    Golf Gtd smoking badly from exhaust

    Hi guys
    I was wondering if anyone has had the same issue
    turbo was replaced and the car then began to smoke from the exhaust quite badly,the garage got the DPF cleaned out and had replaced the injectors to no avail.
    It then went to another place for a new map and they found the injectors were not seated correctly so recut the seats and the car ran great for 3 or so weeks,then the smoke returned and its getting worse day by day.
    It still runs fine with no logged faults and the engine runs well,its covered 100k but I have never before had this issue,all the pipes and the maf have been checked
    does anyone please have any suggestions to what else could be causing this,any help would be greatly appreciated

    Is that blue smoke oil being burnt or white smoke water being burnt?

    You need to get your motor scanned (preferably with VAG-COM\VCDS) for any error codes logged in the ecu and post them, that will save a lot of guessing and check systems out.

    More than likely the injectors are damaged, that sounds like poor fuel atomisation, running it like that will block the DPF. Where did the “new” injectors come from and how much did they cost, fitted?

    Did they enter the IMA coding for each injector into its appropriate block in adaptation?

    Could you get the part number off the top of the injectors? It is quite visible and starts 03L. Also, private message me your registration number.

    They are the correct injectors for a CBBB 170PS engine, difficult to say where to go now but it still sounds like the injectors.
