DIY Repair Guide: B2699 on Subaru Xv
The throttle body on the Subaru Xv can be cleaned without full removal. Use a clean rag and throttle body cleaner spray with the engine off and cool. After cleaning, an idle relearn is mandatory: disconnect the battery for 10 minutes, reconnect, and allow the engine to idle for 10 minutes undisturbed.
Preventing B2699 on the Subaru Xv
For turbocharged Subaru Xv models, allowing the engine to idle for 60–90 seconds before shutdown after hard driving reduces turbocharger heat soak and prevents the coking of oil that blocks VVT galleries — a known secondary trigger of B2699.
Frequently Asked Questions — Subaru Xv B2699
A: Yes. Any stored fault code — including B2699 — will cause an automatic failure in most OBD-II based emissions tests. The code must be resolved and the vehicle must complete a full OBD drive cycle with no new codes before the test.
