hi, im new here bought an s2 auto rs4 other week because it was cheap + ive always likes them.
anyways noticed twice now engine light comes on stays on for maybe 10mins then goes out, 1st time i was into it abit but 2day was just cruising along, doesnt mis or anything and checked the basic things and all looks good. its running stock cooler and exhaust, only mods being front shafts out and 4wd fuse near battery out, has a boost T runs around 8psi spikes to maybe 10max, and has a wire cut from factory boost sensor near turbo and that wire is now earthed. guess that allows for boost increase?
any help or direction would be great.
jon.
