I've had the dreaded PADM fault pop up and have been waiting 3 weeks for the part via a Porsche specialist to turn up, however it is STILL on back order. Is anyone else experiencing an issue getting hold of this part via a OPC or Specialist? I've got a road trip planned in a couple of weeks and really want it sorted before I go despite knowing that the car can be driven with this fault present.

I wonder if the mounts are different for a GT4 vs a 991.1 C2S...?

Why not standard mounts and code out the fault?

Yeah could do, but I'd rather keep it OEM despite knowing the gains are VERY marginal

Do the replacements last any longer? Have they been modified?

I haven't heard about any replacements breaking. Maybe they have upgraded the part.

Yes modified parts were introduced about 18 months ago - I had them fitted to my 718 Spyder

You can't code it out, that's the problem and people have tried for years with no success. Given the way they work an electrical signal energises the magnetic particles in the fluid. They receive varying signals depending on how much the mount needs to firm up based on driving style. Because it's not constant you can't isolate it and it will throw a fault.

The small PCB on top of the mount fails, usually water ingress. There is somebody in China who has replicated the PCB and new casing but it's not widely available yet.



Perhaps I was lucky in 91k miles in my 2016 718 Boxster it was still on the original PADM with no record warranty or otherwise of them every being changed.

It's perhaps no surprise that these mounts are made by that trusted UK bastion of engineering excellence - Lucas rolleyes

Wow, these are such a massive PITA!

A chap uses the DSC controller to avoid codes:-

"Using the DSC controller will avoid any error codes with the engine mounts and set to 1mA output current across the range means it's not really doing anything other than prevent errors."

HTH,

Thought they were made by Delphi (spinout from GM). Lucas Diesel is part of this group .. but don't do engine mounts.

You could be right but the point is this part has been known to be an issue for 10+ yrs and so far despite several 'revisions' of the mount it's still failing at varying points in time. Time to go back to the drawing board. Innovative idea poorly executed.

Completely agree. I read on their 8th revision.

Just called my OPC and 991.1 mounts are on back order so it is different for each model. Been waiting for a month now which is surprising because you would've thought they'd have had a big stock if they're that unreliable as a part
