    Hey
    The Check light came on, I immediately checked the hoses under the hood. And the EGR hose is hanging around, I can't get to where it should be connected?

    Look for a small inlet port. It can be so hidden that you can't see it from above

    Since when is the EGR valve controlled directly by negative pressure from the intake manifold?
    Look for a solenoid valve with a plug with wires (usually two wires) and at least one hose with a vacuum on the running engine.
    The task is a bit easier because this element should only be within the reach of the hose that is connected to the EGR.

    Check definitely not from EGR. Rather than lpg.

    Yesterday I searched the intake and I did not find any knot anywhere, anyway, it's hard to put your hand in, let alone the intake manifold. I'll try to look for a little webcam today.

    The valve is controlled directly by the hole at the throttle butterfly. Like in the old Opel

    The valve is from the collector flap

    The V-GIS is to be on the bulkhead, under the fuel filter.

    If you need photos, I can take them, but I will write right away that I removed the bracket a long time ago ...

    Good, now look where I wrote. The tube to the valve enters the upper port.
    Did you pull that tube out, was it already lying? Half of the Daewoo drives with the EGR valve disconnected, and the only error that can show up from the EGR is when the egieerem control solenoid is disconnected. Self-disconnection of the plug seems doubtful to me.

    Check lit up and what next? Increased, decreased engine speed? Removed tube means left air with open solenoid valve and different engine speed.
    Any other symptoms?
    So did you even read the error that shone?
    What you found and showed did not have to generate an error that you can read yourself.

    I found the cube (felt it) but I will have to unscrew the wheel and the hole next to the alternator will be easier for me to get to and install the hose. In general, the check turns on after some time with higher revolutions.

    By the way, the gas controller fell, when I replace it, I will see if the check lights up. The car runs ok, it is no longer muddy, now Brc Storm driver.

    In the end, I dealt with Check, the egr tube also helped in the proper operation of the engine, it does not go out, the revs are sticking. Check lighted up sporadically and went out for good after replacing the gas controller. Everything is back to normal.

Topic summary

✨ The discussion revolves around a user experiencing a "Check" light activation in their Lanos 1.6 16V due to a disconnected EGR hose. Various responses suggest checking for a small inlet port for reconnection, identifying solenoid valves under the intake manifold, and ensuring proper connections to avoid air leaks. The user reports difficulty accessing the connection point but eventually locates the necessary components. After replacing a faulty gas controller, the user confirms that the EGR tube's reconnection resolved the issue, leading to normal engine operation and the "Check" light turning off.

FAQ

TL;DR: About 50% of Daewoo Lanos drive with EGR disconnected; "The tube to the valve enters the upper port." Reconnect the EGR vacuum hose to the solenoid under the intake bracket to stop sporadic Check lights, especially on LPG setups. [Elektroda, g107r, post #17355907]

Why it matters: It helps Lanos 1.6 16V owners fix a dangling EGR hose and resolve Check Engine causes fast.

Quick Facts

Where does the EGR vacuum hose connect on a Lanos 1.6 16V?

Under the intake manifold, to a vacuum solenoid mounted on a triangular bracket. The tube goes to the solenoid’s upper port. You can feel it near the two solenoids grouped together. Reconnecting here restores proper vacuum control of the EGR. [Elektroda, g107r, post #17355907]

Is the Lanos EGR controlled directly by manifold vacuum?

No. The EGR valve is vacuum-modulated via a control solenoid. Locate a small solenoid with a two-wire plug. Start the engine and feel for vacuum at its hose. "Look for a solenoid valve with a plug with wires." [Elektroda, grala1, post #17355136]

How do I reach the hidden EGR solenoid port to reconnect the hose?

Access from the wheel well for more room. Remove the wheel and reach through the opening near the alternator. You can then guide the hose onto the fitting by feel. This route makes installation significantly easier on this engine. [Elektroda, memaka, post #17355925]

Will a disconnected EGR hose alone trigger a Check Engine light?

Often, no. About 50% of Daewoos run with EGR disconnected. The EGR code appears when the control solenoid’s plug is disconnected. If the tube is off during an open solenoid, unmetered air changes idle speed. Reconnect the hose and evaluate for other causes. [Elektroda, g107r, post #17355907]

My Check light comes on only at higher revswhat should I check?

Inspect the LPG controller if your car runs on gas. The thread author saw the Check after sustained higher RPM. They reported switching to a BRC Storm driver. Investigate LPG wiring and controller health before chasing EGR faults. [Elektroda, memaka, post #17355925]

Did replacing the LPG controller solve the Check Engine in this case?

Yes. After replacing the gas controller, the Check stopped appearing. Reconnecting the EGR tube also stabilized idle and prevented stalling. This resolved the reported drivability concerns. [Elektroda, memaka, post #17364654]

What drivability symptoms point to a loose or missing EGR hose?

Expect unstable idle and occasional stalling. After refitting the hose, idle held and the engine stopped cutting out. Monitor for further issues once vacuum integrity is restored. [Elektroda, memaka, post #17364654]

How can I identify the correct vacuum solenoid for the EGR?

Find a small solenoid within reach of the EGR hose. It has an electrical plug, typically two wires. With the engine running, check which one pulls vacuum. That is the EGR control solenoid. [Elektroda, grala1, post #17355136]

Where is the V-GIS or intake flap solenoid located on the Lanos?

It mounts on the firewall, under the fuel filter area. Inspect that spot when tracing vacuum lines to the intake. A removed bracket can change the exact mounting seen. [Elektroda, g107r, post #17355607]

What simple tool helps find the hidden inlet port?

Use a small webcam or inspection camera to see tight spaces. This helps when the port is obscured from above. It reduces guesswork while routing the hose by feel. [Elektroda, memaka, post #17355357]

Will unplugging the EGR control solenoid trigger an error code?

Yes. An EGR-related error appears when the control solenoid electrical plug is disconnected. Self-disconnection is unlikely on this setup. Secure the connector while you refit any hoses. Clear codes after repairs and recheck. [Elektroda, g107r, post #17355907]

How do I reconnect the EGR vacuum hose? (3 steps)

Use this three-step approach:
  1. Remove the wheel and work through the alternator-side opening.
  2. By feel, locate the solenoid “cube” and its vacuum nipple.
  3. Push the hose fully on and ensure a snug, leak-free fit. [Elektroda, memaka, post #17355925]

Are there two vacuum solenoids under the intake manifold?

Yes. Two solenoid valves mount under the intake on a triangular support. The pictured hose belongs to one of them. Track hose length to stay within reach. This detail helps avoid cross-connecting nearby vacuum circuits. [Elektroda, g107r, post #17355564]

Why can’t I see the EGR inlet port from above?

It sits tucked away and may be invisible from the top. "Look for a small inlet port." Approach from a lower angle or by feel. Patience helps when routing the hose in limited space. [Elektroda, NIXIE_123, post #17354884]

Could the EGR be driven from a throttle-body port on some variants?

Some setups route vacuum directly from a throttle-body port. "Like in the old Opel." Verify your routing before reconnecting hoses. Do not assume solenoid control without checking your car. [Elektroda, andrzej20001, post #17355555]

Should I read the stored error code before chasing hoses?

Yes. Scan the car and read the code instead of guessing. As one member asked, confirm what actually lit the Check. Then fix the root cause, not just symptoms. [Elektroda, g107r, post #17355907]
