This is why your Audi throws the ‘Add oil max 1 qt oil’ message - from an Audi specialist

[@ChelseaMiddlebrook]

Thank you for this video! This has been happening with my Q5, 2013 every 900-1200 miles!

Get whose piston rings replaced! They will score the cylinder sleeves and ruin the engine.

[@pascha992]

Thanks a lot for the video. Very helpful. Did you detect issues on pistons by running compression test? Or do you think issue with pistons that you show can be detected by compression test?

[@carhavneurotech]

Great q. Compression testing does not effectively detect piston ring failure. Endoscope is the way to go.

[@macannnas]

Hi there great content... I'm. In the middle of engine rebuild... Would you share with me what kind of rings do you recommend..? Thank you 🙏

[@carhavneurotech]

Sure! Only OEM or Rhinmetall ( they make them for Audi)

[@carhavneurotech]

The design has been updated.

I may need this on my ‘15 A4. But I hope not. May I ask the cost at the end of the day? I’m sitting down.

[@carhavneurotech]

lol. The cost of the job depends on many factors. In our 20 years of experience the number one lesson is to never quote a job without diagnosing the issue first. Reach out if you are in CT, we'll be glad to help.

Where you buy pistons?😀😀

[@carhavneurotech]

Truthfully our local dealer. Lately we have had luck with eBay - they have kits from Asia with excellent original parts for a great price.

Do bad rings give any issues like check engine lights ? Im having a (turn engine off add oil light) but i don’t have any wet areas in pistons. I did valve seals already. Cars throwing blue smoke. Not sure if its burning off old oil in internals from previous owner. he had put 10 quarts because the light keeps saying low oil.

[@MiguelSanchez-rb3tw]

Just hoping its not piston rings. Car drives great. No engine codes or pending.

[@carhavneurotech]

They won't cause a CEL, nor will they throw codes as there's no sensor to measure them. It's the 'add max 1 qt of oil' or similar that should prompt you to have them inspected by a Euro specialist.

[@laurawilliams9338]

@@carhavneurotechour Audi service dept is AWFUL. I’ll google Euro specialist. Great info!

[@aribeep4007]

Did the cylinders needed honing?

[@carhavneurotech]

Thankfully no! In our experience, if there's scoring in the cylinder walls it's time for a new engine. The materials used in the walls are too delicate to hone properly.

How much is the cost for this job?

[@carhavneurotech]

Pretty up there. See your local Euro shop for accurate pricing.
