Polo GTI High Oil Usage - Discussion Thread

[gavs]

If you are referring to me, rest assured you are mistaken.

I am actually happy for all of you without oil consumption issues...

No, really!

Grrrrrr....

Nah mate, I was meaning more of a blanket statement for all those with consumption issues.
After 6000kms of dedicated manual and sport only driving I saw a drop of 1.5mm on the dipstick.

Lucas, I agree with your observation but if you follow any VAG turbo car, they all puff black smoke under decent throttle application. The GTI motor runs pretty rich down low but dangerously leans out in the top of the rev range so it's no surprise you're only seeing it puffing as the car takes off. Personally, I'd be very wary of running this motor to redline often without a tune. As usual though, VAG would rather keep replacing engines and components under warranty rather than admit they stuffed up.

After a change to FUCHS at my 15k service have now completed 21k and has only needed 200ml top up.

Still have soot on the back of the car but am happy that it is not using any oil.

Hi there...!

Probably you can find something similar also in Australia, here a car preparer (bobracing) is now able to modify DSG7 software: not only elimination of kick down, launch control, reduced shifting time, etc., but also D's behaviour, overall changing gear's revs.
This will probably be useful for oil consumption problems for who still want to use automatic...

I don't have it, but some guys are now testing this new modification: in the software programming phase you can choose at how many rpm it shift gear...
Probably half way from the current D and S could be perfect...

so after numerous oil consumption tests. VW maybe doing an engine rebuild for me. Just wondering what should I ask them to do in additon to just rebuilding the engine. Should I ask for new piston rings, etc??? Also would a rebuilt engine need to be run in like its a new car ? And finally does a rebuilt engine warrant the odometer to be reset to 0 ? or that only for new engines? Thanks guys will update you as well on how this case goes.

Unless you're prepared to pay for it yourself, the dealer isn't likely to do anything beyond what they've diagnosed is wrong, so you can request it, but isn't likely to happen as warranty.

RE running it in, ask the dealership, but its something that opinions vary from baby it to drive it like you stole. I'm towards the later, don't flog it, but don't nurse it at low revs, engines are designed to rev so do that. I like the idea of putting it under load when new to bed everything in, so a nice mountain run which loads up the engine, also keeps the revs varying. I accept the logic in this approach.

The odometer will not be reset.

Good luck, hope it's all smiles once sorted.

Thanks to this thread I've decided to join after months of lurking around here... As far as I know I probably have the worst luck for oil consumption in NZ :|

I'm on my 3rd test now, had two top ups from the dealer in the last 2000ks with one done myself the very first time I had the oil warning light on... and was told they had used 700mls in top ups? (to my knowledge extends to knowing that dipstick A to C is about circa 1L? Correct me if I'm wrong)... Those "tests" the car didn't even get to 1000km before needing to top up

Perhaps dealer negligence in issue but for both tests nothing was done to seal the engine cover to prevent voiding the test up until the 3rd time (this week) when supposedly the breather pipe mod was done (with no available evidence to suggest nor paperwork) when the "HOLD" sticker was used with the test reference number.

The Detroit wheels were kerbed extensively on one side when I collected the car, there was a crack on my headlight, a scratch on the drivers door... luckily for me I hadn't driven the car off yet and it was still at reception.

Back in the stealership for the car, was reassured that they have a strong policy on damaged cars on premises etc. And luckily the car was also due in for new clutch packs that same week...

Not bad for a 2nd post huh?

I thought it was time to contribute my experience on my April 2013 (built Dec 2012) CTHE-engined Polo GTI. I'm doing very low mileage at the moment, almost exclusively gentle driving in D in urban traffic. In the 7 months since I got the car, I have completed only 3,100KMs. The yellow "check oil" light came on at 1,600KMs and was topped up for free. Now, with 3,100KMs on the clock I can see that the oil level is again only just registering on the very bottom of the dipstick, well below the hatched area and I'm anticipating the light coming on again any day. I washed the car today and it's pretty sooty round the back.

So, that looks like 2L of oil in 3,000KMs. I've got a good relationship with my VW dealer in Christchurch and will get a consumption test done. Can someone remind me, what's the officially acceptable level of consumption (assuming there is such a thing), below which I can insist on something being done?

Thanks,

Simon

The manual says something about that... I can't remember but yours seems a bit borderline tbh...

I've got a good relationship with the folks here at Giltrap but lucks just not with me...

1L/2000km, but check your own manual to verify.

[mmmRacer]

Using more then 1L/1000km after the breather mod is a engine change.

[scobb]

I assumed that the breather mod was already incorporated into the design of the CTHE engine, as one of the improvements over the CAVE engine. Is the not the case?

CTHE contained many of the supposed "fixes" that were implemented in the CAVE consumption campaigns as well as a different oil separator and internals.

As I have said before, until they fix the tolerancing issues with the manufacturing and accept the fact that they have screwed up on multiple occasions in their pursuit for fuel efficiency, VW cannot fix this problem. 'The cars are meant to be driven hard so they don't burn oil, use thicker oil, it's not an auto so you can't drive it like one even though that is how it's sold...'

All common comments from dealership service departments because they really have no ability to fix the problems because vw won't let them.

I'm pretty sure "pulling apart the engine" doesn't count as engine change...

Only time will tell... Also asked about the number of issues re oil consumption in Auckland and was told only 3 vehicles

I was told they can't warrant anything out such as the case with breather mod and engine rebuild without contacting with VW Germany because of warranty costing i.e to be paid to do the warranty repair work - is that the case?

Wrong. VGA (Volkswagen Group Australia) makes the reimbursement payments to the dealerships, it's their call, not VAG. The computer systems link back to Wolfsburg yes, but it's the call of VGA to fix the car under warranty.
