Hi

Just wondered if anyone can advise me what the problem is with my smart fortwo 2006.
The yellow warning triangle is on constantly & I have no hill start function.
On Monday of this week I hit a spillage on the road and the car just spun with no warning which was very frightening.
I do not have the traction light showing due to the yellow triangle with an exclamation light showing.
Any thoughts as to what it can be?
I did have it put on the machine and they said it was the steering sensor but wanted to see what anyone else thought.
Many thanks
