The 043 is the correct replacement, should be Audi part number 035 133 551F.
These are viton tipped and replace the previous metal tipped injectors.

Have you reset the mixture?  This would be necessary after changing the
injectors.  They don't actually shut off in the CIS system, they continually
inject fuel.

Check the mixture first.


BTW, how much did the injectors cost?  I have an intermitantly leaky
injector.  Anyone got a good source?
