hey people,

ive just fixed my o2 sensor thanx to the help of a few people on this forum, now im finding that im getting another error code (this code existed prior to fixing o2 sensor as well, but were cleared)

Control Module Part Number: 8D0 907 557 C
Component and/or Version: 1,8L R4/5V MOTR AT D07
Software Coding: 04031
Work Shop Code: WSC 06335

ive noticed a bit of a ruff idle when the car's cold

what does this mean?

any advice is more then appreciated...

thanx

car specs :

audi a4 non turbo, 1996 1.8L

 

Engine is knocking.
What gas are you using?
Try using the proper Octane gas from mainline retailers.
If that doesn't work, try a cleaner such as Seafoam, or Techron.

Failing that, move to the next higher grade of gas.

 

im using premiem unleaded 95 octane level

which id say is good for non turbo? or am i wrong?

whats these washers your referring to? what do they do? are they just a gemic or actually work?

by the way thanx for your reply man, i thought no one was gonna reply bcuz it mita been a difficult question

 

Did you clear the knock codes after you replaced the O2 Sensors?

 

well i cleared to codes before i put in the sensor by a few days, then it came back after i put o2 sensor by 2 days, which is today.. should i clear them? or ???

also i must note, i do tend to hear a kocking noise from the engine, sounds like its comming from under the spark plugs or there abouts...

what now people???

 

I would reset them first. And not just resetting the codes with a vag, I would reset the entire ECU by disconnecting the battery for a half hour or so.

 

to reset the ecu could i just remove the negative or do i have to remove the positive too? also im not very clear on how removing the battery will get rid of pinging?

 

Those codes are usually associated with bad O2 sensors. To reset the ECU you just unplug the ground (negative). I really can't tell you if it will do anything, it's a stab in the dark. I am only guessing that your ECU has learned settings and now that you have new O2 sensors in there they don't match the ECU's stored data, causing bad idle. Reseting the ECU when I changed my o2 sensors made a big difference in the idle behavior. Less erratic/more stable.

Make sure you have your radio safe code too.

 

okay ill do that tomarrow morning, hope it makes a difference with the idle somehow, when i did a throttle body alignment after i changed o2 sensor ive noticed better idle, not 100% but better...

does resetting the ecu reset all error codes too? or do i have to reset with vag first?

thanx again

 

yeah it will reset all error codes. It will be as if it came from the factory. You will have to do a TBA again too.
