Hi all,

I bought a 2003 CLK430 last month with 79600 miles. Now it has 80500 miles and I stopped by at the MB dealer today as it was rattling where the cats are and they said that the warranty is expired and gave me a quote of $800 to replace one cat on passanger side. (I know I should have checked it when I got it but I did not know about the warranty and I just ignored the rattle)
I read lot of threads but could not get more information on a 03 clk430 model. I live in Oklahoma and I dont think they test the cats??
Please help......Let me know if you have done anything cheaper that fixed the problem and you did not loose any power or/and check engine light came on???
Thank you.

I am in oklahoma too ...what part r u in ? Anyway, are u talking about your second cats or the primary ? or maybe u have only primary no second ? I still have mine 2nd cats from mine CLK500 if it fits you can have it for cheap.

03 430? Isn't that a W208?

I live in Broken Arrow and I think I have only 2 cats. I am not sure if yours will fit mine but I will do some research and get back to you. (If they fits and I get them cheap, I will drive wherever you are ) Thanks.

I looked closely before posting here as this was my first post.
It says W208 upto 2002 and If I look for W209, clk430 is not included

What have u done to your car already ? or is it stock ? And you should post this in W208 section ...this is W209. Do you have any pics under your car showing your cats ? thats way i can tell ...

Most of use here have removed our 2nd cats. If that is what's giving you the problem, you could always go to an exhaust shop and put straight pipes in their place.

sach4u1

Yes it is. I have posted the same thread on W208 section. Thanks guys.

I will upload the picture once I get home. Where do you live btw?

OKC. How long it takes to get here in the city ?

It takes couple hours but I looked and there are two cats. But thanks for the help.

sach4u1

Does anyone know the part number for the cats?

dynomite05

Primary? secondary?

sach4u1

Both?? I am not sure which one is bad. I dont know the difference.
I went to the MB dealership yesterday, the service advisor said that the passenger side cat is bad and gave me quote of $800 to replace the passenger side cat.
I also have local mechanic looked at it and said the cat is bad. He is very brilliant and going to give me a quote on monday.
I am also taking the car to the local muffler shop on monday ans see what he has to say.
Thanks.

It's probably a primary, you might not even have secondary.

Major emission control parts are covered under 8 year/80k warranty as mandated by the Feds. You may want to look into this:

No guarantees, but worth a shot.

i had the same problem on my s class. if i remember correctly its the shields on the converter that become rusted or the screwes that hold it down become lose. it wasnt very expensive to ix..is the sound like a chain ratteling?kinda?

sach4u1

I went to a muffler shop this morning. He explained me about the primary and secondary cats. The secondary were the ones rattling. He removed those and welded new pipes. He said there is no sensor at the secondary cats so the check engine light wont be a problem. $100 and its fixed.

sach4u1

Thank you all for your replies.

Good stuff, all fixed up for 100 bux and a bit better exhaust note to boot. You my friend are having a good day!

dynomite05

Good to hear it's taken care of, and you didn't pay an arm and a leg.

M-bENZ

yep there is no sensors on the secondary cats .
