EDC shocks
Hi Rick,
If you still haven't resolved your EDC issue, your best bet is to have a mechanic check out your setup.
EDCs do fade over time or eventually fail and require replacement.
When working properly, you should feel a difference between the "S"port and "K"omfort modes, especially when cornering or going over bumps.
It is also possible, as suggested, that your EDCs were replaced with a non-factory, non-adjustable setup. Many owners went this route when their EDCs failed because they are very expensive to replace. I believe you are looking at around $1,000.00 USD per corner in parts alone -- a little more or less depending on your parts source.
If you can afford the replacements, I have the EDC in my '92 750il, and I think it is very nice to be able adjust the shocks to suit your immediate driving preference. I was fortunate because though my 750 had 130k miles on it when I bought it, the EDC inserts had already been replaced, so I shouldn't have to deal with the costly repair anytime soon, with some luck.
Otherwise, a popular replacement is an H&R Spring/Bilstien insert combination, mentioned above in this thread.
Hope this helps, and best of luck to you.
