excesive

cleaned out my egr valve on my leon tdi 150 the other day, when i got it off found it really caped in crap, now it is back on it smokes twice as bad. big puffs of black smoke when ever i boot it. looks embarrasing when driving lol. anyone had this before on their leons if so what was it?

I have had my car (Seat Leon reference sport with the touring car kit) for 12 months, it runs on 18 inch seat rims. Since purchasing the car the road noise has developed dramaticaly coming from the rear of the car. I have also noticed uneven tyre wear on the inside of the rear tyres. Has anyone...
