tr VW New beetle ECM / ECU Up for sale is a Working, in excellent condition VW New beetle ECU. This is from a 2005 model. My list shows this fits all Federal emission 2.0 manual trans cars however may fit more. Part numbers listed at top. This unit offers a 30 day functionality warranty. This should fit others too, & as always with this type of component your best bet is to match the part number to the one on your original ECU. 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 as well as emission control & cold or hot start problems. An erroneous check engine light is especially problematic, as the car will not pass the emissions portion of the test at the annual state inspection.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. New beetle ECU's are located under dash board behind the instrument cluster. They are easy to access by popping the upper panel off.
