    Beetle oil over fill.

    Hi all,

    My neighbours 2007 Beetle 1.4 BCA Luna came home on the back of a low loader last night, she's just asked me to take a look at it. She claims that the oil light started flashing before it died on the motorway. When I checked the dipstick expecting to find no oil, to my horror there was almost twice as much as should be. I've drained off about 3.5 litres, started it up and all seemed fine.

    However once you rev it up the oil light flashes but goes away on tickover. I've switched it off and told her not to start it until I've finished investigating further. I'm guessing she's popped something and has little or no oil pressure however I can't be certain, would anybody have an idea I can follow please?

    Cheers
    Alan.

    You need a good oil pressure gauge fitting to make sure it has good oil pressure. No oil pressure don't drive car else you will need another engine. Then you can check all wiring and connections then replace the oil pressure switch.

    I'm not sure is that 1.4 is the same as others talked about in here. The oil pickup pipe in the sump gets blocked with crap. Crasher will tell you more when he reads this.

    Over filled have they put to much oil in and not checked the dipstick. Or over filled because access petrol is being washed down the bores and making the oil level higher.

    The overfilled oil may have gone into the breather and then though the combustion process, into the exhaust and contaminated the lambda sensor hence the engine light. It MAY not have a pressure fault, some people misinterpret the level check yellow oil light and this can give the wrong info if the bonnet opening switch fails so the inexperienced just keep adding more and more oil. The red oil light is the ohh **** one.

    Hi Keith,

    Thanks for your reply. No she has been topping it up thinking it was the right thing to do as she thought that "cars always burn oil don't they?" Just wondering if the excess oil pressure could have killed the oil pump?

    Thanks Crasher, the engine did sound rattley when I started it so I'm guessing that there's some damage there?

    Is the red warning light on when the engine is running?

    Sorry for the late reply Crasher, I've been on nights. My neigbour took a chance driving the car to work, she said that the red oil light kept flashing and beeping until the car stalled, she tried to restart it but said that the battery was flat. I've just tried it and it fired into life so I suspect that it's gone tight due to no top end oil feed. It had the usual BCA rattly sound when it started but did quieten down after a short while so oil seems to be going somewhere?

    So I've been trying to locate a good BCA replacement engine for my unlucky neighbour to no avail. Plenty out there that have already been ripped down from the car but there's no way I'm taking a chance on one of those for her. What I have stumbled across is a really sweet BCY engine with 31000 on the clock. My question is what are the fundamental differences, will it fit a Beetle and what will I have to do to make it work in the Beetle? Thanks.
