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
- Two vacuum solenoids mount under the intake on a triangular bracket; the EGR hose connects to one of them. [Elektroda, g107r, post #17355564]
- EGR is solenoid-controlled, not direct manifold vacuum; find the unit with a two‑wire plug and vacuum on a running engine. [Elektroda, grala1, post #17355136]
- Easiest access: remove the wheel and reach through the alternator‑side opening to refit the hose. [Elektroda, memaka, post #17355925]
- Replacing the LPG controller cleared the Check Engine in this thread. [Elektroda, memaka, post #17364654]
- Refitting the EGR tube stabilized idle and prevented stalling here. [Elektroda, memaka, post #17364654]
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:
- Remove the wheel and work through the alternator-side opening.
- By feel, locate the solenoid “cube” and its vacuum nipple.
- 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]
