I adore my Mercedes, however it seems to resent me! Cleaned weekly and polished meticulously, I Installed a new LCD screen and replaced the tweeters with Focal units, installed Brembo discs and pads; nevertheless, the door mirror LEDs have ceased functioning. Invested half a day attempting to remove the mirror cover, only to discover that some individual had inserted a screw at the base of the case to secure it. Repaired LEDs and replaced the casing. I have changed the speaker grilles four times since acquiring the vehicle: twice on the driver's side and twice on the passenger side, which were damaged by the seat belt. Ordered and replaced broken door card clips, changed the intermittent alternator and battery, and replaced the alarm module that caused the battery to discharge weekly. Visited the supermarket last week; upon exiting, the vehicle failed to start. After few attempts to troubleshoot, I contacted the RAC and endured a five-hour wait. Identified the issue as originating from the transmission electronics box; procured a second-hand replacement which I installed, functioning for a few days before failing to start. I removed the center console once again and discovered that the circlip securing the selector to the gearbox, which I had reused, had fallen out. A replacement costs £15, and I can resume driving. However, on a drive today, I noticed that the door mirror LEDs had ceased functioning.

I excessively prioritize maintenance; I perform oil changes on my vehicle every 6,000 miles. However, I have recently adjusted this to every 11 months, approximately 35,500 miles. I have also serviced the gearbox and differential and addressed a differential leak. Additionally, the video he referenced indicates that the cooling system is identical to that of the M5 and M6.

It is the second video featuring M4 on a ramp.

The M4 included several components from the M5 cooling system of the F series. Here is an excellent video with a technician discussing the M4 upon its release from manufacturing; it is one of the most informative videos I have ever seen.

My M4 has cooling fans that remain operational after the engine is turned off, particularly when it has been in sport mode, since they immediately activate in that mode or sport +.Approximately 10 minutes, but more accurately 5 minutes; I have never seen any battery issues with the lithium batteries.

Possibly the brake light switch? However, I am uncertain, to be honest.

Does the starter produce a sound? Does the starting relay emit a clicking sound? When you turn the key, do you measure 12 volts at the starter's exciter terminal?

It seems that there may be an issue in the strut tower region, maybe indicating a problem.

It is likely most convenient to wait in line for the starting exciter.

Audio files in MP3 format can be transferred to an SD card on your PC, which can thereafter be inserted into the SD card slot in COMAND. You can organise the MP3 files into folders. You will want either a PC equipped with an internal SD card reader or an external USB card reader. Upon inserting the SD card containing the MP3 songs into the COMAND device, you may either play the music directly from the SD card or transfer the MP3 files to the Music Register on the COMAND's internal HDD. The HDD in COMAND NTG4.5 possesses a total capacity of 100 GB, with 10 GB designated for the Music Register. However, be advised that transferring mp3 files from the SD card to the internal Music Register is a time-consuming process.

One could obtain the tune from Velocity AP and request the removal of the DEF and DPF in the tuning process.

Automatic or manual gearbox?

Everything is functioning adequately without it, thank you.

Thank you one again.

Thank you.

Thank you. It seems I do need it; I will proceed with the exchange.

Can someone clarify what this is and if it is necessary for me? I have recently substituted the central console, and the new unit lacks the feature included in the previous one. Thank you.

Indeed, I concur; it is also a dashboard warning light.

A compression test is necessary to determine whether the rings are defective. If you share your location, someone may be able to suggest a garage to do the compression testing.

If that were accessible, it would be excellent; but, primarily since the car is high specification, I need a technician with expertise in Mercedes to do a thorough inspection and ensure it is in optimal operational condition. I want to avoid spending a substantial sum just to discover that £3000 in repairs and maintenance is required three months later. I enquired if there are any countrywide inspection services of such kind, distinct from conventional RAC or AA inspections.

Greetings, I am considering acquiring a C63 AMG (W204) in the next weeks and months. It is only a matter of identifying the appropriate option when the occasion arises. Regardless of the automobile I choose and its aesthetic appeal, I still like to have it inspected prior to purchase. I anticipate purchasing a vehicle privately and lack clarity on my requirements; thus, I want an expert to do a thorough examination to assess its value. I have seen that firms such as RAC and Click Mechanic provide a general service rather than a specialised one. I assume there are model-specific aspects to consider while inspecting a C63, which are crucial to identify, and I believe the RAC may overlook these details. I am enquiring if there are any countrywide professionals available to do a pre-purchase examination, or whether I must seek local services in the region where I want to purchase the vehicle.

I would be wary of the components, particularly the sensor. Attempt to interchange the sensor from one side to the other and see whether the defect relocates, after verifying the live data.
