on the final results and sound clip.

Sorry for the lack of posts, just been consumed by work.
I have not fixed the faults yet but soon.
The car has great power, still fumbles when cold but when it goes, it goes well.
I will change out the plugs soon and see if we can tweek a few things.
I do find that there is a long lag in changing gears when under power.
Will do a sound recording soon as well
Regards
Giz
