Hi, yes the refinements are great but if its a CNHA engine or any of its derivatives for that year you will inevitably come across EGR cooler problems and MAF/MAP problems I ran mine over 270k as a taxi and believe me I ran in to a multitude of problems during that milage, the worst being the EGR cooler and its valve which are a nightmare to change then you have the clutch, parts are hard to get hold of unless you want to get them from Audi my first one was £1900 for the parts alone and only about £100 cheaper on subsequent changes, around 100,000 miles the game becomes interesting with things like oil leaks around the sump and oil level sensors packing up, you can't beat a dipstick, then there is the silica bag in the expansion tank which ruptures and kills the heater matrix if you dont get at it a bit sharpish, drive shaft outer gaiters tend to be a problem as well, never had a problem with the adblue as I used so much I dont think it had a chance to crystallise, lovely drive but expensive parts/labour even at an independent garage because everything major is so hard to get at, as for the nature of forums thats just the tip of the iceberg, the majority of owners who have the problems with EGR coolers and clutches just sell the car when they find out the cost of the repairs, I am lucky insomuch as I did most of the repairs and have an excellent rapport with my local garage for clutches etc.
