Hi all this will be abit long winded, ive got a seat leon which has the 1.6 AZD engine my car broke down few months ago and wouldnt start andv when it did it ran like a dog with 3 legs , so i took it to a garage who hooked it up to there computer and a number of faults came up including system bank 1 to lean ,voltage short to B+ (didnt know what that meant really), random misfire and a number of other faults including EGR and lambda so the garage replaced my EGR and lambda cleaned my TB £750+VAT later my car was running perfect apart from running 0.01% lean at idle the garage decided that this is down to me having an aftermarket induction kit fitted which to be honest has been on the car 2 years and had no problems .
So one month later as i was going to Blackpool (ok i did hit 110mph at one point) my EML came on so i called AA out and the fault code came up sayin system to lean which id suspected considering it was lean at idle so must bit alot more lean at 110mph . so anyway had that cleared few weeks later EML is back on so i call AA out again fault now is EGR and lambda whish was replaced with Brand new parts direct from VW so i had them cleared once again ,a few more weeks go by my cars idle starts becoming erractic when warm to the point where it shake the engine and cutting out when steering applied ,only on certain days tho and after a long drive other days its fine o and EML light on again .now im in a dilemma really my cat has decided to melt its insides so its rattling like a metal ball inside so need to have this fixed before i go back to the garage as i know they will prob put that as the cause the same way they tried sayin my induction kit caused the other problems.
My question is will my aftermarket filter affect this and what can i do myself to check this idling problem im sure it cant be EGR or Lambda as there new they have got 12 month warranty tho just in case
any ideas would be so helpful o and just another quick on thinking of just gettin a decat some one told me there a cat in the manifold is this true?

, Also rough idling i would assume coilpack were hey all replaced when u had the missfire problems, and many people on here say dont use oil base filters as they ruin the maf so maybe a maf issue
