Just buy a fault code reader, should be around £20. Then if you get any fault codes just plug it in and it'll tell you the fault number for you to look up. Then instead of going to garage that you have to pay to find AND fix the fault you can just tell them whats wrong and get them to fix it! (Or if its a simple fix do it yourself

)
I know on my Prelude we can bridge the service connector pins with a paperclip and turn the ignition on, if there are any stored faults the light on the dash will flash (4WS, ABS/TCS, ECL) and you just gotta count them. Don't know if it works that way it a Saxo though!
*edit* wooah old thread

Didn't look at the dates, I assumed it was recent seeing as it was near the top
