As always your best bet is to match the part numbers with the original from your car.Have to be sure of proper fitment.  you priced one of these new from an authorized Bosch service center of from your VW dealer? Pay me less than you'd pay in tax alone for a new one!A faulty ECU is one of the most common no start or random stalling problems with these cars. These can also cause issues with erroneous check engine lights, idle control problems as well as emission control & cold or hot start problems. I have also seen fuel pump relay turn on faults (ECU won't turn on the fuel pump), as well as an condition where the high speed injector driver has failed. This causes the car to sit and idle fine, but it won't accelerate.If your car does not have these issues but you intend to keep it a while, I recommend our customers keep an extra ECU in the trunk. These units now have to be special ordered from most dealers new for big $$ (often times over $1000!), and you can never find one when you need one. Even now finding a good one second hand is getting to be quite difficult as these cars get older. This is located in the cowell of your VW - Where the wipers sprout out from. Unit comes with a 30 day warranty. If it goes defective, you get a replacement or refund of original purchase price if returned in original condition.
