Should I get a high mileage used q7?
 

I have been reading this forum for a while and I test drove a few of these cars but I was really impressed with the ride and interior, very comfortable and nice. I also like the styling. I was looking at around an 06 @ about 8k... Do these cars hold up past 130k? My other option is a lexus rx330 which i know can go 300k if its been maintained but I really prefer the style and interior of this car. I also plan to take it for long trips/commutes so the nicer interior would be preferable. I've owned many mercedes which have been relatively carefree but have always been a bit wary of audis with high mileage.

you answered your own question
 

the key to ANY used car is service. I religiously service my 2012 well beyond factory recommended service including things like servicing the trans at 70k etc. if you follow the paper trail you can see how a car is maintained. My 2012 has 120k on it and it looks and drives like new and I have never had any failure issues at all I have a few pics in my profile.
I keep thinking I should get a new one but mine does everything I ask of it and really is flawless. I do think the 2012 and on resolved a lot of the early car issues such as sunroof drains etc etc there are numerous threads here about some if the older issues. good luck.

166k on mine so far.
I did have to get a cat replaced but that was the fault of the previous owner letting some morons work on the car.
The tranny was starting to act up, so I had the fluid changed. all good now.

I just bought my used 2008 Q7 less than a month ago. So far it has a bad oil leak diagnosed as a failed crankshaft oil seal and a misfire on cylinder 2.
The oil seal isn’t an expensive repair, only about $250 bucks. The misfire on the other hand is a bit of a mystery and most likely is a dying injector. My Q7 is at a German auto specialist shop right now having those issues repaired. The injector is about $180 bucks and I will ONLY buy the OEM replacement, no knock offs. Access to the injectors is a nightmare.... Upper and lower intakes have to be removed to access the injectors. Luckily I’m only replacing one so only one lower intake has to come off, not both. However the labor cost there is about 500 bucks in shop time.
I’ve already had to replace the battery which was about $500 bucks with labor because the drivers seat has to come out and computer programming has to be done when you swap the batteries on these.

Right now I paid 6k for my used Q7. It’s a fully loaded premium with the 4.2 and other than the quirks I’m dealing with it’s a flawless vehicle. I’ll be at about 2k into repairs here soon and hoping I can get a few solid years out of it before it’s time to sell and move on. Right now I love it and the exhaust note that comes from the 4.2 V8 is just angry! This is no Ford Escape lol.

I have 150,000mi on mine and from what I’ve been told that’s not even broken in yet for these Q7’s so I’m hoping to hold onto it for quite a while. Trade value is around 6500-7000 and private party value is about 8000-9000 so I figure even with repairs I’m still in the green, for now.

Its probably due for a timing chain but I’m not sure if that was ever done, very unlikely. I won’t be doing that because that’s 2,500-3,500 bucks easy and that would push me deep into the red on cost vs value.

Other than my few little issues I still love mine and I’m hoping to hang onto it as long as I can!

An 06 with 130,000 miles for 8k? Not terrible but seems a bit steep. I paid 6k for my 2008 Q7 with 150,000 miles and mine is the Q7 Premium 4.2 V8 with winter, towing, and premium sound package. I’d get the VIN and pull actual NADA and KBB values on that vehicle, as well as a full CARFAX.

no

Did the shop test the injector on a scope to know it was actually bad?
This is why I don’t let shops touch my cars.
Dont evwr tell me something is bad without showing me proof especially if it’s time consuming to get to it.
U don’t need to get to the physical injector to test it.
U can scope it’s current draw and compare it to the others. If it’s failing u will see it.
As for timing CHAIN why in the world would a chain ever need to be replaced. Maybe if at 300,000 or 500,000 it’s possible bust still not an issue.

Well, it doesn’t appear to be an injector issue causing the misfire on cylinder 2. Here’s a shot of the lower left intake manifold, specifically right over cylinder 2. Anyone see the problem?

Lower Left Intake Manifold Over Cylinder 2

Just basing the need for replacing the timing chain off of other people’s posts and the Q7 service manual. Recommendation is to replace the timing chain at 150,000 miles. Haven’t found anything or anyone stating that they had sudden catastrophic failure around 150,000 miles from a timing chain issue. I could understand if it was a timing BELT but the V8 chain is pretty tough. My only concern is the chain tensioner guides getting worn and causing slack to develop. Too much slack and you skip teeth. Too much skipping and you bend rods.... That was my thought process.

I have on 08 with 111K miles on it which has been very good. I have had both rear O2 sensors ($45 each) go at once and a high pressure AC sensor ($18) go. Other than that it's been rock solid. I am selling it now as I just bought a 2012 TDI with 18K on it which I plan on keeping for a long while. I had an 04 RX330 before the 08 Q7 & could not stand driving it. The RX had a bad radiator, condenser, & wheel bearing & all were a pain to do as the hardware rusts. The Q7 is one of the best cars I have owned & is pretty nice to work on. It's also the best for long trips.
