Hello gents! 

I also replaced the head cover last year and no improvement in oil consumption. It's same as before....so need to go deeper. 

Cheers! 

Is your compression fine? If that's the case, than it's almost certainly the valve stem seals. The piston rings and valve stem seals are the only components left that could cause this. 

 

Also, changing the PCV diaphragm made no improvement. I'm almost certain it's the pistons head or pistons rings.

It seems to me that all fingers point to pistons/piston rings.....unfortunately 

Yes. That is my guess too regarding my car. I think there is WAY too much blowby, that's why there is oil in the pcv pipe that leads to the intake. 

 

I will probably be opening up the engine sometime in the spring for a repair. 

@BogdanBHow much you looking at for a repair if it is the pistons/piston rings?

 

A service shop asked for a starting price of around 1200Euros which is  mostly the workmanship for opening up the engine(going up, depending on what's found there. ).  Going to weight my options though.

I am very distrustful of service shops. Most of them don't even use torque wrenches and so on.

All the repairs that I've done on my current and previous car, have been in my garrage with my father

Did you replace it for a brand new one?

 

I've took a look at the PCV valve in the cover I've got off ebay, apparently the car had about 60k km on the clock. The membrane is deformed a little bit, but not completely. I am wondering if there's maybe something in the actual plastic that we are missing, apart from the membrane itself... (bad design?).

Yes, brand new. Design was slightly different so looks like it's a revised version.... On some cars there were problems with old head cover design. 

Changed the rocker cover, no more oil in crankcase breather hose. Also noticed some oil leak on oil housing, I am wondering if that's not the oil cooler leaking (I also noticed some coolant level drop). Gave it a clean but will monitor and most likely replace.

 

@BogdanB

 

You've got some oil temperature issues, did you check the oil cooler for leaks?

What's your oil temperature range? By my understanding, the oil should usually be at least 100*C. I've read that 110-125 is the desired range.

 

 

Also, where is this said cooler located?

 

L.E. : This is also from the owner's manual, which confirms my thoughts:

 

Quote

If the engine oil temperature is in the range 80-110 °C, the engine operating temperature is reached.

If the oil temperature is lower than 80 °C or above 110 °C, avoid high engine revs, full throttle and high engine loads.

It usually never goes above 100 but sits below that temperature (and above 80).

 

It's integrated with oil filter housing, the radiator is on the top. Will update in couple weeks.

Hello,

Any news about this topic ?

 

I just received my Scout 2015, 2.0 tdi, 135kw ( 175k km)  from service ; they did the oil weight and discovered, that oil consumption in 300km was 0,46 litres. 

Im a little bit lost couse they dont know what is making engine to lose oil. There is no leak, no oil spots. And now Im a little bit confused

I went back to service becouse oil light turn on when i made 1500 km, now they said that car consumpted 0,46l in 300 km ( Fu*k me If i know how is that possible 😞 )...

 

I bought car 2 months ago from Skoda DE; all service was on spot ( 30k km ). 

 

Now our service in SLO changed the oil (again ) and oil filter and said, that i need to call them when oil light turns on again

 

Shame, cause I went from Opel to scout in good faith ( and i need 4x4 ), but now... 

 

skoda..

@Zigaka  Welcome to the forum.

 

Did you get a copy of the official Oil Consumption Test & was the oil shown as weighing 856/ 857 grams a litre? 

 

Here this Technician seemed to think a litre is 1,000 grams.

 

Here the member got a new engine since the official test was total rubbish and actually 0.3 litres in 1,000 km was not acceptable oil use. 

(Bottom 2 was the old way of an oil consumption test.)

If you made 1500km before the light came on, then it's certainly not 0.46l / 300 km . More like 1L / 1500km since high to low is about 1L in this engine.

I didnt get a copy of test, since the service told me that all costs are on them. 

But they were really honest about the fault, told me that this isnt normal for this engine, also said that they had only one Vrs with 135 kw engine which had oil problem. But reason was in abnormal abusive driving, which is not the reason in my case.

 

Thinking on loud - is there any possible reason that the problem is, that i live uphill; when i start the car, i need to drive approximately 20 m on road which is on 26 decrease up ( well, thats the reason for 4x4 ). I allways start the car, leave it for 5 min ( in this time the windshield is defrosted ( i have windshield defrosting ), and car is a little bit wormer for the kids ). But i allways put it in manual first gear, no aggresive driving uphill. If this is the case.. I dont want to think that this is the case ( than its "Scout" really just for the beauty ) .

 

 

@BogdanB, possible, yes. I only pour it to the half of the stick. Thanks for pointing that out; i forgot to tell the dealer that i was pouring oil to the half of the stick and not all the way to the MAX... 

Hello to all, 
I too have a 2017 octavia MKIII in 184hp with a 220hp reprog, the oil consumption is also exessive approx 1L/ 1500 km, especially when I drive on the motorway. it has 77000 km, and was already consuming oil before the reprogramming.

hello, I also have a modified engine for 100k km and the oil consumption is almost the same. I have 1l at 5-6k km.

 

Now I was talking to a friend and he solved this problem by exchanging the pistons, which have a third ring higher. The original is 2mm and he put a piston with a 3mm third ring.

He is now driving 5 km from the repair and it didn't take a drop of oil.

 

The bonus is better engine sound and even higher performance.

Any progress from anybody?

 

I have a VRs, from 2017, and with about 140k km.

 

Mine is using about 1 litre of oil for 800km driven, if on the highway, with cruising around 130kmh. Regenerating the dpf also at around 800km.

 

If in normal daily use, it is around 1200km+ for the same oil consumption. Harder to say about the dpf.

 

No smoke I am aware of, but then it has a dpf, so shouldn't smoke.

 

I can only think the turbo is the culprit. Why would it be anything else. I guess I'll have to bite the bullet and just get it to a dealer.

 

I notice a few in here were in Slovenia, as I am. Any dealer experienced in this issue?

 

 

I was also thinking about checking the turbo. Mine also behaves exactly as you describe. Around 800km on highway or more in daily use.

I highly doubt your DPF is regenerating at such high intervals. 

 

Keep us posted if you check the turbo.

Edited 12 May, 20224 yr by BogdanB

i bought almoast 2 years ago a vrs, 2015, cupa E5, from Germany, 200.000 km, full service history.

never had a vag car before, only renault gt's and rs's

first problem that i've noticed was the car was regenerating from 80 to 30 km done.

After i've fixed that, i'ved noticed the oil consumption. 

The problem was that the car was not  smoking at all and was looking healty and there were no signs of illnes of the engine. only oil consumption (nobody could guess that the car had a problem at all.  you could noticed that, only if you run the car a lot and the oil light was warning you. the car ran perfect!)

i had 1L/2500 km oil consumption. in 1,5 years, i've changed 2 turbocharger's, the rocket cover pcv, injector seals, egr +cooler,  the valve stems, washed 2 times the dpf, timing belt kit - 3 times, lots of sensors (egt, landa), but nothing worked.

at that moment, the car was regenerating around 200 km in town and around 400 outside.

i've decided to open the engine and see what was going on (first i tought the piston rings were the problem):

- cilinder head deformated, 

- engine block deformated and scratched

- pistons scratched

- piston rings full of slime

- exhaust valves,  some of them had play 

i had 3 options:

1 new engine (too expensive)

2 full engine rebuild (nobody trustfull)

3 used engine

i chose to search for a used engine, and after 2 months i've foud one from a back crashed audi q3, DGCA that was 60000 miles. i had full service history of the car and the car vin was coresponding to the engine code. so, was real!

i bought the complete engine with injectors, fuel rail, whater cooler, egr.....

because the dgca have variable camshaft timing i've swaped it with mine, also the rocket cover

another incompatibility was on the intake part, at the whater cooler where the DGCA have another egr that is comunicating with the cylinder head, and my E5 doesent have, so i've mounted my whater cooler.

in conclusion after the swap there is no oil consumption, and the regenerations are the same

i think the problems were from bad exploitation, 30000km oil change intervals and the engines heat management (this engine runs at verry high temperatures - egt - 900 degrees celsius in full throttle)

All parts that i bought in time were geniue vw and after i've done a total amount spent on, the car, on parts and labour, at the moment + 6000 Euro i could've buy a 2022 new vrs, tsi car!

in conclusion don't do like me and if you sell them tell the buyers that the car have oil consumption problem.

i think that this engine doesent consumes oil at all if the engine is't abused and the oil change is made at maxim 10000 km, with good oil, but who buyes a vrs to run low?

 

  

.........................................

Hmmm. Thanks Modro. That seems to be the first conclusive diagnosis in this thread. It does make me think I'd be better selling it and getting a non Vag vehicle, or just investigate the oil usage a lot closer on the next one I buy.

In the current market, I think repairing it is better. Cars are 20% more expensive nowadays. 

I am not convinced if that at all. I looked over the last few days, and prices seemed similar for the same vehicle.

 

But I also wanted to swap to the 4x4 version anyway, so I have another good reason to change. In fact, I was after a 4x4 in the first place, and couldn't find one in Covid. Now there are plenty for sale. 😁

Hello I also have a VRS MY2014 with high oil consumption...  On highways it burns from max to warning on dash in about 400-500km

I bought the car in 2018 with 147k km and now I have 207k km.  The oil consumptions is rising over the years.  I had a  oil leak between the head and the modular part that houses the cams.  The oil fill cap is always wet from oil and now I think the seal on the belt side of the crankshaft started to leak.  

Doea anyone else have this problem.  I'm thinking piston rings. 

I made a compression test and got valuea that are on the low side of the ok parameters

Piston 1 is 26bar

Piston 2 is 25bar

Piston 3 is 24bar

Piston 4 is 25bar

The haynes manual says the range should be 25-31bar and the engine at least 30 degrees celsious

And the maximum difference of 5bar

Absolute minimum is 19 bar

The car does not smoke but the DPF git clogged.  I took it out and cleaned it with a solution if water and HCL. Then rinsed it with a high flow of water.  The celan was great and the regens that we happening all the time are now 600km appart.  But the filter will get clogged up again if I don't fix the oil consumption issue
