Saab - 9-3 :: 1999 - No Power Upon Acceleration After Installing New Turbo
Jun 28, 2011
1999 Saab 9-3 2.0/turbo, manual, 159K miles. Barely replaced turbo (with new turbo) at 154K miles. Had sluggish power after new turbo installment. I had informed saab mechanic that the car felt sluggish upon receipt, to which he replied I could pay extra for a "performance" tune up. But, now months later the loss of power problem has worsened. Since I paid dearly for a complete new turbo installation I'd expect the same level performance as prior to the old turbo going out.
To be clear: no turbo power upon acceleration, slight whirring noise heard when stepping on gas, turbo pressure gauge stays near end of white zone, barely top of white, but needle doesn't leave white into yellow zone as it's suppose to when full gas is given or when revving up rpms to 4800 while switching gears.... absolutely no power, nothing. I'm relying on down-gearing for some engine power when going uphill - tis' that bad. Also, no black smoke or indicator lights. In researching people mention both vacuum hoses or waste gate come up as possible culprits to turbo-related power loss.

I'm on the road and I pulled over for a pit stop so I don't have time for a search right now, but I noticed under heavy acceleration a turbo whine so high pitched it almost sounds like metal on metal. Is this normal and I just noticed it, a leak somewhere, or maybe indication of something worse? The truck seems to be running ok otherwise. It's an '02 w/7.3 and 220k miles.

2003 6.0 F350... Under full throttle from take off goes about 20 mph just revs at 2500 let off the throttle in feather it shifts and acts like it wants to go just not allot of power sometimes. In neutral won't rev past 2700 rpms I do hear a screech from the turbo on acceleration and declaration. Also if in tow haul the truck won't shift at all. I can get it up to speed but even the smallest incline drops to 50 mph then takes bout 2 miles to get it back up to 65 mph or if I go downhill.... turbo makes the noise the whole time sometimes goes into passing gear in have to let off in it kinda my the truck hop in this is at 60 +mph. Only thing I have really tired was fuel filters and checked at plugs and boots.

1995 Saab 900 Turbo. Bought new. Lifetime history of complete battery discharge if not driven at least every 2 weeks. New alternator, multiple batteries of no benefit. Have left on flowmeter for up to 1 week at dealer service center without unusual demand on battery.

My son has a Saab 9-3 that we have spent several thousand dollars on repairing since we bought it for $3200 less than a year ago.The car has a little less than 100,000 miles on it. Now have about $7300 in it. Had motor rebuilt, water pump replaced and several other more minor repairs. Was driving it this weekend when he heard a loud whining sound then a puff of black smoke boiled out of the exhaust. It still turns over and runs but we had it towed to a shop. My husband things the turbo is shot. Could it be something other than the whole turbo having to be replaced? If it does, is this going to cost a fortune? Should we even put any more into this car? We have so much in it now that we hate to throw it away, but afraid of other major repairs adding to what we have already put in it.

I am experiencing a power/boost pulse when under moderate to heavy acceleration. I'm wondering if this is a sign of my diverter valve failing or another issue withing the turbo system.
I don't have a boost gauge and the main pulsing seems to be between 2800 and 5k in the rpm band.

So I bought my first diesel last night and I'm in LOVE!!! It's an 06 F-250 with 6.0 (obviously). It's bulletproofed, rebuilt FICM, EGR deleted, and 4 inch exhaust IIRC. Previous owner had an issue with the turbo and replaced it. New turbo was DOA so he rebuilt it (sort of) and added a precision turbo (again IIRC) back housing (I think) to it. It has an SCT tuner as well and I have it set on the custom economy tune. Is this normal? Is there something I need to be doing about this?

I'm relatively new to the 6.7 engine , I have a 2014 F-350 SRW with aprox 51,000 miles on it. Normal driving I see about 8 to 10 psi of boost even under moderate acceleration although at times it will go to about 18 psi at WOT and it does this with heavy loads. At moderate acceleration the boost will jump to 10 psi quickly but immediately stop there and sometimes as the RPM"s increase boost pressure decreases. Only issues I have had with the truck was a clogged EGR cooler.

6.7 Boost ... Under full acceleration does the turbo go to 40 PSI or stay in the middle at 20?

So I recently got this GTi and I was wondering what steps I should take before putting a bigger turbo on this car and the steps I should take when putting a bigger turbo. What should I do first be for considering a new turbo?

For a month or two now my truck has been making a squeal and the turbo has been sticking after hard acceleration. The sticking was a woebegone unison ring and I was hoping the squeal would be resolved when I cleaned the turbo but it didn't, in fact, it got worse.
It used to be occasionally and go away after warming up, but now it's more constant than not. It goes away when the VGT does its idle cycle and once you get up to speed.
Here's the sound - YouTube.....

Well I am at a loss now. Rebuilt the turbo with a new wheel and kit from Riffraff. I still have no power, no boost and no codes. The new wheel whistles. I can hear it. It sounds way better than the old one. But still no power. I really don't know what to do now.

As I was getting ready to leave town with the tractor loaded up, I was accelerating with the turbo spooling up when I heard a bit of a pop and lost power (engine still running and all, just very low power like you get when the turbo fails). I wasn't far from the shop so I came back and started getting a lot of white smoke out of the exhaust, it doesn't smell like diesel, probably more like oil. Definitely smoke, not coolant. I pulled it around back and shut it down to go grab AE and scan it and it shows a P0475, starting it back up has light smoke at idle and it idles fine but as soon as you give it any throttle it starts smoking pretty badly.
Researching it looks like the most likely cause for this is the EBPV itself but before tearing it down that far. This is the only code it's showing.
Truck has 272k on it, turbo was rebuilt a couple of years ago but we didn't do anything with the pedestal at that time. I guess in retrospect, I probably should have done the EBPV delete and the resistor fix then but I didn't think about it at the time.
On another note, my AE is not showing any of the system test for some reason, the drop down is blank. I have version 7.0.1, so it's an old version but I'm working on an old truck, so... What that might be? I've got the truck pulled into the shop now to let it cool down. I'll probably let it sit overnight and take the turbo and EBPV out tomorrow unless someone has a better suggestion...

I have a 2004 VW jetta GLI 1.8 turbo and when i get it to about three and a half grand it feels like my turbo is giving out, all acceleration stops. But I doesn't do it all the time, meaning not every time i step on the gas, like I can step on it all through first and second, and it will do it in third or visa-versa. Which leads me to believe that it could be a fuel delivery problem but I don't know, im new to the VW game. The check engine light will come on while the car is bogging down but as soon as the rpms go down it will turn off.

So my understanding is that if your turbo is leaking oil, you either need to rebuild it or get a new turbo cause the one you have is shot.
I have some oil leaking, but it's not a ton. One one of my buddies was telling me that it's possible that the amount that is leaking is normal due to the PCV (Pressure Control Valve) system, or something like that. Here are a few shots of the turbo, as well as the boots that are leading up to the turbo.

While my turbo is out I decided to delete the EBPV. I removed the butterfly and rod, & pounded in some 3/4 inch freeze plugs. Are there any mods that need to be done to the pedestal, or can I just leave it the EBPV plunger unhooked? It's not leaking, but will it leak if left unhooked? Or do I have to gut it and tig weld the oil gallery's

Dumb question but how do I remove the air filter intake from the turbo Its a little oily there from a fuel or oil leak but I dont see a clamp holding it on the turbo?
Also what is the e clip? Is it the little thing holding the wastegate rod on the exhaust turbine? Can I just pull the rod up off the clip?

I've been mulling over the idea of doing a muffler job on my 2002 f350 7.3 cc short bed. I do tow on and off for work and dual material for work. I am thinking of upgrading the exhaust because I noticed a couple small leaks in the muffler and I'd like to lower the egt's for the truck so it breath a bit smoother. I'm not a fan of the really high pitched sounds I've heard on some I want it deep and heavy sounding. The turbo is fine for now but eventually I'll need to know what to upgrade to once it starts to wear out. I don't plan on doing dumb chips or tunes because it's not a toy truck but a work and daily driver.

I'm getting ready to change the glow plugs in my dad's e99, 196k on the clock. When I pulled the air intake tubes I found some oil in the turbo:
The inlet tube also had a bunch of gunk in it too:
Does this look like it is caused by the PCVor is it a bigger issue?

I have an 02 crew cab SB 7.3L. The best way to I know to describe it is a sorta like a metal ringing noise. It just started this afternoon while pulling a 9k camper. It only does it under load. Boost stays the same and it happens in all ranges from 5psi to 15psi. It is intermittent. It sounds like it it coming from the turbo. I pulled off the boot and could not feel any play on the intake wheel.
After unhooking trailer and taking for a test drive I can not get it to do it again? The turbo was rebuilt about 4 years ago with a wicked wheel but has only seen about 18k miles since the rebuild. A quick look at the boots appear good but didn't get to take them off before going to work. I will try to post video.
