Spoke to the garage and the old sensor was a Bosch.
Not sure what it was replaced with (mech is on holiday) but it defo wouldn't be Bosch. Part cost is way too low.
So, will source a Bosch crank sensor and see where we go. Seen some on Ebay and Amazon tho may just go to local Vauxhall dealer.

A 19 is bad news on these.

A 3.0l sensor from a dealer on Tradeclub is about £50.  Personally, I *ALWAYS* carry a spare crank sensor in the boot, which has saved me the hassle of having to arrange a tow in the past.

Go to a genuine Vauxhall dealer that you genuinely have to walk into in order to buy your replacement. Anything else will be a further waste of time/money ;)

Assuming you have a local Vauxhall dealer that still does parts then phone first. If this sensor was not carried over to another vehicle after the Omega ceased production then it will be obsolete and unlikely to be still stocked. Vauxhall discontinued any remaining Omega unique parts well over a year ago. Anything left was sold off to whomsoever would have it. But you might strike lucky and find one still in stock or it might be available special order from Germany.

Regardless of where you get it, the part you need should be marked on the head with the Bosch logo and the number '0 261 210 131'.
It may or may not also have a GM logo. These parts might additionally be marked 90494182 which is the internal factory assembly number.
The GM Opel/Vauxhall aftermarket part number actually used to identify and buy the sensor is 90540743.

Other parts that have a GM logo and are marked with part number '90 492 061' won't work reliably. These are 540Ω as opposed to the Bosch's 860Ω. These require an earlier revision of the Motronic ECU.

Popped in yesterday to the local dealer.. The part is now on order from Germany n will be here in 7-10days. when it arrives, I'll have a word with the mech and hopefully he'll pop out n fit it for me.

It's V009050743, which I assume is the same as the GM part. Chap at the counter said it was.
Oddly they don't do trade club any more, but he knocked off 10% anyway.

More and more dealers are pulling out of the Trade Club scheme, so I'm not surprised. And in any event since this part is now special order from Germany, it has likely dropped off the TC scheme.
The part-number looks good.
How much did you have to pay?

£80 inc VAT.
The incorrect sensor was half that, and even that took three days to source. It's one if them things that, unless you have specific knowledge, you'd never think. Which is why main dealers charge so much... I trust my mechanic- he's seen me right in the past.

Well, sensor replaced yesterday and everything seems fine.
Drove it for a few local miles, just in case, to bring it up to temp. Hopefully, that's the issue cured.
Have to say, my mechanic was very sceptical that the sensor was at fault.

I have noticed tho that, the date keeps resetting back to 2000 on switching ignition on. Time is fine.
Will this cure itself once ecu clears the fault code?

I can't imagine why, as fitting a genuine crank sensor bought over the counter at a main dealer is SOP for any marque.
