Oxygen Sensor Replacement: P2247

Oxygen Sensor Replacement: P2247
(E90 330I 2006 BMW)

This time I am going to tell you about Error code P2247, which is Bank 2, Sensor 1.

It actually gave a "Check Engine Light", I plugged in my error code reader, and it actually also gave me error code P0155, as well as P2247.

Replacing an Oxygen Sensor is not very complicated, but it does require a special tool.  An Oxygen Sensor removal tool, you can borrow from Autozone, if you buy the Sensor from there.  Here is a picture of what I got:

NOTE:
you have to run the car To Temperature for the car to recognize that it's a new Oxygen sensor: 
- I ran my car for about 5 minutes,
- Turned the car off, and back ON
- Then cleared the code
If you try to clear it too soon, it will not work.  Be patient.

Which sensor is Bank 2 Sensor 1: It is the sensor that is closer to the firewall, on top of the engine.  Pre Catalytic converter.

NOTE: 
Bank 2 Sensor 1 is : Gay color (cable harness) (Code P2247)
Bank 2 Sensor 2 is Black Color (cable harness)  (Not sure what code is)

Faul codes

Note the color of the cables on Sensor 1 and sensor 2.  Bank 1 and 2.

Remove Heat Shield:
To get to the Bank 2, Sensor 1, you have to remove this (Heat Shield):

You have to remove this, otherwise there is no room to put tool on the sensor

Note the Length too, it's not a short wire harness, NOTE it's gray color.

Bank 2 sensor 1, is the one on the left, to disconnect.
You can follow it back to see which one it is.  If you are not sure.

Good luck replacing your sensor, thank you for reading my post.

Windshield Wiper Fluid Reservoir Nozzle "Replacement"

Windshield Wiper Fluid Reservoir Nozzle Replacement
E90, BMW 330i.

A few weeks ago I started getting the windshield wiper fluid warning, and as I usually do, I go down to my local Autozone to get a new bottle, they are usually not that expensive: Windshield wiper fluid at Autozone, no big deal.

Amazon link below...

Just like I always do I got home and I poured the liquid in, again... no big deal.  But this time it was not so, because after only a few days I got the same warning again. 

I was able to confirm I didn't have any liquid when I tried using the windshield wiper fluid and none came out.

I was scratching my head, this made no sense, what is going on here...  

Unfortunately there is no way to get to the fluid tank without removing the Right side Tire, and the shroud to get to the bottle.  I also knew it could be the motor that was going bad, but I could hear it running when I engaged the switch, so I figured that was ok.

So what was the problem, old rotted plastic hose, 

Only thing to do next... to remove the tire, and shroud, once I removed the shroud I could see the leak, and I began to unplug it. you just pull on it to disconnect, it does have a black rubber seal, the seal was old and didn't do it's job any more.  The new one worked great.  Simply disconnect the old and route the new one.

This was the problem, where the leak was.

 I have to say the most difficult part of the entire procedure was removing the plastic shroud, there are plastic rivets, that really gave a hard time, I ended up obliterating them to get the shroud off. there is plastic part in the middle of the rivet, push it in and it will help you remove it, I suggest you replace them with new ones.  This will save you a ton of time.

BMW part # 61 66 7 135 409

Side note: Make sure to remove the top lid of the old hose, because it doesn't come with it in the new hose.
