Mines Nov 2015.

Thx guys. I've got my eye on a reasonably price AP with low mileage. If I pull the trigger, I'll update once the port has been done

Looking at the code above the 06E we have
Dave "AM" (Sep 2014) - 020714
Tony "AP" (Sep 2015) - 010715
cadguy77 "AP" (Nov 2015) - 030915

So for my Mar 2015 S5 I am not surprised to see the date code 050215. However my p/n is 06E145601AT which I wasn't expecting.

Unlikely unless it was done without my knowledge. The first time I took off the engine cover was May 2017 and the code was the same. That was after MRC did the tune and MDK Technik did the service and no way either of them would have changed the supercharger without telling me. The only other opportunity was when Audi Basingstoke did the 1st service in 2016. Since it was the 1st service I was rather cautious and took before and after photos in the dealer's car park (do I have OCD or what?). The timestamps for those photos are 10:30 and 12:00 respectively, so they definitely didn't have time! But lastly the date code is 050215 corresponding to when it was manufactured. Surely I'd have a later date if it had been changed.

Is there anyway to find out what was changed between the AM->AP->AT revisions?

You'd have to ask Audi. I already knew that the letter revisions for VAG parts do not always relate to design revisions (i.e. it does not always indicated that changes or improvements were made). A bit more searching databases of different models for different markets yields the following. It is apparent that all models with the CREC engine have the same supercharger:

06E145691AM fitted to 28/01/2015
06E145691AT fitted between 28/01/2015 and 14/07/2015
06E145691AP fitted between 14/07/2015 and 28/05/2016
06E145691BD fitted between 28/05/2016 and 14/03/2017
06E145691BF fitted from 14/03/2017

It is not directly related to which clutch is fitted because

US A6
06E145105N fitted to 27/04/2015
06E145105R fitted from 27/04/2015

South Africa Q7
06E145105Q fitted to 14/04/2015
06E145105R fitted between 15/04/2015 and 09/02/2016
06E145105S fitted from 09/02/2016

My clutch is 06E145105N

@Dippy I did think it was a hit of a stretch that you SC would have been changed.
Yep Dippy won't let just anyone near his car! I don't think he has had the fuel rail recall done because it's not a proven fault, just an in case recall. I had mine done and Audi royally fooked mine and Cadguy had issues after his recall as its a big job removing the supercharger. Might be coincidence but both post issues were with coolant leaks. Audi rectified mine but said nothing wrong with it, just 'misting' from thermostat housing, yeah right, steam from under the bonnet, puddles on the undertray and an empty coolant tank says otherwise!! But it has been over a year now and absolutely no drop in coolant level.

Spotted this 06E145601BF, but one thing is bugging me: WTF is this?

Not seen one like that before :D

That's where the Helmholtz chamber is on the std intake pipe, so I'm guessing this is another version of the chamber. Reduces intake noise.

You'll be chucking this bit in the bin anyway as it wouldn't fit your larger TB.

On the B8 & B8.5 S4 it was possible to purchase ADS on its own (just the button).
However on the B8 & B8.5 S5 ADS could only be purchased with one or more of the 3 options (DS, DC & SD)
So on an S5 if it has the button it must* have at least 1 of the options, but you need to check which ones.
For the 2015 S5 the costs were:
ADS £220
DS (dynamic steering) £375
DC (damper control) £300
SD (sports diff) £620

Hi dippy, how if the above is true how would I find which option I had, doesn’t show anything in the “Car Menu”

I've just messaged and has a reply from Doug at MRC. He says they can lock the clutch module....

Wtf.
Sorry for bringing up an old thread, I'm a new member from the U.S and was searching all over to find more information about he magnetic clutch issues and figured that the ROW forums would have a lot more information on the CREC than the US forums considering you all have had the CREC for longer.

A lot of the threads that I've been reading say that there are only 2 or 3 instances of clutch failure and it's potentially slipping belt. I can say fairly definitively that it's not a slipping belt. There are now dozens of failed clutches here in the U.S to include mine. We've refitted new clutches with revised models, tried retrofitting the old snout, and now the latest work around is welding the clutch. Welding holds for much more power but even that has failed so now folks are welding a secondary weak point.

I guess this is a long-winded way of asking if there are any advancements towards a solution that the ROW guys have found that we have yet to figure out here? The above post says MRC found a way to lock the clutch module, has this been confirmed? Someone else mentioned in a different thread that they have engaged a clutch manufacturer to see if they can engineer a upgrade, any luck on that?

Thanks in advance and apologies for the long post.

I can confirm that an MRC tune locks the supercharger clutch permanently, even in D (stock, the car only locks the clutch in M and S). However, the supercharger clutch can even slip when the clutch is permanently locked/engaged, as has been the case in my car. Btw, my car is from mid-2015 also has the 06E145601AT supercharger but the clutch is slipping at a 3.0 pulley ratio (189mm crank pulley) at a reasonably low mileage (25k miles).

American tuner Integrated Engineering stated in another thread on Audizine that CREC supercharger clutch slip is imminent at a pulley ratio above 2.82, so I am thinking of moving down to a 175-177mm crank pulley to stay below that specified ratio. Integrated Engineering is also actively looking into a permanent fix of the supercharger clutch, so I asked what the status was and the answer was not hopeful:
“Unfortunately, at this time we haven't found a prominent solution, we are trying a wide range of fixes, and upgrades, but it's been difficult, to say the least, we've even tried welding the clutch and still it slipped, I have no ETA on when or even if we'll offer a real solution to the issue at this time.”
What is weird to me is that there are some owners who have experienced no clutch slip at or above ratios at which other owners have had experienced a slipping clutch. One user on German forum motor-talk is running a 3.13 ratio for over 2.5 years now with a CRE engine without clutch slip problems.
