Hello - welcome to the forum! - in what way is it worse than ever - please explain?
hi bud, ive got an 09 focus tdci (similar), anyway i got this code up p042 which indicates egr, so cleared the code with my scanner, it was running as though the turbo wasnt booting in so i put this stuff in tank which i have used for years even on old cars and i swear by it, its called forte you can get for petrol or diesel and put it in when you have 100miles left in tank as it will be stronger, thats what i done only last week and is now running as new again good luck
Thanks for that might try,the mechanic says its the engine full of sludge???
not a very technical explanation. is he a 'proper' mechanic... :ph34r:
