Hi guys
So my S4 has 110k now , got it at 100k . So for the past year i had no issues with oil , my next oil change is in 7000k according to the MMi. So around 3-4 weeks ago i was looking around in the car setup ( don't remember why) and i came across oil level , i looked at it and saw it was half way . Told myself no big deal lets see how it goes .
So last week i'm driving around and the low oil light comes on telling me i need a L. Ok fine i drop at audi and feed her 1 L. Today , so about a week and 300km later i look at the oil level and it's a bit below half . SO she drank 500ml in 300k .
Looking around the interwebs it seems audi changes the piston rings for something this excessive . I also saw there was a TSB for 2010-2012 S4's for PCV valve followed by a ecm update .

Nature of Defect: ELECTRICAL SYSTEM: SOFTWARE
Bulletin Number: TSB-01-12-58

SUMMARY: AUDI: WHILE DRIVING, MAINLY SHORT DISTANCE (STOP AND GO), HIGH CRANKCASE PRESSURE CAN LEAD TO DTCS P113700 AND P113900 CODES. CRANKCASE PRESSURE CAN BE LOWERED WITH NEW ECM (ENGINE CONTROL MODULE) SOFTWARE LEVEL AFTER CHANGING CRANKCASE PRESSURE VALVE TO IMPROVE AND ELIMINATE MENTIONED DTC CODES.

AUDI S4 2010-2012
AUDI S5 2010-2012
Reason i'm thinking about this TSB is because in the past 2 weeks i have been using my car a lot more than usual and been doing lots of stop and go.
The TSB also mentions fixing issues related so some DTCS codes .Does this mean if i don't have those codes this TSB does not apply to me ?
So i figured i would ask around the audi dealers see if they can inform me a bit more on that fix and who ever answered me at ddo is a french prick didn't care about what i was saying just wanted me to bring the car in to inspect , Lauzon was a chick and she kept talking to me about warranty which i don't care about i just wanna know about this tsb , she says it doesn't apply to my car, asked audi prestige and the rep there seemed to have found the TSB i was referring to and quote me around 1k for install of pcv and ecu flash. It's crazy i expected audi service to be nice and helpful but they seem stressed as fuck and very rude.
An answer i have not being able to find out is could i get the PCV installed myself and then simply ask audi to update the ECU ? what king of update is it , is it simply flashing my ecu to the latest firmware or is do they need to tune it to reduce the pressure in the crankcase .
If it's my piston rings that require to be changed , say i was to not fix it and simply add oil when i need to , is there any damage that can happen to the engine ?
Any help and information from you guys would be appreciated
