fuel pressure
 

am having the fuel pressure code come up....... is there an actual fix for this... had the dealership change the sensor 3 times after that i figured it might not be the sensor.........they wanted to replace the pump.. but had another audi dealer look at it and they said the pump was fine.....came up off and on like a year ago and never came back now its back .. looking for info...

What codes are popping up? is the car seeming to run just fine?

im pretty sure its p0089 fuel pressure .......or whatver......ummm i know the cars have issues... it came on for a while...... then after i started putting.....top tier gas.......in it went away for like a year now its back...... i guess the fix would be to replace the pump...... im just looking for info on it . (hate having the check light on)... but i know ppl say bout the folower...... if u buy a new pump do they replace the follwer... along with the pump or not........just tryin to figure this out...... but car runs great. no change in anything.....info....................?

If the problem is at the point where the pump and follower need replacing, then the intake cam will probably need repacing too. Very expensive.

You can buy the cam follower from ECSTuning for $50 and do it yourself, it's a pretty simple job. They also have fuel pumps, check out this page:

However, if you have the dealer do all this it will be expensive like B7Night said.

Have you tried the fuel filter?

just sayin'

well. last time it stated comming up (bout a year ago). i changed the fuel filter... didnt really help...... i dono here this is a problem with the b7s..... but i have had the car to 2 dealers and i guy i go to who specailizes in audis.. and they all said nothing was wrong with the car..... indy guy actualy tested my pump (which was the dealers next step.... bout 500.......)... he said he ran it through all the specks. and pump. in his opinion isnt whats cuzing it. so i dono.. i was gonna change the follower. since its the orignal one and see if that helps... i just remember indy guy sayin it could have sumthing to do with the intake something.... but he made it like it wasnt major. work idk.. just tryin to gather ideas here
