jaylew Posted December 1, 2015 Share Posted December 1, 2015 Hey guys, I'm new here but not to the subie game. Still own my first subie, '96 Legacy OBW 5MT, but recently got an '05 wagon GT limited 5MT. I know pretty much all of what needs to be done to it and how to do it but there is one thing that has me slightly worried. After buying it, when I was driving it home, everything seemed fine as long as I kept the rpm's under 3k-3.5k. But anytime I tried to push the car (test the power), it seemed to hit a wall around 3000 rpm. If it wasn't for the fact that I could hear the engine and see the tac, I would say it felt like the clutch was slipping, but I know that is not the case since the rpm's did not spike what so ever. Besides that everything seems fine with the drive train. Since this is my first turbo'd car, not sure if that is the problem (I doubt it but then again I've never worked with them before). Also I wonder if it could be fuel pump / pressure or a leaking vacuum line or something. There are no check engine lights or warning indicators that come on when this happens and it happens in every gear. I wish I found this problem before handing over the money but my test driving was limited to a small parking lot since the car is not currently inspected. Anyway, any help or suggestions would be greatly appreciated! Thanks!

adb140275 Posted December 1, 2015 Share Posted December 1, 2015 sounds like a boost leak or exhaust restriction... Link to comment Share on other sites More sharing options...

jaylew Posted December 1, 2015 Author Share Posted December 1, 2015 ok thank you. The boost leak is my first thought but just wanted to get some other opinions. I am only seeing the VAG cable on ebay for VW's, is this the same cable you are talking about or is there another one that I am not seeing?

Moderators BarManBean Posted December 1, 2015 Moderators Share Posted December 1, 2015 Are you saying the car is just not accelerating past that point? Or are you literally feeling like you are hitting a wall (violent event, can be caused by fuel cut / overboost). Are you able to monitor boost? If the car is just not accelerating it could be a bad wastegate that's not closing / creating boost properly.

jaylew Posted December 1, 2015 Author Share Posted December 1, 2015 My time behind the wheel experiencing this was for only the drive home. There is some other work that needs to be done to the car before I can take it to get it inspected and drive on the road more. The car wouldn't really accelerate in the same linear fashion as it did up until the 3000 rpm mark so my initial thought was the fuel cutting out. I did here some kind of noise but nothing super catastrophic sounding. If the wastegate were not closing properly, how would that be fixed?
