BITCH is back...stupid Lambda sensor

From my previous post, you can see the CEL is being a pain in my ass.

After changing some rubber hoses, on the 04/05/2013 i also changed the exhaust gasket along with the turbo gasket.

From that day, the CEL never came back on until yesterday morning. When i saw the light, the amount of words that was running through my mind was just unbelievable!

So after taking some Xanax (just kidding), managed to calm my self down and decided to visit Wyn AGAIN to see whats the problem is this time.

When i went there Wyn was also surprised to see that the CEL is back on (some Chinese cursing words did run trough his lips). 

Plugged the diagnostic tool via the OBD2 and found that its the same error. From the device its shows that the front Lambda sensor's reading is fluctuating. 

As usual image from Google and not mine : - )

It was reading -14.xxx then it jumps to -55.xxx for every 0.5 seconds...and the other sensor at the back has a steady reading of -13.xxx (cant really remember the figures, but you get the idea).

According to Wyn to replace this sensor its going to cost me RM600 ++, which is a Bosch. Original from FA will set me back to RM1k ++ and the only difference is the Volvo logo on it.

So for now, he removed the sensor, gave it a good back scrub and fixed it back. Shall wait and see for how long till the CEL comes back on. 

The idea here is, if it comes back on fast then it may not be the sensor, as it is usually some air leak but if it comes back after some time then it could be the sensor itself - well this is his theory.

So will just have to wait and see what happens, in the meanwhile lunch money need to cut down to accommodate a new sensor as i know sooner or later i will still need to change it.

PS: I also made a call to a volvo supplier to check the price. Sensor cost RM 600. Rear sensor cost RM 580.

Next things to fix/do:

1. Front Lambda Sensor = RM 600

2. Steering Rack cover = RM 300

3. Belt Tensioner = RM 300

4. Service AC

5. Suspension

6. Bushing

7. All parts related to its arms and suspension

8. Rear passenger power window = RM 1 000 (Better find a used one from the halfcut shop)

9. Tint

10. Multimedia system

11. Rims + Tyre
