After developing a MAF problem, I started the hunt for a new MAF. In the end I searched ebay for the part # 0281002184 and I found something interesting......
The 2.6 MAF on the veccy is also the same part number and part as one found on some transit vans. I know this may not be much use to most people, however for testing or in my case price reasons, the transit MAF is a direct replacement. Also might make scrap yard trips easier!
Please don't ask me which vans have one of these on, I don't know. All I know is I searched for the part number, found one from a trany van, and it works well.
Hope this helps (someone)!

Uhm, good find :y :y
-
Yes great find :y :)
-
Yep, standard off the shelf items used by a few manufacturers.
The secret to finding MAF's is to;
1) Search ebay for the Vx part code (search listing contents)
2) From the listing get the manufacturers MAF reference
3) Search against the manufacturers reference (again search listing contents).

Thats a worth while addition! Also I believe the 3.2 MAF is the same part number.

And you can get them new for reasonable cash on ebay (some of the mega cheap ones should be avoided)
-
I should add that the 2.6 and 3.2 are the same part
-
noted. Thankyou gents. :y

I was hoping someone else would have asked by now but no, looks like it's down to me.....
What's a MAF then? :question
-
Mass Air Flow sensor
The engine needs to know how much air (as in number of molecules or mass/weight) is entering the engine in order to add the right amount of fuel.
The weight (mass) of air changes continualy with temperature and humidity .... "wet" air weighs a lot less then "dry" air ... which is why when the atmospheric pressure is falling the weather is getting worse ... it contains more moisture .. :)

I will also add....
The 2.6 and 3.2 MAFs have a temp sensor as well. Apparently no temp sensor on 2.5/3.0 MAF.

Seperate on the 2.5/3.0.....and often a good way of telling the MAF on a 2.6/3.2 is buggered (look at the air temp sensor live data)

Hi,
I found this thread interesting, if only to check on ebay to see the great difference in price for what appears to be the same item.
I followed Marks DTM advice and checked the IAT showing on live data and on my motor it shows variation from 29 to 38 deg C according to engine revs with a steady outside ait temp of 10 deg C
I presume from this that there is a fault with the MAF although the car seems to me to be running perfectly OK.
Should I fix something that appears to not need fixing??

The air intake is just in front of the the radiator. When the car is moving forward it will get cool air but when you are reading live data your are probably stationary so an air temperature of 38 degC might be perfectly accurate :-/

should be closer to ambient with the engine running....would be higher due to heat soak if the engine was stopped

Just occurred to me that as the Omega runs two fans if the Climate system wants them so you do get airflow even when the car is stationary.
Don't know if Big_Rogers fans were running :-/

Hi,
I understood from the reply by Marks DTM that the MAF incorporated it's own air intake temperature. This is what I thought would be giving the actual engine air intake temperature for the ECU to perform it's calculations on air mass entering the engine.
I am aware of the sensor just in front of radiator to give the reading on the Dashboard.

That is true, I was pondering on whether the air drawn into the air filter and then through the MAF was being heated up due to the proximity of the air intake to the front of the engine radiator.
When you lift the bonnet on a facelift the air intake is right in front of the radiator, it isn't so easy to see on the pre-facelift (unless you take the grille off).
