Mercedes GL-Class Workshop Manual FAQs

What's included in a Mercedes GL workshop manual?

Each GL workshop manual includes step-by-step repair procedures, maintenance schedules, torque specifications and diagnostic trouble codes — the same factory-level information used in professional workshops. Most also include full wiring diagrams (see the product page for exact contents).

Which GL generations (chassis codes) do you cover, and is it the same as the GLS?

We cover both GL generations: the X164 (2006–2012) and the X166 (2013–2016). In 2015 the GL was renamed the GLS — the X166 continued as the GLS — so for the later model see our GLS-Class manuals. The chassis code is listed on each product page.

Which GL models and variants do you cover?

Our range spans the full line-up — the GL320, GL350, GL420, GL450 and GL500, in petrol and CDI/BlueTEC diesel forms, including the 4Matic all-wheel-drive models, plus the AMG GL63. The exact variant is listed on each product page.

Do the manuals include GL wiring diagrams?

Most of our GL repair manuals include complete wiring diagrams — covering the electrical system, ECU pinouts, sensor locations and component layouts for accurate electrical diagnosis. Coverage can vary by model and year, so always check the individual product page for the exact contents of each manual.

What formats are available and how are they delivered?

Most GL manuals are supplied as instant-download PDF, with selected titles provided as HTML-based manuals. The format of each title is clearly indicated on the product image and within the product description, so you can confirm exactly what you'll receive before purchasing. All formats are delivered instantly after checkout, with lifetime access on any device.

Which GL engines are covered?

Our GL manuals span petrol and diesel powertrains. Petrol coverage includes the M273 V8 and the 4.7L M278 biturbo V8 (GL500). Diesel coverage includes the OM642 V6 (GL320/350 CDI and BlueTEC) and the OM629 V8 (GL420/450 CDI); the AMG GL63 uses the 5.5L biturbo M157 V8. The exact engine is listed on each product page.

Do you cover petrol, diesel and AMG GL models?

Yes — petrol, CDI/BlueTEC diesel and the AMG GL63 are all covered across the range. If you can't find the exact GL variant or year you need — including the later GLS and all-electric EQS SUV — please contact us and we'll do our best to source it for you.
