2003 Renault ABS light and speedometer problems.

After having some ABS faults a new drive shaft with ABS ring was fitted to my renualt clio diesel
2003.
Following the reair I have an ABS light still standing and also the speedometer does not accuratley reflect my speed.

I believe this could be that the car computer requires resetting as the reair was not done by a renault dealer. I am worried if I take it to the renault specialsist they will try and rip me off. Is this a fault that you ahve heard of.
