Volkswagen Polo Engine Problems

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.

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.

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.

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.

Yes, it does sound like the PCV valve is acting up. Replacing it should fix the problem.

That's a little premature given the company has agreed to replace the engine, which they claim is the source of the problem. While I can understand your frustration, I would let them rectify the problem first.

It’s breaking down under load, i.e., acceleration, so check the ignition system, that’s coils, leads and plugs, and make sure the fuel pressure is correct.
