{"product_id":"2026-audi-q4-e-tron-service-repair-manual","title":"2026 Audi Q4 e-tron Service and Repair Manual","description":"\u003cp\u003eThis service and repair manual is written for the 2026 Audi Q4 e-tron, Audi's battery-electric compact SUV. It is built for how an electric car is actually diagnosed rather than adapted from combustion material: high-voltage safety and de-energizing procedures first, then the traction battery and its cooling circuit, the drive unit and reduction gear, the charging system with its AC and DC paths, the heat pump and thermal management loops, regenerative and friction braking, the low-voltage supply, MMI and the camera, radar and ultrasonic sensors behind the assistance functions. Each section carries wiring diagrams, connector views, measured value tables, torque figures and step-by-step removal and installation.\u003c\/p\u003e\u003cp\u003eNo engine or output data is asserted here for the 2026 model year. The Q4 e-tron range has been offered in both rear-drive and dual-motor quattro form with more than one battery size, and the correct drive layout, battery variant and software level for your car must be read from the vehicle data sticker and control module identification before you follow any specification-sensitive procedure or order a part.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eTrims\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eBase Sport Utility 4-Door\u003c\/li\u003e\n\u003cli\u003ePremium Sport Utility 4-Door\u003c\/li\u003e\n\u003cli\u003ePremium Plus Sport Utility 4-Door\u003c\/li\u003e\n\u003cli\u003ePrestige Sport Utility 4-Door\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eTrim naming is carried forward from the most recent confirmed model year, 2024, not verified for 2026. Audi's own erWin service portal lists this chassis continuing into 2026, so treat the exact grade names and their equipment content as subject to confirmation. Which modules, sensors and actuators are physically present changes with trim and options, so match the option-dependent chapters to your build before tracing a circuit.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eKnown issues on the 2026 Q4 e-tron.\u003c\/strong\u003e One recall is on federal record for this model year: NHTSA campaign 25V638000, covering front seat belt retractors whose torsion bar may have been damaged during production. A damaged torsion bar can fail in a crash and leave the belt unable to restrain an occupant properly, and the remedy is dealer replacement of one or both front belts at no charge. No complaints are logged with NHTSA for this model year, which on a car this recent is an empty owner record rather than evidence of a fault-free one. Check the campaign by VIN before any work behind the B-pillar trim, and on any high-voltage Audi confirm the low-voltage battery state of charge and the DC-DC converter output before condemning control modules, because a weak low-voltage supply throws faults across unrelated systems and can block high-voltage system activation entirely.\u003c\/p\u003e\u003cp\u003eWritten for the 2026 model year specifically, this manual gives an independent workshop or a competent owner the same structured reference an Audi dealer technician works from, covering maintenance schedules, component overhaul, coding and adaptation, and network-level fault diagnosis. High-voltage work must only be carried out by someone qualified to do it, with the system properly isolated and verified de-energized.\u003c\/p\u003e","brand":"FactoryManual","offers":[{"title":"Default Title","offer_id":48887984259294,"sku":"AUDIQ4ETRON2026SRM","price":49.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0774\/4113\/8910\/files\/9324103401694.png?v=1788104434","url":"https:\/\/factorymanual.com\/products\/2026-audi-q4-e-tron-service-repair-manual","provider":"FactoryManual","version":"1.0","type":"link"}
