Sorry for my English, I'm not a native speaker.

After installing Bilshtein b16 pss9 (without damptronic) a problem with ABS has occurred. My car is 997 Carrera S, manual transmission, 2011, and it had a PASM from factory. I ordered B16 without Damptronic because I have an experience of adjusting this suspension on my previous cars, and I did not want electronic suspension. After installing suspension, even at low speeds, when I press a brake pedal (softly) ABS starts working. First we thought the problem was with cross balancing, but after we adjusted cross weight, the problem remained. When we disconnected PASM, sport mode stopped working. Our next guess was the electronics disfunction. I bought PASM cancelation kit from KW suspensions. After installing this cancellation kit the sport mode started working, but the problem was still there. I have no clue what to do. My local dealer is very stupid, he can only change oil and brake pads. So I can not get any help from them. They checked ABS sensors, and did not find any problems.
What are your suggestions? Can you tell me how to align the suspension rate? What height of front and rear axle, cross weight, weight distribution (front/rear) are needed? And how many clicks do you make to adjust front/rear axle? I made 3 clicks from stiff setting at front, and 5 clicks at rear axle. Thank you in advance.

My cross weight, after installing B16
FL 284.5kg FR 271.5kg
RL 454.5kg RR 450 kg

Front 38.07%
Rear 61.93%

Cross 49.73%

 

have you checked to see if there are there any fault codes? i bet your problem is more with PSM. maybe it's confused because of the PASM change.

or is your ride height very different from stock? are you using different size wheels from stock?

 

Fault codes appear when we disconected PASM, but there is two solutions of this problem. 1) You can disconect PASM unit (under glovebox) and disable it by PIVIS
2) You can connect "PASM cencelation kit" and computer of your car will see PASM and no fault codes will appear.

I agree, PASM, ABS and PSM work together. My car is from USA and you can not disable PSM completely. When we disconected PSM fuse, ABS and PASM stoped working too.

Yes, we changed ride height, but when we searched solution of problem with ABS, we tried diffrent heights. Lower then stock, higher ect.


I`m using stock wheels.

One more clue. In mounting instruction of the suspension say - After installing of the suspension system Check and reset load-dependent brake compensator and ABS system according to manufacturer`s specifications.
How to do it and what is load-dependent brake compensator? I`ve asked my dealer about it, but they don`t know.

 

i have no idea what a load dependent brake comp is. i'm surprised the dealer couldnt fig it out. i put PSS10 on my '06S and have had no problems with ABS/PSM. sorry and good luck.

 

Thanks!!!
