Just started a couple of days ago. when standing at the hatch on my 99 e320 4 matic wagon with it idling I can hear a rattle coming from the exhast system. It doesn't seem s though it is a loose exhaust bracket but I could be wrong. when I push on the exaust it doesnt seem to do anything and it is not a continious rattle. Could this be a cat. coverter? Thanks in advance. :bowdown:

btw it has just turned 75kmiles

Yes it might be a catalytic converter. Does it sound like there are marbles ratting around against metal in that area? There is a 8 year 80,000 factory warranty on those so you might be just in time.

Is that honored at any dealership? I am the 2nd owner and did not purchase it from a mb dealer. I have an idy mech. and have never had it to the local dealer here.

Yes, any dealer should honor that and you don't have to be the original owner. You obviously beat the 80,000 miles; now check to see how many years your car has been in service (start from original date of purchase). If it's less than 8 years you're in luck!

He's

very close to running out of time if it already not past time.Call the dealer give them your vin or go in and ask.It is not money out of their pocket so since they make money from the parent company some members have squeeked by with over 8 years and over 80 k miles,worth a try and no harm asking.
If past you can splice in universal cats that do the job from racepages.com and others.

april 9th 1999 the vehicle was registered as a personal vehicle in Illinois. sounds like I will be reading the post on changing converters soon. But I will probably wait untill it fails completely. Any harm in doing that?

Like Ohlord said, ask the dealer anyway even though you are over the years "limit". If you were over on the mileage too, that might be different. I think you can only harm other parts of your engine if it is completely plugged up. I think you are only causing a little more pollution by driving it in that condition, but wait for Ohlord's answer to that.

Thanks for the help guys I really do appreciate it. will the temp readings used in the cat diy sticky work if the cat is not plugged yet?

 

[Musikmann]

Sorry, I just looked and didn't see that.

Is

that the diy I gave a member a few months ago?Read pre cat and post cat temps after the car is brought to temp and measure with a non contact infrared.
Or you can get under it safely supported or on a lift and give it the thump test(car cold)with the palm of your hand.
try to act naive at the dealer see what they come up with.
Eventually if it is a cat and not a loose bracket,it will cause misfires and poor running and other codes.

Thats the one. I was wondering if that will work if it is not yet blocked. In that one he was checking temp to verify which cat was blocked. I havent bought a infared temp gauge yet. I also noticed that the car usually makes the noice when it is still cold and not yet up to operating temp. I am going to try to get her up on wheel stands tonight and get a good look at her rear end and see if I can see anything. Oh and if I have time I might work on the car too. YOU GUYS ARE THE BEST:thumbsup::thumbsup::thumbsup::bowdown: THANKS AGAIN FOR EVERYTHING AND I WILL KEEP YOU UPDATED.
