Hi - New Driver and New A2 owner here...

@Andrew
Good work.
Any idea how the two different systems relate to year and engine type?
As the FSI was a later model, maybe all FSIs are MK60.
Mac.
Apology for tardy reply.

Not my good work I was quoting.

As to the question of MK60 replacing MK20 by engine type I have no idea, but I have seen a general date of 2003 suggested for the change over although I think that is a little late on the grounds that my 52 FSI plate has MK60 and that I assume would have been built in the summer of 2002. Yes, I suspect all FSI's have the later MK60 but I suppose the definitive answer would be from 7zap if only I understood the meaning of 'F 8Z-2-013 001>>8Z-3-018 750'

"if only I understood the meaning of 'F 8Z-2-013 001>>8Z-3-018 750'"

Andrew, these define the VIN range that the part number relates to, the '-' representing a wildcard character. Here's an example overlaid on a complete VIN: WAUZZZ8Z62N013678
So the table shows that the F suffix part was only fitted to cars with VINs ending 001 through to 750, prior to 001, the part number had no suffix (item 3), and after 750, suffix H is fitted.

I hope this helps.

Apologies for the tardy reply.

Thank you for taking the time and detail of your reply, particular the wildcard '-', things are a lot clearer.

My car WAUZZZ8Z73N019265 has a MK60 part number ending in G so if needed the H version would be the replacement.

Hi all,

So an update on my brake pressure sensor replacement surgery, it is (as I should expect) taking longer than expected ? and I am currently kicking myself and feeling quite foolish and my wallet is getting lighter...

I will probably share more details later but in general, first of all, it's quite a nuisance getting to the sensor even though you can see it quite clearly even grab it with your hand, there's seemingly no way to get it off without taking the whole master cylinder out.

I suppose all in, it's about a 3 or 4 hour job, detaching the master cylinder replacing the sensor getting it all back in and bleeding the brakes.

After all that I switch on to check VCDS and lo and behold .... no sensor detected! (of course, at this point I realise I really should have simply tested the sensor by plugging it into the electronics before doing the whole job just to make sure it worked - WHY did I not do this! :mad:)

On further inspection and research, I have discovered that they used two different sensors for the MK20 and MK60 units, :rolleyes: because of course they did.

It seems somewhat unintuitive also:

(Older) MK20 unit uses - 1J0907597B (which is what I bought (if anyone needs one, let me know, ? not sure they'll let me return it now.)
(Newer) MK60 unit uses - 1J0907597A (which I have now ordered, along with even more brake fluid ?)

So, waiting for the new sensor and the time to do this job AGAIN

Will keep you posted....
 
Stay positive, sure you will soon be able to laugh about it!
We all do things that if we had consulted a crystal ball we would have then done different?
Would a crows foot socket be beneficial?
Where have you bought the correct sensor from?
How frequent is your abs fault lamp occuring?
 
Thanks for the encouragement @Howey

I'm trying to jump straight to the laughing about it to keep my spirits up ?

I was considering those crows foot tools but I wasn't certain it would do it as one of the brake pipes runs right in front of the sensor, the bolt size is also very large and most of the sets I could find didn't go up that large.

The (new) new sensor I've ordered off ebay from eucarpartsltd the image of it is identical to the one I took out of the car with the same codes etc printed on it, so that's reassuring I think. Either way this time I will do a quick test by plugging it in to check my car recognises it before ripping it all out again!

With the old sensor, the three brake system related warning lights (traction control, brake pads, ABS) would come on usually after about 20mins or so of driving (most of the time but not always).
 
Fab! Keep on smiling!!

I wait with bated breath the outcome as mine comes on every so often (last time was when injector wiring needed adjustment)

GOOD LUCK!!
