Go for the Saloon plus model, even more rare & maybe only ~100 of them in the world, as the vast majority of the C6's manufactured were Avants. The 500 plus models were made up of saloons and avants, so the Saloon plus model is even more exclusive...

Maybe check this one... http://wiki.ross-tech.com/wiki/index.php/01521

About the MMI unit if you give me a VIN I can tell you which one you have on your car.

Thanks.

VIN number is WUAZZZ4F9BN999419

Can anyone confirm the MMI control module part number for the 2010 car?

I can see from ebay a normal A6 C6 part number is 4E0035729, but not sure if the RS6 has the name part number or not?

Thanks

Initialise is the reset option, it causes the TPMS to recognise the sensors (and register new ones) and their locations on the car. Store pressures logs base pressures for each sensor - when (if) a sensor pressure has dropped by a certain percentage (10%? Maybe, I don't know the figure) the TPM uni...

Silly question, have you selected "Reset" in the TPMS menu on the MMi after you replaced the sensor? Hi Ian, I dont have a "reset" option to select. When i go into the TPMS in MMI, i have 3 options, - display tyre pressures - store tyre pressures - Initialise after wheel change I've tried to Initia...

Hi All, I've got a TPMS issue that hopefully some of you guys can maybe help me with. The TPMS light came on & the error code pointed to the front left, so i got the sensor replaced. The issue seemed to have been fixed with all tyre pressures being displayed on the MMI screen, but 15mins of driving,...

I drive about 4hrs to 4.5hrs non-stop every 6-8 weeks visiting family/friends back in my home town, and I occasionally drive around 3.5hrs non-stop to see bands in Wolverhampton with another 3.5hrs drive back a few hours later and I've not had any issues with my ECU's so far. However, just because ...

The cars running 750whp

From that I take it that there's non-OE maps on the ecus?

Correct, i'm running stage 3, which maybe contributing to the issues, so it would be good to know if anyone else has experienced something similar. The fault appears as a check sum error code on both ecu's.

I think I've made this very confusing for which I'm sorry. From the numbers you've shown on your ECU I think this is actually a set of "hardware" AND "software" part numbers i.e. Pt No 4F5910552B is the for the Hardware (the physical ECU) AND the Software combined, whilst Pt No 4F1907552A is just f...

Having had a deeper look, its definitely only the 4F1910552D (or 4F1910552DX for an exchanged ECU) thats for the RS6, all the other letters are for other models like the S6/A6 etc - the physical device has the same part number whether its an ECU for an A6, S6 or RS6 etc but the Letter defines what ...

One or both ecus Think it will just be 1 ECU. Still trying to get to the root cause of the issue, but the issue looks to be with only 1 ECU. Cheers Roy Hmmm...update seems to be that the check sum errors are affecting both ECU's. So looks like i may be looking for a pair. Does anyone know whether t...

Thanks for the info.

Would I be correct in saying the 5.2l S6 ECU would be suitable for our RS6? The part no 4F1910552 seems to be common accross both cars.

Thanks
Roy

Hi everyone, Unfortunately i've had an ecu issue over the weekend. The workshop still has fault finding to do, given i've been on the back of a tow truck for 350km today, but lookimg like i might need a new ECU? Does anyone have one or know the best place to look for one that can then just be re-pro...

Thanks for the info & maybe it now makes sense.... My car is my daily & most days driving in/around town, therefore not doing heavy braking, which i guess adds up to the point being that high spots can develop with these discs. I'll try & re-bed the discs again & see how that goes. If the vibration ...
