Спасибо. Отличное видео

[@grilledchickenwrap]

Jesus christ the control arms and everything engine is clean!! wow !! wish I can pick something up like that.

[@maverick_da1735]

Finally a good video on the Q7! Thank you. I currently reached 107k on my 2018 / 3.0 without any problems thus far. I do oil changed every 5k and add a half or a quart in between do to engine burn which I haven't found a reason as to why though the Q7s burn. .. Anyhow I'm about to do all the same maintenance so thank you for this video! Did you notice any difference on differential with new fluids? I've heard it could start slipping once changed not sure how true that it, but I'm changing it. Again great video!

To shine some light on the oil consumption of the audi 2.0T and 3.0T. I had a 2013 Q5 with the 2.0T engine which had 45K miles on it when I bought it. Oil consumption was about 1 quart between oil changes, when I reached around 110K miles on the engine, it really started consuming a lot more oil, up to 3 quarts between oil changes. I started looking deeper into this issue and found some literature where Audi is well aware of this issue, they even had a TSB (technical service bulletin) in regards to this oil consumption issue where Audi in many cases would take care of it up to 100K miles on the engine. The problem is the piston rings not sealing properly and letting oil seep into the combustion end of the system thus burning it off through the exhaust. Really only way audi can repair this is with a partial engine rebuild by replacing the cylinder pack, liners and rings OR a complete engine swap replacement. Now I have a 2017 Audi Q7 3.0L with 85K miles and zero issues in regards to oil consumption but that is not to say that Audi fixed their known problem. Many people out there still have the oil consumption issue and most dealers would tell you that it's normal which is far from normal in my option. Vehicles manufactured in Germany for the European market don't have this problem, or it's very minimal in comparison to Audi vehicles designated for the U.S. market which parts are sources from many different countries like Bulgaria or Mexico for instance and are also mainly assembled there and not in Germany. So to sum it up, any 2.0T or 3.0T engine designated for the U.S. marked is prone to oil consumption for about a decade now and Audi is well aware of that. Hopefully this helps some current owners and future buyers in their decision making when considering these two types of engine made by Audi for the U.S. market

Good job brotha. Do you know what size socket requires the crankshaft bolt by any chance ?

[@user-ng3ew1eb9o]

Do you know exact spec of transfer case drain bolt? It looks M14*1.5 with h6 hexa allen. same as engine oil drain plug?

[@lauretiu]

i just went and checked every single website that i could find talked with customer support and i was told the water pump you used is the wrong one for this car. 06E121018H is the corect one and you installed 06E121018K. i'm no expert by any means just taught i should point that out since i asked everyone based on vin (q7 4m 2018 3.0t prestige) and i got the same answer from all of them that 06E121018H is the pump i should buy. besides that thank you for all the other info. i need to do all this service myself

[@PrecisionAutoSource]

Both will work, H is the OEM plastic impeller K is the metal one.

[@reelrocknrolla4251]

So the K is better it seems

[@xxlliquid]

Awesome work! do you know if the vw/Audi transmission they use in some Q7s is gonna need the same oil and capacity as the zf one ?

[@PrecisionAutoSource]

Pretty much the same process on the 6 speeds as well. They take 5-6 drain/fill, same procedure for filling. If you follow the procedure you cannot under/overfill.

[@stanghp1]

Great work!!! Do you happen to know the drain and fill capacity for the front, center and rear differential?

[@PrecisionAutoSource]

Front-1qt center- 0.8qt, rear 0.89qt

[@narvinbeans]

I have the same issue with my exhaust being cracked in that spot at 2:09. Do you think this is due to a bad flex pipe? My flex pipe portion of the exhaust and the broken exhaust part is shaking like CRAZY. The motor is solid no shakes

[@PrecisionAutoSource]

Yes...flex pipes go bad...New pipes are about $900. I just live with it for now.

[@xiaoma466]

I also have the same issue with the exhaust pipe. Mine 70k

[@GOOD__DUDE]

hey, i have the same vehicle. does it burn oil? Mine needs about 1L every 2000 miles. Do you think this can be caused by a bad PCV? Thanks and great video.

[@PrecisionAutoSource]

Good timing! Just added 1/2 quart after 4k miles( including 2 500 mile tows). That brought my level up to max. It was showing a notch below half before. Try the oil I suggested next time.

[@Ivan-pe9yi]

I replaced Pcv and check valve on mine. Still burnt a qt. of oil ever 5-550 miles. So decided to do a piston soak. I’m currently around 1,0xx and still no need to add oil 🙂. Maybe go that route first.

[@GOOD__DUDE]

Thank you Ivan and I ended up having my PCV valve replaced. So far I have 600 miles and it doesn't seem to be burning oil...Do you mind me asking what it cost you to have your PCV/Check valve changed and did you do it at a dealer? Also, was the piston soak a hard procedure to do?@@Ivan-pe9yi

[@GOOD__DUDE]

@@Ivan-pe9yi how many miles does your Q7 have and is it a 2018?

[@GOOD__DUDE]

@@Ivan-pe9yi hi, could you tell me where you saw the instructions to do the piston soak? Has the car burnt any oil? Also, what year is your Audi Q7? Thank you Ivan!

[@mightymoe4635]

Can you do a transmission service on a 2018+ Audi Q5 2.0T???

[@PrecisionAutoSource]

Same process as this one.

[@mightymoe4635]

@@PrecisionAutoSource Did you replace the 2 tranny filters also?

[@jeanvenant1801]

My local Audi dealer stated that the transmission on my 2017 q7 is not serviceable, and the differentials are not serviceable. Is that accurate?

[@PrecisionAutoSource]

Not Accurate, they are very much so. The dealer will tell you lifetime fluids which translates into lasting until your factory warranty expires. Lifetime fluids do not exist...all loose their original lubricating properties over time. Even the manufacturer of the transmission (ZF) recommends changing every 50k.

[@lermos]

Ха-ха-ха, привет из России. Дилер вам врёт, чтобы вы приехали на дорогостоящий ремонт коробки и всех редукторов. Меняйте масло чаще

[@evaldasradzevicius9694]

What fluid do you use for transfer case?

[@PrecisionAutoSource]

Check the description I listed the part numbers there

[@aesca151]

Is this also the same for the 2.0?

[@PrecisionAutoSource]

Should be similar

[@podium918]

I bought a car at carmax and it smelled bad off coolant . I took it back before 90 days and was told it was a water pump and when I got it back they didn’t even do the pump and I was lied too
