Did the W211 have the same deficient spring-hinge design as the W202? When hinges fracture, a loud bang will emanate from the dislodged springs. Repeatedly opening and closing a boot over the years will ultimately result in significant stress and eventual fatigue of the metal hinges. I am aware that the dealership offers a repair kit for the W202 trunk

A driver may be caught off guard if the assisted brakes and power steering abruptly become heavy while navigating a corner at high speed.

You stated in the previous thread that after the incident, MB retained the vehicle for three months before returning it to you, claiming they changed the HV battery under warranty but declined to disclose particular details about the original defect (they also replaced two buckled wheels). Regrettably, this is prevalent in warranty repairs; automobile manufacturers typically do not furnish any information or evidence. On a few times, I managed to obtain a photocopy of their internal report from the dealer (Vauxhall), but they are normally disinclined to comply with such requests. However, you have had the vehicle serviced under warranty. What is the current issue? Have you lost confidence in the vehicle? Is it related to money, and can it not be eliminated without suffering a loss? Et cetera.

Indeed, it is not required for that vintage.

The drain rate appears sufficiently elevated to indicate a defective alternator diode pack or alternator regulator. I experienced a comparable rate of discharge and anticipated discovering defective diodes. Following a considerable effort to remove the alternator, I delivered it for refurbishment, where it was confirmed that the diodes tested well. I requested that they replace the regulator while it was in their possession, and to my astonishment, this resolved the drainage issue. I recommend seeing a vehicle electrician to assess your alternator. If you can access the alternator conveniently and own a digital multimeter, you can conduct the test independently

I possess a Sealey cordless tire inflator, a cracking tool, and it includes two batteries and a charger. Additionally, I possess a Noco Boost jump pack, which functions as a torch and includes USB ports for charging devices such as phones.

No battery alerts have occurred subsequently. However, I will assist this individual as soon as the weather is not very chilly outside. 😂 I opted for the 10A to avoid an 11-hour charging delay.

The battery number on my service sheet is MA001 982 81 08/26, suggesting it is an OEM Varta 80Ah AGM battery; but, it may be from any brand, so I will attempt to inspect it at some point. I believe it will be challenging to make a claim, particularly if it can be sufficiently charged to pass a battery assessment. I can envision them merely recharging it and exclaiming, 'See, it's functioning!' so rendering my trip to NW London, where I no longer reside, futile. There may be a two-year guarantee, potentially less than the manufacturer's, presumably to account for the part number being associated with several vendors.

Thank you, everyone. I believed at the time that the auxiliary capacitor was responsible for the start/stop function (I am uncertain about the specific roles of each component, to be honest), and as I was indifferent to that aspect, I neglected it. 😂 I will examine whether there is any warranty on the battery, which was installed during a service at a dealership. I am uncertain if the service sheet will provide relevant information, but I will explore further. I am unaware of the brand, to be honest, as I have never removed the cover. A typical travel exceeding 45 minutes sufficed to mitigate that warning for several weeks, and this remained true even lately. Recent occurrences of the notice appearing post-drive have led me to suspect a phantom drain. However, it currently appears that battery situation is more probable. The current plan is to get a Noco 5 charger, fully recharge it, and assess its status. The battery may have been defective from the outset. An AGM battery, even under less than ideal conditions, should last longer than 2.5 years.

Interestingly, it commences seamlessly at 11.7 volts. Yesterday, when I initiated it after a period of inactivity lasting a couple of weeks, it required more cranking; while it did not exhibit difficulty, the process lacked the expected ease.

Less than halfway through the drive, the IB decreases from approximately 8 to around 2.x and is rather stable thereafter. BN has scarcely grown, although it typically exhibits a significant gain after charging. Am I correct in assuming that if the alternator is defective due to inadequate charging speed, there would be additional symptoms present? Am I correct in assuming that if the auxiliary battery or capacitor were functioning effectively, there would be a distinct warning and the battery statistics would appear more favourable? Is it unusual or typical for an OEM battery to be depleted after 2.5 years, considering it operates in a suboptimal environment due to occasional use? I no longer believe I am experiencing a phantom drain, as the device does not seem to charge effectively, and warnings reemerge after hours rather than days. What are our thoughts? 😄

Greetings, everyone! I require assistance in diagnosing the issue with my battery. I am receiving the persistent yellow battery warning in the vehicle, which occasionally dissipates after a thorough drive but often reappears shortly thereafter. The battery endures a challenging existence, as the car is infrequently driven, resulting in limited time spent in a charged state. I apologise for the information overload; nonetheless, I am providing a timetable and battery statistics. A new primary battery was installed at Mercedes 2.5 years ago, and all is functioning well. A few months later, the start/stop function became dormant once more; nevertheless, everything else was functioning OK, and I was indifferent to the start/stop feature, so we continued as usual. Approximately one year ago, I experienced an event in which I left the vehicle parked on a frigid night with the battery warning illuminated, resulting in a failure to start and necessitating a jump start. Intermittently, particularly in winter when the battery is depleted, the vehicle displays a "collision assist not operational" message, which resolves autonomously after the battery is recharged. A few weeks prior, I drove the car for approximately 40 minutes, and several hours later, I received a battery warning. I took it out once more for an additional 20-30 minute trip, and there were no concerns with an extended interval before the next drive. Yesterday, the battery alert illuminated, prompting me to drive the car for 40 minutes. Several hours later, the battery warning reappeared... Operated the vehicle for an additional 20 minutes, and the warning reappeared later that evening. Operated the vehicle again this morning for 25 minutes and documented the battery statistics, which appeared suboptimal. Battery statistics: Prior to initiating the vehicle (by pressing the start button once to activate the radio and other systems) with a battery warning, I am uncertain whether the -15A reading is typical.
