I am soon going on a long drive down to S W France, probably around 2,000 + miles. I get the MV6 serviced regularly. Very recently had new coil packs. I sometime read here about crank sensors failing. Just how frequent is this ? Should I get it replaced before going ? Are they expensive ?
-
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.....
-
..... Just how frequent is this ?
Not very, but having a spare when in Deepest France could very well save you a day or so of waiting for a new one. French only really do French cars. Many years (15 ?) ago, my V6's exhaust failed very noisily, I calledinto a Feuvert ... a French Halfords .... and they wanted €700 for cheap Bosal exhaust
Should I get it replaced before going ?
No, just put a genuine spare in the boot, just incase.
Are they expensive ?
Cheap, pattern sensors are very cheap, but IIRC my OE from Vauxhall was more like £70 (I think)
And failing crank sensors does affect 2.5/3.0 as much as the later cars
-
I believe you have, but worht a mention:
Check plug wells for oil (leaking camcover seals) -> IMO long trip could ruin HT leads which are deteorated by oil, but were still working perfectly fine before the trip.
Also, check your scuttle for leaks -> if it leaks, on heavy rain, quite a lot of water drips all over the DIS pack. Hot DIS pack and cold water is not a good combo.
One more thing -> HBV - they fail sometimes, spraying cooland around the back of the engine. Again, DIS pack.

Helpful. Thanks :y
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. As far as I know mine has never been replaced and I'm at 115k. I did much the same trip last year without any problems, but I'm a pessimist ???
-
I carry a spare new crank sensor in the boot all the time, takes up very little room, and is actually very easy to change.
Most things that fail on the Omega are "bodgeable" to a certain extent, or pattern parts can be used to get you home.. but a failed CS means the engine stops and will not run.... end of story.... and getting hold of a GENUINE GM spare may be somewhat difficult, especially in France.

Exactly my thoughts. I'm getting it changed before going and hanging on to the old one as a spare. I've had a sensor fail on a previous Omega. Yes' it just stops :(
It may be easy to change for car DIY-ers, but I simply have no idea about even where this is or where to begin. I do none of my own work. So my local independant garage is doing it next week, with genuine Bosch part.

If you`re driving to France no doubt you will have some form of breakdown cover, so as long as you have the part in the boot then they will be able to fit it for you at the roadside :y
-

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. :y
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. :y

You might want to check that with TheBoy. ;)
All V6s are prone to crank sensor failure.

Is this genuine GM?

Well, I think so. My mechanic said that Bosch is manufacturers part, and this seems to

You cannot remove all of a original crank sensor.
-
Changing it involves getting under the car. I suppose I might manage to raise the n/s front wheel high enough with the car jack to get the spare wheel under it, then crawl under the car. Is that the recommended technique?

I think this is good advice Rog! :y 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 :y.
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.

Rog dosn't do DIY. ;)

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 :(
-
What recent work? :-\

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 ;) ;)

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.
-
Plugs and or coil packs being the likely root of the running issues... probably summat either not plugged in correctly or disturbed in process of changing... especially if all ok before :-X
