my brother has a 98 passat 1.8t. a cel came on few weeks ago and we thought that it was nothing big. well it came back today also.

17544: Bank 1 Mixture Adaption
(Add): system too lean

im thinking the o2 sensor or the maf? is that correct or im i wrong? let me know asap. my dad is flipping out over thing since he doesn't really know much about cars.

Thanks.
