I would like to ask if someone has cleaned up the lambda sonda. My car has sometimes a very high comsuption, and i think is is not related to FAP regeneration. I dont know whether is possible to clean up the sonda or I have to buy another one directly. Cheers

I just cleaned my EGR valve and a couple sensors today and the car's accelerating like a rocket once again.

Clean it up. it's super easy.

How did you clean the lambda sensor up? Cheers.

Unplug, spray some WD40 on it and then plug it back.
There should be a ton of tutorials about this on the internet.

Today I have cleaned the lambda sensor up and the car is working worse than before. The consumption has increased a lot. The sensor was cleaned up with a toothbrush, i didn't use alcohol. It was dirty, with very very soot. Any idea. I'm going to check what's happens tomorrow with MES but i dont know what's values aré right. Thanks a lot.

No point to clean an oxygen sensor... there is nothing to clean... most likely you damaged it now

Just replace it with an original one.

It seems that.... But i dont know How it is possible to damage a sensor with a toothbrush? I cannot believe it.
I think after 260.000 km the sensor was at the end of live.
Is it BOSCH the original one? Does anyone know it?. Thanks a lot.

Of course you damaged it.
You should clean it only with liquids not by pocking stuff in it.

Ok. Do you know whether BOSCH is the original one? Tomorrow i will buy it. Thanks.

Probably. bosch is fine.

MAF, MAP, and lambda sensors are very important in motor function so dont buy aftermarket even the originals sensors are expensive.
Others sensors you can buy they aftermarket.

Totally agree. This morning bought a new one from Bosch, 130 euros.

Money best spent in my car so far.
