If you're trying to remove the sensor from the aluminium bracket it locates in, it can be a real pain - They get seized in.
I've had to remove the cambelt and cank pulley before, in order to chisel it out.

As Rich says, the corrosion builds up between the sensor body and the oil pump. It'll come out eventually if you keep at it. Tapping it out is the quick option but the sensor will almost certainly be useless afterwards. If you know it's bust already, that's the way to go.

Yep, had the whole alternator off last night not just the cover
Will hav to get another one on standby before attempting again because I think I'm going to end up loosing my temper.
Incidently are cam and crank sensors the same part on a phase 1.5?

What tends to happen is when you twist it trying to pull it out, the 'head' of the sensor turns independantly from the body - Then you KNOW it's broken!
Cam and crank sensors are not quite the same - Cam sensor has an extra sheath around the body of the sensor, and bolt hole is in a slightly different position.

Well I got it out in the end in about 8 pieces. The only way to get them out when they are that well seized is brute force and drilling/breaking it up. Then you can collapse the steel sleeve and pull it out with pliers.
Many thanks to coops1 who sent me a sensor FOC and wouldn't even let me pay the postage, star man!

This saga begs the question... is there any grease or whatever that can be applied to the new one , to make it easier to remove for future oil changes (if you do them the '****' way)? Or will any kind of lubricant adversely affect the sensor's detecting capability?

Well i put a thin smear of spray grease on the replacement so hopefully it wont seize in as bad. I normally just unplug the sensor for oil changes but think in future I will take the whole thing out so it doesnt seize, after all its a 20 second job to undo the bolt. Shame it took me 3 hours lol.
