This guide covers the symptoms, location, and replacement procedure for the ECM. You&#8217;ll learn the book labor times, the importance of the shear bolts with locking compound, and how a pre-programmed replacement unit can save you time and money. Understanding these details helps you make an informed decision about repairing or replacing the module.<\/p>\n<\/div>\n<div class=\"info-section\">\n<h2>What the PCM Does in a 2014 Audi Q5<\/h2>\n<p>The Engine Control Module (ECM) in your 2014 Audi Q5 2.0L is a Bosch unit that acts as the brain of the engine management system. It processes data from sensors to control fuel delivery, ignition timing, turbocharger boost, and emissions components. The ECM also communicates with other modules over the CAN bus for features like transmission shift logic and stability control. When the ECM fails internally, it often cannot be repaired and must be replaced. For a reliable fix, consider <a href=\"https:\/\/www.fs1inc.com\/audi-ecm-pcm-ecu-engine-computer\/q5-engine-computers.html\">replacement ECMs for the Q5<\/a> from a trusted supplier that provides pre-programmed units.<\/p>\n<\/div>\n<div class=\"info-section\">\n<h2>Where the PCM Is Located and What Replacement Involves<\/h2>\n<p>The ECM on the 2014 Audi Q5 2.0L is typically mounted in the engine bay, often near the intake manifold or firewall. Replacement involves disconnecting the battery, removing the air intake duct for access, and unbolting the module. The ECM is secured with shear bolts that have locking compound applied to the threads of bolts not yet installed. These bolts must be replaced with new ones upon reinstallation. The book labor time for ECM removal and replacement is 1.4 hours. After installation, a 0.5-hour ECM relearn procedure is required using a factory-level diagnostic tool to synchronize the module with the vehicle.<\/p>\n<figure style=\"margin:22px auto;text-align:center;max-width:720px\"><img decoding=\"async\" style=\"max-width:100%;height:auto;border:1px solid #e2e6ec;border-radius:8px\" src=\"https:\/\/www.fs1inc.com\/blog\/wp-content\/uploads\/2026\/07\/2014-audi-q5-pcm-service-figure.webp\" alt=\"2014 Audi Q5 PCM location diagram\" loading=\"lazy\"\/><figcaption style=\"font-size:13px;color:#667085;margin-top:8px\">From the factory PCM removal procedure for the 2014 Audi Q5.<\/figcaption><\/figure>\n<div style=\"background:#f7f9fc;border:1px solid #e2e8f2;border-radius:10px;padding:18px 24px;margin:18px 0\">\n<h3 style='margin-top:0'>How to Reach the PCM on the 2014 Audi Q5<\/h3>\n<ol style=\"margin:14px 0 6px 0;padding-left:26px\">\n<li style=\"margin:10px 0;line-height:1.65\"><b>Remove<\/b> nut and bolt.<\/li>\n<li style=\"margin:10px 0;line-height:1.65\"><b>Remove<\/b> the filler neck with the filler tube from the washer fluid reservoir and the opening.<\/li>\n<li style=\"margin:10px 0;line-height:1.65\"><b>Remove<\/b> the bolts and the cover from the E-box.<\/li>\n<li style=\"margin:10px 0;line-height:1.65\"><b>Release<\/b> the retainers -A arrows- and remove the Engine Control Module.<\/li>\n<li style=\"margin:10px 0;line-height:1.65\"><b>Remove<\/b> shear bolts with suitable locking pliers (.<\/li>\n<li style=\"margin:10px 0;line-height:1.65\"><b>Remove<\/b> old Engine Control Module.<\/li>\n<\/ol>\n<p style='margin:10px 0 0 0'><em>Work with the ignition off, and treat the module as static-sensitive: avoid touching the connector pins at any point.<\/em><\/p>\n<\/div>\n<table style=\"width:100%;border-collapse:collapse;margin:18px 0;font-size:15px\">\n<tr>\n<th style=\"border:1px solid #d6dbe3;background:#f2f5f9;padding:9px 12px;text-align:left\">Operation<\/th>\n<th style=\"border:1px solid #d6dbe3;background:#f2f5f9;padding:9px 12px;text-align:left\">Configuration<\/th>\n<th style=\"border:1px solid #d6dbe3;background:#f2f5f9;padding:9px 12px;text-align:left\">Book Time<\/th>\n<\/tr>\n<tr>\n<td style=\"border:1px solid #d6dbe3;padding:9px 12px\">Powertrain Control Module R&amp;R<\/td>\n<td style=\"border:1px solid #d6dbe3;padding:9px 12px\">SQ5<\/td>\n<td style=\"border:1px solid #d6dbe3;padding:9px 12px\">1.4 hr<\/td>\n<\/tr>\n<tr>\n<td style=\"border:1px solid #d6dbe3;padding:9px 12px\">Powertrain Control Module R&amp;R<\/td>\n<td style=\"border:1px solid #d6dbe3;padding:9px 12px\">Q5<\/td>\n<td style=\"border:1px solid #d6dbe3;padding:9px 12px\">1.4 hr<\/td>\n<\/tr>\n<tr>\n<td style=\"border:1px solid #d6dbe3;padding:9px 12px\">Engine Control Module Relearn<\/td>\n<td style=\"border:1px solid #d6dbe3;padding:9px 12px\">SQ5<\/td>\n<td style=\"border:1px solid #d6dbe3;padding:9px 12px\">0.5 hr<\/td>\n<\/tr>\n<tr>\n<td style=\"border:1px solid #d6dbe3;padding:9px 12px\">Engine Control Module Relearn<\/td>\n<td style=\"border:1px solid #d6dbe3;padding:9px 12px\">Q5<\/td>\n<td style=\"border:1px solid #d6dbe3;padding:9px 12px\">0.5 hr<\/td>\n<\/tr>\n<tr>\n<td style=\"border:1px solid #d6dbe3;padding:9px 12px\">Engine Control Module R&amp;R<\/td>\n<td style=\"border:1px solid #d6dbe3;padding:9px 12px\">SQ5<\/td>\n<td style=\"border:1px solid #d6dbe3;padding:9px 12px\">1.4 hr<\/td>\n<\/tr>\n<tr>\n<td style=\"border:1px solid #d6dbe3;padding:9px 12px\">Engine Control Module R&amp;R<\/td>\n<td style=\"border:1px solid #d6dbe3;padding:9px 12px\">Q5<\/td>\n<td style=\"border:1px solid #d6dbe3;padding:9px 12px\">1.4 hr<\/td>\n<\/tr>\n<\/table>\n<\/div>\n<div class=\"info-section\">\n<h2>Programming Requirements After Replacement<\/h2>\n<p>Factory procedure after ECM replacement on the 2014 Audi Q5 2.0L requires a 0.5-hour ECM relearn using a diagnostic scan tool. This step ensures the module properly communicates with the immobilizer, throttle body, and other systems. Without it, the vehicle may not start or run correctly. Choosing <a href=\"https:\/\/www.fs1inc.com\/2014-audi-q5-2-0l-pcm-engine-computer-ecm-ecu-programmed-plug-play.html\">a VIN-programmed replacement unit<\/a> from Flagship One eliminates the need for that step because the module arrives already programmed with your vehicle&#8217;s VIN and software. This saves you the relearn labor time and the need for specialized equipment.<\/p>\n<\/div>\n<div class=\"info-section\">\n<h2>Symptoms of a Failing PCM<\/h2>\n<p>A failing ECM in the 2014 Audi Q5 2.0L can cause a variety of driveability issues. Common symptoms include no-start or intermittent starting problems, stalling while driving, rough idle, misfires, and reduced power. You may also notice the check engine light illuminated with codes that do not clear. Communication loss with a scan tool is another sign, as the ECM may stop responding. If you see a <a href=\"https:\/\/www.fs1inc.com\/blog\/dtc-p0603-internal-control-module-keep-alive-memory-kam-error\/\">internal memory fault<\/a> code, the ECM likely has a hardware failure and needs replacement. Transmission shifting may become erratic if the ECM cannot communicate properly with the TCM.<\/p>\n<\/div>\n<div class=\"info-section\">\n<h2>Module Trouble Codes on the 2014 Audi Q5<\/h2>\n<p>The following diagnostic trouble codes are internal to the ECM and indicate a hardware or software failure within the module itself. These codes typically require ECM replacement rather than sensor or wiring repairs.<\/p>\n<table style=\"width:100%;border-collapse:collapse;margin:18px 0;font-size:15px\">\n<tr>\n<th style=\"border:1px solid #d6dbe3;background:#f2f5f9;padding:9px 12px;text-align:left\">Code<\/th>\n<th style=\"border:1px solid #d6dbe3;background:#f2f5f9;padding:9px 12px;text-align:left\">Meaning<\/th>\n<th style=\"border:1px solid #d6dbe3;background:#f2f5f9;padding:9px 12px;text-align:left\">Full Guide<\/th>\n<\/tr>\n<tr>\n<td style=\"border:1px solid #d6dbe3;padding:9px 12px\"><a href=\"https:\/\/www.fs1inc.com\/blog\/dtc-p0603-internal-control-module-keep-alive-memory-kam-error\/\" style=\"color:#0563C1;text-decoration:none;display:block;cursor:pointer\"><b>P0603<\/b><\/a><\/td>\n<td style=\"border:1px solid #d6dbe3;padding:9px 12px\"><a href=\"https:\/\/www.fs1inc.com\/blog\/dtc-p0603-internal-control-module-keep-alive-memory-kam-error\/\" style=\"color:#1a2b49;text-decoration:none;display:block;cursor:pointer\">Keep-alive memory (KAM) error<\/a><\/td>\n<td style=\"border:1px solid #d6dbe3;padding:9px 12px\"><a href=\"https:\/\/www.fs1inc.com\/blog\/dtc-p0603-internal-control-module-keep-alive-memory-kam-error\/\" style=\"color:#0563C1\"><b><u>Full P0603 guide &rarr;<\/u><\/b><\/a><\/td>\n<\/tr>\n<tr>\n<td style=\"border:1px solid #d6dbe3;padding:9px 12px\"><a href=\"https:\/\/www.fs1inc.com\/blog\/dtc-p0605-internal-control-module-read-only-memory-rom-error\/\" style=\"color:#0563C1;text-decoration:none;display:block;cursor:pointer\"><b>P0605<\/b><\/a><\/td>\n<td style=\"border:1px solid #d6dbe3;padding:9px 12px\"><a href=\"https:\/\/www.fs1inc.com\/blog\/dtc-p0605-internal-control-module-read-only-memory-rom-error\/\" style=\"color:#1a2b49;text-decoration:none;display:block;cursor:pointer\">Internal ROM error<\/a><\/td>\n<td style=\"border:1px solid #d6dbe3;padding:9px 12px\"><a href=\"https:\/\/www.fs1inc.com\/blog\/dtc-p0605-internal-control-module-read-only-memory-rom-error\/\" style=\"color:#0563C1\"><b><u>Full P0605 guide &rarr;<\/u><\/b><\/a><\/td>\n<\/tr>\n<tr>\n<td style=\"border:1px solid #d6dbe3;padding:9px 12px\"><b>P060A<\/b><\/td>\n<td style=\"border:1px solid #d6dbe3;padding:9px 12px\">Module-internal fault<\/td>\n<td style=\"border:1px solid #d6dbe3;padding:9px 12px\">&mdash;<\/td>\n<\/tr>\n<tr>\n<td style=\"border:1px solid #d6dbe3;padding:9px 12px\"><b>P060B<\/b><\/td>\n<td style=\"border:1px solid #d6dbe3;padding:9px 12px\">Module-internal fault<\/td>\n<td style=\"border:1px solid #d6dbe3;padding:9px 12px\">&mdash;<\/td>\n<\/tr>\n<tr>\n<td style=\"border:1px solid #d6dbe3;padding:9px 12px\"><a href=\"https:\/\/www.fs1inc.com\/blog\/dtc-p0613-tcm-processor\/\" style=\"color:#0563C1;text-decoration:none;display:block;cursor:pointer\"><b>P0613<\/b><\/a><\/td>\n<td style=\"border:1px solid #d6dbe3;padding:9px 12px\"><a href=\"https:\/\/www.fs1inc.com\/blog\/dtc-p0613-tcm-processor\/\" style=\"color:#1a2b49;text-decoration:none;display:block;cursor:pointer\">Module-internal fault<\/a><\/td>\n<td style=\"border:1px solid #d6dbe3;padding:9px 12px\"><a href=\"https:\/\/www.fs1inc.com\/blog\/dtc-p0613-tcm-processor\/\" style=\"color:#0563C1\"><b><u>Full P0613 guide &rarr;<\/u><\/b><\/a><\/td>\n<\/tr>\n<tr>\n<td style=\"border:1px solid #d6dbe3;padding:9px 12px\"><a href=\"https:\/\/www.fs1inc.com\/blog\/dtc-p0667-control-module-internal-temperature-sensor-rangeperformance\/\" style=\"color:#0563C1;text-decoration:none;display:block;cursor:pointer\"><b>P0667<\/b><\/a><\/td>\n<td style=\"border:1px solid #d6dbe3;padding:9px 12px\"><a href=\"https:\/\/www.fs1inc.com\/blog\/dtc-p0667-control-module-internal-temperature-sensor-rangeperformance\/\" style=\"color:#1a2b49;text-decoration:none;display:block;cursor:pointer\">Module-internal fault<\/a><\/td>\n<td style=\"border:1px solid #d6dbe3;padding:9px 12px\"><a href=\"https:\/\/www.fs1inc.com\/blog\/dtc-p0667-control-module-internal-temperature-sensor-rangeperformance\/\" style=\"color:#0563C1\"><b><u>Full P0667 guide &rarr;<\/u><\/b><\/a><\/td>\n<\/tr>\n<\/table>\n<\/div>\n<div class=\"info-section\">\n<h2>Protecting the PCM in Your 2014 Audi Q5<\/h2>\n<ul style=\"margin:14px 0 6px 0;padding-left:26px\">\n<li style=\"margin:10px 0;line-height:1.65\">Maintain a healthy charging system;
