2013 Leon 1.2 - Excessive Oil Consumption

Hi All,

I've had a look at the 'excessive oil consumption' threads that exist but can't see a definitive result...so here goes (and feel free to treat me like a 3 year old - my wife does and it tends to avoid miscommunication!:))

2013 Leon 1.2 TSI - using a lot of oil. I had the car looked at by a specialist who claimed 1 ltr per 600 miles (!don't know what to make of that!) was allowable under the SEAT regs.
But I am getting through ~1lt per 500 miles and seems to be getting worse (monitoring on odometer)
Currently doing ~150 - 200 miles per week for work.
Only obvious-ish cloud of smoke is when the revs are too low for the gear and the engine makes the low down 'clunking' as it tries to cope with my rubbish driving. No smoke on starting, pulling away normally or changing gear (well!)
Had it serviced in Jan and ~600 miles later the 'check oil' light came on. Been topping up since then. They said it 'could be the turbo or the piston rings and I would chop it in for something else asap'
Obviously loathe to do that for the moral reasons but mainly because I really love my Leon and would rather get it fixed than change car.

So....

Any ideas what could be causing it?
What would I need to say to a garage to get it fixed?
Ballpark costs?

Many thanks for any and all advice

Cheers!

Hi,

That's worse than the 'acceptable' limit from VAG/Seat. (which in my book is not acceptable and still be too much)
They quote 0.5L per 1000km/600 miles.

Has it only been doing it since the service? or slowly getting worse?
Have you checked for external leaks?
Check the inlet pipes for excessive oil contamination.
Usual suspects would be PCV, Turbo, valve stem oil seals or Rings.

If it is a new turbo - that shouldn't be too bad/expensive!

Thanks SuperV8,

It was doing it prior to the service and has been for a probably a 18 months. (just didn't drive the car enough to realise at the time)

Sorry for being a dunce but how do I find (let alone check!) the inlet pipes?
And what is the PCV?
Would the vlave stem oil seals or rings be an expensive fix?

Fingers crossed it's a new turbo!

FYI; you have an EA211 engine, you can search for EA211 oil consumption.
PCV is positive crankcase ventilation - or crankcase breather valve.
Valve stem seals shouldn't be too bad. New rings could be expensive.
Do you get any blue exhaust smoke?
A restricted turbo oil return line could also cause excess oil consumption.

Blimey, you know your potatoes! Many thanks again!

No blue smoke that I can see. But there is a noticeable 'puff' as mentioned when applying throttle in a too high gear. E.g: misjudging the ascent of a hill, applying throttle (smoke cloud) and having to change down gear.

Are the things you mentioned something I can take to a garage and say 'this is what it could be?' or would they take offence at that?

Cheers again - super helpful.
