Blue Smoke
Blue smoke is the most blatant and distinct indicator that your Q5 is burning oil. Oil has entered the combustion chamber, as indicated by the presence of blue smoke.
The gasoline is then burned with it, giving the exhaust a blue hue. If your exhaust is terrible enough, it will resemble a two-stroke engine more. Find out more about blue exhaust smoke below. The presence of blue smoke indicates that your Q5 is burning oil.
Low Oil Level
You have undoubtedly arrived at this page for this purpose. However, burning oil is not always indicated by a low oil level. It can be escaping from the engine.
Whether you always park your Q5 in the same spot, check below to see if the engine is wet. This might be a sign that the oil is leaving the engine through the seals rather than the combustion chamber.
Oil on Spark Plugs
Oil may get onto the spark plugs if it manages to get past the valve seals. Your Q5 is likely to start misfiring and running worse when this occurs since the spark plug won’t be able to provide a clean spark. Discover more about identifying oil on your spark plugs here.
Smell
Oil burning emits a distinct odor. Even though exhaust is never pleasant to smell, it always has a distinct charred fragrance. Typically, you’ll notice blue exhaust smoke before you smell burned oil.
How can I put a halt to my Audi’s oil burning?
Burning through oil too quickly damages your engine and eventually leads to it failing entirely, even if your car is not overheated.
We do not advise attempting to DIY this repair as it is not a straightforward one. It’s recommended to leave it to an Audi mechanic or an Audi shop because you’ll need to remedy both the problem’s cause and whatever damage it caused.
There are three solutions to this problem:
- changing the crank case and installing the most recent version of engine management software Although it sometimes seems to lessen the issue, it doesn’t seem to be a long-term fix. We do not suggest the repair due to its unreliability.
- replacing the pistons, piston rings, and con rods after removing the engine and dismantling it down to the cylinders. This will solve the issue entirely if the engine has no additional damage.
- The only option if the engine has been damaged is to install a brand-new or high-quality used engine. This is a surefire technique to resolve the problem for good.
The Audi Q5 uses up oil, right?
The 2015 Audi Q5 was highly lauded by the reviewers at U.S. News for its accurate and snappy handling as well as its large list of standard amenities. The Audi Q5 has long been considered as a handsome and enjoyable SUV with a calm interior. The 2015 Q5 received strong accolades for its overall performance, interior quality, and safety ratings, earning a score of 7.6 out of 10 on the U.S. News scorecard.
Due to its low reliability rating and expensive cost of ownership, it ultimately came in at number 10 on the list of 2015 Luxury Compact SUVs and number 48 on the list of Used Compact SUVs around $25,000.
Consumer Reports noticed that the 2.0-liter turbocharged four-cylinder or the 3.0-liter supercharged V6 engines in the 2010 to 2015 Audi Q5s prematurely burn oil. Audi did issue a diagnostic to identify the issue, but Consumer Reports concluded that it would be best to simply choose a another car.
Is oil burning on an Audi typical?
The assertion that oil consumption is a typical aspect of a car’s operation is one that Audi, BMW, and Subaru steadfastly uphold. Every 1,000 to 1,200 miles, Subaru deems a quart of fuel burned to be acceptable. According to the requirements for some Audi and BMW vehicles, a quart of fuel should be burnt every 600 to 700 miles.
A driver may need to add up to 7 to 9 quarts of oil between oil changes if they must add a quart of oil once a month. Because automakers more frequently need synthetic oils, which can cost upwards of $9 per quart in addition to the cost of routine oil changes, the expenditures associated with excessive oil use can pile up.
According to Consumer Reports research, there is no clear link between greater oil usage and other engine issues. Our survey data, which covered 10 model years, reveals that an oil-burning car will continue to do so as it ages. Engine families exhibit rising oil consumption with each additional year on the road when oil consumption is tracked by model year.
If you are diligent about checking your oil levels, adding oil won’t necessarily leave you stranded on the side of the road. However, we consider it to be a major issue that automakers ought to address.
Not all engines experience this issue. In fact, according to our research, 98 percent of owners of automobiles made from 2010 to 2014 did not need to add oil in between oil changes. The cars that do consume oil, however, do so quickly. Even if only 2% of the cars sold since 2010 have this issue, there are still 1.5 million cars on the road.
According to Consumer Reports, the powertrain warranty should be used to fix any engine that burns oil in between oil changes. However, automakers frequently hide their intentions in the small print of their owners’ manuals.
