When my 2017 s350d was only 18 months old its started showing condensation in the driver side headlight only never the passenger side. I've been back to the dealership over 15 times now over the last 18 months heres a brief summary of what has happened:
* initially told its not an issue its normal.
* condensation got much worse after repeat calls to Mercedes UK they agreed to install silica gel packs which they did.
* 5 months later dipped beam fails, back to the dealership turns out the moisture destroyed the control unit inside the headlight.
* the above repeated three times in 18 months and after 3 new headlight units and silica gel packs installed Im right back again at the start moisture is appear and getting worse by the day.
Local dealership keep refitting the same headlight unit (same part number) with the gel packs, I get about 5 months moisture free before the cycle starts again.
Since last new head light was fitted the car was never washed (due to lockdown it wasnt been used much) so its not related to anything like that. Mercedes UK say I can only interact with my local dealership on this issue. I've asked them to raise the issue with Mercedes in Germany but they say they cant do that.
I'm not the only one with this issue, many others in the USA are seeing the exact same problem in the S550 model, to say Im p*ssed off is an understatement, I really wanted to keep this car but Im coming to the realization that this is not possible, as the car is now out of the 3 year manufactures warranty and I have to pay over £1800 every 5 months now for a new headlight.
Its not that i wouldnt spend money on it, Id gladly pay for the repair if it was a permanent solution.
Any advice on this would be very much appreciated, starting to look for a Lexus LS as I type this but Id much prefer to keep the sclass
