2019 3.0 Q7 New Owner Concerns

[Gunmeister]

Just recently purchased a 2019 Q7 with 29k. I was wondering if anyone knows of any issues we should be aware of to get addressed before the Q7 is out of warranty.

The only thing at the moment I was concerned about is if the 3.0 has oil consumption issues because we just has the oil changed 2 days ago and have driven it about 60 miles and the tech barely filled the oil above minimum and now within 2 days the oil has dropped to minimum line.303972303973

Oil should have been all the way full when leaving the dealer.

Between your two photos It’s down one bar but it appears you’re checking in two different locations. The mmi can be very finicky. Always check in the same spot with engine warm. Then shut the car off, open hood, close hood, and recheck. Opening the hood resets the computer for a new oil level reading. With the low miles unluckily it’s burning but there have been reports of the gen 2 3 liter burning oil. Most have higher mileage. 80k+

I have the same question/concerns about oil consumption. I have a 2018 I purchased in december as a CPO with 19,300 miles on it. I changed the oil once I got it home and since I have needed to add 1.5qts in 4,000 miles. I change my oil every 5,000 miles. I thought this was excessive. My daily beater 2004 A4 avant 1.8t with 250,000 miles only burns about 1/2 a Qt every 5,000 miles. And my sons 2009 A4 avant 2.0 with 160,000 miles doesn't burn anything.
I have an appointment to bring my Q7 in to have them start to log and document oil consumption. But it seems like they are already trying to tell me this is normal for this engine platform. I had thought the 3.0 supercharged engine, especially the final iteration in the Q7 was fairly rock solid.

Sent from my SM-G986U using TapatalkLet me know how it goes. I'll keep documenting mine too, but I literally just bought mine, so i dont have good data. How much was your Q7 if you dont kind me asking? Mine was 51k. My oil level was 1/2 full and 4k from the previous change. Have you had any other issues? I had a 2012 A6 3.0 and I thought they were the same engine, which I did not have oil consumption issues until like 160k.

[allbizns]

My oil level was at 1/2 level when I purchased also. According to the record's mine had just received the Audi care 30,000-mile service 2,000 miles before I purchased it. I drove 700 miles to get mine. It was in Florida. I paid $45.5k in November.
2 weeks into ownership, it thru a code for cyl 1 misfire and multiple random misfires. It was definitely running on 5 cyl. Took it in, and they said the plugs were bad. Not covered under warranty because it's a wear item and wanted almost $800.00 to replace all 6 at 20,000 miles. We argued back and forth, and they finally agreed to replace the 2 faulty plugs for free, but not all. When I looked at the plugs, it was carboned up fairly good. At that point, I began to question oil burning/ consumption. But they made every argument to deny the possibility. Needless to say, I'm going to change all the plugs right before the next service at 26,000 miles. Hold on to them and bring it in to begin the oil consumption watch with the dealer.
I hope it all is good because my wife really loves it. We replaced a 2013 Q7 TDI with this. i was hoping the 3.0 was going to be a stable platform and less maintenance cost than the TDI. So far, it doesn't see that way, unfortunately.

I will keep you posted on the progress.

My wife loves hers, too. Sounds like you got a better deal than me price wise. What was the spec? That's alarming for plugs to fail that fast. Hopefully, as the milage goes up, the consumption goes down. My 2016 A6 TDI has never had an issue currently at 65k.

[allbizns]

Our 13 Q7 TDI was fairly trouble free. It had a few things on the emissions side that needed attention, but the diesel gate extended warranty was awesome and covered everything. Really one of the biggest reasons I decided to sell the TDI was the warranty ended, and we no longer put the miles on like we used to. So it was the fear of dealing with the emissions equipment when or if the time came.
Our new one is a Prestige every option except Adaptive suspension and Luxury package. So no massaging seats lol...

It happened to ours, about 5000 miles it needed to ad a quart, had to use the last Audicare free oil change. After that I switched to do my own oil with Liqui Moly and last 2 oil change (@5000 miles interval) it never lose a drop.

Sent from my iPhone using TapatalkIntresting, I only used Liquid Moly on my TDI Q7 never lost a drop. I tried the highly talked about Castrol Edge Euro 0W40 on my first change. I have enough Liquid Moly left over from my TDI I had considered using it. It is a 507.00 spec, which all the data I can find says that it is an approved oil spec along with the 504.00.

Yea I believe it SB the velocity of the oil. Same thing happened to my S6, I’m watching this time and see if there’s oil loss within 5k. Past 2 oil change was performed by dealer because they had to work on recall and warranty repair which required them to put in new oil.

Sent from my iPhone using TapatalkThat was my thought on the viscosity as well. Which Liquid Moly are you running? I assume the 5w/40 Molygen in the green bottle. I have the 4200 Long Life left from the tdi. It's a 5w/30. The only struggle is I've got 4 audi care services that transferred with the car when I purchased it. I'm trying to decide if I want to use them.

My GF decided to pick up a’17 Prestige with a little over 100k about a year and a half ago. I decided to do coils/plugs/filters and oil almost immediately to have a solid maintenance baseline.

It was going through a liter every 1700, basically 3L between 5k oil changes. I had hoped that some shorter OCIs with high quality oil would help remedy it a bit, but no. This is when I found that the CREC was plagued by similar consumption issues at the infamous 2.0T, which I am very familiar with.

I decided to take the cleaning, that I had hoped the oil would do, a bit further with a Liquid Moly Engine flush, results below.

Mileage-Consumption
104-109-3L
109-114-3L
114*-119-1.3L *1st flush
119*-124-1.3L *2nd flush
124-129-.8L

So the first flush really did all the work.
Theory is that the residual flush dilutes the oil a bit as most of the usage following the first two flushes was in the first 800 miles, then It stabilizes after adding a liter, this did not happen as the last change was just oil, no flush, no need to top off.

For all we know the PO was just adding oil as needed for 10’s of thousands of miles in between 10k+ OCIs.

Personally I’m happy with the results/consumption for now being over 130k.

Note, outside of the 10k OCIs (and flawed piston/ring design) short trips can be blamed for the consumption issues. Audi only considers oil consumption an issue if it exceeds 1L per 1k miles.

There are more drastic measures that can be taken if the alternative is a rebuild, like here:

To clarify, all you did was utilize the liqui-moly oil flush additive per the label instructions? No chemical soak or any other additional steps?

If so, I am trying this on my next oil change.

Thanks again.

Yes, as per instructions, idle for 10ish minutes and drain.

That said, on my first oil change I went from the bottom, never again. The oil drain plug is right in the middle of the pan facing down, hot oil came out fast enough to hit the drain pan and bounce out, lovely. This is aside from having to remove the belly pan as is typical for Audi.

I now use a pneumatic extractor, oil filter changes take less that 10 minutes. I do put the nose down at an angle in the driveway to push the oil towards the dipstick tube and since it’s graduated I know how much I’m pulling out.

For reference, I do have to elevate the extractor on a stool for the Q7 and I got one of the larger ones to accommodate the Q7 capacity. Don’t forget the 36mm socket for the oil filter housing. Enjoy $60-$70 oil changes.

Thanks for sharing JLAllroad, will give it a try. Is this the product (Pro-Line Engine Flush) you used and did you just use one can?

Correct, 1 can, which is good for 3-5L, it was at about 6L at the time.

JLALLROAD,

I have a couple questions, if you don't mind sharing:

(1) did you dump one bottle of LM engine flush to roughly 6 liters of oil? (that's what I inferred from your comments)
(2) after the flush/oil change, did you let the new oil circulate for a while and change the oil a second time on the same day?
(3) if doing again, would you even bother to do a second and third treatment at your next oil change intervals?

Thanks much

1.when doing either of the two flushes we were at 5k and it was hitting the “add oil” prompt, which would be about 6L left to which I added the LM flush.

2. Idled with the flush for 10-15minutes, drained, filled with LM hightech 5-40 and a new filter and ran it for another 5k, topping of as needed/described.

3.as noted I found the benefits were realized on the initial treatment, the only reason to repeat is if consumption increases from the new baseline.

Note, those that have done B12 piston soaks have been able to get their consumption to almost nothing.

I did come across a video on this product recently, the downsides, not available in 5w-40 and doesn’t carry any of the VW certifications.

Hello, how is your consumption so far? Might try this out on my 2016 A6 before jumping to a piston soak.
