as i said in the previous thread, i had a crack gas valve that also took 3 trips to the dealer in 3 weeks to finally have it fixed. the "service engine soon" warning light came on all three times. at first, they think it's a problem with the OB computer, so they reprogramed it. but the SES light came back on after 30 miles. i did a search on MINI2, found that someone else had the same problem with the SES light, and it was a faulty valve. when i took the car in to the dealer, i asked them specifically to check out the valve. problem's fixed, and it's been running great now.
wouldn't have this problem fixed so soon if it wasn't for fellow MINI2'ers.
