I'm trying to find which suspension parts (coils, shocks and anti-roll bars) are shared between different models/options and I would like to identify the following suspension option code:
1BA - Standard suspension/shock absorption 1BD - Suspension/shock absorption for special sports design 1BE - Sports suspension/shock absorption 1BL - Suspension/shock absorption (ADS) 1BM - Standard suspension/shock absorption 2MV - ??? (ADS)
Pardon if I am missing your point, but I understood that for the A5 there are just 3 suspension options.
1BA - Standard suspension/shock absorption -> which is the default 'Dynamic suspension' (non adaptive)
1BE - Sports suspension/shock absorption -> this is the 23mm lowered 'Sports suspension' (non adaptive) and also part of the S-line and wheels packages
1BL - Suspension/shock absorption (closed-loop) -> this is the only avail 'Comfort adaptive suspension' which is 10mm lowered
Played around with various configurations at Audi.de and those were it. This is for the A5, can't speak for the S5.
I did this table that shows how suspension parts are share between the different suspension options.
According to part numbers,
- S5 Sport suspensions use different shocks and a (smaller?) rear anti-roll bar than A5 Sport suspension.
- S5 Adaptive suspension is the same as A5 Adaptive suspension except for front and rear anti-roll bars.
- S5 Sport and Adaptive suspensions use different shocks/coils but the same anti-roll bars.
- A5 Adaptive suspension uses smaller anti-roll bars (at least at the rear) than the A5 Standard/Sport suspensions!
Also according to part numbers, all suspensions seem to use the same rear coils (for any particular weight range)!!! Since there are different ride heights, something must be wrong...
It it also strange that the S5 uses smaller anti-roll bar at the rear than the A5 Standard and Sport suspensions.
1BA - Comfort Dynamic suspension
1BE - Sport suspension
1BL - Adaptive comfort suspension with damping control
And the S5 has:
1BD - S Sport suspension
2MV - Adaptive S Sport suspension with damping control
What is 1BM - Standard suspension/shock absorption?
No, 1BA is standard suspension, not Comfort. There is a comfort (raised) fixed suspension made for the A4 with a different code, not available in NA region, not available on A5/S5.
1BM is a generic Audi code for standard suspension, but they use 1BA for B9, have never seen 1BM used for either B8 or B9.
You are aware that PR codes are option description codes, and do not directly link back to part numbers? IOW, the A4/S4 by example use the same PR codes, but the parts may be different, and usually are. By example, a 1BE in A4 uses different springs than 1BE in A5.

I used description given by Audi UK....But Standard suspension is probably more appropriated.
There is definitely a 6th setup for the 2018 A5/S5 Coupe/SB. It's similar to 1BA except for the front coils/bar and rear upper coil spring support that are different.

Can't see any configuration that invokes 1BM rather than 1BA. In fact, I can't see any MLB Evo vehicle using 1BM.
As I mentioned earlier, they do have a fixed comfort suspension, PR code is 1BR, but am fairly sure this is only available on the A4.
As you said in your other post, some data seems suspect. An S5 with 2MV feels distinctly stiffer than an A5 on 1BL, particularly in Dynamic mode. Of course, with the CDC dampers, I guess it is possible that the chassis ECU programming is controlling the valving, and the damper units themselves are the same.
My understanding is that, unlike with the A4 range, all A5/S5 models have the same ride height - broadly equivalent to the S4.
With the sway bars, it is possible that they are not all identical construction / material, so that diameter is not solely determining torsional stiffness?

Interesting work - keep us posted!
I used the part numbers to determine that sway bars were the same. Not the diameter.
This is super helpful when making model/options decisions! Thanks so much Yosh!

i have i little question. it is difference between fwd vs quattro. i have quattro (aero rims in picture) and my car is lower than other car without quattro. My code is 1ba standard suspension.

What is your suspension code?
