Poll: How many with 456M have replaced accumulators?

That is not a function of either the actuators or the accumulators. It is a function of the leveling valve.

Why don't you let them diagnose it?

Don't ever tell the shoemaker how to make shoes.

 

Who ever reassembled them hasn't set the platforms at the correct height.
They have adjustable platforms and the work shop manual has the dimension

I replaced mine when I rebuilt all my shocks and rebuilt my actuators only because of all the hype about the issue, but truthfully mine were fine. I just figured if they were fine, they may not stay that way, so better do it while we're on the subject

 

Mine are shot. Replacing soon.

 

I've had loads of other problems and my suspension failure light is on, but the shock actuators work fine; Craig at The Jag Shop said there's apparently a communication problem in the computer somewhere. I need to take it to the dealer to diagnose why the computer doesn't understand that they're working fine. Any ideas?

 

I replaced mine 4 years ago. My suspension failure light has been on ever since.

 

Just changed mine, now suspension light on. Have you been able to extinguish the suspension light?

Thanks
Dennis

 

The suspension light is from my understanding a result of actuators on top of the shocks not a problem with the shocks. It may be the actuators aren't fitted correctly or the plastic internal gear may have failed.
Have a look at Captain Z site as he covers Vets Ferrari and Maserati actuators

Graeme- Other things besides the actuators can illuminate that lamp.

 

Terry absolutely, I was endeavouring to explore options based on others experience.

 

Replaced mine in 2015 (1995 456GT).

 

When you say replaced, The actuators or just the gear set?

 

Replaced my rear accumulators last fall.

 

I replaced my accumulators. The suspension light was not on before or afterward. However, you could tell something was wrong with the rear suspension when the accumulators were bad.

I have never replaced the shock actuators.

 

I had mine replaced with BMW ones due age and lack of use. I did notice a more floaty ride.
Selecting Sport ties it down. I also need new seals in the rear shocks for the classic reason.

 

Mine replaced with OEM accumulators by prior owner a couple years ago (@ ~33K miles)

 

Replaced with BMW accumulators 2 years ago. Removed a lot of the ride harshness we experienced.No issue with light.

 

Apparently, you can add mine to the list. 96gt, BMW accumulators just fitted

 

I replaced my accumulators a month or so ago with the BMW units identified on other threads here in FChat regarding this subject. Mine were bad causing one of the rear shocks to explode (Hydrolock) and the other to swell the shock case making them both unusable for rebuild. Thankfully, I located a pair of good donor shocks that Rob at Delta Vee did an excellent job rebuilding. The actuators were reinstalled after a thorough inspection and as others have said here on this thread, there was no suspension light on before or after. The car drives and handles noticeably better.
