From time to time on start up I am getting the ABS fault light on!

This will reset after turning the ignition off and restarting the engine - but starting to worry on how many ££££££s this is going to cost

Are there any easy not too expensive checks / tests I can perform without going to a Saab agent and having £££££££ extracted from my wallet?

Not causing a problem at the moment - just a bit .......... after spending months getting the car to run and look great to get a big triangle light up on the dash is a bit of a dissapointment. or is that just old saab ownership?

Could be little more than a dodgy relay, are you moving before the warning light comes on? the abs sensors are little more than hall effect devices and if there output is weak then the system will switch off [but the car needs to exceed 4mph for the diagnostic of the sensors to be performed], but if it doesn't come on at all sometimes then a relay perhaps.

Don't go to a dealer with this, find a good Bosch ABS specialist [for me in the Midlands it's Carwoods, you must have somewhere similar] My sister ABS on her Cavalier went south, it was the surge arrester relay.

Had a similar problem on a Citroen BX a few years ago. Turned out to be an intermitant bad contact in one of the plug/sockets that joins the sensor to the wiring loom. I cleaned each of the 4 connectors with switch cleaner and bingo no problems.

I don't know where the connectors (plug/sockets) are on SAABs but they can't be too difficult to find. The rear ones on the Citoen wre under the rear seat.

Might be worth a try.

Poor contacts due to age/corrosion are common for probably all cars.

Check the four hub sensors and their connections at the wheels.
More get out and crawl under...
