Hi folks. I am having idling problems with my 1990 300te wagon. It been diagnosed as having need a new O2 sensor. The mercedes dealership wants 330 canadian dollars for the replacement part. (approx 280 usd).

I have looked around and can find a Bosch replacement from many places online for about $130 usd and on ebay there's one for $35 usd. The seller describes it as "O2 OXYGEN SENSOR BECKARNLEY SG505 M. BENZ 300E L6 3.0 Item number: 8051482403 this item will work great on 90 MB 300te"

Is this a reasonable 02 sensor to buy?

Much appreciated.

IF the sensor is a NEW 3 wire O2 sensor it will work!

Autopartsonlinecanada advertise this item for $170.00 CDN. Shipping included. My experience in ordering parts from US sites is very expensive when you include shipping and duty charges.

Indeed its a 3 wire 02 sensor. The item number is 8051482403 and I just checked the price - $19 usd. Seems like a steal.

Is there any trick to installing an 02 sensor. If not, I might just do it myself.

Thanks again for your responses.

ebay has bosch 3 wires.. 34 shipped... i have bought one just to have in the spare parts arsenal.

with two 17 year old cars....got to keep adding to my spare sparts bin.

Be sure to tell your supplier to send it by MAIL !!!
UPS or FedEx will screw you for $ 30.00 just for clearing it through Canada Customs & handling fees.
I always get small items shipped that way.
