Had Luckett turn up today to clean his EGR valve and boost sensor, 56 plate Twintop with 65K on the clock and I think he had about 65k 's worth of crap on the EGR

Got it clean and refitted, just waiting for him to report back on MPG increase etc now

Gotta say though, the Wynn's carb cleaner in the old style cans doesn't last long.
