W205 Door Handle LED's and Aux Battery.

[Treborsweet]

Hi all,

Couple of issues, had the car 8 months (2017 C250) with Mercedes extended warranty.
I changed the reverse bulbs to led as they were normal bulbs, while every other bulb in the car are led (headlights & tail lights etc) might be coincidence but i'v noticed that 2 of my door handle led bulbs have dimmed to a violet colour (drivers front & passenger rear), could this happen by putting in leds?

Also my start/stop doesn't seem to be working, didn't work during winter, then worked a couple of times in the last month, now nothing at all again, would these items be covered under warranty? could it be the start/stop aux battery/capacitor?

Put the car on a CTEK overnight and it will start working again; alternatively, give the car a good run.

Merc warranty (assuming thats the warranty) wont cover for faults caused by non spec parts - ie the led upgrade.

I dont see why stop start will be related to the bulbs - so let merc check.

I would say a battery may not be covered by warranty.

Has been on a good run, no errors regarding aux battery on the dash.
Going in for service very shortly. So i will mention it.
