Stability control failure, abs malfunction & traction control failure

[alanaberdeen]

Hi,
I'm new to here but I'm looking for some help.
I have an 2005 Saab 93 Vector Sport 1.9 tdi
About a month ago I got a fault showing "stability control failure", this fault would go away for the next journey then show up again and so on....
Then last week it has been staying on all the time, but yesterday "abs malfuntion" & " traction control failure" came up.
Now I'm getting worried!!!
Can anyone shed any light on these faults for me before I go to the expensive dealer at this time of year!!

Thanks in advance

Alan
