Saab 9-5 Aero. Currently away on holiday on Anglesey. On the way here, light braking for an exit slip resulted in ABS actuation, followed by a warning tone and dsc/ABS/brake warning lights. The speedo continued to function, but the cruise control stopped working, the SID was reporting an average speed of 2 miles per hour at 3 miles per gallon. Boost was cut to half way through the amber section. Since then it has reset itself several times and driven normally for a while before repeating the performance, though without the spurious ABS activation. It's also lost the speedo once, though a restart cured that.



Sounds expensive?

May or May not help but...

My 93 has just been in due to a noisy wheel bearing. The garage (Saab Tec in Glossop, Derbyshire) had major problems at first removing the drive shaft from the hub but once they'd sorted that, fitted the new wheel bearing etc it then came up with abs warnings. Turns out the abs sensor is part of the wheel bearing assembly and this was faulty in the new one, they had to remove the bearing (again), fit a new sensor and put it all back together again.

Final bill was £205 for a new bearing, used cv joint (as the original was seized) and labour.

If it is fixed as cheaply as that I shall be very happy!

If it started with an abs warning could be as simple as just a sensor..hopefully.

Good luck with it.

The abs module can be a common fault on these models, i have two 9-5 aeros and my daily driver has the same lights on as yours, although they are intermittent and dont always come on, have beeen told by local saab specialist it is more than likely the abs module, which is a relatively easy quick fix. I will get round to fixing it at some point.

The ns/f ABS reluctor ring can be spun with a fingertip, which, and call me Mr Picky, is not right. So it's in the garage today having a new one fitted. They said 30-60 mins labour depending how much disassembly is needed to fit it, I supplied the ring which cost me £25 delivered.
