Re: Still lambda issue after new catalytic converter

Mogelijke oorzaken:
Kortsluiting in de referentiespanning van de lambda-sensor
Lambda-sensor vervuild of defect

It's not really unsafe to drive with, but you'll probably miss a few horses and use some more fuel in the process.

Seems that the heater coil inside of lambda sensor is kaput.
What brand of lambda sensors dis you put on your car?

Bank 1 sensor 1 is the sensor upstream of the catalytic converter. Bank 1 sensor 2 is the one downstream of the catalytic converter.

NTK is the brand name for NGK sensors and tends to be what VW Group fit at engine plants and sell as spares.

Maybe things have changed over the past 10>15 years, but when I checked back then, I found that buying locally from a VW dealership was very close in price to buying an NTK same part online and getting it delivered.

Thats a really useful information.
With sensors, buy cheap pay it twice.
