One of the major issues as the Audipages "how-to" points out and my garage found is getting clearance from the exhaust to get access to some of the bolts. It requires some brute force.:)

That is optimistic in the extreme! You can't get the mount out with weight on it, so you have to jack up the back of the transmission to remove it. I found that out when I forgot to re-attach the shifter cable after putting the engine back in the first time :o

The bolt behind the downpipe is going to require a special took I think. Its actually not that painful to move that downpipe on mine as I have the SAI removed so I can get to the top manifold bolt, but on a stock car you'd really want to do it without moving the downpipe so you need a super-short T27 I think.

As the Titanic is still on the lift (don't ask) I can't check for a week or two so I'm just going to have to live with it on mine for a bit :(

I did wonder that myself, but then I didn't write this stuff. :ROFL:

I've printed off the Audipages guide to give to the garage on Friday, along with Bentley.

I did that as well but you may need to point out the fact that its written for a LHD - the mechanic who actually did some of the work initially disregarded it as it "was wrong" as it states the switch was on the "drivers side of the car". :rolleyes: he was quickly put right by the senior guy.

The Audipages guide certainly makes it clear in step 6 that the transmission needs supporting with a jack.
I attach a pdf precis of the guide which I made which cuts it down to 8 pages and easier for printing. All steps are there, its just resized the pictures and cut out some introductory waffle. I also changed it to reflect the 10pin rectangular plug on the later cars although the picture still shows the 8 pin round one.

Thanks David, I had already annotated my printout accordingly, though I think they do actually know where it is. ;)

Just a little footnote.

Having set up Bentley inside XP inside Oracle Virtualbox I remembered that long ago some kind person here (sorry but I've forgotten who!) gave me a copy of Elsawin (v3.60?) running inside an older version of Virtualbox.
To my shame I'd never really delved into it and with PC changes and upgrading to W10 never reloaded it. :o

So I found it, copied the virtual disk file (.vdi) across and quickly set up a second virtual PC to run it. Works a treat. +++
(Just need to put it on the laptop now, alongside VCDS and Bentley, and learn how to use it)

The point of this is (finally) that I then looked up, in Elsawin, the procedure for replacing the F125 switch.
And sadly (but not surprisingly) it's exactly the same, and just as brief, as in Bentley. :(

All done, just off to collect it (and the old F125) a bit later.
They did say it wasn't particularly difficult as the exhaust came off OK (they had it apart not long ago to replace the N/S catalyst so I hoped for that) and the mounts were fine too, no difficult bolts.
I asked if they'd tested it in all gears and they said they'd been through the local back roads and then along the local "autobahn" (about 3 miles away) and it was all good. :cool:

I'm going to have to do mine pretty soon. It goes in to limp immediately if I select D from cold, so I have to drive it about in S for ten minutes until it warms up, then D works fine for the rest of the day.

It'd be nice to re-engineer an optical version of this so it doesn't wear out, since eventually these are going to become NLA, but the contacts are set up so that the ECU knows in which direction the shifter is moving, so replicating that would be very complicated. Maybe that's a challenge for a few year's time...

Good to hear. +++
Just as a matter of interest, how many hours did they book to the F125 job?

5 hours labour, which is what they predicted if all went well. Not sure they did use all that, but then I don't know how many people it needed for some tasks.
I dropped it of at 8:30am and they were on the phone at 2pm saying it was done.

I presume to open the switch you drill out those 7 little rivet fixings?

Been for a local drive, all seems well so far and absolutely no hint of hesitation, but only time will tell. Fingers crossed. ;)
Note to self; Go and clear the old error codes - NOW!
