  • Allroad Accleration Issues

    I posted this over at audizine, but local Canadians are usually far more helpful than international audi owners.

    I have an 03 Allroad 2.7T TIP and I recently put the 91 octane APR chip in it.

    Anyways,

    The car doesn't drive that well. In fact it's performance has pretty much dropped.

    I get serious lag when normally accelerating. the RPM's will spin up to 3000 ish and then jump up and down (+- 300 rpm's) until finally deciding that it will accelerate and then it really has power (like you'd expect) after that. But it's sometimes as much as 4 seconds before any power is applied.

    Also now when in fifth gear and accelerating, I basically can't go over 3000 RPM's without this just happening consistantly. Except I don't get power after a few seconds. I just get a wider throttle with no response. (Now that I've posted this at AZ it's happened in 4th gear as well. still more common in 5th gear.)

    I'm thinking to return the APR software and get my money back, and get a TIP chip and ECU chip from VAST. That might have to be a spring project.

    Anyone have any thoughts on this?

    An AZer mentioned I should check for any vacuum leaks, and DV leaks, and maybe just.. leaks in general. Could be some of the lines. My dials all show the right pressure, excepting in that I don't have a boost gauge, so I can't tell off hand.



    On a side note, I'll be doing the timing belt this weekend with Graeme, and I'm hoping that will clear up a weird RPM jumpiness on idle. We'll see. After watching graeme take apart his AR to replace the turbos, this should be a piece of cake. Buying him a lap-dance should end up in some interesting stories as well - mostly called "Lets play a game called 'Who gets a boner first!'" Strippers aside, while we're in there I'll check for any or all of this that I can visibly see. Probably post some photos as well.

    Advice or thoughts are definitely required and welcome.

    First of all, unless your timing is off, a new TB won't change any jumpiness at idle.

    Sounds like you may have a boost leak or else a bad EGT sensor or something. I would VAG the car to see if any sensors have crapped the bed, and then do a boost leak test on the car. Fixing these issues will definitely help smooth out your idle.

    For the TB install make sure you have the cam lock bar for the 2.7T and follow the Bentley manual to the "T" if neither of you have done a TB on this motor before.

    I would take the car to the APR dealer and tell them to find out why their chip made your car drive like crap. If they can't find the problem, return the APR chip, VAG and boost leak test the car, fix whatever problem you find (and you'll most likely find something between those 2 things), and let me set you up with VAST stuff (always a good idea ).

      Haha, shameless plug in there at the end?

      I'm off to london next week.. so.. I need to uninstall the chip right away, I don't have time to test it until September when I get back.

      :(

        x2 on the boost and vac leak check, make G do it while he is there
        I may appear to be nice, but don't be fooled, I probably don't like you

          'Generally' your problems aren't caused by the programming of the chip...
          What does happen is that the increased HP and TQ that your car now puts out makes previous minor problems more noticeable. Switching from one software vendor to another wont fix anything... its a matter of fixing whatever is wrong in the first place.

            im guessing your dv is leaking since you upped the boost, sounds like a leak somewhere.

              yea or bad EGT..

              when i first chipped my S4 it drove like how you mentioned.. basically bucked while accelerating.. was a bad EGT sensor.. only came apparant once chipped.. audi fixed it for me for free tho.. those stupid things are costly

                Like everyone else here is saying you probably have a big leak somewhere in your system. Scan and pressure test right away and you will find your problem I'm sure, I can pretty much guarantee it is not your chip at fault here. Oh and get a boost guage already especially with your car chipped running twice the normal boost pressure.

                  Like I said before, it's most likely a boost leak or bad sensor, but it's not unheard of for a chip to have faulty programming or be incompatible with a car's ECU. It does happen, you guys. I've seen it a few times before.

                    Okay, enough with the "it's not the chip". You drilled it home.

                    I'm returning the APR chip for other reasons. Once it's back to stock I'd like to delve into what exactly the problem is, and go from there. Plus if it's gonna cost large sums of cash to fix, having the cash back from APR will fund it. Plus I need winter tires.

                    I'll be checking for leaks this weekend. I'm hoping it's not the EGT, something like 500 just for the sensor.

                    I'll be getting a boost gauge soon enough, assuming I re-chip the car.

                    Ironically, I took the longest route I could possibly bear this morning to work, including a highway, drove the car hard, and had ZERO problems what so ever. Like it knew I was out for blood or something. Strange.

                    SCAN automotive recommend new DV's once I got the chip, but I wanted to let these current DV's burn out a bit. So that could also be an underlying problem.

                      why remove APR? i love mine.. anyways

                      if it is your EGTs a vagcom will tell you

                      and you can ask parts erik on here who works at royal oak audi in town and i'm sure he can ship stuff to you or get graeme to pick them up and drop them off when hes out west

                        What are the reasons for returning the APR chip? If the local dealer is good.. I would stick with whats local to you. You will notice very minimal gains by going with someone else... although a tip chip would be beneficial.

                        I ran APR products for many years and didnt have any problems.

                          We'll see. When graeme is out we'll take a look. Depending on what the car spits out, we'll see.

                          Problem is I'm off to London England next Thursday, and my moneyback from APR ends on Wednesday. If it is the chip or the chip is making the problems worse, I'd rather take it out. Won't cost me anything outside of 15 minutes of labour.

                          I just wish it drove like it did this morning all of the time. It positively sang. The APR performance when it IS working, is totally fine. I imagine VAST is not much different.

                              For the recond, local Canadian's proved to be INSANELY helpful. Congrats guys.



                              And thanks! Definitely helps since I know near to dick all about most of this stuff.
