I had the same problem with my Audi a4 its an oil consumption problem well know by audi take it to the nearest Audi dealership repair shop right away because it is cause unnecessary wear and tear on your vehicle and next thing you know you're going to end up having major engine problems and its going to be a very costly repairand if you bought the car previously owned that person didn't pay attention to how much oil and so its like driving a car without changing the oil and they should be able to fix the problem for free through Audi tell them you want an oil consumption test done

Hi mike, I have the same problem. 2009, A4 1.8T. Almost 1litre oil consumption @500-600 km. In our country dealer asked 3000 euro to fix problem. Is it possible to learn from your dealer what they did to fix problem?

Hi, they recognised the manufacturing default and changed the pistons. The cost was 3000 euros for the parts amd 1000 for labour. I paid only the labour.

I've got an a4 1.8T 160 And its drinking lots of oil and chucking out blue smoke. I've been told by audi dealership the Pistons and com rods have failed and it will cost £4.5k. They are waiting to hear back from audi HQ if they will contribute but as one of my services wasn't at a main dealer they may not. The car is only 5 years old with 70k. I've already had a failed turbo, fuel pump, fuel pump sensor and water pump all fail in the last 2 years since manufacturers warranty expired.

Got the same issue with my 2010 A4 estate 1.8 TFSI - drinking around 1l of oil every 300miles, no smoke tho. Booked visit in local Audi dealer for next Saturday. I'll let you know what is going on and what are the costs.

I'm having the same issue with a used car I bought 6 months ago. it's an A4 1.8 turbo. It's booked in for an oil consumption test next week, but after reading these posts, I'm really worried about the potential of a £4K bill.

Does the same oil consuming issue occurres in Audi A4t 2011 as well ?

Oil burning is present in an Audi A4 1.8 T 2012 S Tronic (DSG, that is dual shift gear). According to the manufacturer, burning oil is normal (because it has a turbo) and will depend on the driving conditions (how you drive and if you use the S mode will burn more), geography and temperature. My car (the one mentioned above) burnt almost one liter (a quart) of Castrol Edge 5W 30 in just 200 kilometers (in the S mode). I recently changed the oil (Motul 8100, 5 W30). I drove around 250 kilometers and apparently it burnt less oil. I have to wait more time in order to verify if changing the oil brand helps to reduce the problem.

High oil consumption on Audio A 1.8T. Took it to the Audi dealer in Springs SA. They topped up the oil and told me to return after 1000 km or when oil bar indicator is at lowest point whichever comes first. Upon return they checked and told me what I already knew. That oil consumption is high averaging around 1 litre per 500 km. They then gave me a written quotation amounting to R284k. My spark plugs are as dry as always and there's no oil leaks. The car has not lost any power. Performance is good but my tail pipe is pitch black. I doubt if these guys in Springs know what the problem is or they just don't give a darn. I have been driving the audi brand since 1990 and now my loyalty is divided.
