Oxygen - O2 Sensors
 

Well, my dealer told me the reason the SES light was on was that both of my down stream Oxygen Sensors were bad. They would be happy to set me up with new ones installed for the mere price of $660... wow !!

I found two brand new ones on Ebay for $100 total vs $400 from the dealer. My local Sunoco, which happens to be a decent shop, installed them for $170. I figured they are just O2 sensors and this isn't isnt a job that a Euro shop or a dealer has to do. So for $270 I was out the door and saved almost $400.

The reason I am posting this is so anyone else needed to get this done knows there alternatives to spending almost $700 to have O2 sensors done. I know these are high end autos and things aren't cheap but there is no reason to be stuipid either..... ;)

$170:wow: I say you still overpaid. I replaced all 4 laying on my garage floor in about 15 minutes.

LMAO... was it that easy???? Where were you when I was looking for a DIY??

There's ALWAYS an alternative to going to the dealership.

Ever check out how much 'they' charge for a "BMW Battery?"

Yep, that easy. Just unplug the O2 sensor connector and unscrew. Screw new ones in and reconnect...

which o2 sensor did you replace?

Hi,

I need to replace the two front O2 sensor on my 2003 4.6is. Parts for the front O2 sensor is relatively cheap. However, is it that easy to replace as djbock might have claimed. I can any DIY on this. Your help will be greatly appreciated.

It is the kind of thing that is very easy if the car is up on a lift. I bought the sensors on Ebay and had a local garage install them. Might have charged me $150 - $200 which I thought was pretty good. One of the holes the sensor goes into stripped so they had a lil bit of work to do.....

Hey thanks man,
I've been quoted 267.49 by a local shop to have it replace. After my research, it's a little bit of a work than I had thought but very doable. The way the O2 sensor is connected, you have take take few things apart. I'll just have the shop do it. Thanks again and keep that 4.6is of yours humming smooth.
