    R231 2018 SL400 radio stopped responding….

    Morning all, odd occurrence in the car this morning, the radio has stopped working. The command system seems to be working fine, i just can’t get the radio to work via either the button on the centre console or through the command system itself. I just press the button and nothing happens...

    That is an interesting question, unless I’m reading too much into it. The only work the Mercedes dealer did was the injector and the new earth point. Since I got it back from them the problem hasn’t resurfaced, so it is therefore sorted (fingers still crossed). Whether the previous work that Tom...

    Morning all and happy new year! Just as a quick update I’ve had no further problems with the car over quite a number of drives now so seems to be all sorted. I still get nervous whenever I go over a bump in the road thinking it’s a misfire, lol, but hopefully that will ease over time!! All I...

    Evening all, thought I’d post an update of where I’ve got to to with my SL’s journey to sort the misfire. After another couple of attempts to fix the car proved fruitless (including changing the air intake manifold gaskets and seals and a new accelerator pedal) Tom at GT finally there in the...

    The spark plugs were changed. I don’t think he has done a smoke test, might suggest it to him. On fuel I always put in Shell V-power....it never gets supermarket file, rightly or wrongly.

    On a more positive note though (leaving aside the big engine issue!) I’ve got to say the SL400 is an absolutely awesome car. In terms of performance, level of kit you get with it versus most competitors and everyday liveability it is a no brainer choice. The brilliant blue and porcelain nappy...

    Thanks for the comments and recommendation. The error code that came up was P030022 (multiple combination misfires). I’ve had the software updated (apparently it’s never been updated since new despite full MB service history), spark plugs and coil packs changed, pin to pin tests done on pack...

    Thanks for the welcome messages. The fault arose when it was just over 3 years old typically - I’ve had it since new. I live near Harrogate and took it to a local specialist, GT service. Been in and out 5 times with a recurrent issue. I will raise a thread in the engine forum. Very frustrating.

    Morning all, I’m sure a lot of you will be able to imagine my surprise when my wife suggested I get a mid-life crisis car for my 50th birthday a couple of years ago! Anyway, I was immediately off down to the Mercedes dealer to became the very happy owner of a Brilliant Blue SL400 before she...
