VW ECU Up for sale is a Working, in excellent condition VW ECU. Bosch Part number-- 0 280 000 048 and 311 906 021 E / CU 15X - This is a used factory (Bocsh) remanufactured unit. . This ECU came out of a 73 VW VW Squareback, but may also fit Bug / Beetle though my list shows this should also fit 72 & 73 VW Squareback. 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 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 electronic components like this one, there is no warranty beyond that. Price a rebuilt unit, 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.
