I'm trying to find the engineering number (different to part number) for a rear view mirror assembly for a vehicle with lane keeping assist / traffic sign recognition for a 2016 L405 / L494 - earlier or later versions are electrically different, as are high-beam assist (only) variants.
The number is stamped into the exterior casing, facing the windscreen and will start with a 'G' - for example GPLA 17E678 AA
NA variants are not compatible with RoW (standard... ;) )

Any help appreciated
 
Thanks for that - it's an earlier MY they're arguing about and NA spec (different hardware) but there is GK52-17E678-GC mentioned... the initial 'G' indicates 16MY (which has a different CAN address to earlier MY's)... We've had several in work recently, but all 17MY onwards, which are different again!
The engineering number is used on fleabay by the breakers as it's stamped on most parts, which saves them having to cross reference the parts catalogue - I'm looking to upgrade my new(er) L405 with traffic sign recognition & LDW, not that I need it, 'just because I can' ;)
 
I have built in lane assist, it's called COAC
Are you on the 'Hendon List' as well?

Driving aids are just that, not a replacement for driver attention and driving appropriately - as it says in the online or paper manuals for vehicles with 'assistive technology'.
Just because it's there doesn't mean you have to use it - as many drivers choose not to.

In my case, it's a technical exercise rather than a need / want.

Bemoaning the relentless progress of technology and your opinion of it's effects on driving skills, or the loss of them probably won't have any effect other than making you feel better - mainly due to the site demographics being skewed to the older, less equipped vehicles and their keepers.
I have noticed that comments and opinions along the line of yours seem to appear often when new members ask questions about newer vehicles and their technology - possibly part of the reason they don't hang around?

Possibly, it is 'more to go wrong' - but here's the thing, there are less issues with newer tech given the density of it compared to older vehicles with a single number of addressable systems. L405's have up to 129 addressable systems, many work transparently and faultlessly, some do so but have programming issues or unintended consequences - not 'something going wrong' but the implementation didn't fully foresee certain usage cases, often easily fixed in software (after the inevitable testing delays), a case in point is early L319's throwing a restricted performance error when left-foot braking whilst still applying throttle input, something that was never fixed on L322's but was a simple calibration update on L319.

Lane assist actually encourages the driver to not pay attention. But don't worry, soon you will not be allowed to drive, the car will do it all.
