I thought I'd do some pre-remap checks last night on my AMK S3 but as I don't have Vagcom I got a buddy of mine to scan it with the snap-on scanner his garage uses. Good news! No fault codes showed up, so i thought we could try and get a gs-1 reading and managed a 170.9, which if I understand correctly gives a rough power figure of 213.63.
Whilst thats all well and good and I'm very pleased with the result that does seem to be a tad high for a 9 year old car. Does any one have any experience of snap-on diagnostic tools? can they be relied upon? I just don't want to drive to r-tech and then get turned away .
