Hello Fellow E34 Members,
I have 1995 BMW 525i with 206K miles and am looking for a stock OEM catalytic converter for my car to pass SMOG. If you have one or know of one that is in great condition, preferable low mileage, please let me know ASAP.
According to my BMW dealer, the OEM catalytic converter is on back ordered due to vendor part issues.
Long story short after 3 months dealing with my BMW Independent repair shop and now my BMW Dealer to try to pass SMOG, my dealer wants me to reinstall a stock OEM catalytic converter. My stock catalytic converter is no longer good.
I only failed in the 25MPH test on HC. My HC is measured at 44 and the maximum is 40.
I have replaced and performed the following service already:
1. Motor oil
2. Spark plugs
3. Air filter
4. Oxygen sensor
5. aftermarket catalytic converter (magnaflow)
6. fuel injection service by BMW dealer
7. BMW dealer performed diganostic on engine and all numbers looks normal and within manufacturer specs
8. Replaced thermostat and thermostat housing
Please let me know ASAP. Thank you in advance!
