Heavy downpours in the midwest today, driving my girlfriend to the airport (plane then got canelled)... MIL came on, solid light, thought it was another coil pack failure (2002, 1.8tqm)

Get home, no real adverse effects, stop by an auto-zone to get vagged and pulled a P0171- lean in bank 1.

I was giong to go to the dealer hoping it was a coilpack misfire, but lean is usually an indication of MAF, no? I do have the 1+ programming and the larger injectors... all the dealerships around (Columbus, OH area) DO NOT want to deal with chipped cars... should I take it to the dealership and take my chances with warranty or should I deal with the local tuner (hour and a half away) and APR (ugh)?

anyone else get lean MIL's on their B6's?

any insight would be great, thanks a lot guys!

I was completely underwhelmed with the apr 1+, and this is just the icing on the cake

Im sorry man i dont know what to tell you

I think it is the 02 sensor, if you have a vag check you lambda readings. I have just ignored the code. I called APR about it and they weren't too much help. I have had my 02 sensor replaced twice, maybe this time I will try the MAF see if that does it.

I'm not seeing CEL/MIL posts for GIAC, MTM, etc.

what injectors they use.

much air in it. It COULD be the MAF, giving a reading too low and thus the ECU commands too little fuel. I would work with your tuner/APR. They are responsible for the performance of the 1+ upgrade, and it shouldn't set a code.

Btw, you won't be doing any damage to your car by running lean, but you may not experience all of the performance that you should be getting with the 1+.

not sure though.

Another problem with APR. What's going on guys? Get ABT or MTM until they work the bugs out.
