2014 Q5 2.0 liter US engine improvements?

[Masquernom]

I'm considering purchasing a 2014 Q5 with the US 2.0 liter engine. I held off on buying the 2013 because of concerns about carbon build up in the intake/valves, and unresolved oil consumption problems.

The 2014 US engine seems to have had some improvements made. They added a fifth fuel injector, that I hope will help with the carbon buildup problem. I don't know if they made any changes to address the oil consumption problem.

Anyone here with a 2014 version of the 2.0 liter US engine having the high oil consumption problem? Your oil light ever come on between oil changes?

That is the same engine that is in the B8 A4 from 2009 till now. Most of the oil consumption issues stopped after the 2011 MY. A few 2012 cars had the problem, but very few of the 2013 and 2014. Check the B8A4 section, there is a sticky thread on the oil consumption.

Since it is essential same engine, why did it stop or is it just later model years haven't accumulated the mileage yet?

Audi had 3 fixes for it. First was a combination ECU update and PCV valve update. That seems to work 50% or more of the time. The rest of the time they would follow on with piston and ring replacement. Those updates were put in place somewhere during MY 11 so very few of the new cars had that issue.

That's nice to know, how about on the 3.0T engine, did they do something similar in for MY11?
and what's more important since I am looking 2011 3.0T models... how do I know if my 3.0T is an improved version or not. Sorry for the hijacking..

According to the posts from owners of the 2011 and 2012 US Q5's online, those model year 2.0 liter engines still have the oil consumption problem. But I've only checked the Q5 forums. I plan to hold off till at least the middle of 2014 to make a purchase. Should have a better idea by then. The posts about the problem online do appear to have slowed down, so maybe Audi is making progress on the problem.

Stubek, is the ecu and pcv update documented officially somewhere by Audi? I'd be happy to read that.

No idea on the 3.0.
As I said, for complete info including posted copies of the TSBs related and lots of details, check the B8A4 forum sticky. Its been going for several years, but start near the end or ask in that forum as more people read there.

Thanks will check the TSBs.

This doesn't directly address your question but as an FYI, I have a 2013 2.0 that used about 1/2 quart in the first 2k or so miles. Since the 5k service no consumption at all in 2k+ miles. Same driving style/conditions. So for now I'm considering it a non-issue. Fingers crossed...

From what I've seen, there are a couple major improvements to the 2013+ engine to address oil consumption and broken intake manifolds.

Oil consumption, I am assuming the fixes to my old 09 A4 are standard on the current 2013+ engine while personal experience seems to point to the same.
At 16k mi. on my 2013 q5 2.0t, I saw some oil consumption the first 5k mi and about or less than 1/5th a quart (according to the MMI) oil consumption over the next 8k mi.
This is pretty much on par with what I experienced on my 09 A4 after having the PCV and pistons replaced.

Regarding broken intake manifolds, the current unit now has a metal IM instead of plastic. Had the IM replaced on the A4 due to a valve popping out at the back of the plastic IM like many others.
Being made of metal, the entire IM now "seems" more robust than before.

Regarding a fifth fuel injector, pretty sure it's on both the 2013 and 2014 engines. Only difference between the 2013/2014's are supposedly the ecu tune. However, that 5th injector seems to be more for cold starts on e85 than for carbon buildup prevention.
On the other hand, I've been scoping the valves every 5k mi or so on my 2013 q5 and they have remained pretty clean (at least so far on the front two cylinders where I see nothing like the buildup I saw on my previous A4.)

Thanks everyone. That sounds encouraging. Seems the 2014 also has reduced steering effort. I test drove a used Q5 this year. The steering wasn't bad, but it was noticeably stiffer then most US vehicles. Lightening it up a little is probably a good thing.

I haven't driven anything yet I like as much as the Q5. We can get the supplier discount from Audi, so the Q5 is actually cheaper than any of the competitors I've looked at. So, I guess in the summer of 2014 I'll go ahead and place an order. I'll keep an eye on the forums till then.

Sorry for my short replies yesterday, work was nuts.

I have a 2011. After getting the PCV/ECU updates, I burn about 1 qt every 3-4k miles vs the old 1 qt every 500 miles. Still frustrating a little as my B6 1.8T that I had from new to 92000 miles never burned a drop.

I remember being at about 1qt/6k miles or so on my 09 a4. The PCV/ECU update did nothing while the pistons/ring replacement was what really fixed things. Basically the difference between carrying that extra quart of oil in the trunk or not.

+1

I got really lucky with my 09 A4, I was going through 1 qt every 4-5k which is nothing compared to ever 500.. that's insane

I've been checking the internet forums and starting to see posts where people are seeing the oil consumption problems with the 2013 Q5's. I'm still hoping the changes to the 2014 motor fix the problem. Still a big concern to me, and I'm still holding off on ordering a Q5.

I have a '13 2.0 that used about 1/2 quart in the 1st 1k-2k miles. Since then no consumption in the past 12 months. Fingers crossed. Initially I was disappointed but don't think about it any more. If it's a big issue for you there are several good alternative choices in this segment.

My 2014 Q5, 2.0T has not burned any oil in 2500 miles. I own the car since June (don't drive it much), I live in cold/snow country so I let it idle a long time (15 min+) after startup. I know this is against what most believe should be done, but after many cars doing this all my life I have yet to see any oil consumption issues due to idling. Well I have a manual dip sitick and both the MMI and dip stick still show that the oil level is full.

There have been many changes to the current US 2014 Q5, 2.0T engine. This engine version is the same as the European 2013. I have to go back to the part list but I believe that the piston and rings are new P/N's compared to the older 2.0T parts.

[Q5 Bob]

I think I read that 2013's had new piston and rings too. Not sure but enjoying no consumption after 7500 miles. The way it should be.

[Masquernom]

From what little I've seen, it does look like the 2014 US engine may have some changes to the piston sealing area. I couldn't find any details about what those changes are. I'm still waiting to see what happens. I've never owned a vehicle that used a quart of oil in 5,000 miles. I don't want to buy one now.

Just to let you know that may 2014 owner's manual states that oil usage at 1 quart per 1200 miles is acceptable. If you burn oil within that limit Audi will not do anything to make it better. If you can't live with that constraint then maybe an Audi is not for you. Remember that there is just a lot of hype around German cars. I have owned 3 Audi's, 3 Subaru Outbacks, 3 Nissan Z cars and 2 Maximas. I have to say that the Outbacks are the best for overall satisfaction.

I have the 14 2.0T. Haven't noticed any problems, but I still haven't ordered a dip stick to keep track.

Anyone have a way to check the part numbers and see if the 2013 and 2014 2.0's use the same piston rings?

Before August, 2013.....

Piston with rings P/N - 06H-107-065-DD, Rings only - 067-198-151-C



After August, 2013

Piston with rings P/N - 06h-107-065-DG, Rings only - 067-198-151-P

[Masquernom]

Those new part numbers would be about the time the 2014 Q5 came out. The engine has updates, so maybe they have addressed the oil consumption problem. At least maybe they're trying. That's promising news to me anyway. Thanks for looking that up FussyBob.
