VW ECU Up for sale is a Working, in excellent condition VW ECU. Bosch Part number & VW P/N listed at top . 473 906 021 / 473906021 / 0280000111 / 0 280 000 111 Porsche 914 Engine computer, guaranteed good, should fit the 1975-76 4 cyl. 1.8 engine - this is the car it was removed from. Clean rust free crash damaged car. This ECU may also fit VW 411 models though my list shows this may also fit some 1970-1975 models. It may fit other models/years, but as always your best bet is to match the part number to the one on your ECU. These L-Jetronic ECU's are getting very very hard to come by, and this unit is in great shape. This unit is guaranteed to work on arrival, but due to the nature of electronic components like this one, there is no warranty beyond that. Price a rebuilt unit (if you can find one), and you will see this is a great deal... Don't hesitate to email me with any questions, I'll do my best to answer them.
