Should I replace Airmatic seals as precaution

Hello All,

My 2000 S430 has 86K miles on it. I am planning to get the dealer to replace the front strut seals prophylactically (as a precaution).

What do the forum members think. Based on all I've read, it is only a matter of time before these seals go. On top of that, if the struts have minor leaks, they will overwork the air-pump that will also fail.

My thought is that if I have the seals replaced now (may also replace the air-pump relay), I should be in good shape.

Should I also be replacing the rear strut seals. Do these leak as often or is it just the front.

Thanks All.

Regards,
Vikram

Are the original owner of the car? If not, consult to see if the car has had them replaced. A 2000 going 86k miles without a single Airmatic failure is quite a feat.

Yes, 86K miles on original Airmatic!

I called the MBZ dealer and he went back to 22,000 miles and the seals have never been done! He said that the rear rarely go bad and that I should just get the fronts re-sealed for $600 (parts + labor).

I will drive it in tomorrow night. Hopefully the airmatic holds out until then... I will also buy another air-pump relay from the dealer while I am there and replace it myself. Why keep it in the glovebox!? I'll keep the old one in the glovebox as a spare.

Regards,
Vikram

It's a great idea to do it just in case. But It's a Rip OFF Don't go with that price!!! It's a NO NO I'm telling you.

All you need is 2 of these tops A2203202538. You can Order them through these guys

or

And only pay for labor. I mean It's a $200 job at most.

Best of luck!

I called a couple of independant euro repair shops and most of them have never really done the re-seal of the airmatic struts. Therefore, I have no choice but the local MBZ dealer who wants $600.

Does anyone know what the official estimate from MBZ is for resealing the front struts?

Vikram
