TPMS MHz

[anditsoundslikebells]

I'm buying some new TPMS and want to be sure I buy the correct ones. I've found conflicting info.

In thread:
"Different part numbers for C5 and C7. C5 are 4D0907275D and uses 315Mhz, C7 are 7PP907275F (433mhz)"
search.php?keywords=315MHz

on ebay:
"Audi RS6 2000 - 2008 TPMS Huf RDE001 Direct Fit 433MHz (NEW)"
https://www.ebay.co.uk/itm/Audi-RS6-200 ... 2991624010

I checked but couldn't find them here:
https://audi.7zap.com/en/rdw/audi+rs6+r ... 601080/#15

From the two options, I guess it's 315MHz?

Can someone share a link to a Huf TPMS that is correct for my '03?
(somewhere I've read another thread in the C5-sub but I can't find it)

Hurrah - one I can answer...

I took the tyres off my alloys on Saturday and the Audi p/n is 4D0 907 275 433mhz. I think they are now HUF RDE001.

All this is well and good, but I've just noticed in your sig, you have a TVR ! Any pics to share ?

Easiest to link to the advert.

I'm also interested as I'm having my wheels refurbished and I don't know how good the existing sensors are. Searching Autodoc for the 4D0907275 part number gives me Ridex 433mhz sensors at £ 28 each rising to £ 82.61 for HUF ones. Has anyone used the cheap type with success? Seems a big difference for a comparatively crude system that can be turned off easily.

I bought some Huf RDE001.

The auto doc ones sound like very good value. I’d try those if you’re sure they’re compatible.

[norwichphoto]

Well I've double checked and they run on the same frequency and all the documentation says they're compatible with the OEM number, so I've ordered a set. Total including valve stems and VAT was £ 131.92 for 4, so £ 32.98 per corner. I don't want to run the car until cambelt is done, so waiting for my turn to borrow the tools, but will report back soon.

[Shoppinit]

Bargain. Let us know. I might get a set.

Has anybody tried these? https://tpmszone.co.uk/product/tx-s001- ... ms-sensor/

The Schrader sensors on autodoc also look very good value, and I've at least heard of Schrader before: https://www.autodoc.co.uk/schrader/14528209

Did you try these out?

[norwichphoto]

Yes. They have proven to work fine. Occassionally get a warning but its generally when its been a really cold day compared and the pressure has just dipped under whatever the tolerance is. I normally run 3 bar pressure.

I got mine from UK Parts Direct, their reference HHS-Audi-RS6-1. https://www.ukpartsdirect.com/audi-rs6- ... o-fit.html

I had new tyres fitted November 2023 - but I think the sensors were reused with new valves / seats.

Was also looking on Autodoc for TPMs, glad that the cheaper ones seem to be working fine, was going to order the Huf ones, but if your ones are working fine dont see the reason for the extra expense, have spent enough on it this year....

Thanks. Not come across that brand before.
