All,
I come from the z3 M Coupe world and fully understand the question I'm about to ask has probably been answered a million times. As the title suggests, my father passed away and I've got a 2000 M5. The car is in Florida where there is no state inspection. It has a check engine light on. Unfortunately, I'm from the northeast, so if I want to drive it, i have to get it to pass inspection.
Free autozone scan returns the following:
PO411 secondary air injection
PO420 cataqlyst effeciency below normal: BANK 1
PO430 Catalyst effeciency below normal: Bank 2
I understand Carbon Build Up is probably the cause of the first code and is very expensive to have BMW fix. I also understand PowerChip software will get rid of this code. Is that the best route to go? They've offered me their holiday sale price...can't really complain.
The second two are most likely bad O2 sensors or clogged cats. My father was a little cheap and it wasn't until recently that I got him to switch from 5w30 to 15w15 to TWS. The M5 burned a lot of oil when he ran the thin stuff. I'm guessing that could have clogged up the cats. If so, i can handle cutting the cats out and putting some aftermarket ones in as well as changing out the O2 sensors. I've got access to a shop and a lift...
Anyway, any help is much appreciated. I'd love to get the M5 back on the road as my daily, keep the 01 M Coupe in the garage for fun, and sell my cash for clunkers Honda Fit!!
Regards,
Scott
