I recently had my check engine light come on. I used my friends OBD connector and got a P0089 code which is a fuel pressure issue. I went to the dealer and they said it was my low pressure fuel pump. Parts and labor would cost me around $700.

When I got home I decided to look for the part, found it, I think, on ECS tuning.

This is the part: Audi B7 A4 Quattro 2.0T Engine Fuel Pump ES#440839 In-Tank Fuel Pump - 8E0919051CQ

I wasn't able to find anything that said "low pressure fuel pump". But after some Googling i found that the low pressure fuel pump is in the tank. And this is an in-tank fuel pump. So I'm assuming that this is it. If anyone can confirm or deny, I greatly appreciated.

Basically I'd much rather spend ~$250 for the part and do the maintenance myself. I'm trying to learn about cars in general so I don't get hustled out of potentially thousands of dollars.

My question, aside from whether or not that is the correct part (link above), is changing out this fuel pump a job I could do myself? The only maintenance I've done was change my oil, that took a while but like I said, I'm learning.

I'd possibly have some help from more experienced car owners, a friend who used to own a VW GTI, and another who's just a gear head in general.

I'll continue to look for a tutorial of some sort, but if anyone has one, or can link me to one, I'd be deeply grateful. Thanks

 

I'm curious to hear how this goes. I have a very intermittent P0089 (it throws the code maybe once a week and usually only in the morning with a cold start--then the code goes away on its own).

It was worse before I had them do the Fuel System customer service repair (they replaced my low pressure fuel sensor, intake manifold runner motor, and would have replaced the PCV if I hadn't had an aftermarket one--all for free). I suspect since I'm still seeing the problem, my LP fuel pump is on its way out, but I really don't feel like dropping the tank and trying to replace it myself, so I'll keep waiting until it dies or starts leaving me stranded.

I did a lot of searching on this code and it seemed like it could be a number of odd problems. The sensor was the most common cause, but since they already replaced mine (and you had the dealership diagnose it, so I would assume they checked to see if the "recall" had been done), I guess that's not it.

 

Just to follow up on this, the check engine light became much more than intermittent--it was on almost all the time. Same code--P0089. I took my car back and had them diagnose it (paid $150). I talked to the tech and he said my low pressure fuel pump is nearly gone. It typically cycles on and off and he said mine is running nearly constantly to push enough fuel to run the car. They also replaced my original PCV (since I put the stock one back on) under the customer service action which was nice.

I choked when they quoted me $1100 to replace the fuel pump and said I'd limp along for a while.

I've driven it about 50 miles and the CEL hasn't come back, but I figure it's only a matter of time until that trips and/or the pump fails. I might order that part and see if my mechanic will tackle it--he's good, he's just not a german specialist and his parts suppliers suck when it comes to getting parts for my car.

Did you ever try this?

 

I know I'm talking to myself here, but maybe someone will find it useful in the future.

After about 100-120 miles, my CEL came back on with the same code (P0089). I called my local German specialist shop (they've done some work for me including my t-stat, in the past). He quoted me about $420 over the phone and I about fell out of my chair. I asked him if that was just the part or the full charge and told him what the dealership quoted me. Needless to say, I'm taking it in next week to have the fuel pump replaced--it's not even worth me shopping around or trying to do it myself considering my price for the pump alone is around $250. Hopefully, that will finally lay this problem to rest!
