I might be interested....is it the banjo bolt style?

No banjo. It's just sitting in a box with some ther stuff. Pm me if you ever want it- just pay for shipping

Damn P0089 came back on again today, not seen it for a while. Started my car at lunchtime, CEL on, driving fine, scanned it when I got home and sure enough P0089. It's been about 20k since I last checked my cam follower, so I will give that a check (most likely replace it while I am in there) and also put in a new fuel filter.

This has to be one of the most annoying codes though, no real solution for it except replacing parts and hoping!

Yep, I'm still getting mine. Have had it for about 2 months. I have cleared it multiple times, and it has gone away on its ow BBC a couple times, but it keeps coming back. The weird thing is that it only seems to come on during either start up or idling.

I have Jhad's used hpfp just waiting to get swapped in, but its not the banjo bolt style, and I need to figure out what is best to swap it in.

^ all you have to do is swap the brass fitting (for the banjo bolt) from your old pump to the new one.

Nope, there's also two holes on the side where the thrust sensor screws in, so I either need to figure out what part I need for the bleeder valve, or swap that side as well.

Jim- i think ECS offers a conversion kit. I cant remember if it is ECS or another vendor, but there is a solution for you. If I have time at work today, I will look it up.

**clemsongt** · 03-06-2013 10:27 AM

Has anyone replaced anything related to the EVAP system (such as the charcoal canister) and experienced the code not returning?

Hmmm, negative. Although I do need to do that....

Lucky this thread is still up and running.
Let me first say that Audi of Silver Spring is awesome. They cleaned my car inside and out and changed out my cam follower and associated parts with no troubles at all.

Now the dreaded P0089 code popped up again. I know its not the cam because it was changed not even a week ago. The car runs fine with the fuel rail reading min of 700psi in the Torque app. The code was cleared last night but came back again tonight. Its weird that it only comes on right when I start it after work.
Any ideas on what I should look at? Should i disconnect the battery?

Also, the new HPFP looks completely different. It has an extra thread hole with no input.

Edit: So this is the pump that was put in http://www.ecstuning.com/Audi-B7_A4-...5_K/ES1304269/
Where is the low pressure fuel sensor?

**Jhad** · 03-13-2013 08:13 PM

The thrust sensor does not come with the pump. Most likely they just removed the sensor from your old pump and installed it on the new one (it happened to me). I would buy a new one. Here is the part number http://www.ecstuning.com/Audi-B7_A4-...nsor/ES251666/

**pkny** · 03-13-2013 08:18 PM

Thanks, jhad.
Do you think this is i am getting the dreaded P0089 code?

**naiku** · 03-14-2013 03:44 AM

Does anyone else who gets this code notice the fuel pump priming longer when opening the drivers door? My code is off again, but something I had noticed was the priming behaviour changed before the code came on. When I leave for work today I will pay attention to see if it still primes longer, or is back to normal.

Edit: Stupid code came back on again, started the engine up fine, no code, looked down as backing out of the garage, CEL on again. I have not yet scanned it, but I am fairly sure its the same code. This morning my fuel pump did not prime when I opened the door, however I had opened it last night and it primed, but I did not drive anywhere. I did hear it prime while turning the key though.

**jimrobbington** · 03-14-2013 07:53 PM

My p0089 cel only comes on during idle, or start up. I have never seen it come on while driving. It looks like this is common between us all on this page.

I have 145 bar prv, upgraded lpfp, swapped thrust sensor too. Will be swapping the hpfp soon to see if that changes anything.

**clemsongt** · 03-19-2013 08:56 AM

I actually came here to ask if everyone else experienced their P0089 coming on at startup and guess that seems to be the case. Mine does not always come on at startup, but when it does come on it is on a startup or within 20 seconds of startup. It is always a cold startup, but not all cold startups. I have not figured out a pattern other than it is most frequent after work around 4-5 pm. It does not seem to be temperature related as it does it on 70+ degree days or 40 degree days.

Just to keep all my info in one place:
New G410, follower with 30k recently inspected, new LPFP, new fuel filter.

Most likely unrelated but potentially related as it is a fuel issue:
I do have some issues with the EVAP system - the fumes escape only back up through the neck causing the pump to shut off while fueling unless I have the nozzle slightly out and only the slowest pump setting.

**80sGuy** · 03-19-2013 09:10 AM

I know some of you guys are having a ball chasing this P0089 code, but if checking/replacing stuffs like the G410 Thrust Sensor, Pressure Fuel Pump, etc., etc., still doesn't help....and since it is fuel-related; maybe it's about time to check out the Oxygen Sensors.

Care to elaborate as to how they could be the culprit? This is just me thinking out loud: If the O2 sensors were bad and the car running well, they would send the wrong voltage to the ECU which would then throw a code for too lean or too rich. If the air in the exhaust is too rich or lean and the sensors are bad but telling the car it is okay, then it would not send a code for too rich or lean (as I don't have and suspect others also do not have), but would mean something else is malfunctioning.

So I cannot determine how the O2 sensors are the culprit, either they are bad and it would come to light when the P0089 is fixed or I'm missing something?

**80sGuy** · 03-19-2013 02:16 PM

^^Error codes are not specific to the 'problem' or culprit, but a start. Some (like me) tackled the issue by replacing only the G410 and never saw the code again, some have replaced something within the region, and a few others did something else. Like I mentioned, when all else fails, it doesn't hurt to check the O2 sensors, or maybe clean the MAF.

I understand they are where you start, but in diagnostics you start with an assumption and make logical conclusions from there. I started with "maybe O2 sensors are bad" and couldn't deduce why the P0089 would be caused by bad O2 sensors. I don't want to sound like a jerk, but if you can't tell me why they might be bad or present the symptoms we are experiencing (ie: P0089 code upon cold startup) then I have no choice but to ignore the advice. I'm not going to spend money on a blind hunt of replacing random parts.

Thanks

**80sGuy** · 03-20-2013 09:26 AM

^^Excuse me, don't want to sound like a mf a-hole but....I'm not the one who started this whole P0089 issue suggesting with the O2 sensors. I also got this code almost two years ago and the first thing I looked into was the fuel system, (Thrust Sensor, Fuel Rail, etc..) and replaced the G410 -- code hasn't come back since. I'm just advising to look further since you're going in circles trying to figure out why you're being plagued by this code. I said if all else fails, it doesn't hurt to broaden up your research and hunt a bit out of the area, perhaps 'check' your O2 sensor. I'm not telling you to replace random parts, all I'm saying is (if you read my post correctly) is to "check out the Oxygen Sensors". You have the choice to either take it or leave it instead of backfiring over what make sense and what not. Let me tell you this; the P0089 code does NOT make any sense at all. You can spend the rest of your life trying to figure out this CEL for as long as you owned your B7.
Good luck!

... Add me to the list... :( Just threw P0089. CEL came on when WOT on the entrance ramp of the hwy. I've read through this thread and at this point am a bit confused on what is need to fix the issue. Current running APR stage 1 91 octane setting. No other mods.

G410 - 06E 906 051K?

Check Cam?

O2 Sensor?

Can anyone shed a bit more light on this?

Thanks in advance,

Sid

Also I have not checked the cam follower since owning the car (8K mile) currently at 76k. Probably a good idea I guess...

Bump anybody?

**GujuNilesh** · 03-25-2013 01:35 PM

p0089 usually means cam follower. Get it replaced by the dealer. Its under warranty. I'm getting mine done right now. But they are taking forever to get it replaced. It's a good thing they let me borrow a top of the line a6 2013 model. lol.

I am out of warranty. Is this something that can be replaced under an open campaign for free? If not I would rather get a high quality follower and give my money to HPFP then the stealership. Please let me know.

with a p0089 code the stealer should check it- however, you may have to pay for the labor if it is not the culprit. The dealer should cover the repair up to 120k i believe, but usually will not replace until it is destroyed. It is very easy to check yourself- I recommend a diy to be certain. my 0089 code was not the cam follower.

Talked to the dealer a bit ago... They want $120 for a diagnostic. If it is the cam follower they wave the fee, if not I pay the $120 and it goes towards the repair needed....

Just erased the code and threw it back into stock mode before I left on my way home from work. Gonna see if it comes back up. If so I'll check the cam follower condition, but what other causes should I take into account? Any inexpensive things that can be replaced that may remedy if it does come back?

**Jhad** · 03-25-2013 03:34 PM

The sensor on the pump can go bad- i forget the part number right now. I was getting p310b as well, so my hpfp and lpfp were bad.

**06AudiA42.0T** · 03-25-2013 06:18 PM

I have a 2006 Audi A4 2.0T fsi.
Im at 124k miles (no warranty).
I keep getting the P0089 and P2293 codes.
Where should I start? I read through the thread and see people have replaced the fuel filter, High/Low Fuel pressure regulator(s), High/Low pressure Sensors,CamShaft....
The engine light goes on and off every few days. It usually drives perfect but I notice at high speeds it cuts out. Would this be my High or Low? Sorry for all of my questions Im still trying to piece this all together and any help would be appreciated. I am trying to sell my Audi but it would be a whole lot easier with that light off. I want an honest deal.

**Toxygene** · 04-12-2013 09:13 AM

I got the same thing as the guy above me. I got the folowing codes after driving home after a meetup:

P0089 Fuel Pressure Regulator 1
P0089 Fuel Pressure Regulator 1
P2293 Fuel Pressure Regulator 2
P0087 Fuel Rail / System Pressure - Too Low

Conditions they occurred under:

Let the car warm up before I left a meet for about 20 minutes. Had some spirited driving while getting back on the freeway. While on the freeway, had to get off to make it to another freeway interchange. As I was getting back onto this other freeway I experienced some kind of fuel cut. Nothing happpened and I put the car in cruise for the next 20~30 min. Towards the end of the trip I took it out of cruise and had to maneuver around some moving obstacles and experienced the fuel cut even worse this time. Still no engine light. Gas tank light came on right as I was pulling into the station. Took it easy on the way home after filling up with gas but got the fuel cut so bad that the car lost speed while I was driving from about 75 down to 40. CEL came on. Limped home as the care seemed to loose a litte of it's punch. As soon as I got home I retrieved the codes and cleared them to see what the car would do. turned it on a few times and nothing seemed out of place. checked under the hood and everything looked fine.
This morning my wife take the car to work. No more than a block from our house the car dies on the street. She flags me down as I was leaving at the same time and I tell her about the fueling issues. She makes it to work but I can imagine the language in the car was not pretty.

As for what I have on the car

APR High Flow Pump
H2 Sport Cam Follower Fix

AEM Cold Air Intake
Black Forrest Industries Oil Catch Can
Brand New Spark Plugs
Coilpacks were supposedly replaced about 30k miles ago.

We are out of warranty but I'm wondering if the dealer would even fix it with the H2sport cam follower fix and the APR pump. I'm wondering if it's the thrust sensor or something bigger where I'd have to replace the whole pump. I only have the weekends to fix this, so if I could buy the part and replace it myself I'd do it. I've read through this thread but I don't see anything conclusive. Any ideas?

**80sGuy** · 04-12-2013 09:23 AM

^^There's a campaign for the Thrust Sensor (G410) and most likely that's what it is.

**Toxygene** · 04-12-2013 03:26 PM

Thank you. What kind of campaign are we talking about? Is this something I could simply take care of on my own? Seems simple enough to get to it. Is the part number listed in this thread. I'll do a search specifically for it.

**CleverA4Name** · 04-12-2013 03:59 PM

Yeah does anybody have a campaign or recall bulletin on the thrust sensor?

**80sGuy** · 04-12-2013 04:07 PM

It look something like this. Call your dealer.

**Toxygene** · 04-13-2013 08:15 PM

I bought the thrust sensor and had a shop throw it on. They then drove it around for a day without any issue. Audi in Riverside said I might be able to be reimbursed for the part as it's covered under a TSB.

So far no codes. I'm going to go ripping around tonight to make sure.

**80sGuy** · 04-13-2013 10:21 PM

I did the same on mine and got a reimbursement. Not easy though because AOA would need proof of the CEL on paper, and that the part was indeed installed for the reason.

**Unit1Evangelion** · 10-30-2013 10:46 AM

I know this is an old thread and I have read it all but I'm having the same problem yet I can't find a solution and Audi isn't really working with me.

I bought the car in Feb. drove it from Washington to SoCal. In that process the driving down the CEL came on and ran a check with my Vag Com and got this code. I took it in a couple of days after getting back after finding out about the recalls. They said they didn't see any problems with the fuel system, cleared the codes and made me pay.... 2 months later, my car starts hiccuping when pressing the throttle, rough idle and delayed starts. Broke down a month later. Had a buddy help me and he got me a LPFP because the old one wasn't priming.

A few weeks later, the CEL came back on. I replaced the fuel Filter and did a full tune up(sparks, coils, oil, filters, fuel system cleaners, MAF...etc) and cleared the CEL. 250 miles later, the damn thing came back on. Well fast forward til now. Car was acting up for 2 weeks with very bad throttle response and very rough idle just to break down last week. Towed the car to Commonwealth Audi again after talking to AoA about a letter I have saying that the HPFP, Cam Follower, Cam Intake are under warranty and that I had a receipt from the previous owner stating that the Fuel Sensor was replaced before from the same code and if it came back again the HPFP needs to be replaced. Now I took it there and they say the LPFP is bad yet everything else in the fuel system is good. Car was priming perfectly fine it just wasn't getting fuel pumped into the engine. I don't understand. Now I have to fork over more money to pay for them to tell me again that nothing is wrong and they won't replace it.

Question is, wtf is making this code pop and why are the so adamant on saying the HPFP isn't bad at all? Paid over $300 just for them to keep telling me nothing useful.
