After market coding
Can anyone recommend a coder they used recently? I had a 2022 and a 2023 w206 both of which were coded to unlock amg menus, sports plus, and more importantly, lane keep + traffic sign assist.
I've had no luck finding anyone to code my 2025. I've reached out to a few coders who are sponsors on the forums, however they asked for 1400+ USD. I paid 250 and 300 euro for the 2022 and 2023 respectively. My previous coder is unable to offer the service due to MB further locking down the OBD environment with live stream zenzefi certs.
I understand that the current "market value" for coding services may be severely inflated due to the rarity of coders with valid licenses. However, I refuse to be extorted. The price difference is steep.

I've coded only a couple functions using a Topdon AD900BT and a Launch Elite 2.0 MB (which seem to come from the same Chinese source). While both of these OBD scanners are capable and good values, I haven't done (nor am I interested in doing) any extensive coding or experimenting with features and functions to see what I might like. As cautious and comprehensive as I try to be, there is IMO too much that could go wrong. I haven't used any of the coding services who are forum advertisers, and I am not endorsing any of them. However, I would rather pay their fee and get their expertise and support up front than to seek their service after bricking my vehicle. And I would have gladly paid their fee to be rid of auto start/stop and lane keeping assist, had that been the only avenue available.

I coded the auto start/stop permanently off. I had already done a hack on the lane keeping assist, so there was no need to mess with its coding. I also wanted to change the tire diameter since I mounted a set of A/T tires (275/55R20) in place of the OE tires (275/50R20) and wanted to correct for the 3% difference in tires diameter. However, the variant coding parameters that I thought should do this had no affect, so I restored the original configuration and let it be. I was using a Launch Elite 2.0 MB to do this. I use this scanner to check for DTCs once ever 4 - 6 weeks now. There's nothing else that I'm interested in modifying.
