Volkswagen Polo Engine Problems

How is oil mixing with coolant in my 2015 Volkswagen Polo?

Answered by CarsGuide 18 Sep 2020

Despite your extensive efforts to fix this problem, it appears you still have a situation where the coolant and oil are mixing. No oil should be able to mix with the coolant (or vice-versa) and if it is (which is why you’re seeing oil in the coolant tank) then you have a fairly major problem somewhere in the engine. Check the dipstick. Is the oil in the sump milky and opaque? I’m guessing it probably is, and that’s another giveaway that your engine has a major problem.

Perhaps the cylinder head itself is cracked. Maybe the engine has a split bore. Perhaps the light skimming the head received was not enough and it’s still warped. Either way, the oil and coolant are mixing and that’s bad. The fact that the oil and coolant in the bottle are being forced out of that tank suggests combustion pressure is also playing a part, once again signalling a leak between the oil, coolant and combustion areas of the engine.

My new used 2010 Volkswagen Polo already has problems, what should I do?

Answered by CarsGuide 16 Sep 2020

Oil leaks are a pretty common complaint in a second-hand car, but if the car as sold to you with a roadworthy certificate (which it almost certainly should have been) then there’s no excuse for those to reappear within two weeks of you taking ownership. I’m always suspicious of a second-hand car with a sparkling clean engine bay, as it usually means it’s been cleaned up to hide leaks, just as you’re now discovering.

Given that you bought the car from a VW dealership, I’d be having a chat with VW Australia’s customer service and complaints people as there might be something they can do to help in getting the situation sorted out to our satisfaction. On top of that, the dealer who sold you the car has an obligation under the terms of the second-hand car warranty. In WA, that means any second-hand car less than 12 years old (which a 2010 model is) and with fewer than 150,000km travelled, has to carry a one-month warranty on faults like the ones you’ve described. Since these problems were spotted at the two-week mark and pointed out to the dealership at that point, you should be covered.

The bigger issue from your point of view, of course, is that you were told the car had never been crashed when, in fact, it appears that’s not the case. That would seem like a fairly straightforward case of misrepresentation to me, and I’d be having the car professionally inspected (try your local State motoring club) and getting in writing the fact that it’s been crashed and repaired. From there, I reckon you’d have a decent chance of getting your money back and returning the car.

Turbo replacement on a 2014 Volkswagen Polo

Answered by CarsGuide 15 Jun 2018

The car is now out of the 3-year warranty, so if you can’t prove that it did fail within the warranty period you will have trouble mounting a case to be fully compensated. The offer VW has made is a standard one typically used by carmakers.

Why is my 2013 Volkswagen Polo GTi going into limp mode?

Answered by CarsGuide 16 Mar 2018

The lack of performance you’re feeling is when the car goes into ‘limp’ mode because it has detected a problem. Take it to your VW dealer and have them run a diagnostic check on it, which should identify the cause of the problem.

VW keeps leaking coolant

Answered by CarsGuide 26 Feb 2016

If you've had to top-up the coolant twice in four weeks I'd suggest that your problems haven't been fixed and that you should take the car back to whoever supposedly repaired it and have them do the job properly. As for a "safe" option I can't really recommend one, except to say that I would avoid the DSG gearbox. The only "safe" option is to buy another brand, and in that case I would suggest a Japanese brand, such as Mazda, Toyota, Mitsubishi, all of which have a good record of reliability.

Best fuel efficient small sedan?

Answered by CarsGuide 18 Jan 2016

Mazda2, from a classy brand and great against its size and price rivals; Hyundai i20, great value and probably still with some of the factory warranty; Volkswagen Polo, not necessarily to buy but to provide a quality benchmark for the others.

High oil consumption in Polo GTI

Answered by CarsGuide 19 Jun 2015

It's not uncommon to hear of excessive oil consumption on the Polo GTI. The first course of action is to take it to the dealer and have them do another oil consumption test on it. I agree with you, oil consumption of 750 ml per 2000 km is too much. If the dealer can't help go directly to VW and ask head office to intervene. In the meantime we will contact VW and ask for their response.

VW Polo noise

Answered by CarsGuide 17 Nov 2011

You would certainly appear to have cause for grievance. The only thing you can do is to make it perfectly clear to the dealer and VW that you are very unhappy with the product they have sold you. You could also consult the consumer affairs people in WA and put your case to them that you believe the Polo you have been sold is not fit for the purpose for which it was sold.

Under the Australian Consumer Law introduced in January 2011, a consumer can request a refund or a replacement for persistent problems if the car doesn’t do the job it’s supposed to do.

VW Polo catalytic converter

Answered by CarsGuide 6 Oct 2011

Unless you can show that the cat converter fitted in 2007 was in some way faulty I would think you would have to pay the full cost of a replacement now. The Polo is out of warranty, so I would suggest you consult an independent VW specialist who would likely be able to supply a cheaper converter.

Misfiring Polo upon idle

Answered by CarsGuide 30 Jun 2011

Consult a reputable VW specialist to get an independent opinion on the misfire, what it is and whether it is normal. Armed with that advice go back to the dealer and VW and ask for a meeting to discuss/  resolve the issue in the hope of finding a way forward. If that fails then go to the consumer affairs people in your state.
