Thanks for another Great video! As I bought a used Vw Passat 6 months ago. I made sure to follow your inspection, prior to purchase. Runs like a clock and I just did an inspection and oilservice on it 😊

[@ChrisR14]

The dtc optical databus open circuit in the Gateway and "invalid wake request" in the 5F unit on these cars are a software issue on all B8.5 MY2014 models equipped with the MMI Navigation and leads to delayed booting of the MMI when starting the car sometimes. Update the MMI to latest K0942 fimware and the Gateway to SW 0060 and it will be fixed. ;-)

That would be really cool If he can show us how to update firmware on VW and Audi infotainment units. I don't think it's possible outside the dealer, it's like the holy grail on the MK7 Golf forums

Owned my B8.5 S4 since new and live in CLE next to a Morton salt factory (no joke, I see the dump trucks all the time). My exhaust clamps simply fell apart and looked like that on inspection up until that point (15:30). What I’m saying is: You may not have had an aftermarket exhaust on at first. Could be like me where they disintegrated. New clamps fix this quickly due to the design of the flex section in the DP. Now the flex sections on the DPs are my next worry as time goes on…they look crusty at 87k miles.

[@stevenplaskett7728]

The best way I found to inspect my 03 allroad was a drive on hoist. I have loud clunking in the front and I could not identify the bad ones until I had someone creep forward and step on the brakes a few times. Then it clearly was seen the lower rears were shot and very loose. eBay had great deals I have 2 in the mail for it.

[@jollyrodger1537]

Thanks. I just did upper lower and tie rods. some clunking noise in suspension.....just after that on the test drive. my transmission cooler line failed blew fluid out the passenger side front grill and is was pretty scary. tires were losing some grip before i knew what happened I can say after 1 yr of driving it it is a great car. but the car is a lot more expensive to fix than the 2.0T engines that I drove in the past. I have put probably 6k in it and havent fixed an oxygen sensor or worse problem in the exhaust. beware if you are buying high mileage car and love to keep your car running great

[@PreetSingh-gp3re]

Love the s4, you forgot to mention the idle shake which not an issue but just inherit by design. Feels like your sitting in a muscle car.

We have a 2016 3.0 tdi quattro, best all rounder. However our 2017 volvo xc90 hybrid is in another league. Our 2015 Q7 was a pleasure to drive until some moron t-boned it. A little underpowered though. If I had the money I'd go out and purchase an SQ7. I test drove a 2017 model. It was in a league of it's own. The power & acceleration was unbelievable.

[@alj7094]

Useful content as usual Paul. Having a quick question here. On my 2017 mk7 GTI I have roughly about 25500 miles on it. I would say 75-80% is highway mileage. Would that be a lot different (in a good or bad way) than those ones with 75 80% of city mileage?

[@norzatoivokapapilo9117]

Great to see this video. I have a 2012 S4 3.0TSFI with 121 000km, recently it started consuming a lot of coolant water and one could see steam coming out of the exhaust when driving slow. Now i would like to know what could be the problem? Is it probably the waterpump issue or is it the top gasket or any other piping. I would like to know before i take it to the audi garage.

[@wildbill6976]

steam from exhaust usually means a bad head gasket

[@abdullahsekai4279]

oh god. This comment.

[@Steve_with_coffee]

Did you ever sort the issue out? Was it a combination of normal condensation and steam from the catalysts and a leaking connection, thermostat, etc, looking like related issues, or was it something worse like head gaskets or leaking coolers in the supercharger?

[@abeibrahim5846]

Hi, Great video - I wonder how I can tell, what is my car C# is? in your "Common Issues with 3.0T (Supercharged) TFSI Audi Engines", it indicates that "A6, C5 platform 2009 - 2011"; well my car is 2010 A6 and I thought it was C6, other Auto sites indicates that my engine 3.0L Supercharge is really a C7.

Is it possible to see how many times your car has been launch??..( I just started getting into cars )

[@FractilOpacity]

I just bought a 2012 Audi A7 and have had issues with the Adaptive Cruise control right after purchasing the car, but the dealership is being good and has done about $6k worth of work (new lower "foglight" sensor, control module, windshield, wheel alignment and calibration of both systems) so far for free. So as a note for test drives, use the cruise control!! Another thing I'm not too worried about is the transmission feels a little rough when slowing down, I take that more as character though.

The write up about the “Audi Models with the 3.0T TFSI Gen1 Engine” lists SQ5 model year 2015 - 2017. What about the 2014? The SQ5 was released in the US in 2014 and as far as I can tell, has the same engine. Good write up.

Hi! would you please explain what is the difference why some s4 have two different kinds of stering wheel?

the B8 model up to 2012 has a round steering wheel and the 2013-2016 B8.5 has the flat bottom.

The heated steering wheel in the B8.5 is round, the non-heated steering wheel is flat bottomed.

[@dannyboy8067]

Very informative but who is going to have the chance to do that in the showroom or on the roadside?

[@Deutscheautoparts]

If you are buying a used car you should either inspect it or pay for a 3rd party pre purchase inspection. If they tell you they wont allow it, find a new place to buy a car.

[@ScottSellsSoCal]

Great video. Question, how does one find the chassis codes to their Audi’s? What’s the code for a 2017 Q7?

[@johndale9578]

My 14 s4 rattles breifly upon start up then it clears. I asked Parker Audi in Little Rock, Ar and they said this is a normal finding. What do you think

[@wildbill6976]

most likely timing chain tensioners, oil runs off if engine isn't run for a few days, and will rattle a bit until oil pressure builds back up on starting; nothing to worry about unless it rattles all the time, common on most things

[@xDOMINICANz]

John Dale same problem I have, I was worried at first but it’s pretty normal

There is no such belt. Engine is timing chain driven, and it is located in the rear like the 4.2 (requires engine removal to service).

124k is considered high mileage for one of these? I'm new to Audi..

[@JSB1729]

I think he meant high mileage for the year. 124k miles for a 2014 car is pretty high regardless of what it is. Also, this video was shot in 2018 so that was only a 4 year period.

[@Usef320]

ikr just bought an s4 and im scared lul

[@Usef320]

@Draggy654 im not worried about the engine, just literally everything else

[@HISHAM931]

124k miles is extremely high mileage on a car that is 4 years old (video was shot in 2018). You can still find a B8.5 S4 with significantly less mileage. Parts are very pricey for this car, you don’t want to be in a situation where you get the car for cheap, yet the repairs going down the road may cost you more than the value of the car. Like here in Montreal there are so many used B8.5 S4’s that sell for around $15-20K, with around 80-90K miles on them.

[@dagnut]

Awesome vid! Glad its S4 time, appreciate the links as well. What are you thoughts on the timing chain tensioner "chain rattle noise on cold start" issue? I understand there is a TSB out since 2015 (which says no damage is occurring) and much debate online regarding if this is a real issue and whether the fix might be worse than living with it. Does your S4 have this noise at start up? If so I'm leaning towards not fixing mine. 15 Engine rattling noises at cold start - V6 3.0 TFSI 15 15 26 2039995/1 March 3, 2015. Model(s) Year VIN Range Vehicle-Specific Equipment All 2011 - 2014 All V6 3.0 TFSI Condition Rattling noises are heard from the timing chain drive for about 1-3 seconds after the first engine start of the day. Technical Background The noises are caused by one of the upper chain tensioners. The noises do not lead to damage. Production Solution Improved chain tensioner.

[@LynxStarAuto]

Onearm Bandit changing the tensioner will only result in a short term fix. As they wear, the slack when the engine has been sitting for hours will cause cold start rattle which should immediately go away. It's a shit design, with no permanent fix, and requires engine removal to do it.

[@kdshiv]

Lynx Star Automotive Thanks for the reply. If it is just a sound issue then great. What worries me is that Audi is repairing it under warranty and given the time/cost involved of an engine out repair they must think it's necessary? I'm all for not fixing it if it doesn't cause a mechanical failure down the road. I'm just trying to find the right thing to do as I'm no mechanic. Sounds like your advice is leave it alone even if under warranty?

[@IYG-x7c]

So did they end up improving chain tensioner in later years?

[@kdshiv]

Ilya Elis for the 2017 model year a turbo charged engine replaced the supercharged, but I'm not sure about the timing chain tensioner specifically.

[@IYG-x7c]

Onearm Bandit Yeah I know, but I think it's safer to get B8.5 instead of B9 for reliability maybe. That turbo engine and B9 platform are new. Not sure though.....

I think this is to do with the rear differential. My 2011 S4 does that as well but only low speed manoeuvres at or close to full lock. It sounds almost like a distant, deep grinding noise? I also drove a friend’s 2010 S4 before I bought mine and his had this characteristic too. It’s nothing to be concerned about.
