Is it an 417A....? It MUST have the A unfortunately.

[Mikes2]

This is a for a late 20v ?

Pretty sure I've got a spare. Will dig it out when I get home and send you a message

[simon20vq]

I've three of them and non state A on the end.
Bosch or Hitachi unit on your car? I thought there were two types 89-90 90-91?
Is the A at the end of the number or embossed elsewhere on the black plastic?

[Bowie69]

Mikes2, yep, a late car, post March 1990

Simon, thanks...... just been out to triple-check the car.... and contrary to the parts catalog it doesn't have an A on the end!

It's a 4-port ECU on the car, and the MAF is Hitachi.

Send me a PM with your paypal address, if that's OK?

Pete.

To update this..... received MAF from Simon 20vq, only done a quarter of a tank so far, seems to be running better, hunting after starting is better so that is a result for sure.

HOWEVER (and this is NO FAULT of Simon), it is actually different compared to what came out. I tried unscrewing the actual sensor from the housing, to swap it over so as not to have to swap the whole housing out, however the earlier MAF is a slightly different shape and won't fit on the later housing. I ended up swapping housings over.

I think I found what the 'A' means, even if it isn't marked with it!

Anyways, looking at the two parts, there is a panel under the part number that has a couple of other markings on it. On the pre-march 1990 it reads as:

AFH50-01B
0112

and on the post-march 1990 MAF it has:

AFH50-12
0X26

So they are definitely different, and it has had a positive effect on the running, but not quite the right one (as above, I am not apportioning blan to ANYONE but me!).

Anyone know the difference between the two?

And anyone got one with the correct markings for the post-march 1990 system?

Cheers!

All 7A cars used the same MAF - there was no distinction between early and late cars.

Those numbers look like date codes of manufacture

[recurveandy]

I expect the 471A was from a 12v V6

If this is correct then as you Know i have a nice shiny perfectly working one from a Löw mileage car.
Pete to save yourself all the heart ache why dont you try Audi? Or at least ring them and get the part number.

Also listed for the 7A:

As above, the actual MAF when removed from the housing won't fit the other housing, so something is different between the two, just can;t tell if it is important or not. The other significant thing is the testing procedure is different on pre and post march 1990 cars.
