Hi All,

I own a Skoda Octavia vRS Nov 2005 Model in India. Bought second hand, i was going all fine till the Floods played spoil sport.

Post flood, when i connected the VCDS, i did see 1 error code with respect to O2 sensor:

"16514/P0130/000304 - Oxygen (Lambda) Sensor B1 S1: Malfunction in Circuit

Possible Causes
Oxygen (Lambda) Sensor Heating Bank 1 Sensor 1 faulty
Possible Solutions
Check Oxygen (Lambda) Sensor Heating Bank 1 Sensor 1"

My mechanic suggested to remove the "Catalytic Converter" and check for blockage. And yes, the culprit was the Cat-Con. it was blacked out with carbon, disrupting the free flow of exhaust. 

I was suggested to drive with Cat-Con removed and it turned out good as the car was breathing easily.

The Next Morning, i got to see the "EPC & Check Engine" lights glow. Given below are the error codes.

"17524/P1116/004374 - Oxygen (Lambda) Sensor Heating Bank 1 Sensor 1: Open Circuit

Possible Symptoms
Malfunction Indicator Light (MIL) ON
Possible Causes
Fuse(s) faulty
Wiring and/or Connector(s) from/to Oxygen (Lambda) Sensor (G39) / Oxygen (Lambda) Sensor Heating (Z19) faulty
Oxygen (Lambda) Sensor (G39) / Oxygen (Lambda) Sensor Heating (Z19) faulty
Possible Solutions
Check Fuse(s)
Check Wiring and/or Connector(s) from/to Oxygen (Lambda) Sensor (G39) / Oxygen (Lambda) Sensor Heating (Z19)
Check/Replace Oxygen (Lambda) Sensor (G39) / Oxygen (Lambda) Sensor Heating (Z19)"

and

"17511/P1103/004355 - Oxygen (Lambda) Sensor Heating; B1 S1: Performance too Low
Possible Solutions
Check Oxygen Sensor Heating for Oxygen Sensor before Catalytic Converter"

please help me understand if it is due to removal of Cat-Con? do i have to do some adaptive coding using VCDS to let the ECU know that i have removed the Cat-Con?

Thanks in advance

Note: Mods, Kindly merge my topic under any such existing topic/post. sorry for the inconvenience.

The system is looking for something that should be present on the car, and as it is missing, it is throwing up error codes. I would think your only options are to either -

 

1: fit a new cat and possibly a lambda sensor too as the flood probably did not improve that item's well-being at all.

 

2: Get the car ecu mapped to have the lambda sensor removed, but I'm not sure that may even be possible, as the engine fuelling depends so heavily on that component.

I vote for number 1

Thanks a ton.

 

Will do this and post the updates

hii i am also a vrs user,

you must have removed the cat-con and directly inserted into your straight pipe,your car has gone into limp mode,its because the o2 sensor is reading wrong reports that has installed in the ecu from company,just do one thing,

1:the only option is you have to have to install the cat thats one solution in cat there are 2 filters one big one small you can get that big filter remove that will give you 10%more horsep. without blowing the engine sign.

2:other option is i have heared that there are sensros available that provides physudo readings which i am doing research on these days this will allow you to use straight pipe without engine sign blow, in superbikes these sensors are available i am looking for vrs now.
