Folks... I have a C300 and amateur question about the cigarette lighter socket in the front of the car.
It says "12v/0.15A" Does this mean if I plug a Cigaratte adaptor for USB charging that exceeds 0.15A, its going to go pop?

Also I noticed that the fuse for the cigarette lighter has infact "gone" already.
It is a 15a fuse it seems but its labelled "15s".

Reading up on some forums, it seems this is something to do with silver plating?

Question is where to get these without having to go to the dealership...
Or am I ok using bog standard 15a fuses that I could get from halfords and the like....

The manual does say that fuses in the engine compartment and the boot (where the cigarette lighter fuse is located) should be replaced with the "s" variant.

Would appreciate the insights of OCUKs seasoned and experiences Mercedes drivers. Thank you!

I thought it was a daft question till I Googled it. Profound. Some say silver, others say it stands for slow acting. A normal fuse apparently works but the language in the manual would condemn you for doing so. Good luck :p
 
Well this is what has me perplexed about this fuse, not sure what makes this "S" type any special...
Would appreciate any advice or experience from other drivers who have come across this.

Thanks.

I don’t have any experience but I don’t buy into the silver element. I can understand why it would require a slow blow fuse, as a cigarette lighter heats up an element by drawing a load of current and it would draw that instantaneously hence a slow blow fuse. What doesn’t make sense is the fuse is 15A and you say the maximum draw of the lighter is 0.15A? I would expect a cigarette lighter to take a lot more than that.

With that said, I used a cigarette lighter charger on my E43 many times to charge my and my wife’s phones without any issues.

If you are that concerned why don’t you use the USB sockets under the armrest?

Well on the cigarette lighter cover/cap it says "12V/0.15A", confusing for me. Agreed a cigarette lighter should be able to take much more.
Here is the diagram, https://fusecheck.com/mercedes-benz/mercedes-benz-c-class-w205-2015-2019-fuse-diagram
Fuse number 446 I believe which is rated at 15A.

Yes I did considering using the under arm socket but I wanted to have a short travel distance of cable from the cigarette lighter to the phone holder mounted into the central vent, rather than the cable travelling from the arm rest, across the the command knob thing etc.

You are right it’s a 15A fuse which doesn’t make sense. It doesn’t list anything else on that circuit so it’s odd to limit it to 0.15A. As you are not using a cigarette lighter then a normal fuse will be ok, there’s no reason you need a slow blow fuse to run a charger for 0.5A. It won’t blow the fuse but I’m still bewildered why 0.15A.

Fair enough, I wouldn’t want a cable running across the center console either.

edit: I just went out to check my car and mine has a USB port where the ciggie lighter was in my E43 but the ciggie lighter cap in the rear says “MAX.15A” which makes sense so maximum 15A

Thank you Bear, I perhaps misread MAX.15A as being 0.15A, so that solves that mystery then. Thanks for taking the time to check it.

So now I just need to figure out this "silver" designation and if it really does make all the difference....

Will give Mercedes a call tomorrow.

I’ll be arriving sideways! :)


EDIT: WOW! £1890 worth of work carried out!

Ignition coil cylinder 1 faulted 10 times internal fault with coil pack

Engine control unit requires software update for miss fire issues

Osf strut top mount noisy and nsf

Both front caster arm bushes split

Transmission ground cable corrosion ( can cause engine miss fires )

The Caster Bushes are on back order, but I can collect the car later on today.

WARRANTY WINNING! :D :D :D

and the engine light is back on, misfiring like crazy! :(

Beginning to think this car is cursed
 
Cheers,
I hope this isn’t failure 2 of 8 for the coil packs. Will ask if they replace them all


I just started it to see how it ran. The usual v8 start wasn’t there at all. Then it reeked of petrol....
 
Well I did it... bought a shiny 70 plate A35 AGM Premium in the digital white paint. Pick it up Friday so I can share a pic or two if anyone would like that. :)
 
I have hardly driven my car lately, but today when driving into the office I looked around my car and thought this ain't bad. Yea so it's a 250d and not a V8, or even a petrol for that matter, but that aside I still love the interior of the merc and adore the audio system. Small things.... Still want a c43 though....

I had a 2014 c250 before the E63, loved the 250’s interior, so comfy and amazing sound system. I used to look forward to wafting down to oxford and 50mpg.

now I clatter down noisily at 24mpg
 
Not sure what to do next; nearly had the A45 4 years now - initial term of the agreement, there's some equity left in it. Not sure whether to purchase fully, or change it up and get something a bit more daft!

Get something daft, its worth it. I work from home so I only use my car for enjoyment and every time I jump in it, its hilarious as its so outrageously fast and the v8 noise is epic.

Yea that's what I fancy - same boat as you as I'm working from home, so drive very little. Looking at c63, who knows! Not sure whether to go absolutely bat**** and go nuts.

I was thinking exactly the same thing a few months ago, I wanted a v8 but didnt know if I could justify it to myself. In the end I thought **** it and bought an E63S and havent regretted it.

To be honest the car is an 'ok' blend of power and eco, but not enough in either to be great if that makes sense?
