(I wanted to start from replacing only the connector to new and then replacing the full switch if it does't help?)
I think the connector on the fly lead is easy to get at, several people have opened it up and checked/cleaned the contacts with mixed results. The problem I and others have had is wear/corrosion on the moving parts INSIDE the switch.

Sergei, you are not known for doing half-hearted jobs Given the construction of the switch (see my thread with photos) it doesnt give the impression that a squirt of electrical cleaner or any other form of repair would do the business. With mine, one (at least) of the contactors was damaged. It MIGHT have been possible to have built it up with solder but i wouldnt have given tuppence for it lasting. The F125 switch is £153 (IIRC) + VAT so it should give you peace of mind for another 100k

Agreed. Cleaning the inside of mine has solved the problem for now, but its not a long term solution as the contacts are clearly wearing away. I was curious so it was worth a try but I have no idea how long it will last. It may be another 100K, but it may be a few weeks. Certainly if you have to pay a garage 4-5 hours to do the job there is no point whatsoever in skimping on £180 for a new switch.

So as I said earlier:

I'm seriously convinced that all those comments about cleaning ABS sensors etc. are just coincidental and that the real cause of the 01119 error is a worn F125 switch.

I did wonder, but forgot to ask yesterday. Just assumed as you turned up in the S8 to tow another away that it was behaving itself.

Interestingly, since having 'mended' my F125, mine is now doing this most of the time. The first 50% of the throttle does very little, but prod it a bit further and it takes off like a rocket. It happens mostly in 1st which is very annoying, but also randomly in other gears. If I'm in town pootling around at 30 and slow down for something it'll take a hefty prod to make it move, at which point it changes down to 2nd and goes a bit nuts. Its much better behaved in tiptronic, to the point I had to tow the FE home entirely in tip otherwise it would barely move. No codes either.

Time for a new switch methinks...

Check your brake pedal switch too. Had a similar problem with mine a few years ago, turned out to be iffy brake pedal switch contacts. I noticed the fault would tend to occur more after firm braking and tapping/wiggling the brake pedal before setting off again seemed to alleviate it.
