Just a question here. When you last checked the oil was it still full. I assume you check the oil weekly?

 

Yes I keep monitoring the level using the in car system it's getting to the lower one quarter of the Gauge I'm going to change oil this weekend but big improvement over using a quart every 800 miles

 

OK so I'm trying to understand the logic here. Why would you not top off the oil if you see it down a quarter of a quart. It seems like you are waiting until it goes down a quart before you top it or change it. Also at what mileage interval do you change the oil.

 

yeah, they already did all that and still my timing chain was stretched, I can only surmise it was due to lack of lubrication, and I cant get past the fact that if it wasnt for a fault in design I wouldnt actually be going through this mess. Why is it at the consumers expense when these issues should have just been recalled, I just thought Audi was different.

Sgt I'm with you here and being a shade tree mechanic starting back in 1960 and having worked as a ME in the semiconductor industry since 1966 I fine it hard to believe there is not both a design issue and a QC issue here. I don't think the dealer service know the root cause but are only told to do the testing and replace parts. I also don't think Audi will ever publish the cause as it will expose some of their questionable manufacturing processes. So in the mean time they are at least trying to fix the problem but at some point they will stop and those who buy a problem car will have to foot the bill themselves. Time will tell. Good luck on your fix and keep us posted if it starts to use oil again.[/QUOTE]

Jag, the beat goes on. And hopefully most have seen the Consumer's report on BMW, Audi, and Subaru. Top 3 "oil eaters" and I have both (A4 and an 09 Forester).
I maintain a weekly check on mine, both vehicles. I opted for an "oil dipstick" as well and use it with more faith than the MMI. Not sure if I told you folks but they put a new turbo in the A4 as well as the pistons, rings, etc. Just a little bit of a gear head / tech here but knowing how the turbo works, realizing there's an oil consumption problem, and that waste gate is handling oil at somewhere around 400 degrees Faren. Seems related to me. I am not familiar with the oil pump system on the 2.0 T but I would think that would be suspect as well...just sayin'.
OK, timing belts and chains; believe it or not I have not looked at Audi's prescribed need for a new belt/change in the Owner's Manual but if it says 75,000 then it will be changed at 74,900 because I don't want pistons slamming against valves. Those that don't follow the recommendation...oh well.
As I reported previously I could not, repeat could not...get any corp engineer or QAE on the line to explain the root cause of the ring/piston problem and I knew that going in but decided to pursue it just because.
So far almost 2K on the "new" pistons and no oil use.

In late 2008 Audi changed from timing belt to timing chain on the 2.0L engine. If you have the engine with the top oil filter it is a chain drive system. No early maintenance.

 

"After stage 2 'oc" is it possible the other parts are effected after say 65k mi? My pistons, rings, etc were replaced 35k mi ago, only to have my motor blown by a stretched timing chain"

Hey trees, I may have missed it but at what mileage did you chain go "bang"?

Had you ever had that changed previouly (if you have high mileage)?

That's one thing I'd never ignore; timing belts and chains.

Oil consumption; I dunno! I think I made my comment(s) previously about having a very similar problem with my Harley. I ended up sending photos of 3 sets of spark plugs to the CEO in Milwaukee and finally got the problem resovled. Root cause: base material on the valve stem seals was bad...the seals were "going umbrella" ie...turning inside out. HD had since changed the base material on the seals. Glad I kept all of my communication and photos (actual plugs too).

Good luck bubba.

Can you believe I haven't removed that plastic canopy (engine) on the A4?

Filter? In fact I'm gonna' go and look. Yep it's on top. I came up with a gimmick to use on my HD to capture the oil when I removed the oil filter (mounted in front, horizontal. Duct tape is amazing! Almost better than garbage bags!

Seeing as many belts are used do you know why Audi went to the chain?

Sgt Steve

 

The plastic cover just pulls off as it has a few rubber plugs that hold it on. The filter is on the front right top and is a black round can. It is an anti-back flow filter and you can just unscrew it and no oil will come out. I change the oil using an oil extractor (vacuum) where you stick a tube down the dip stick hole and suck out the oil No mess oil change. As to a chain vs belt , the chain will last 2-3 times longer then a belt. It is less likely to break and it has a chain hydraulic tension-er . With an interference valve motor a chain is a safer design.

 

I own a 2009 A6 with a 3.0T supercharged engine and I'm having consistent Oil Consumption issues. Just as others have posted I'm adding at least 1 qt of oil every 1000 miles. I ride around with a 5 gallon container of synthetic oil in my trunk. I have 111000 miles on the car... It runs great but not sure what damage is being done to the engine... Is this something I should just live with? or is it time to trade it in for a BMW???
