View Full Version : New (to me) 2012 Audi A6 (C7) 3.0tdi Quattro SE experience so far...First post!

Hi all,
Having had numerous BMW's and Mercedes (all 3.0 diesels - 335d, X3, C350 and thoroughly enjoying them) I thought I'd try an Audi for a change.

I typically drive 20k miles a year so a diesel is better and obviously a V6.

I took a punt on an unloved 2012 A6 Avant Quattro SE spec - 18" wheels, 3 spoke steering wheel, Audi USB connection thing, DAB and ambient lighting.

I had to give it a full service and replace some missing trim, but £12k with 100k on the clock I thought it was worth it.

Servicing was easy except the air box was a little fiddly. Fuel filter was fine, I didn't use VCDS just pressed the ignition on and off a few times and you can hear the fuel pump working.

I'm glad I removed the scuttle panel, everything was blocked so it was reassuring to clean that area and open all the drain holes etc.

First impressions:

The satnav is embarrassingly poor quality to look at with standard system and updates are £300 odd so I won’t be relying on that too much! My 2009 C350 was far superior quality. To be far the ’09 X3 and my mates ’12 Disco 4 are of equally rubbish quality.

But it’s comfortable; has a respectable turn of speed for a big quattro estate car; nice level of toys and good lights.

7 speed S-Tronic gearbox is smooth and well matched to the engine.

I like the high profile 18" tyre comfort but combined with SE suspension it was poor on the corners compared to what I was used to. However, 5k miles on and I'm totally used to the handling and rarely miss the M-Sport or AMG Sport's of my past.

Gearbox was easy to service. I did the whole job so that was new gasket, oil strainer and the external filter for less than £200 and managed to get out about 6 litres of oil - which actually looked pretty clean.

This is where things went a bit wrong...

We had the car on my mechanic mates' lift to make the job easier. We used the replacement external oil filter housing that came with the Meyle service kit. 500 miles later the car's gearbox went into limp mode and refused to drive. Getting it back up on the ramp and you could see that the filter housing was off!!

It had completely emptied of oil :(

Needless to say I was glad I was wearing my brown trousers that day.

Further investigation showed that the replacement housing lacked the "belt and braces" outer engagement locking teeth on the flange of the original. Whether that was the reason for the housing coming off or not I'll never know but I reused the old one, replaced the filter again and put in another 6 litres of DSG oil.

The gearbox engaged immediately but I still carried out the VCDS clutch and sensor re-calibration anyway!

After 1000 miles it threw up an error code which came and went in 1 second:


"9473 - Sensor for Gear Actuator 2 - P17E1 00 [032] - Mechanical Malfunction"

I cleared this, checked the filter housing again and it's tight so I just hope it's not the sign of imminent problems. I've since done another 500 miles without issue.

One final note; as a result of the system peeing oil everywhere under the car under pressure it's obviously filled some nook or cavity because when I'm idling on a hill I can smell gearbox oil inside the car!

Normal driving gives no smell. It's a bit annoying but will hopefully clear soon!

Sorry for the rambling first post! In summary I really like the car and will keep it as long as I can especially now I've invested in VCDS for messing around.

Servicing is simple, it's huge, practical, economical, comfy and fast enough.

One question... Is it easy/safe to remove the boot opening seal and refit as some of the carpet has come out I want to correct it all.

One final note - wow the expansion tank was filthy and impossible to see the level! My wife's 11 year old focus's is still crystal clear, why is the Audi so ingrained with rust/dirt, photos on google show that it's not unusual!

Cheers,

James

BTW, for those who are interested I used a Sealey Transmission Oil Filling System 3ltr VS70095 to put oil back into the transmission sump. It actually comes with the correct nozzles to do 6 speed DSG, 6 speed ZF box and the 7 speed Merc GB - all of which I've done over the years - a brilliantly useful tool.

Hi, thanks!

It's not exactly the sexiest model but the 18" wheels help and I've recently had the rear windows tinted so it looks much better and, of course, it's better for the kids and (almost as importantly) my mountain bikes!

Oolong grey which is about as much as I know, need to phone the original supplying dealer to try and find exact spec. I'm pretty ignorant when it comes to Audi so this site is prooving invaluable so far! VCDS is some tool too!

Cheers

Welcome, with regards to the smell I had something similar in my old a6 that had a leaking fuel rail. Audi replaced the whole under tray, I'm sure a good clean would have done. The other thing to change is the pollen filter in case some of the oil is trapped there.

Good idea, I'll clean the tray and change the filter this weekend. Fingers crossed.

Welcome :)
Where do you plan on putting your bikes?
I have a roof rack that floats between the wife's Touran (mostly) and my A6, but it's an MPG killer, even with no bikes on it...

Hi Mintyjim, I also have a 2012 A6 Avant. I also do MTB and put mine on a Thule tow bar mounted bike rack. 3 bikes on the back almost equal what I paid for the car lol. I can honestly say it
doesn't move even when doing some serious MPH. Wouldn't change it for any other.

Car looks great for 100,000 miles and £12k sounds like a good buy.

Regarding my bikes, if it's just me it goes in the boot - hence the window tint - otherwise I've got a few roof mounted bike racks on Thule Wingbars. In the springtime I'll buy and fit a tow bar so I can use the towbar mounted Thule rack for my annual Alps summer trip.

Agreed with Pikey Narna... 3 bikes on the back nearly financially balances out the whole car! Although since the birth of my daughter I'm only down to two.

Thanks Belly Buster. I spent £100 on oil and all filters, £500 on 4 x Dunlop Sportmaxx RT2, £60 on replacement parcel shelf and £15 on a missing door clip. Plus I emptied, cleaned and replaced the coolant.

Including the gearbox service I was on the road for £12,885. Happy days.

Wish I wasn't so nervous to refit the inner boot seal! My car OCD is strong on this one...

Another quick one...

I don't have the rear damping tray under my car, part number 4G0863822C, see photo, it sits under the gearbox brace. Best price I can find is £120 from Cardiff Audi (I live in darkest West Wales).

32398

Again my OCD is pushing me towards getting this, anyone think this would improve sound insulation to a noticeable level and provide protection?

Anyone beat that price?!

Cheers

My old C4 Avant I would throw my Tri bike in the back for trips, but the dirty bike would always be on the roof.
I'd be interested to see if you do get less mpg with the tow bar/rear rack

Hi, it's nice to see people are still doing-it-themselves with these new cars that really are just computers on wheels. This is particularly interesting, as I've got my mind set on getting a fairly well used A7 sometime this year. And after this recent ice blast, it will have to be Quattro. I own an Autel MaxiDAS DS708. It's no VCDS, but it's competent with my current A4.

I'll come back for some advice when I take the punt. Like you said, at the price they go for, it's hard to argue. We'll see... Thanks!

you definitely suffer on fuel economy but much less than with bikes on the roof!

New cars aren't that complicated really! They still have all the fundamental technology of older cars - belts/chains, filters, A/C compressors, radiators, intercoolers. Apart from the ICE technology and numerous ECU's there's very little difference working on my 1995 Mitsubishi 2.8TD Delica and the A6 - I kid you not!

Regular servicing, suspension/steering links, brakes etc is almost exactly the same on both! However DPF's / EGR's can be a nuisance but with my annual mileage and mix of driving I should, fingers crossed, get away with it! That's probably the kiss of death...
