The shocks are covered by the Wilbers 5 year warranty. The ESA? Don't know how BMW would handle that, though my aftermarket warranty should.Ok, now what happens when the ESA II control unit fails, since it is not sold as a separately ? Are there warranty issues as well? Are the shocks covered under warranty since the units are sold as one?
The typical failure looked for to determine if it is a covered item is the seal failure and leaking. Shocks are worn out well before the seal fails, in nearly every case.
