Hi all, just to let you know all sorted now. I cleaned the
sensor but this didn't help so bit the bullet and took it into my local garage and he diagnosed a faulty
and this has fixed it. £37 for the part and £37 for his time so not too much.
Happy motoring. 967000 miles so far, anyone know what happens to a renault when they go over the 100000? do they just stop?
