If you have a computer you can get an OBD ll tester that can pretty much tell you the codes for the check engine light. I bought mine off-line for about $60.00. Nice thing is you can also reset the check light from here. Mine in the beginning were lean code. That was a caused by a hole in a rubber boot of my intake. The DSC light I have had several times. That was reset by removing the wheels & cleaning the wheel sensors.

It's either the connection to the driver side rear wheel sensor, or the sensor itself. See if you can disconnect it and clean the components. It's a touch tricky getting the sensor out of the wheel hub, but I resorted to a hook made from a screw driver. Good luck.

DSC and Check engine lights together

reviving an old post here as I am having a similar problem - 2004 525i with 6 speed manual -
check engine light and DSC come on together and car loses all power but does not shut down.
Always seems to happen to me while ASCENDING a hill and car will not rev about 1000rpm. Turn car off, wait 30 seconds, restart and drive away with no problems and no lights on dash.
This has happened maybe 10 times over past 60 days but never before that.
Had one person guess it was the DSC system freaking out, another ran the codes and told me that both catalytic convertors need to be replaced. BMW dealer said it sounded like a transmission sensor and asked me to bring it in for a diagnostic.
ANY thoughts would be most appreciated and thanks very much!!

First, you should probably post in the appropriate forum for 2004's, rather than in the e39 forum, where people with similar cars will be more likely to have similar experiences. Having said that, however, this sounds like a classic case of clogged catalytic converters. You might want to do a forum search of clogged cats and see what it turns up in the way of diagnosis. I'm guessing you have more than 100,000 miles on the car.

thanks!

Thanks and sorry for the wrong forum - wasn't sure where I should be...
Yes, going to pass 200K miles in the next few days and the cats is what I was told by
very knowledgable person - just hoping it wasn't so because of the $$$

Thanks again!
