My 2011 A5 2.0T was eating 1 Litre of oil every 150 Kilometers (had to buy 1L of oil every every 2 days). Plumes of smoke would come out of the exhaust after about half an hour of driving (I guess the cat was burning off the oil).
Odometer was 95000km
Brought the car back to the Audi Dealer where I bought it from 3 years ago (2nd hand) and it went through the usual tests, and failed miserably.

They ended up replacing the pistons, piston rings, engine block (cylinders were scored too much), and some other parts. They said the total repair was around $16000 but Audi Australia said they will cover most of the cost, I ended up paying around $4000.

Its been fine since then. The oil light hasn't come on for 8 months..
How long had it been burning oil for? Did you ask them to cover more of the cost?

It just all of a sudden started going through that much?!
Since I bought the car it had always used more oil than my previous cars but the dealer said it was normal for Audi's when I purchased it. I was refilling the oil every 2 months or so but then it got worse and worse, where I was refilling once a fortnight.
Then one day the engine was cutting out due to the spark plugs being worn out and having lots of oil on them, so I got a mechanic to fix it. He was rough with the engine when he was diagnosing the ignition problem (he was running it full throttle when it was stationary with spark plugs removed), and then it started drinking 1L of oil every 2 days after that.. which is when I brought it into the dealer to do the consumption tests.

A5 Convertible Oil Consumption

Hi guys, just reading the following pages relating to what is clearly a well known and widespread issue.

I have a January 2011 A5 1.8TFSI S Line Convertible which was purchased in June 2016 with 47k on the clock. Audi demonstrator +1 Lady owner from new. Part Audi service history, but the car was purchased from an audi specialist who had serviced the car up until 46k.

The issues started 5 weeks into ownership with the car burning around 1L oil every 300-400 miles. I contacted the independent dealer who advised me that the car would be looked at as this was a known issue. The car was booked into Belfast Audi in August for the initial investigations, and sure enough failed the consumption tests...the remedy...new Pistons and Con Rods. After supplying Belfast Audi with the relevant service paperwork, the work was carried out FOC and I received my car back end September 2016.

All seemed fine for a little while, or so I thought until I noticed that I was having to top up with oil again despite the car having been serviced in the interim using the correct AUDI spec oil and filters. I did notice the car was becoming slightly harder to start, but put this down to the cold weather.

June 2018 and the car was serviced again and the correct Engine Oil and Filters, and all seemed ok. Then the problems of Oil Consumption seemed to rear their ugly head again. From June-December 2018 I found myself having topped up 7L of Oil, which I became concerned about. I contacted Belfast Audi, whos response was "its nothing to worry about, the remedial work was done so you will have no further issues". The car broke down just after Christmas, and was towed by the AA (who suspected coil pack- car off a cylinder) to my local mechanic, who changed the spark plugs and coil pack - no difference. Worryingly, my mechanic has pointed the pistons as the problem yet again.

I contacted Belfast Audi, who immediately told me to bring the car back to them and they would investigate. Having explained the situation and worry of a hefty bill I was told by their service manager "not to worry, he would help and get me sorted out ok".

The car was recovered on the back of a truck to Belfast Audi who have now had the A5 for over 2 weeks. Current mileage 82k. I received a phonecall from the service manager 8 days ago informing me that there was a hole in the cylinder, and the car needs an engine and a turbo :surprise: He told me that he was contacting Audi to seek a claim for both parts, and he would work on whatever was remaining from any goodwill Audi would provide. I am worried that because I received the Stage 2 Piston repair FOC they will now renage and ask for a contribution. I am extremely disappointed that in just over 2 years and less than 30k the same problem has re-occurred after Audi re-built the engine.

Although I'm in a Q3 loaner I am missing my A5 and am quite anxious as to how long I should wait for a response.

Has anyone else been in a similar situation?

Thanks

An update, took my 2010 A4 to Audi Bromley after Alan Day VW tests after tests and giving me all the BS. Audi Bromley knows straight away what the problem was as soon as I explain what was wrong with my car and Wayne Turner a very friendly fella explain to me the process of the oil consumption tests. As expected my car failed stage 1 and so they did the piston mod on my car free of charge with a coutesy car because I have a full service history. So far everything is good about 50 plus miles oil still on max and I will keep on monitoring. Big thanks to Audi Bromley all staff there are very polite and friendly. Wayne Turner thank you very much for all your help and to Kerry of Audi UK.

1.8TFSI Convertible Engine replacement after stage 2

Hi guys, new to all of this but having read the comments, It is clear i am not alone. Sorry for the length of the rant below :

In June 2016 I bought a December 2010 Audi A5 1.8TFSI S Line convertible from an independent Audi specialist (Jack Reid Cars) here in NI. The car had jusr under 55k on the clock, and had a full service history (non main dealer). The car was financed for 5 years and came with 6 month warranty

2 months later the car was drinking 1L Oil every 350 miles or so. Phoned jack reid, was booked into Belfast Audi for the test, and duly failed. The car went back into Belfast Audi in September 2016 and Stage 2 Pistons and Con Rods were deemed necessary, the repair being carried out at no cost to myself. I was told at this point by Belfast Audi that the repair meant the problem had been permanently fixed, would not reoccur and I would have no further issues witih the oil consumption.

Fast Forward to Summer 2018 and I found myself putting oil in the car more and more often again. 7L Of oil was added from July-December. I phoned Belfast Audi who told me that as I'd had the fix before, this was nothing to worry about as the car was driving fine (which it was - minus up on fuel consumption and becoming a little harder to start)

January 2019 and the car suddenly broke down without warning. I pulled in, phoned the AA who sent their partner company out with a code reader. He suspeceted the car off a cylinder, and I needed a coil pack. The following day the car was towed to our independent mechanic, who replaced spark plugs and coil pack..no change.

After further investigation he discovered that the oil was penetrating through the pistons yet again, down into one of the cylinders - another one on its way out.

After taking advice I telephoned Belfast Audi, speaking with their service manager whom I had dealt with before. His immediate reply was that the car needed to be "brought back in" and they would "sort me out". I advised that I was extremely unhappy that my car was back in with the same problem 2.5years after having had the PERMANENT FIX at Belfast Audi. I also advised them that I wasnt prepared to bring the car in if faced with a large bill, but I was told again my him "We will get you sorted, dont worry. i have a friend who was in a similar position". He told me not to contact Audi UK as they could be tetchy about it, let him contact them if needed.

Belfast Audi recovered the car from our mechanic on Friday 25th January, and provided me with a loaner Q3. I was told to await a phonecall whilst they looked at the car, but not to panic. The following Thursday (31st January) I received a phonecall from the service manager in Belfast Audi, who told me that the car needed an engine AND a turbo, and he was submitting a claim to Audi UK for the cost of these repairs. At this point I advised that I was extremely unhappy that my car was back in with the same problem 2.5years after having had the PERMANENT FIX at Belfast Audi. I was told not to worry, and that if they came back looking a contribution he would have to see how he would write back any remainder. He told me to leave it with them, they would deal directly with Audi UK and contact me ASAP.

Fast forward 4 weeks, and Belfast Audi finally telephoned me yesterday to say that Audi UK finally came back offering to contribute towards the repair, however I was required to pay £4,000 myself. No reason was given, and when I asked as to why this was the case I received a generic response of "dealt with on a case by case basis by Audi UK". She told me that Audi UK were not prepared to contribute anything and wanted 100%, however she went back and forward back and forwardo to negotiate it to 40% contribuation from myself. No reason as to why 40%, however surely when Audi UK told the dealer they were not contributing anything towards the repair the dealer would not be trying to negotiate unless they thought there was an issue/case to answer? Especially since the Stage 2 repair was carried out by the dealer 2.5 years prior.

I told the service advisor I was unhappy with this offer, as others on here with the same issue received a full replacement FOC from Audi UK. Was this discrimination on my case when others were getting the work done so widely for free. The fact that Stage 2 was carried out prior and didnt fix adds insult to injury, and as a result of the repair not being adequate my car now needs an engine and is worthless.

At this point, she told me that she would have to speak to the service manager and get his take, and come back to me. I am very disappointed that It has taken 4 weeks to reach this point. I'm now left with a massive headache, and a monthly payment on a car that is virtually worthless.

Also in NZ

Update from AudiNZ, failed using 0.84l/1000km. So new new pistons etc coming my way! Just getting further info on what else they will need to change, have been told that carbon cleaning may be done as my head will need dismantling. Was going to get water pump, DV, and PCV all done at the same time.
Hi. I'm in NZ. Did you have to pay for the repair? I've got a 2012 A5 with the oil consumption issue.

So I bought a 2010 last year with 70k miles on the odo. They said they had some "transmission" work to be done on it. I did some research but read about this consumption issue until recently. For a couple months I was worried, but my oil gauge never once went down. I'm at 80.5k now. In doing some more research I stopped by the dealership and asked if they could tell me about any recall work that had been done on the car. They told me 8 alignments and "phase3" of the consumption fix. I've read in here that means a new (to the car) engine due to scoring of the cylinders.

How can I verify visually if that's true? Would there be something identifying it on the engine?

Thanks for all the great info.

Hi guys, I bought a 2009 2.0 Tfsi A5 in September in lovely condition but unfortunately didn't come across this thread until I was looking for the best oil to put in it. I noticed it was using significant amounts of oil and when i brought this up at Bolton Audi when i took it for a service i was firmly told this was normal.

I immediately contacted Audi UK and got a call back and had the whole test procedure explained to me and to just call a centre and book it in.

Having lost faith in Bolton I booked the car in at Oldham Audi. Who did stage 1 gave me the car back, I did the required mileage and took it back.
I was told the car had tested to be in spec and i was given a pro forma invoice stating the car had used 0.531 litres per 1000 miles.
I tried to get an answer at to why this was miles when the test was done in kms and I was fobbed off.
I took this back up with Audi UK who looked into it and said there had been a mistake the paperwork should read kms but the car had still fallen within spec.
It's my understanding that if it used over half a litre in the allotted mileage then it failed.

I'm still trying to get a copy of the reports and corrected paperwork so I can argue my case but it's been a painfully slow process. Audi UK have said I can get it tested elsewhere but my 2 most local dealers I've lost faith in, 1 mislead me totally and basically lied to me and the next made the simplest of mistakes which left me wondering what else they got wrong.

After I got back from being told the car was in spec the oil level was the same as when i gave it to them, i measured over 650 ml of oil into the car and it still wasn't full on the gauge.

Can anyone recommend a dealer in the northwest who I can go to and put my faith in.

Hi first post for me.
I have just bought a 2012 A5 2.0 TFSI with a CDNC engine, is this likely to be affected? The posts mention a 2012 cut off, mine was manufactured November 2012.

You’re probably fine, mate. Your build date puts you one year on from when the changes to kill the problem were implemented. Relax, and enjoy the car.

I have to say this thread as hugely put me off buying a A5 fsi engine. It seems it's prevelant on all petrol engines, I was looking at 3.2 L petrol but won't bother now,it's a diesel or save a little more and buy 2012 face lift petrol car.

Hi everyone,
I'm thinking to buy A6 2.0 TFSI 180 hp MY 2011. Owner said there is no oil consumption. Is it true? Does it have oil consumption problem? Should I buy it or avoid?
It is on 99.000 km.

Owner said there is no oil consumption.
could be true.
but he would never sell it, if he said there is a serious problem.

Does it have oil consumption problem?
but it will probably get the problem in due course.
