<ul> <li><a href="/problems/vw-check-engine-light-is-on"><b>Engine Light ON</b></a>: The check engine light or service engine soon warning light is illuminated, indicating a problem with the ignition coil 7 secondary circuit.</li> <li><a href="/problems/vw-engine-runs-rough-shortly-after-start"><b>Engine Running Rough</b></a>: The engine may run rough, which can be linked to issues with the ignition coil 7 secondary circuit, affecting engine performance.</li> </ul>

<ul><li>The ignition coil 7 may be faulty, leading to improper spark generation and engine misfires.</li><li>An open or shorted harness in ignition coil 7 can disrupt the electrical flow, causing the circuit to malfunction.</li><li>Poor electrical connections in the ignition coil 7 circuit can result in intermittent or weak signals, affecting engine performance.</li></ul>

<ul> <li><b>Initial Inspection</b>: Check for any visible damage or corrosion on the ignition coil 7 and its connectors. Ensure all connections are secure and free from debris.</li> <li><b>Check Ignition Coil Resistance</b>: Using a multimeter, measure the resistance of ignition coil 7. Compare the readings with the manufacturer's specifications to ensure they are within the acceptable range.</li> <li><b>Inspect Wiring and Connectors</b>: Examine the wiring harness and connectors leading to ignition coil 7 for any signs of wear, damage, or disconnection. Repair or replace as necessary.</li> <li><b>Test Power Supply</b>: Verify that the ignition coil 7 is receiving the correct voltage. Use a voltmeter to check the power supply to the coil when the ignition is on.</li> <li><b>Check for ECU Faults</b>: Scan the vehicle's ECU for any additional fault codes that may indicate a broader issue affecting the ignition system.</li> <li><b>Replace Ignition Coil</b>: If all tests indicate a fault with ignition coil 7, replace the coil with a new one and clear the DTC code. Re-test to ensure the issue is resolved.</li></ul>
