I have a check engine light with a recurring code, 17538/P1130.

When I pull the code and copy the data and paste it in a document it states:

1 Fault Found:

17538 - Fuel Trim: Bank 2 (Mult): System too Lean

P1130 - 35-00


But when I look the code up in the Bently, it shows:

P1130
17538
Long Term Fuel Trim mult., Bank2

System too rich 1)


My question is: Do you know if this code is actually a lean or rich code? My Bently shows the lean code as 17546/P1138

Thanks!

You should try AudiPages.com lots of good info there (snicker snicker)

But it says lean on this page http://www.bentleypublishers.com/tech/audi/audi.dtc.table.htm<ul><li><a href="http://www.bentleypublishers.com/tech/audi/audi.dtc.table.htm">http://www.bentleypublishers.com/tech/audi/audi.dtc.table.htm</a</li></ul>

After searching on audiworld, I was coming to that conclusion.

I have a fairly recently updated Bentley, and it says too lean.

Under the diagnostic codes portion where it just lists the fault codes, it shows it as lean.

Under OBD under the engine, it shows it as rich. Just a mis print I guess.

of your vacuum lines, or just the one you mentioned below? The reason I ask is that the code you show is on the <a href="https://forums.audiworld.com/a8/msgs/165940.phtml">TSB list</a> for bad vacuum lines.
If you did all that already, then nevermind...

going on
The code with the next number is rich ie:
17535 = rich on bank 1
17536 = lean on bank 1
so I assume that
17537 = rich bank 2
17538 = lean bank 2

I had the lunch meat post code, the vacuum line was disconnected, I fixed that.
