advice needed on cat converters
 

i have been chasing down a ses light for weeks and finally gave up and went to the dealer. in have a clogged cat in bank 1. the cats are $750.00 a piece plus insatllation. they told me you mime as well replace them both because to take out the one that needs replacing you have to take them both out. i am a diy'er and would like to attempt this job but not to sure on the way to tackle it. the job books out at the dealer at 6hrs which means it will probbaly take me a full day. my question is, is this a diy job? any idea where to by oem cats for less money? or should i just give it to the dealer for $2000.00? :dunno:

Someone else can correct me but it seems that cats have by law a 100,000 mile warranty correct? http://www.epa.gov/otaq/consumer/warr95fs.txt However If your X is out of warranty what's to prevent you from ordering the parts from BMW and having the local muffler shop do the job. I just had a similar job done on my MBZ and my previously owned 7 series. I found a muffler shop that came highly recommended and everything went great. Just get some estimates first then proceed.

my mileage is 81500. :mad: do you think that maybe they would cover half or part? that would be great. what about oem parts? any place that would carry them cheaper than BMW?

bring it to a muffler shop.. It will be quite a bit cheaper. It's not a DIY since there will be some cutting and welding involved. But definitely explore what Barry said in the other post.

MixMan:
My '01 MY Warranty book states on page 35, that Catalytic Converter (s) are covered under Fed law for 8 years or 80K miles, whichever comes first.

You didn't state your mileage, but if it's under 80K, I'd lean on them.

Thanks bro. I knew there was something like that. Is federal or state?

QwkAG: This is like a term paper project, :p

The fine print will make your hair hurt:

For US & Puerto Rico reg'd cars: it is Fed law on CatCons for 8 yrs, 80K miles.
For California cars, it seems to read that CatCons are covered for 7 yrs, 70K miles, :confused: , but if "your SAV is between 7 and 8 years old then it is elgilble for extended coverage under Federal Warranty Law..." on parts on the "list", page 39, and on that fooking list is 3 way Catalytic Converter, (for Cali cars).

JeeshhH Murphy...I knew I shoulda gone to law school when I nailed the LSAT, :bustingup

That's what I know/interpret from my '01 Warr. info...

yeah im at 81500 miles. i guess im out of luck. anybody know of a place that sells these oem cats at a cheaper price than the dealers?

Try contacting Crevier BMW..

If it was within the mileage/time limits, the converter warranty would only apply if the converter failed for certain reasons, ie manufacturing defect, etc. It would also likely be covered under the emissions warranty if it was deemed to be consequential damage from the failure of a covered component, ie the oxygen sensor.

If it failed for another reason, for example overuse of fuel additives, warranty would not apply in any case.

This does raise the question of why it failed. If there is no obvious cause (such as continuous use of non-recommended fuel additives) I would have the dealer check out the other systems to make sure the replacement converters did not fail similarly.
