Used Mercedes-Benz GLS Indicator Stalk

The GLS runs across two clear generations: the first-generation X166, produced from 2016 to 2019, and the second-generation X167, launched in 2020 onwards. Indicator stalks are generally generation-specific, so a stalk from any X166 GLS should be compatible with another X166, and likewise within the X167 range. Always confirm the part number with the breaker against your registration before buying.

Both the 2017 and 2019 GLS sit within the first-generation X166 range (2016–2019), so the indicator stalk should be a strong candidate for interchange. That said, confirm the exact part number with the breaker against your registration to be sure, as minor running changes can sometimes affect stalk specifications.

The 2020 GLS moved to the second-generation X167 platform, which is a significant change from the X166, and the indicator stalks are unlikely to be interchangeable across this boundary. Route this query to the breaker and ask them to check both your registration and the donor vehicle's generation before purchasing.

Trim level does not affect indicator stalk fitment on the GLS; the stalk is a steering-column part tied to the generation and platform, not the trim. You may find cosmetic differences such as finish or button labelling depending on optional extras like the MBUX package, so it is worth mentioning your trim to the breaker so they can match the look as closely as possible.

Mercedes-Benz often shares steering-column stalks across models built on the same platform, so there is potential for crossover between the GLS X166 and GLE W166, or between the GLS X167 and GLE V167. However, this is a cross-model fitment question that goes beyond straightforward like-for-like replacement, so confirm compatibility with the breaker by giving them both registrations before you commit.

Optional packages like the driving assistance suite can add stalk-mounted controls or change the stalk's wiring configuration, meaning a stalk from a heavily optioned car may not plug in cleanly to a more basic one. This is worth raising directly with the breaker, who can cross-reference the part numbers from both donor and recipient vehicles against your registration to check for a match.
