Does anyone know the Bosch fuel injector part number for our motors? The return line nipple on my front injector broke. Can this top part be replaced or would I need a new injector?

That problem seems to be rather common on the TDI club site, with TDI's with some age on them. I expect we'll become familiar with this as time goes by. I notice that impex sells the complete return line kit for tdi diesels.
