Hello all- I'm pretty sure I've got a nasty little Siemens relay in slot "O", so I'd like to replace it with a Hella. Any ideas on where to get it? AZ Autohaus has this:

...but I'm not sure if these are the ones, since they say "multipurpose".

Any ideas? Thanks- I want to get that bad boy out of there!

..so I guess the question would be... does it need the 4 or 5 prong relay?

hi I have a 00 s500 , if i leave the car sitting for a few days its sitting on all four tires. when I start it up up it raises back up is this some type of electric problem or air leak, etc. can someone help me please.

socalsounds

Possible bad seals or leaking line connections. Sounds like the pump is working, so... Pay to have it diagnosed- it's worth it.

Back to my thread.

Anyone know whether its the 4 or 5 blade relay? Thanks

Post 18 at https://mbworld.org/forums/s-class-w...ic-failed.html has a photo with the Hella part number. Post #10 at https://mbworld.org/forums/s-class-w...ic-issues.html provides more information and part numbers. I believe any of the ones mentioned in those posts will work.

You can pull the relay you have now to see if it is 4 or 5 prong. If it is a 4 prong relay and there are 5 slots in the fuse panel, then it is likely a 5 prong would also work - but one prong isn't wired up in the panel. Let us know what you find.

Thanks for the reply- I'll get back with an update on the part number. It sounds like AZAutohaus has a pretty great price- but I need to cross check their internal part number against the Hella (7219) part number.

Back to the ham... (don't ask me how I got saddled with it , but it'll be tasty in about 5 more hours...)

Happy holidays!

OK, Guys, in the above link, at leat for my 2001, it is the top (1319) relay. At $7 bones and change, that beats the dealer (for the same exact part) by $30! I ordered 3.

Have a great Christmas and New Years, guys!

was there any problem with the siemens relay or are you just upgrading to the Hella to prevent a future problem??

socalsounds

Nope- but I spoke with my master tech, who advised me that the Siemens relays are very poorly built- if this relay bypasses on you, the pump will be fried. The Hellas pretty much don't fail, so it's peace of mind....

Also, several other critical systems use the 4 blade relay, and it's advisable to upgrade them to the more stout Hella as well, according to my tech...

Hey Chris:

I don't have any issues as of yet with my airmatic (2001 S430) however I want to be safe from a precautionary standpoint. I know I have Siemans relay and would like to replace with a Hella Did yours work??? ...Could you you let me which one to pull out off the passenger side fuse box ... I see 3 of them in there. Also is there any other steps and I should be kooking out for to prevent an airmatic failure.

I also noticed a couple of minute hairline cracks forming around the black surface on the top of the strut assemblies in the front. Is this something to worry about??

Thanks.
