Made some progress on the TPMS sensors. I made a concerted effort with the vagcom to figure out what was going on. I was getting a reading from a couple of sensors but not the new one, or so I thought. In the measuring blocks you can go through the positions and see what the sensors are reading (if ...

First thing to check is the ATF level and make sure the strainer isn’t blocked or cracked. Then I guess it could be a major mechanical failure like torque converter or ATF pump. The latter can easily be damaged if care isn’t taken when remounting the box.

Ill have a look on mine later to see if I can find an output test.

Yeah, I've got 3 spares ones now.

The cable length was fine though.

The RS6 has the rectangular connector with the rounded end, not the circular connector. Maybe check your plug again?

I replaced the failed HUF sensor with one of these, but I can't get it to communicate at all. It's pissing me off. Last time I replaced all the OE sensors with HUF ones and I didn't have to do anything to get them to work. So either these sensors are junk or I need a TPMS tool to "wake them up" so t...

If you can do it, then it will be with the output tests on the ECU module with VCDS. I can't remember off-hand whether it's one of the outputs that's activated. I can check later, possibly.

Good info. I'll be interested to see where the TCU is measuring the voltage, too.

As for the water ingress, the Audi engineers should hang their heads in shame at the pitiful lip-service to weatherproofing.

It is a lifetime fluid. It’s just that Audi’s definition of lifetime is “old enough to be outside of warranty”.

But Audi procedures don’t even call for changing the water pump when doing the timing belt.

It's such a crap system. I saw on a different A6 platform car of the same era that it has a more secure cover on the pollen filter. Who knows why they didn't use the same on the RS6. It's a terrible design and can easily let water in from the windscreen run-off directly into the middle of the pollen...

What makes you think this fan is internal to the climatronic unit? I'm not convinced it is.

/Looks like it probably is. I can't find a separate fan in the parts catalogue.

Can't you just swap the fan out?

It was the T17m connector I was trying to identify , do I just follow the TCU lom to under the dash? Yeah, I think it goes up the A-pillar, so remove that bit of trim and you should see a bunch of connectors. It's a blue one. I have seen the two black wires going to pins 55+54 , they are joined tog...

No, I don't think so. There aren't any variants in the parts catalogue, just lhd and rhd. The S6 had it, as did lots of other C5 platform cars. Maybe that's where the confusion is coming from.
