P0089 Check engine light code

[SPONGE]

Has anyone else got this code on their 3.0t?
What did you replace to cure the code.

Thanks in advance,

Doing a quick google search on this code reveals it is for the fuel pressure regulator. I would take it to the dealer and get an estimate from them to correct the problem, assuming you are no longer under warranty.

I think there's a TSB on the high pressure fuel pump for the 3.0T 2013 models.

I just got it today. 2013 A6 just hit 30,000 miles.

Did your car experience any kind of fuel cut when it happened? Did you take it to the mechanic and what did they say?

Nothing so far, I checked the code w/ the torque app on a tablet I have, and cleared it. I've driven 100 miles so far, the only thing not to "ready" yet is the evap. Going to wait for everything to ready up and see if the code stays cleared. If it comes back I'll run it by the shop and have them check it out.

I understand if you're tuned and you don't want to get it fixed by them but if you're under warranty why not just take it in to a dealership.

I'm out of warranty but I called the dealership and found out that there is a recall on the fuel line. Call and provide them with your VIN number and see if yours have been identified. Taking the car there Monday and I will report back if it resolved my issue.

Good Luck and Happy holidays

That's I took it back to the tuner shop for diagnostic but a call to the dealership discovered a recall for the fuel line which will hopefully resolve my intermittent issues.

Did this resolve your issue?

[SPONGE]

The recall did not clear the code. I ended up changing more parts at one time to save on labor and give peace of mind.
I changed everything related to the code.
there was a Recall for intank LPFP (filter and lines) for my car.
Bought two fuel sensors.
Cam Follower.
HPFP.

No more code. No more issues.

Did this happen after or prior to stage 2?

Also, anyone else read up on the oem flex fuel lpfp audi has? Seems some S4 guys use it and was wondering if it would be a solution for additonal fueling.

[SPONGE]

several months after going stage 2. (around 5 months.)
I'm not running a E85 tune (which requires the upgraded HPFP)
Also the code can back when I returned the car to stock programming.

But the parts detailed above fixed my problem. 2 weeks free of issue and counting.
