saab 9-3 vector esp light wont turn on

[darren2018]

can anyone help me to find the problem with my esp light. ive been googling for days ive hit a wall. esp light is in the off position when i press the button to turn it on the off icon is still displayed and cycles from that to the orange info i. the top middle warning display is not on just the one on the dash where the clocks are. tried a secondhand yaw sensor and nothing looked at all the abs sensors all seam to be good whats left. it would be a great help if some one could suggest something else i could try.

ABS module could be on the way out in that case you can buy a rebuild or sending yours to a reman ..Do a search here for a DIY you will find you can even drive without it

will that need programming because you can get one on ebay for cheap
