Yeti burning oil. Should pistons and rods be replaced as well as piston rings?

It doesn't do it while idling, which makes me think not (?) Accelerating and turning sets it off, and it stops after 10 mins or so of driving.

In the 'old days' a blip of the throttle or turning the wheel when stationary would provoke it, but they were the old V belts.

Now after 400km since the engine overhaul it's showing a message that it needs a service... but it isn't due a service. The local Skoda experts (not the people who did the work) suspect it's bad oil quality caused by dirt after the rebuild setting off a quality sensor, which makes sense. So i really hope that's the issue as a simple oil change will do the trick.

 

I really long for the day when I don't have to keep taking it in for work... but maybe that will never happen... it's making a chirping noise on cold days. I really want to trade it in for something that's under warranty, but I don't think we can justify the expense given how little we actually use the car. When we need it we really need it though.

 

Well, I hope none of Skoda team told you it has quality sensor for oil... That one mounted on bottom of sump is only combined oil level sensor and thermal sensor. When the car is set on variable interval, according oil temperature, driving style compared to maps stored in ECU then instrument cluster calculate when to send car to service for new oil. So do not know how many km you done but I think that garage which changed the pistons and oil did not reseted via diagnostic the interval. Or might by possible via MAXIDot MFA if you got it. If you have done at least 5kkm, let change the oil, if not, just let erase the message and wait for better mileage.

 

Chirping noise, that is very wide explanation, TSI sounds normaly as "sewing machine", especialy when you notice that only while driving smothly/fluently on cold days, not on idle, acceleration etc. When engine is warm, do you notice that too? Have you noticed that before the water pump change too?

The 1.8TSI engine is chain driven and the water pump & housing is located on the front of the block, driven via a shaft from the timing chain on a small auxiliary belt. 

Cheers James; my point was actually about an inappropriate geographic localisation of prices rather than about replacing the cam drive.

Yes, they did. Two of them. And the garage doing the work (supposedly specialised in Skoda servicing) concurred that this is what has happened. I won't be paying for the oil change, so OK, they can do it.

I don't know what that is...

It goes away when the engine is warm. Yes, I noticed it before the water pump change, and mentioned it to the mechanic. He thought the change (done for coolant leakage) might fix it. It actually seemed worse after the change, but now it seems to have gone away. Thing is we've had warm weather though, and this seems to be a cold weather thing.

Well, they do speak rubish ... See what the combined sensor G266 does in files below, original file in French, machine translation into English, page 32. Can be ordered in English too from

OK, when it´s free, let them to change it, and you can ask them to swap coding at instrument cluster onto fixed interval 15kkm/1year but keep sensor on so it still works. That will mean you will be on QG2 instead of current QG1 interval.

 

Sorry to confuse you, MFA is from German, I meant display type MAXIDOT in instrument cluster, better one than regular Segment display

Regarding the noise, when it was there before new pump, I guess must be something else. So you recon it is surely from engine space?

You have to find someone reliable to drive it with you so you can notice him the sound, hope still any Skoda team member at any dealership in Sweden knows how to help not for much bucks ...

Thanks so much for the detailed advice! This is quite mysterious about the oil quality thing. From googling it seems a lot of people are confused about whether or not there are oil quality sensors in these engines.

 

The sound has gone for now. It came from the front right, from the driver's perspective. I'm not 100% sure it's from the engine space, it could have been brake pads on that side. I will try to troubleshoot it more on the next cold damp day when I expect it to return. 

[YetiSweden]

Well, one more update: total engine failure!

 

The garage dong the engine repairs messed up somehow so that the engine took in air, failed, and has had to have major repairs again, this time on the top of the engine. It is now finally repaired properly by the Skoda garage, with the insurance company from the previous garage footing the bill for the botched work.

 

But now, finally, hopefully, it's all over and we have a decent car again!

[rayx]

Oh, what a sad story, I believe good ending for you. Did you notice oil consumption issue again before failure or did the engine stopped suddenly without any notice?

For the dealer who sold you the car, it is double paid rework experience, team at first garage was surely not competent to fix such complicated engine. Hope for you all the bad is gone now and you have your Yeti with troubles engine from Skoda garage.

[rayx]

Sorry, meant troubleless engine of course, wish you only the best with Yeti

[andreasw]

How did this play out in the end? Interested to hear since I too love in northern Sweden and driving a Skoda! 

[BrettJ]

If love to hear how things are, ask these years later? I have troubles with my VSR, high oil consumption. Surely a similar issue

 

[Ootohere]

@BrettJ  Similar as in they use oil,

different in that you have a TDI & not a Euro 5 1.8 or 2.0 TSI. 

[BrettJ]

So similar in that they did the same thing to the oil rings. Specified them too small, so you need to change pistons and rods as well?

 

It is now using 1 litre oil for 600km, typically. It is at its worst on the highway, and marginally better on small roads.

Not sure if there is a fix but it's more related to your engine than this thread
