VW / Porsche ECU Up for sale is a Working, in excellent condition VW / Porsche ECU. Bosch Part number-- 022 906 021 B / 0 280 000 015 . This ECU came out of a 72 VW 411 - but should fit other models too but as always your best bet is to match the part number to the one on your cars original ECU. These D-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 "antique" electronic components like this one, there is no warranty beyond that. Price a rebuilt unit from Bosch, 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.
