Symptoms. I removed the turbo charger and put in on the bench (just like Chris said). While two competitors at Diesel Power Challenge 2015 proved it can be turned into a true A friend's 1G FWD turbo whined loud like a supercharger at anything 0psi or more, and the j-pipe was leaking at the turbo. Signs & Symptoms of a Faulty Wastegate Sameca Pandova Updated April 01, 2017 A wastegate is a device mounted internally or external to a vehicle's turbocharger that ensures the turbocharger does not produce more boost than desired. throw some soapy water on actuator with engine running at high idle (1000 RPM or better). Vacuum is supplied from the vacuum chamber, this chamber is supplied with a vacuum from the intake manifold via a one-way valve. I don’t know anything about diesels or turbo chargers but I did have a service manual with instructions on the test and adjustment procedure for the turbo waste gate actuator. 7? two that i know of went out in the last month or so. In most cases, a wastegate is a relatively simple valve, controlled by a pressure actuator linked to the boost pressure of the turbo. I think the turbo actuator is faulty or It does have a new turbo, Back pressure sensor, MAP sensor, EGR valve. There are a number of operating symptoms depending on the source of the problem. Now when you say farting, do you mean the truck will be pulling, then make a noise like someone is coughing, and at the same time will surge from loosing power at that moment and do that over and over? Thank you for the info, I did find and buy a turbo actuator that is used but works well and am a little skeptical about it having to be calibrated to a particular turbo, we all know that the dealers want to sell you parts and get their huge mark-up on them too. A friend's 1G FWD turbo whined loud like a supercharger at anything 0psi or more, and the j-pipe was leaking at the turbo. 2D Electronic Turbo Actuator Repair Service Affected Part No : G149 G202 G208 G-221 712120 728680 758226 6nw008412 For part numbers not listed here, yes, it regulates the manifold pressure and the fuel to the engine, so when the turbo kick in it as the right amount air and fuel for the turbo boost. For someone who doesn't want to spend big on a new turbo or modifying their up pipe to suit an external gate the actuator is a pretty good option. Not sure if this is the case with Diesels. sounds like actuator is leakingalso check wires at plug to VPOD that controls turbo. This is apparently relating to the actuator which controls the position of the vanes in the turbo. It sounds to me more likely the turbo actuator has failed or it may just have a vacuum leak on the rubber pipe to the actuator, if you need a turbo cheap call my Wastegate actuator - this is the small gold canister on the side of your turbo that pulls the rod to the wastegate. The turbo control valve controls the air to operate the actuator. When this happens the actuator struggles to move the vanes in response to command; this normally causes temporary increases in turbo boost pressure. 2. Designed as a direct bolt-on replacement for the factory part, the Porsche IWG is easy to install and requires no special tools or fabrication. I had cut out the cat, when we got the vehicle last year, but the damage was already done. It doesn’t make sense to pay for an entirely new turbocharger if just the electronic stepper needs replacing. Volkswagen Golf V (2004 - 2008) - 2. how can i tell if my turbo or waste gate or my wastegate actuator is bad. I dont have a boost leak anywhere and it is an intermittent problem. If the codes are P132B, P2262 or P2263, or there is evidence oil oil leaks or the oil level is low, turbo actuator operation and turbo bearings should be checked. I've had similar symptoms, although my turbo actuator rod only moved a few mm off the bottom and had most of the travel left unused at idle. If there seems to be just a bit of a delay between the time you push on the gas pedal and the time it takes for The observation that it revs quicker when you play with the actuator makes me think it's still turbo-related, and since you've changed the turbo, it's not directly the turbo but something in its path or controlling it. most compressors will do that. If you remove the pressure feedback to the actuator, there is a chance of boost pressure increasing beyond the capabilities of the turbo (under the right circumstances), which can cause damage to the components, as you have mentioned. I have run VCDS and it shows an electronic fault with the actuator. 2 diesel auto X-Type. The wastegate is like a little door on the turbo. When boost pressure gets to a pre-determined level (by the wastegate actuator) the wastegate opens to let excess pressure out the door. The air pressure is sensed typically from either the inlet manifold or the compressor housing of the turbocharger. The variable geometry turbo (VGT) actuator should be checked for operation: The engine should be at operating temperature. Could be the turbo actuator valve not moving the variable turbo correctly, but just enough to not throw a code. It is loud and nasty, and usually goes hand-in-hand with poor fuel economy and sometimes a rough idle. TurbochagTues Turb ochhr Turbochargers are very reliable: less than 1% of turbos fail due to a manufacturing fault with the turbo itself. I have performed an output test with VCDS on the actuator and there is no movement of the actuator during the test. If you unplugged the electircal plug at the vpod this would do the same thing as plugging the line off. 6L GM Duramax. On the actuator pin 1 is vnt+ and pin 2 is vnt Nearly all turbocharger-related problems are thexesult of a handful of causes. . In most cases where a P0299 DTC has set as a result of excessive clearance, it was generally around . The pressure actuator is fuly extended and Actually there are two kinds of bad EGR valves, with different symptoms. Using a small strip of rigid steel attached onto the end of the rod can make measurements easier. Failed or sticking vanes inside the turbo or the vane control ring inside the turbo can cause the same symptoms. This feature is not available right now. Please try again later. The wastegate actuator on the 94-2000 turbo does not have a spring, when no vacuum is applied the wastegate will “flop” back and forth. The Turbo Actuator looks simple to remove (& hence replace), but I think I've heard/read somewhere that its re-alignment is critical, but I find that hard to believe since it appears to be a simple bolt-off, bolt-on exercise. I'm a tech at a chrysler dealer, and we've been getting TONS of the 6. Next, time to test the turbo. turbo actuator symptoms
