Hello
This is my first post so please be kind. I have had the usual trouble with hunting at idle on my M Reg 80 Tdi. I have had some vaccum hoses changed which did not seem to make to much difference. the original fuel pump code is 0460 404 992, I managed to procure a replacement pump 0460 404 983, and have been advised that it was just the electronic part of the fuel pump that could be faulty I have swapped this over. Connecting everything as it was before, Luckily the car starts fine but after a while the juddering and hunting kicks in with more force ( I have not driven it yet)).. So my question is could this be a faulty recon pump? air in the system? fuel not getting to to a certain part where it is needed? or a timing issue?
any help would be more than appreciated
thanks
Scott
