    What colour is the oil on the dipstick ?

    “Mayonnaise” at the top of the oil filler neck is not uncommon on these vehicles, based on previous posts. It doesn’t automatically mean head gasket failure.

    Do you have any black residue in the coolant reservoir?

    Oil on dipstick seemed ok, but the neck of the oil filler is almost blocked with thick grey colour mayo

    As ridiculous as it sounds, this appears to be normal. If you look at the linked thread above, there is a picture of mine on the page which VW says is normal.

    There is a VW TPI about this, its normal for most people unless you have the engine running HOT for at least a few hours every day, and not just short runs.

    Customer statement / workshop findings:

    White paste/foam/sludge in oil filler neck.



    Technical background:
    Because of its high efficiency the engine EA288 has low waste heat. As a result, the temperature is too low for the water in the filler neck to evaporate. The big temperature difference of the filler pipe/cap to the remaining
    system/oil circuit leads to increased condensed water formation on the filler neck/cap. The resulting emulsion (of oil and steam) is deposited as oil sludge.
    On the EA288 engine in the Caddy, T6 and Crafter the filler neck/cap is positioned directly in the air flow (no engine cover panel). This assists the condensate formation. Production change


    - Measure
    Explain the following background to the customer: The big temperature difference of the filler pipe/cap to the remaining system/oil circuit leads to increased condensed water formation on the filler neck/cap.
    The emulsion on the filler pipe/cap is must therefore be regarded as normal. A repair is not necessary. But the emulsion can also be caused by external water supply, therefore the following points must be observed.
    • To rule out other causes check the oil and coolant level.

    Yeah, the reason I ask is there a friend of mine had an O-ring failed on the oil cooler and this allowed oil to go into the cooling system and his symptoms were black soot and oil appearing inside the reservoir.

    Yours does sound more like a faulty combined oil sender unit.
