what a pain that was to get the old sensor out ended up applying a lot of wd40 alot of brute force then a lot off red hot heat and a whole lot more of brute force, ended up with a bar about 4 foot long and managed to just get it to turn, then lots more wd40 and tightening and untighting until the ould one was out , took about a hour , the new one screwed in by hand and a 22mm open end spanner got it in the reconnected and started car , running a lot smoother also idle is loads better and response is better , i was hoping engine light would just go out but looks like it needs a reset, any one local to Doncaster that has the gear or am i stuffed to take it to fiat??
