Poll: How many with 456M have replaced accumulators?

Jason, the accumulators and the light are not talking to each other.
If the light stays on it means one or more actuators are not working.

 

Taz, my suspension seems to have only one setting,hard. I have bought the accumulators,any special issue replacing. ?system need bleeding?

 

Andrew- Should not need bleeding. If you bought the BMW accumulators, you will need some washers because the holes are slightly larger.

 

After approx. 20 miles the suspension light extinguished. Now at about 200 miles still no suspension light.

The new accumulators are providing a much better ride.

Thans Taz,your the best.

 

Replaced mine with the BMW units. Car rides and handles great. Having had Citroens and Rolls/Bentleys with similar spheres they progressively lose gas
and need recharging or replacing every 15 years or their function is impaired.

 

I also replaced mine with BMW units at about 15 years mainly out of unknown history, from Classic Maserati experience 10 years on older type units New units have better rubber compounds

 

Also did mine earlier this year. Used the BMW ones, sourced online, manufactured by Febi Bilstein. Having spent many years in a past life working on Mercedes, I replaced a ton of them on the TD and TE wagons and the 560SELs.

If you were to cut one open, you'd see a diaphragm inside. On one side is nitrogen and on the other side is the pressurized oil (ATF in our case). When the diaphragm ruptures, the spheres lose their ability to act as a springing medium and then in turn hammer on the shocks causing, in some instances, the blowout as shown above. I had to put one used shock on a friend's '97 GTA because his split just like the one in the photo.

Case in point, if the arse end of your 456 isn't nice and 'floaty' it's time to change spheres ASAP!
