    Hi I am looking to swap out my engine for another 1.6 FSI.

    Looking at ETKA there is a few engine codes I can use BKG, BLN, BAG, BLP, BLF.


    They only noticeable difference I can see is with the fuel pump and fuel lines......

    See images below.


    My BAG Engine code variant has the older style HPFP with 4 mounting bolts and 3 lines / pipes coming from it (the newer ones have only 3 mounting bolts and 2 lines / pipes coming

    from the pump).


    Looks like mine has additional breather line? The fuel tank images from ETKA also show 2 options for part number 3 (or 3A) - where it either has 2 lines / pipes or 3 lines / pipes.

    Would one be redundant or would I need to remove the additional pipe? Or do I need different fuel pump (LPFP / in tank pump) and fuel tank to be able to retrofit this engine?

    Will there be any issue retrofitting another engine to my vehicle?

    Will anything need to be coded or paired? Or is it simply a straight swap?


    Appreciate any help.

    Thanks.

    A quick look shows the pre 2005 BAG had different cams so if yours is a 2004, the late cams may upset the ECU.

    I think with the early cams the ECU may get confused, the HPFP SHOULD just be a matter of fitting the later type but these ECU's are so sensitive I have seen them object to even having the slightly incorrect gearbox fitted.

    Ok so it has to be an early BAG engine which is the one with the square / rectangular looking silver HPFP? With 4 x mounting bolts?

    from what I can see the later HPFP only has 3 mounting bolts....

    therefore also has a different rocker cover?

    guess that means you can’t swap rocker covers and cylinder heads over?

    I can't see a problem in swapping the heads.

    Got myself another BAG engine from an 8P Audi...... done half the mileage that mine has..... ~100,000

    Same early style fuel pump on it too which means I can transfer my ancillaries onto this engine.


    Looks like its had work on it already.....new chains (oil pump chain and timing chain), new chain guides, new tensioner....

    Also looks like a new head gasket.....it also had a VW parts box with roller coc on it (036 109 411 D) so think some cylinder head work has been done too....new rockers, tappets etc.....

    Intake valves look super clean.....either new....or have been walnut blasted / cleaned.

    Exhaust valves don't look like they've been touched though?


    What checks should I do on this other engine to ensure it is ok prior to fitting?

    There isn't much more you can do, good luck with the fitting.
