My wife's car (1995 BMW 525i) has been slowly losing power and having reduced fuel economy over the last 18 months. I rarely drive the car. 2 years ago, it got about 32mpg on highway trips. Yesterday, I drove it for about 150 miles and only got 25-26mph.
It is down on power and very occasionally smells like a morning-after Guiness-fart. I am 90% sure that the cat is shot. I priced OEM replacement cats and every source I checked was in the $485-$500 range (yikes!). There is also the obvious choice of getting a universal cat and making it fit... How can I be absolutely sure that this cat is bad? I'd like to be completely sure before I commit the time and potential effort on this. Thanks |

....could ALWAYS sell the BigMoneyWaste.... (IMG:http://www.frrax.com/rrforum/style_emoticons/default/rolleyes.gif)
Two things made me realize I will never own a BigMoneyWaste again shortly after dumping our 2000 528.... 1. The service manager looked me in the face after having the same problem for 2 years and said..."Have you ever owned a BMW before?.....These are precision automobiles with a lot of high tech systems, and things like this are common..." 2. Right after that he told me how much my next service was gonna cost me...until then we were on the FREE service plan....
