Frequently Asked Questions
Is the X156 GLA220d’s OM651 diesel engine known for any recurring issues?
Yes. The OM651 2.1L four-cylinder used in the GLA220d has a documented history of EGR valve carbon buildup and diesel particulate filter clogging, particularly on vehicles used primarily for short urban trips. The manual covers full EGR replacement procedures, DPF forced regeneration routines, and related fault code diagnostics to address these issues properly.
Does this software cover both pre-facelift and post-facelift X156 GLA models?
Yes. The X156 GLA received a mid-cycle refresh for the 2017 model year. This workshop software spans the full 2013–2019 production run, covering both the original and updated variants with appropriate model-year-specific procedures, component part references, and wiring diagrams.
Are wiring diagrams and electrical troubleshooting included?
Absolutely. The software includes complete circuit diagrams for the engine management system, 4Matic AWD electronics, 7G-DCT transmission controls, lighting, infotainment, comfort systems, and all safety circuits. Connector pinouts, wire color codes, and systematic fault-finding procedures are all documented within the electrical section.
