buffalo Posted March 17, 2008 Posted March 17, 2008 Cars been driving like a bag of bolts recently. jus back from the garage after getting the plugs uprated as i thot this was the the problem. on the way there it felt like it was in limp mode and the turbo wouldnt kick in. on the way back it felt slightly more responsive but struggled to rise through the revs and dnt think it breached 60 mph???? Garage plugged it in and said the fault code was for EGT sensor, this his been coming on and off for a while now and jus thot it was due to the map. Now its obvious the turbo isnt working but i expected a big bang or horrible smoke or some outward sign to say it was knackered??? when i got home i lifted the bonnet and gave it a rev to see if i could hear or see anything. It revved quite freely but there was no induction noise or dump from the dump valve?? So anyone any ideas before i shell out for a new turbo?? the cars a newage WRX 03

So anyone any ideas before i shell out for a new turbo?? the cars a newage WRX 03 what fuel do you run it on? this happened to me when I got the car and ran it on 95 for a while, after a few fast runs the car went into safe mode. after a few tanks of vpower and a remap it was fine. or just reset the ecu.
frank c Posted March 17, 2008 Posted March 17, 2008 (edited) Might be worth checking to see if the circlip on the actuator arm on the side of the turbo is missing or popped off..This happened to mine and sounds like the same results.. Worth a look......... Edited March 17, 2008 by Frank C
buffalo Posted March 17, 2008 Author Posted March 17, 2008 cars mapped to run vpower, and its run on just that. carry NF in the boot incase i ever need to put 95 in it

buffalo Posted March 17, 2008 Author Posted March 17, 2008 kinda annoyed at the garage thot a wee bit more investigation couldve been done. they noted a rattle from the turbo area though. what would cause a rattle?
buffalo Posted March 17, 2008 Author Posted March 17, 2008 this any easy fix? easy to find? i am pretty ignorant when it comes to things of this nature
thewelsho Posted March 17, 2008 Posted March 17, 2008 this any easy fix? easy to find? i am pretty ignorant when it comes to things of this nature If your turbo is goosed mate, I know a man who has a replacement TD04 from a WRX06 with 20K on, he'll do you a good deal! Also has an intercooler to go with it if you needed that too!
buffalo Posted March 17, 2008 Author Posted March 17, 2008 cheers i'll have a look, think there is some sort of heat shield cover thingy that covers the top of the turbo where that goes. will i be doing any further damage if i continue to driive it? ^^^^ hopefully wont need it Welsho, but keep an eye on your pm's lol

buffalo Posted March 17, 2008 Author Posted March 17, 2008 the garage turned the light out, but it came on a couple of miles down the road. the fault code has always been for the EGT and the car drove fine with this on previously, hence the reason i dont think its an issue though may be wrong
turbo2000wagon Posted March 17, 2008 Posted March 17, 2008 I wouldn't point the finger at the turbo just yet. Do you have a boost gauge on it so you can see if it's running any boost at all? Mine wouldn't boost above 7psi and it was the boost solenoid stuck closed.
buffalo Posted March 17, 2008 Author Posted March 17, 2008 nope, no boost gauge. how would you check that? take it its a garage job
turbo2000wagon Posted March 17, 2008 Posted March 17, 2008 nope, no boost gauge. how would you check that? take it its a garage job I put a manual boost controller on (solenoid is then disconnected) and the boost came back. This was after taking the turbo off and looking at it, so I can recommend checking out a few other things first. What you can do is disconnect the solenoid and put 12 volts from the battery onto the terminals of the solenoid and if it's ok you will hear an audible click. When you're driving the car can you hear any turbo whistle at all, say in 4th gear at around 50mph when you put your foot down? If it's whistling it's spinning ok. Check the turbo hoses from the turbo to the intercooler and the intercooler to intake manifold, also check the hoses to/from the blow off valve. If you have a split in any of these this will also screw your boost.

Trackhound Tuning Posted March 18, 2008 Posted March 18, 2008 Definately worth checking the actuator arm as previously mentioned. Buffalo - not sure where you are based but if you're near edinburgh this weekend let me know if you are and I'll have a look at your car. It does sound like you are having actuator or boost control circuit problems. I also have diagnostics software called ECUexplorer that can read and reset the subaru diagnostic trouble codes on the new age wrx so we can see if there are any codes associated with your boost solenoid or any other issues with your motor for that matter. I have a spare WRX boost solenoid you can have if it's faulty as it's rattling around my garage at the moment. Cheers Alistair
buffalo Posted March 18, 2008 Author Posted March 18, 2008 seems to be a buzzing/whirring noise coming from this area this first pic in particular
buffalo Posted March 18, 2008 Author Posted March 18, 2008 had a wee pull at the acuator arm but its solid so i presume its in place. trackhound tuning, i'm from east kilbride, jus outside glasgow so not in the area, though thanks for your generous offer and would happliy nurse it out your way if you think you could help and the car wont break en route lol
simon_mcwilliam Posted March 20, 2008 Posted March 20, 2008 If the egt sensor is faulty, it seemingly puts the car into limp mode to protect it, so the sensor could be the problem after all.
