But I may just get it replaced and keep the existing one as a spare. I read here that they can fail after 100k miles.........

Entirely your choice obviously, but I'd go with a genuine spare in the boot. The reason being, one of my crank sensors lasted over 60k miles and another lasted less than 20k miles. They were both genuine, purchased over the counter at my local Vauxhall dealer.
Another reason to take a spare in the boot is that, if you believe the one on there to be original, the garage will just cut it off, as the original is wedged behind pipes. I've tried to remove them intact but the heat shield around the cable is wedged between the pipe and the engine block, making it nigh on impossible to remove without damage. A garage won't mess about, they'll snip it, yank it out and fit the new one, leaving you with no spare. 
Be handy if someone close to you could show you where it is to make it easier for you in the event that you need to change it. 

I think this is good advice Rog!    Install your new sensor in the boot.

i carry a cheap one in the boot as a get-me-home.  my original failed at 90K but with hindsight there were warning signs - the occasional failure to start on the first turn.  always started perfectly after i put in a new Delphi sensor, 5,500 miles so far . 

when it did fail completely the car started and drove home after resting 2 hours so you might get a grace period but don't count on it. 

my 2.5 engines never had a crank sensor failure, 60K on one 120K on second.

Or maybe both ? Obviously more expensive, two new sensors, but maybe worth it if it provides that confidence factor. Certainly worth it if the worst happens.

You could buy a new sensor and fit it yourself, and leave the original sensor in place, hanging on its cable. On my first V6 Omega I changed my crank sensor in a vain attempt to cure a stalling fault, leaving original sensor hanging. When I eventually cured the fault (MAF sensor) I replaced the original sensor and kept the new one as a spare.

When I were a lad, my cars were always near wrecks and financially, self maintenance was the only option. I spent many a "happy" hour under a lean-to in the freezing cold struggling to do something. Not just stuggling to do it but strugglling to work out actually what to do. I remember fitting a new exhaust to my Austin Westminster A110. I simply could not get it to fit and became convinced that the part was the wrong one. I removed everything I had done, went back to the shop to be told that a section that attached to the manifold was flexible, simply bend it to fit.

A bit later I changed jobs and had a company car. BLISS ! I've never cared much about what the car was, all I cared about was that somebody else did the repairs etc. I don't have a company car now (an Omega company car !) but I have no intention of crawling around under cars getting covered in grease not having any idea of what I am doing. Even recently I fitted a replacement roof aeriel, all ok BUT car I get the inside roof re-fitted ? Can I hell. Been like that for a couple of weeks now

Mine went at about 110k. I found it a reasonably easy fix. I managed to remove as a whole but you will need to tell your garage you want to keep it as a spare....Double tell them!

Tell the garage to fit a new crank sensor, routing the cable clear of the exhaust and with enough slack to accommodate engine movement; leave the old sensor hanging on its cable at the bottom, with the connector loose at the top. Then it's easily reinstalled in emergency.

Took the car for a drive today. It's running like shite with engine management light on and off, no power, undriveable. I don't really care about comments about possible fixes etc. I intend driving to France on Tuesday. There's a possible quick purchase of a 2006 Volvo XC70. I might just go for it. Can't be arsed with friggin around 

[Doctor Gollum]

What recent work?

[steve6367]

Crank sensor is usually just a problem limited to the 2.6/3.2 engines.... not normally a problem on the 2.5/3.0 engines...

It wouldn't harm to get it replaced, if you feel it might need it - just in case, but hen Id be inclined to replace evry sensor too....

Just make sure you have Euro cover with the RAC/AA/Greenflag.....

Failed on both of my 2.5's - I don't carry one anymore as they are both now < 10K GM. Both originals failed at 100K ish.

Problem sorted. However got a decent deal on the Volvo, so I've bought it and will be driving it to France tomorrow (fingers crossed). I expect to be putting the MV6 up for sale here when I get back. It would be hard to justify keeping it

So . . . . . . I will need to get my post count up to use the "for sale" section         

[Doctor Gollum]

An expensive solution and you didn't answer my question...

[Mister Rog]

An expensive solution and you didn't answer my question...

Point taken. But TBH I've had it in mind for some to change anyway, I just needed a bit of an excuse 

Recent things done

Brakes
rear tyres
Crank sensor
Plugs
Coil packs
probably few other bits and pieces

Also bodywork has picked up a few scrapes etc from parking bollards etc, nothing really serious like big dents, but still looks a bit tatty. If I did DIY it would probably be quite easy to do, but I just don't have time.

I'll be providing details and pics in a few weeks when I put it into "For Sale" section

I've done it now. Picking up Volvo tonight or maybe tomorrow AM. Took it for a short drive before deciding. A bit "remote" feeling, but otherwise great. My Mrs will be happy as she always said that the MV6 was like sitting in a sports car. Volvo is like sitting in an armchair.
