Hello there Sajeev, hope all is well with you. I have an issue with a 2010 Audi A4; my boyfriend bought this car from a dealership (used). However, he didn’t even have the car six months before realizing there was a piston ring problem — he would have to top up the oil when driving the car. We informed the dealership about it, but they gave us the run-around and did not fix the problem.

The car is financed so he’s still paying for it and has about $9,000 left. The car is completely dead at this point; we know about the cost to fix the car but we’re stuck on what to do with the car. Working to pay to fix the car is a lot within itself and we can’t sell it because we’re still paying for it.

We also contacted Audi but they didn’t help us, really. Any solution to this problem? (Read More…)

Hi Sajeev,

You are my go-to guy for in-depth automotive knowledge. (Wow! Honored. – SM)

My brother has been having a heck of a time with his 2012 Mazda3 Skyactiv. It’s got about 70k miles on it, and in the past 2 years it’s been in and out of the shop. It started with high engine oil consumption (more than a quart per 3k miles, and going up to this day). Then the ignition coils needed to be replaced. Then the MAF and oxygen sensors needed to be replaced. Right after those were fixed, he had to take it back to the shop because there is now a misfire in one of the cylinders.

What’s going on here? My only guesses are worn piston rings causing engine oil to run into the combustion chamber (then down the exhaust and ruining the O2 sensor), or malfunctioning PCV, a broken EGR system, intake valves with a lot of carbon deposits, or simply “bad luck” with this car.

Hope you are able to shed some light on this mystery. Thanks! (Read More…)

Sajeev, this is a 2010 Audi A4 Avant that is in like-new COSMETIC condition. It was purchased over my wife’s strong objection, as none of our four prior Audis has made it past 80,000 miles without suffering a complete and total meltdown. This one suffered an oil consumption meltdown at 65,000 and required a new set of pistons and rings – paid for by Audi! It now has 99,378 miles on it and a Blue Book trade value of $6,000.

The other day the check engine light came on. I correctly internet diagnosed a loose bypass valve on the turbocharger and was ready to write a $2,200 check to replace it. Not so fast said the Audi man! To get the light off it requires (1) a new turbo, (2) a new PCV valve, (3) a new cooling fan, (4) and some other new item at the back of the engine. On top of the typical A4 oil consumption and turbo failure issues, the Audi man says it has the third typical A4 issue – carbon valve build-up, which causes it to chug and spew vast amounts of smoke on startup periodically. Finally, it needs all new front end bushings. This is set to cost a grand total of about $6,000. (Read More…)

Those hoping to make it big on oil commodities would do well to bet against the bulls on parade, as China won’t be around to keep prices afloat this time.

I have been on your site for a couple years now and don’t remember ever seeing this topic. Our issue is we have a 2007 Suburban with a 5.3 AFM (Active fuel management) motor that was burning 1 quart of oil per 600 miles. (Read More…)
