2000 AUDI A6 4.2 WITH A CHECK ENGINE CODE OF P1130...SOMETHING TO DO WITH FUEL AIR SENSOR? ANY IDEAS AND HOW TO FIX THE PROPLEM.

THANKS,
PHIL

 

is it what it read?
P1130 - Long Term Fuel Trim mult.,Bank2 System too Lean
are yuo not gettig P1128 too for bank1 system too lean?
I know someone who had both codes, dealer replaces MAF and sensor.
Are you running K&N air filter?

Check Vaccum line

 

NO just P1130 code. Don't have a K&M Air filter...recently replaced with Fram.

Thanks,
Phil

 

Does it ride rough or normal.
if it is a torn vaccum line on the secondary air system, which isvery common on all VAG vehicles, it will be ok to drive it. It doesnt effect drivability. Just more of an emissions thing.

 

 

Yes, vehicle runs fine. No change in response since light went on.

 

Could be a vacuum leak or an O2 on bank 2. The ECU is looking at the O2s and sees it has been supplying more fuel to that side for awhile. I would check for vacuum.

 

Will do...thanks

 

What was the outcome? I'm seeing similar codes now...
