Polo GTI High Oil Usage - Discussion Thread

[kawabanga]

It seems madness that you have had two defective engines.

In Italy, on some GTIs and some A1s, as well as in England, they are not even doing the already scheduled engine's change, waiting for the modification to the oil separation system...

Give it a lot of running time. See if anything changes. Especially on your car Karly. It seems madness that you have had two defective engines.

Technically only one defective engine with a failed engine rebuild... I'm not sure also if they honed the cylinders when replacing the rings? Would think they would have but didn't ask. So far so good still on this one and hoping to take it out of town over the long weekend... unfortunately been too busy at work to do much and my daily commute is only 15 minutes but I did take it for a good drive for the first 200km. The previous engine didn't do any inner city stop start driving and it made no difference, I think it was also just a bad engine as my oil consumption issues didn't start until 7,000km I think it was?

I'm not the only one though where the new piston rings made no difference.. they were doing another gti after mine at the dealership (I nicked their engine as theirs was booked in the month after mine and my oil usage was too excessive!). I have a feeling the dealer was getting sick of me coming so often for top ups haha.

Did you change type of use (city, start&stop, short trips) after 7.000Km with the previous engine?

We also had a lot of cases where the same engine had completely different behaviour about using oil, depending on the type of route done.
And the behaviuor was not one way: after a period of only-city and great oil consumption, they had again normal consumption going again mainly on highways or country roads...

Anyway, this could just not be a excuse for VW, except writing on the GTI's specifications "Not for city use"...

If you drove a Polo GTI in Australia and stuck to the road rules the engine would be doing a far lot less work than a European based GTI would do anyways. Average speed on European motorways is 120/130 while over here we are lucky to get to 110. So you might be correct....The engine might not be getting the work out that it needs in Australian driving conditions.....I don't get it though...VW should never of designed the Polo GTI engine on pretty much racing standards......Driving around living the dream should be the first priority in any road car.

[kawabanga]

Yep and in Germany they don't even have limitations on some highways...

Some Italian GTI users found a certain improvements in oil consumption changing driving style in the city: no more D, only manual, no foot on the floor at low revs and never wait for the engine to warm up before reaching 2.000/3.000rpm, but starting immediately at those revs, of course if traffic condition permit it...
I'm not sure if those suggestions are good [I drive only country roads, no lights, Italian limits (read it as "no-rules-but-only-suggestions" ) and 0.7liter/10.000Kms], but more than one user said they had benefits doing this...

[Acko1991]

The engines are defective. Plain and simple....but if i was VW i would be asking there engine building department what is going on....Obviously there is a quality checking system in place. Engines with incorrect measurement tolerances shouldn't make it into the vehicles.

[Karly101]

I am wondering if the lazy gearbox has anything to do with it? The engine is never really worked around town... it just wants to get up to the highest gear possible and just doesn't go through a whole range of revs...personally I can't stand it and always drive in manual or sport mode...just as I got the new engine my work has changed to be a short commute in stop start traffic (the worst kind) .. not great for running in a new engine but this wasn't my plan! I miss my old commute which involved hills, freeway driving, varied speed limits and not much traffic. But seriously.. for a new car to be this fussy/fragile about run in procedure??

[Acko1991]

Its not good Karly. Just make sure you keep all the evidence. Maybe you should have a chat with the fair trade ombudsmen or some legal advice if you keep having issues with the car. Its not satisfying your needs or your requirements because of an engine which doesn't like to play.

My 77TSI manual loves to be in the lowest gear possible...It always tells me to change because of fuel consumption reasons which it is one of its major design targets. I am guessing the computer in the DSG is playing a similar game.

fun fun. Even go and whistle blow your story to the newspapers......That seems to upset car companies and make them do something.

Agree!

So after the dealer tellin me the piston rings will be replaced - two weeks ago after waiting 3 weeks for them to tell me that! - Friday they call me saying they're replacing the whole engine with a new one and it'll take TWO more weeks. least getting new engine... But will it be the updated engine? The one where they've fixed the oil issues that I had etc that the new Polo GTI's will get from mid this year?

[cyborgcuprajq]

If they fit another engine will be a overhauled one. Not brand new made from scratch.

[kawabanga]

Even if my GTI used a little amount of oil until now (0.7l per 10.000Km), I checked air intake pipe to see if the oil separator could actually be "the problem" of TSI engine...

Look at the pics: the problem is that I found oil out of the separator and just where the separator goes into the main intake pipe (pic#3).
So the separator doesn't work properly!

Gav, let me know your ideas...
People who have high oil consumption should check if they found a larger amount of oil there...

[Acko1991]

I don't think that would effect it as much as the piston rings and the cylinder clearance.

[gavs]

Driving at low speeds, lazy gearboxes, loading a cold engine? Really guys, there is only one logical and admitted issue and that is poor manufacturing tolerances. The blowby is obviously partly to blame also due to the new oil separator being put in the CTHE motor but as I have said before, don't expect any admission of guilt or any real fix, otherwise it would have been done. Still not convinced that the new motor will be rid of these problems either...

Can you explain more?
