What do I do?
A few weks ago my egr failed, I got it fixed and drove it home but it turned on the check engine light. I scanned it and it said dirty egr valve. Took it to the dealer for an oil change last Friday and they flashed my PCM while I had my sct programmer installed. They didn't fix the egr valve because I didn't have time. After the new Ford flash my truck through another code since it doesn't have the dpf, no biggie. I put the dpf back on and took it to the dealer to have the egr replaced but since it was reflashed they couldn't find the trouble codes. Now they want to charge me $220 for a diesel diagnostic check, but I don't think I should have to pay since they didn't fix anything. What should I do?
