MOTOR EA211: DIAGNÓSTICO E REPARO COMPLETO - APRENDA A SALVAR O MOTOR DO FUTURO!

Sign up for the free course "The engine of the future" on July 7, 8, 9 and 10: https://allventoeducacao.com/motor-do... This video presents a complete analysis of the EA211 engine, the predominant engine in Volkswagen and Audi vehicles manufactured from 2014 onwards. Considered the "engine of the future", the EA211 equips models such as the Audi A3, Golf MK7, Up!, Fox and Tiguan. The Allvento workshop, specialized in Volkswagen and Audi in Curitiba, Paraná, demonstrates essential diagnostics and solutions for the most frequent failures of this engine. CASE STUDY: AUDI A3 8V 2014 Symptoms presented: Lack of power Excessive smoke Electronic diagnostics identified: Weak battery Injector failures Accumulated combustion failure Carbonized spark plugs Root cause: Significant accumulation of oil inside the cylinder COMMON TECHNICAL PROBLEMS IN THE EA211 Lubrication System Oil accumulation: Indicates failure in the scraping system, causing excessive consumption and smoke emission Oil scraper ring: Three-component system (two thin rings + one spring) responsible for removing oil from the cylinder walls Side scratches on the cylinders: Aggravate sealing and scraping problems Related Problems Turbine carbonization: Consequence of excess oil in the cylinder, not necessarily a turbine defect Oil and water leaks Injection problems Carbonization generalized REPAIR STRATEGIES VS. REPLACEMENT Replacement Costs National engines (manufactured in São Carlos): R$ 12,000 to R$ 28,000 (average R$ 20,000) Imported engines (e.g. 1.4 TSI 140hp gasoline): More complex replacement due to specific codes Advantages of Repair Technical feasibility: EA211 engine has reconditioning and repair available Economy: Especially for imported engines without a direct replacement Technical knowledge: Allows for proper selection of components (flex vs. gasoline pistons, crankshaft adjustment, turbine selection) Risks of Used Engines Uncertainty about maintenance history Repair shop's responsibility in case of failure Customer dissatisfaction CRITICAL TECHNICAL SPECIFICATIONS Differences between Versions Compression ratio: Varies between flex and gasoline versions Crankshaft: Adjustment of factory by ultrasound, five bearings available Valve control: 1.4 TSI 140hp engine does not have a camshaft variator Grinding Process Specific adjustments for different configurations Specific torques and specifications Assembly and adjustment tips TECHNICAL TRAINING Allvento offers the world's largest online training for Volkswagen and Audi, including: Review of knowledge during practice Free course "The Engine of the Future" (July) Practical disassembly of the EA211 engine Crankshaft adjustment process CHAPTER 1 WITH TIMELINE 00:00 – Introduction: context of Volkswagen and Audi engines 00:25 – EA211 engine: present and future of the brand 00:46 – Applications of the EA211 in the VW and Audi lines 01:25 – Audi A3 case: symptoms of lack of power and smoke 01:45 – Diagnosis: oil accumulation in the cylinder 01:57 – Oil function and scraping system 02:00 – Assessment of sacrificial materials 02:22 – Probable causes: inadequate lubrication 02:40 – Demystifying the "disposable engine" 03:22 – EA211 features and ease of repair 03:50 – EA211 frequency in the workshop 04:10 – Technical details: gearbox, wiring, coils 05:00 – Customer's decision to repair 05:40 – Spark plug condition and scratches on cylinders 05:58 – Scraper ring operation and failures 06:33 – Costs: domestic engine vs. imported 06:50 – Common defects and preventive maintenance 07:20 – Economic justification for repairs 07:50 – Risks of used engines 07:59 – Secrets of EA211 reconditioning 08:45 – Invitation to a free course 09:20 – Practical demonstration of disassembly
