Tiguan :: Turbo System - Power / Boost Pulse When Under Moderate To Heavy Acceleration
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.
Ford 6.0L Power Stroke Diesel :: 2004 - Turbo Won't Have Boost?
I have a 2004 Excursion with the 6.0. Lately it seems like the motor just doesn't have the boost it should. Funny thing is that the boost reading through the edge cts seems to be right. Under full acceleration it will pull 27 psi boost and 3900+ ICP pressure. No codes are being thrown. It just doesn't "feel" right (seat of the pants) and it also sounds louder but I don't known this for sure.
Where does the CTS get its boost reading from? The truck has new boots on the hot side from riffraff. Anything I can check?

Having this problem, what to do to correct it? There is no hole in the boot and this just started about a year ago. Does not do it all the time.

Just wondering, what the max boost rating on a stock turbo, stock engine in a 2011 is. I know the gauge goes up to 40 PSI, but I don't think I've ever seen my go past 20.

Check engine light is on says low turbo boost but gauge says it has a lot of boost. Only happened after I put catalytic back on for smog test. Before that no problem.

I have a 2013 F350. Since it was new in August the turbo has made a chattering sound that sounds to me like the waste gate (if it had one) is opening and closing rapidly. Almost like its building boost and dumping it over and over again. Usually happens when it is in 6th gear around 1700 rpm under light load. It also does it from time to time while plowing snow. You can power through it or let off and it will go away. My local dealer where it was bought new put a new turbo on it and the problem still persists. The truck just turned over 8k miles and has been in several times in attempt to resolve the issue. They say that there are no codes on the truck nor does Ford have anything on their service web. My dealer claims that no one has ever had the issue.

I've been having issue with my truck lacking boost over the past month or so. The psi levels are normal in the morning when I start it up cold, the problem almost always occurs at start-up when the truck is somewhat warm and has been sitting for an hour or more after use. I've had boost levels at idle from -0.14psi to -0.56psi and as low as -1.2psi when driving as the problem is occurring, but it eventually kicks on and goes to normal levels after several minutes of driving. After originally taking the truck to a local diesel mechanic I was told it had EGR codes and they recommended installing an SCT tuner and cleaning the EGR valve to solve the problem. I had them install an SCT 5015 tuner and clean the valve but I've still been having the problems with boost.
View 2 RepliesFord 6.0L Power Stroke Diesel :: 2003 - No Boost - Oil Collecting At Tip - Turbo Seal?
I have an '03 powerstroke 6.0, 4 inch turbo back exhaust. truck had lost boost and would cut in and out if i got on pedal and now a little bit of oil is collecting at tip, could this be because of bad turbo seals? And could the turbo still be alright? Another thing, I'm losing coolant, and I have noticed when I took the EGR out and cleaned it, the valve itself was the powdery black carbon, the cooler was wet, and I know it's not supposed to be like that. I am not thinking head gaskets yet, cause if it had a blown head gasket, I wouldn't be able to drive it. It is currently sitting, and I'm just trying to fix it. Would I be able to fix the turbo seals myself?

This is a common problem. Mine goes to dealer in the morning for it. I haven't seen any recent posts within the last year on this. Did ford ever find a fix for my problem? When going up hill at low rpms I lose boost and hear the stutter out the intake..

The ford dealer in Las Vegas replaced my turbo with a remanufactured one. Coming off the line (like quickly pulling into traffic) it goes flat on power until I get a few RPM's. Even with the old turbo it never did that and I drove it for the last 30k miles with it throwing the low turbo boost code. They put a little over 100 miles on it for road testing (I did have other things that they worked on. {4x4 2006 F250, 6.0 engine, 110k miles and I bought it new}....
View 4 RepliesFord 6.0L Power Stroke Diesel :: Low Boost / Low Power And Horrible Acceleration
I have an issue with my 6.0. I was running the extreme street tune from IDP for the past 2 years now and recently purchased the xtreme X tune from IDP. I loaded in the tune and had low boost, low power and horrible acceleration. Max boost i would see is about 10psi and it would take about a solid minute to reach highway speed when merging on the highway. I went back to the stock factory tune and have the same issue. No boost leaks from the boots or pipes and no check engine light. What is going on?
View 2 RepliesFord 6.0L Power Stroke Diesel :: 2003 - Loss Of Power - No Boost On Acceleration - Vibrates?
I have an 03 6.0 Power stroke. My problem all started the other day when I started to occasionally not get any boost on acceleration and lose of power and a lot of vibration like it's about to cut out but it got worse now today I drove it about 5 miles into town when I got to town I noticed a rough idle I got gas in a gas can not in the truck. I got back in to leave and I had absolutely no power at all the truck stalled out and it was very hard to start finally got it started and it runs really rough almost like it's going to shut off.
So when I started driving I would only make it about a mile or so with out it chocking out and having to let it site for a minute or two and start it back up and go another mile or 2 and have it do the same thing all the way home all the time I have vary little boost if any at all except for when I first pull out now oil pressure is good and engine never over heated some of the codes I have is an EGR code and a contribution balance code for several cylinders I was thinking possibly a maf sensor or a clogged egr not working right.
Ford 6.0L Power Stroke Diesel :: 2006 F250 - Turbo Flutter After 50% Or More Acceleration
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?

Experiencing a squeal under hard acceleration at 3000 rpm with roughly 20lbs of boost, not present before and not present after 3000 rpm. light acceleration to 3000 rpm does not create sound, as well as turning 20lbs at a lower rpm (higher gear with throttle input). Truck has an EGR delete, EGR delete up pipe. EGR valve is still in place and plugged in. Truck did come with a banks six gun, so does not have EGR delete tune, however no trouble codes are present. What to check?

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.

Passat (B5) :: Turbo Surging - Boost Gauge Will Jump From 12 - 17 Just Back And Forth
I just bought a 98 passat 1.8t manual trans, its has 105k on it now, I am having a problem with the turbo surging. I am running about 17 psi however every now and then i can put it to the floor and my boost gauge will jump from 12-17 just back and forth, I also have a prob every now and then where it will only build 4 psi and stay there i can down shift take my foot on and off the gas and still no change then just all of a sudden 17 again both these probs are intermittent looked briefly at vacuum lines.

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.
View 14 RepliesFord 7.3L Power Stroke (1999-2003) :: Turbo Chatter Under Load - Boost Was Around 17 - 18 Psi
I have done some searching on this, seen a video on YouTube but haven't read anything that is firm on what it is. We pulled our 5er for the first time last weekend and the chatter was pretty pronounced in the Arbuckles here in OK. I was running around 65 mph when I hit the largest hill and as I was climbing my speed naturally dropped, boost was around 17 - 18 psi when the chatter started.
Is it something to be really concerned about? Is there anything to be done to prevent it? I'm pretty much still stock, only deletes have been airbox to 6637, and I deleted the heater by turbo for the boost gauge. Other than that everything on truck is still stock.
Ford 7.3L Power Stroke (1999-2003) :: Turbo Boost Loss And Engine Starting After 2 Attempts
I've got a 2002 Excursion which has been giving me a little trouble lately. I've got a DP tuner, 4" exhaust, afe stage 2, and gauges (boost, trans temp, EGT). I've been running these for about a year now without any truck problems until recently
So I noticed over the past couple weeks it has gradually been taking longer for the engine to start. Started off by just having to turn the engine over a few more times. Now it has turned into having to turning over the engine for a few seconds, then turning it to off, then trying again. It always starts on the second attempt to start my truck and sometimes really hard where it blows out a little black smoke.
Not sure if this is a correlation to the problem above or not, but I've also been losing boost pressure, and I'm not sure when this started since I haven't been on the highway for a while. I noticed this because this weekend I drove on the highway and saw that I was blowing some black smoke every time I accelerated which has never been the case.
So I check my boost gauge and see that I'm sitting at like 3-5psi when I used to be at around 10psi+. I also noticed when I accelerated the boost pressure would increase like normal but then quickly drop once I stopped accelerating which is unlike anything I've seen before in my truck. I don't seem to notice a huge difference power or throttle response, but then again 95% of the time I'm driving under 40 mph to get to work. So this problem could have started the same time as the starting problem, but I can't say definitively.
What this problem could be, what to check or test?
