BMW Z3 1.9 Catalytic Converter
Hey there group. I was wondering if anyone has any advice on catalytic
converters. I've searched near and far for detailed information on replacement parts and there is absolutely nothing. As far as I can tell I have three choices the BMW replacement part ($1100 ouch), the Miller part ($746 ouch), and the DEC part ($346, I can deal with that). I want to know if anyone has any knowledge of these parts or any experience replacing this unit. I'd hate to dump a ton of money into the car and find out the part I bought was total ****. If anyone can lend any information it would be of great value to me. Also if anyone has any tips of replacing this unit I.E. other parts I should buy/replace at the same time, tips, tricks, pitfalls etc. Thanks! - Broken Z3 owner |

BMW Z3 1.9 Catalytic Converter
I've been doing some research on this group and other web sites and I'm
just not convinced the aftermarket is a safe alternative. With the parts not fitting right, and the pipe restrictions, and possible O2 sensor snafoos I am just thinking I am going to have to bite the bullet and go with the BMW part and have a pro install it. Uggg..... How often do catalytics fail and what causes such failures? I run my car pretty hard, IE high revs, cornering, etc. (drive it like I stole it I always say). Any ideas? - Broke Z3 owner.

It is important to determine what caused the converter to fail, so that the problem can be fixed and to prevent a recurrence of the failure. It can be difficult to determine exactly what caused a catalytic converter to fail, but the following failure descriptions will help narrow down your search for the malfunction. http://www.bmwe34.net/E34main/Trouble/Catalyticconv.htm |
