I have a 2020 Mercedes AMG GLC43 and I’m honestly getting annoyed with the 80 and especially the 120 km/h warning beep. I talked to a guy online who said he can code it out remotely for around ₹35k, but a local German car workshop in Ludhiana advised against it after checking deeper into the Mercedes system.

They told me it can potentially create issues with OEM ECU coding/authentication, STAR diagnostics, future dealership visits, and maybe even insurance claims if something major happens. Another guy says it’s completely safe and many people already do it.

Now I’m confused whether this is a normal coding job or something that can actually mess with the car long-term.

Has anyone here actually done this on a newer Mercedes/AMG? Any real-world issues later? Did Mercedes detect it during service? Also what’s the realistic price for this kind of coding in India?

Would appreciate genuine advice from people who’ve actually experienced this instead of just sellers/coders.
