The difference its made is amazing, no lumpy idle at traffic lights, plus it feels as if the turbo is spooling earlier, alot more urgency to the engine. Going to be sleeping with semi carbon black hands tonight, but trust me, it was worth it!
Wheres this guide?
How often should it be done?
I don't have idle problems or black smoke but strange hesitation/shake at 1,9k-2krpm
Not having seen the inside of the egr b4 i had no idea of its internal profile. I actually thought that some of the inner profile was from the machining until I stuck a knife in it, it must have been 8mm thick in places.I bet it was relieving to clear out all that carbon? I was kind of disappointed mine was pretty clean.
Went to dealers yesterday and bought a new EGR gasket (£2.35) getting some Wynns carb cleaner tomorrow and hopefully I'll get mine done over the weekend.
