SOURCE: How to clean EGR valve passages in 1993 Isuzu Trooper DOHC V6

You have to the EGR valve (sometimes the Intake manifold to EGR Vlalve line also). After you remove it take a drill bit the about 20 % smaller than the actual hole of the outlet side and rotate the drill bit with your hand to dig out the carbon. Aditionally the line coming from the intake manifold to the EGR valve will clog near the connection to the EGR valve. I use either a single piece of copper wire or the wire that you would use to tie ribar together to clean the line. When your done cleaning take a piece of vacuum line and connect it to the diaphram side and **** on it... then plug the line well with your thumb. Grasp the valve and blow thru it... Air should blow thru it freely. Remove your thumb from the vacuum line and try blowing again.. No air should pass thru the valve.
Then reinstall the valve and start the vehicle with the vacuum line disconnected (but blocked off) Use another piece of vacuum line connected to the diaphram again and **** on the line.. The vehicle should die or run really bad. If it does this then you cleaned it correctly.

Audi A3 TDI glow plug light flashing. Turbo doesn't kick in. Persistent problem now. Previously, it came and went.


hi
possibly the EGR valve is blocked.
one way to clear it. by taking it to a high way. drive in lower gear and more speed to clear EGR.
otherwise remove the egr valve and connecting pipe and clean the build up carbon.

1995 sl saturn cuts out and stalls after flooring gas pedal and after restarting if I do not touch gas pedal it will limp home but if I try to accelerate it will again die


it can be a number of problems would need more info but well go with the most common need to check fuel pressure if low poss cause fuel filter clogging or fuel pump inline clogging the fuel filter is usually the problem with most stall loss of power ---if good while running check the exhaust if it feels like is choking out or low than possible cat converter clogging ---if good than check throttle body my be clogging ir need repair ---if good check egr valve my need cleaning or replacement the egr valve gets clogged with carbon also check or replace air filter these are the few most common problems that can cause a performance problem

TRY THIS. REMOVE THE INTAKE ON THE RIGHT SIDE OF THE CAR .THE EGR VALVE CLOGS UP WITH CARBON SOMETIMES CHOKING IT OFF COMPLETELY. IT WILL BE HARD TO START WHEN THIS IS CLOGGED. CHUNK OUT THE CARBON WHERE THE BUILD UP IS. REPLACE WITH A NEW EGR.

Celebrity cutting out when accelerating


EGR is typically not employed at high loads because it would reduce peak power output. This is because it reduces the intake charge density. EGR is also omitted at idle (low-speed, zero load) because it would cause unstable combustion, resulting in rough idle. The EGR valve also cools the exhaust valves and makes them last far longer (a very important benefit under light cruise conditions).
Since the EGR system recirculates a portion of exhaust gases, over time the valve can become clogged with carbon deposits that prevent it from operating properly. Clogged EGR valves can sometimes be cleaned, but replacement is necessary if the valve is faulty.

I have just been told that my VW Golf GT TDi 140 Reg55 needs a new EGR Valve motor. Is this common for this Reg or Golf?


Since exhaust gas (therefore lots of carbon) runs through the EGR it isn't uncommon for them to fail. Sometime a simple cleaning can put them back in service. You'll have to remove the vavle and use a strong cleaner (like carb or brake parts cleaner) to remove the carbon. Clean the valve and the area where the valve bolts to the engine. I've known this to save many people hundreds of dollars in a wasted repair. Good luck.

I replaced the egr valve and the check engine light is still on so what do I do the code still says p0401


When you replaced the EGR valve did you check the EGR passage to make sure it wasn't clogged. Since exhaust gasses flow through the EGR passage carbon builds up on the walls restricting flow which can eventually lead to the code p0401 Insufficient EGR flow.
