After much consideration and a very empty o/s/f shocker i finally decided to purchace and fit a new dealer supplied edc shocker. The slightly upsetting thing is there are 3 more on the car:1zhelp: ok at the moment but a time bomb i'm sure... The final kick in the plums was the (EDC SYSTEM INACTIVE) came on on the way home! I'll plug it in tomorrow and it better have been joking... Drives much better now though, time will tell.

Does anyone else have this, do i don't i dilema at the moment?

Good. Now you have one new and one used front shocks. Let's hope they have the same damping characteristics, or you're in for some funny handling.
Then you can start saving for the next 3, which wil not get cheaper with time...

My own car.
2 pairs of damper on front ( second pair still on vehicle)
1 pair on rear ( still on vehicle)
Thats after 100k miles in my care out of 183k miles.

Done some for others & customers.
Not a fun job.

Interesting fault code for a failed damper if only leaking oil.
Something does not add up.

I would readily reaplace individual dampers.
Damping characteristics controlled by measured input signals from sensors
around vehicle.

However, I would recommend changing springs, top mounts ,bump rubbers,
bellows etc across the axle pair.
The other damper might last another 20k miles.....might not !

Thats good advice, i've replaced all 4 bumpstops dust covers and both rear top mounts already. Farrell, i'll plug it in and see what the fault says and let you know, cheers

Exactly, the control unit for the EDCIII is able to individually adjust pressure and duration (=flow) per shock-absorber and thus (within margins) compensate for aging of individual shocks. But this only applies for EDC equiped cars and thus not for the HD91 cars without! For those, George his fears are justified.

However, wear between shocks depends heavily on usage and the balance between right hand and left hand corners. This might result in one shock to collapse sooner then the other. How many life still is left in the other is nothing more then guessing. It might last a year (or two), but can also collapse within a month.
