eugopnosaj 0 Posted November 23, 2011 So the Corrado VW ISV part number is 034 133 455b with the Bosch part number being 0 280 140 512. On eBay there are various Bosch ISVs that are identical to look at but have Bosch part number 0 280 140 516. Does anyone know whether they are a suitable replacement and will work?
