I've seen a lot of issues occurring after the emissions fix - should I get it done to my Volkswagen Tiguan?

I have a 2008 Volkswagen Tiguan 2.0 TDi DSG. I've received a letter asking me to bring the car in for the software update. However, I'm worried about the problems other owners are reporting once they had the software update - such as ERG valve failing, economy of car worsening and fans running continuously after the car is parked. Is it compulsory to have the update? Will my car fail the emissions test if I don't have it done?

Not compulsory. VAG dealer will usually warn you off having the fix if your EGR or injectors are too worn to function properly after the fix. BBC Watchdog told the world last Wednesday night that VAG would guarantee no problems after the fix up to a mileage of 160,000 miles, but that assumes the car was fit for the fix in the first place.
