I have an Audi A6 2009 with the 3.0 TDI 240hp engine code CDYA. The car is automatic. Ever since an accident on the front / passenger side of the vehicle, I’ve experienced random engine revs moving while in idle. This is also accompanied with sometimes white smoke from the exhausts.

The charge air system throttle valve module J338 does not require adaptation, its primary purpose is as an anti shudder shut down flap. The EGR change over flap does not have any electrical feedback, it is vacuum operated. 2010-2016 B8/B8.5 Audi S4 3.0T supercharged; 2013-2017 B8.5 Audi S5 3.0T supercharged; 2014-2018 Audi SQ5 3.0T supercharged; 2009-2017 Audi Q5 3.0T supercharged; 2012-2018 C7 Audi A6/A7 3.0T supercharged; 2011-2018 D4 Audi A8 3.0T supercharged; Does not fit Audi Q7, does not fit C6 Audi A6 3.0T models.

Original Poster 98 posts 190 months Saturday 20th July 2013 What's the general opinion of the previous generation Audi A6 Avant? Specifically the 2008 C6 Facelift, and ideally with the 2009 Quattro wise, the TFSI (300PS, V6 Supercharged petrol - detuned version of B8 S4 I believe) looks great... but I can't find a single one on Audi Approved Used or Autotrader, and only one here on Pistonheads. Is there something wrong with them? Or did everyone just buy the diesel because BIK tax/carbons/MPGs? I don't do enough private miles to care much about fuel consumption .So, as the petrol is in short supply, what about considering the the diesel? The TDI (240PS V6) seems to be in plentiful supply at around £17k-£19k for a 2010 Le Mans, and a quick search reckons a remap will give another 40-50BHP. My last memory of a VAG diesel was over ten years ago with a but I'd hope with ten years of progress and two extra cylinders they would be more refined now?Would love to be looking at the S6, but the thought of a repair bill on that Lambo V10 sadly rules it then as an over budget choice, what's the new 2011 C7 model like? Looks to have the same engines as the C6 facelift, and a quick look on Audi Approved Used shows 72 S-Line Avant's with the TDI (240PS V6) and some people seem to have actually bought the petrol this time as there's 3 with the TFSI (300PS, V6 Supercharged)... both starting at £29K. But it's over the ideal budget, and is it really £10K+ better than a late C6 facelift one? There was a thread in this section a few weeks back on someone who'd run a C6 litre petrol so might be worth going back a few pages... If you don't do much mileage I'd always go petrol.

If you don't do much mileage I'd always go will have a look for that thread. But much as I'd agree with you re petrol, I can't find a single one on Audi Approved Used or Autotrader, and only one here on Pistonheads... so where are they!? Saturday 20th July 2013 Saturday 20th July 2013 We bought our 2008 Le Mans Avant as an Approved Used a year ago. I'd have preferred a petrol, but there just weren't any in budget at an Audi dealer. The diesel is a smooth V6 and will see 40 on a run even with a car load of people and luggage, nothing like a 4 pot dag dag Saturday 20th July 2013 I bought my LeMans new in 2007. Averages 36mpg and gets to 41mpg on a run or 42 with aircon off. Its plenty quick enough and pretty refined, but will never be as silky smooth as a I was buying again though, I would get a diesel, we also run a petrol Subaru Outback and road tax plus fuel cost (average 26mpg) feels painful in comparison. Original Poster 98 posts 190 months Sunday 21st July 2013 Thanks guys;I'm still at a loss why I cant see many TFSi (petrol) Avants at dealers. Can see plenty of TDI'sThoughts? Sunday 21st July 2013 Because people are sheep and the diesel is always cheaper mentality hence they havent sold many. I picked up an absolute bargain A5 last year just because it was a petrol. At the time it was the only one of its type on the Audi used car website... But was £5k less than same age equivalent spec'd 2 litre models. IainT 10,040 posts 217 months Sunday 21st July 2013 I've just recently got hold of a 2012 facelift A5 TDI and the engine is, for a diesel, a real gem. The in our TT sounds nicer though!A quick nose on the various forums show a lot of relatively cheap tuning flexibility too for the diesel engine turning it into a 300PS/600NM beastie. Not something mine will be seeing while it's in warranty though! Gio G 2,827 posts 188 months Monday 22nd July 2013 If you want something different, go for the If you can find one that is. Audi had a whole stock of these cars in that unusual blue colour (forget the name)doing great deals, which I purchased. I suspect that quite a few of them will be coming up to 3/4 years old on the used you asked a dealer on a deal for the new I bet they have some amazing deals if you PCP with massive contribution deposits, as no doubt the default is always the engine, therefore incentives for the petrol are usually very good. Kell 1,708 posts 187 months Monday 22nd July 2013 Unfortunately, I never got the chance to drive a but about six years ago, when we were first looking at an A6, we drove the V6 petrol back to back with the the diesel won hands down in my test. The petrol felt like the handbrake was on in comparison. In the end we just couldn't afford either and got a BMW 530d MSport. Which was the worst decision we ever made, but that's by the my mindset was always that the diesel was the better all-rounder. But when we bought our A6 in October last year, I did ask the same question. The Official Audi figures aren't that far apart between the and the but in reality the diesel figure is a little optimistic, whereas the petrol one seems to be pure said all that, I wonder whether we made the right decision. In my experience, big diesels don't get good mpg around town. Certainly, if I'm in a hurry to get to the station, then 17mpg is not unheard of - and that's indicated, so who knows what the actual is?Our justification for diesel has always been the fact that my parents are 300 miles away, and my in-laws are 200 miles away, but in reality, we only make those journeys four of five times a year, so the extra fuel would probably be covered by the cheaper purchase way, you'll get a good car, it's just that the seem to be as rare as rocking horse poo.

I don't have an overly light I ever get is late spring run to the station 14 miles and if I am really gentle average 38mpg on the journey. Its when its really cold in the winter with lights, heated seats, heated screen, heated mirrors, cold oil etc thats when it gets down to low 20'mpg. If I drive a couple of miles further the average shoots back up to about 34. It just seems that the 12 miles is too short for it to warm up properly IainT 10,040 posts 217 months Monday 22nd July 2013 blueg33 said: If I drive a couple of miles further the average shoots back up to about 34. It just seems that the 12 miles is too short for it to warm up properlyI guess that makes a lot of sense really - a lot of extra load on the system. A bit like the nice readout showing just how much juice the aircon is sucking (so far I saw it peak out at 2mpg usage), mostly it runs at ~1/8th mpg...My run to work is just under 30 mins with the first 15 being slower 30/40 plus town centre. Should be warmed up by the time I get onto open roads which is probably why I see better numbers. We'll see what winter brings. Wednesday 31st July 2013 I must admit i'm also going through this dilema petrol v Derv avant currently. I already own an older C5 pterol V6 avant due to be changed this year & last week we toured the South West for a week & averaged 33mpg with some heavy right footing on the motorway & inclines, fully loaded with aircon full etc etc - not badMy new 07 company Passat Derv used to struggle to exceed high 30's on a 4 cylinder unit, when equally our A4 Petrol 220hp driven in anger returns low 40's high 30's on most tanks. So are Derv's actually that efficient when balanced against higher purchase price & rougher running & minimal fuel benefits - i am tempted with a TDi but i'm not convinced of the benefits for a petrol head.

I'm continually surprised by how swift our A6 is - so much so that I think the brakes aren't really up to the think it's mostly going to come down to the types of journey you make rather than the total number of of short journeys - probably mentioned above, and echoed by other people, I regularly see sub 20mpg on my 2 mile commute to the station, but then equally I see 38 to around 42 on motorways.

The seller claims there's never been any problems with either the injectors not the hydraulic chain tensioner and this problem started suddenly after he stopped to get diesel. He claims it's the hydraulic valve tappets making the noise, but for me this knocking sound is different than "playing" tappets. Please have a look at the short video: As we can see, the car is quite heavily smoking off the exhaust too, meaning that most surely the injectors need replacing - but my main concern is the loud knocking coming for the engine. It doesn't sound like a problem with the timing-chains / tensionser, I'm a bit worried it could be a connecting rod bearing or one of the main bearings that spun around (perhaps due to fuel delivery issues)? If someone would have any idea (or know) what this could be (or what to check/where to look to confirm) and the estimate costs involved in a repair, I'd much appreciate a helping hand. Many thanks for your attention and wishing all the best, ericsson #2 Welcome! OMG mate! This did not sound any near like an A6 More like a tractor and it's smoking like one also. I wouldn't know much to help you on that but it will be good to start with an VCDS scan. This can possibly exclude few issues like injectors. #3 Hello Kris and thanks for the welcoming Yup, I know it sounds horrible (and serious), that's why I'm trying my best a determining the cause of these noises. Obviously the injectors are gone, but that's a much smaller issue than the loud, knocking sound the engine is making. I'll try to do make another video today, as I'm scheduled to view the car this evening. Unfortunately at this moment there's no way for my to dy a VCDS scan due to not having any equipment - so all I can do is touch, see and listen. I'll try to rev the engine a bit higher than it's idle speed to see what's the reaction and does that help/chance the noise in any way. Perhaps this will help to try saying what might be the cause. I'd like to ask would anyone be able to advise on what to check, where to listen closely in order to either exclude or track a faulty sector of the engine?
