I had my Leon Cupra mk3 serviced at my local Arnold Shark last week and checked my oil yesterday to find it's been overfilled, probably by around 3-400ml by the looks of things.

Does anyone have any experience of changing oil on the ea888, if so can you slightly loosen the funky plastic sump plug to let the oil drip out and back down to the correct level without fully removing it?

The most obvious thing would be to take it back down but it's such a hassle waiting for workshop time etc.

Alternatively should I just leave it? The internet generally says no.

Thanks all

You can suck out via the dipstick tube using some windscreen washer jet hose or similar that's sufficiently small to go down the tube, but heavy duty enough that it doesn't suck in on itself. It requires a bit of effort to suck it out - worth trying to buy a decent sized syringe to create the necessary suction. Or buy an electric pump designed to do an oil change from the top. they're not expensive, but will be more money than the suck it out via hose option.

Had to drain a litre out of my S8 after it was over-filled at service. It was a bank holiday, so I used a kids calpol syringe, as I couldn't get anything bigger!

you know anybody with a pela pump you could borrow?
sucking the excess out the dipstick tube with the pela would be the easiest solution.

I actually have a jumbo syringe which I bought for taking oil out of canister style oil filter housings and I'll probably be able to get some PTFE hose from my work. I was thinking about that but I'm not too sure how difficult it'll be to pull out oil...

Why not save yourself the hassle and get the garage to reduce the oils they overfilled?

probably because it's the bunch of s that are arnold clark

they'll want you to book the car in about 2 weeks in the future for a full day. Then despite asking them not to, they'll wash your car badly, adding more scratches and swirls to the ones they inflicted on your car the last time it was in when you also asked them not to wash it.

You've hit the nail on the head there, nothing is simple laugh

Is it a deliberate move I wonder?

I’ve had my 2016 Cupra serviced twice at the main dealer, and they overfilled it both times. I drained it both times, but only after it smoking on start up the second time, which I presume was related to it as it hasn’t happened since (was 6 months ago).

When it goes in next time I’m going to ask if they’re doing it for a reason.

Usually they don’t warm it up/leave it long enough/drain from the sump so don’t remove all the old oil. If you’re lucky they measure out how much oil should go in for a properly empty sump and throw that in the top. Hence, over filled

Some engines will drain oil coolers etc that will only then get refilled once the oil has got properly hit and the valve that prevents cold oil circulating through the oil cooler has opened, so for those a small amount of overfill will naturally drop back to a normal level after a decent run.

Most is just incompetent servicing by people on a tight clock that throw in ‘enough’

I recon it's a rush job rather than deliberate honestly, got some drained on Friday and rechecked once warm and it's still 2-300ml over. It hasn't used any oil beyond the first ~3k miles.

Back it today to be drained again and investigate a vibration at 70mph. I've had nothing but bad luck with this car!

Does the oil smell of fuel?

On the plus side, keep the excess oil you suck out for the next top-up thumbup
