Hi, I own MK3 VRS TSI. It is currently on 32,000 miles and has recently been remapped. 

 

Within in the last month or so I have realized that it is using an unusual amount of oil (registering as full on the dip stick lasts about 350 miles.) 

 

There is no smoke coming out of the back, nor is there any obvious leak. 

 

I was thinking turbo seals?

 

Can anyone think of any other possible causes for this, that may be a cheaper fix?

 

I appreciate any help received. 

If it was turbo seals; I imagine you'd see a lot of smoke out of the exhaust when you rev it.

@BenMiller who mapped it?

 

Might be worth a chat with them?  Nothing to lose and they may have seen this before / be able to help if they are reputable.  

 

Good luck!

Have you been checking oil properly? There is a difference between hot and cold engine up to 30%. 

 

I suggest you check 10 minutes after oil was on its working temperature, 90+, then come back to us with your findings. Maybe oil consumption isn't really that bad ? Pretty fresh car you have to have severe oil consumption.

Checked for drips?  I was losing some oil for a while, turned out to be a loose oil filter. Easy fix.

 

It was mapped by Quantum, I think i'll contact the mapper, hadn't thought of that!

 

Have been checking the oil as said above. 

 

Can't see any drips or obviously leaks, currently have the car parked over a large piece of cardboard. saying this, would be nice to find out it is a leak!

missed information.

That is pretty bad. Looks my turbo has failed after 40k well maintained and treated miles. Seems VAG are heading down the reliability tables rapidly if you research it. Especially the VW/Skoda sides. Mine isn't burning oil though. It doesn't need a top up between 10k services, drops about half way down dipstick range in that time. It was properly run in and that makes a difference to future oil consumption, used a litre in first couple of k then reduced to virtually nil. Ragged cars from new usually like supping their oil for life which will also be shorter. 

 

If that oil was getting past turbo seals it will already have wrecked the cat. You said its been mapped. If the map has messed with the throttle valve it can create too much vacuum in the inlet sucking oil past rings and valve guides.  This happened with the Nissan/Renault 1.2 turbo engine, I had one and it drank oil, could empty the sump in 2k! The fix from Renault/Nissan was a map ECU upgrade to limit inlet vacuum on the overrun and it worked, I wanted a new engine and was adamant it wasn't going to work. It bloody well did though (to my disappointment!) needed approx a 1lt  top up once in 12.5 k after that. So maybe speak to your tuning place. 

Mines needs topped up every month or so, has done since I bought it in February.

 

No running issues, no leaks, no oil coming out the exhaust. I've spoken to an Audi technician who claims it's normal for some VAG cars to be using 1 litre every 1000 miles, which is enough to take the dipstick to the MIN level. It's not common, but it's something he's seen enough to be aware that it's happening to people.

 

I'd definitely get it checked out yourself though.

There's a fault. My MKII TFSI drank oil. My mapped TSI hasn't needed a drop in 4 years between Services every year or 10K miles.

My Oct 2 also, there's a thread somewhere.  I returned it to the garage for a full refund after 6 weeks.  At the rate it went through the stuff it was a case of nearly a litre every time I filled up with petrol

The MkII TFSI didn't have a problem, drinking oil in comparison with my MkIII, actually means about 100 ml every 500-600 miles.  It seems that it was meant to use oil, fantastic engine and car. Initially worrying about a blown head gasket, I realised, after I got used to it , that every winter loads of mayo appeared in the oil filler cap after commuting  daily 10  miles each way at 50-60 Mph on A roads. This was due to condensation. No mayo after long runs i.e. If the engine stayed hot.  No such issues with the TSI. 

Comparing his car with a different generations with completely different engines isn't really helping the OP.  Not normal for EA888 Gen-3 to lose much oil. Issue should be detected and resolved. 

 

I've only had to top up a couple of times, each time about 500ml, but I'd say that wasn't that bad over the time that I've had the car and I'd expect to do it over the period of 30 months that its been with me. 

Thank you, for the advice. 

 

It has now developed another issue. A week or so ago it began to miss fire, cylinder 2 was the issue. Replace spark plug and coil, issue was resolved. 

 

Driving home last night and it begins to misfire again, cylinder 2. 

 

Might be unrelated but worth mentioning. contacted the tuner and he will have a look this week. 

Possibly oil getting onto the spark plug ? It all seems to suggest a problem

First port of call is a compression test, even better a proper leak-down test. That will show up problems with the bores or piston rings. Condition of plugs will tell you some more. Turbo failures can give smoke on either throttle or overrun depending where the problem is but not always

 

Oh and check for black puddles under the car, or rainbows where you park when it rains. Sometimes it is the simple things.

 

As said above oil consumption is not a common problem on the EA888 gen3, however things do fail.

 

Level on mine does not move between oil services, however I did take a bit of care running it in when new.

Really?  I responded to the OP and said immediately there is probably a fault with it, as in comparison with the TFSI there should be virtually no oil usage, which I thought would be helpful. I then exchanged a post with another MKII owner again pointing out there are no issues with the EA888. Where's the problem? Almost every post on these forums seems to attract criticism, quite often incorrect or deliberate trolling. 

Replaced the spark plug, drove 2 miles. Parked up, pulled spark plug, covered in oil. 

 

Afriad that I have come to the conclusion that it is piston rings. 

 

Gutted.

Unlucky, how many miles has the engine done? Presumably correct oil and within service schedules? 

@BenMiller   Who did the remap? 

Have you had the car from new, and if not for how many miles before getting it remapped?

 

EDIT. 

Sorry i see now it is a 'Quantum' map.   So who did it?

Edited 3 January, 20197 yr by Skoffski

The engine is on 32,000. 

 

correct oil and serviced at correct intervals. 

I didn't own it from new, i purchased the car from Skoda with roughly 2500 miles on it. 

 

It was on 29000 when i had it remapped. 

 

It was taken to Qauntim in maidenhead to get mapped. 

Maybe turbo is gone due to poor mapping so leaking oil in air intake? Not many scenarios can lead to oil consumption and be related to remapping. 

 

I hope you will resolve it quickly, without much expenses.

Could be a few things, like I say, compression test is only way to narrow it down. At least you will know where not to go looking. Was it one plug or all of them covered in oil?

 

IS20s have obviously failed in the early days mainly stateside, but that is not a failure I have heard of before.

Just one.
