I was unaware that Formula 1 vehicles used diesel fuel.

I get your inquiry; nonetheless, I am uncertain about how screen size influences the conclusion, to be honest. I am unable to provide a response on the hydraulic lifter oil treatment. You are mistaken; the OM651 is inherently loud. I provided a recognized answer based on my expertise. Wishing you success in your decision-making. 👍

I recommend including Miller's 'ECOMAX' or Hydra's 'CEBO,' since both will enhance combustion efficiency and reduce noise in a diesel engine. I use the CEBO due of its cost-effectiveness while purchasing 5 liters. The OM651 engine is notably reminiscent of a tractor at idle. As winter approaches, I strongly advise using it at a dosage of 1ml per litre of gasoline; 2ml per litre will not do any damage. I have used it for around 15 years and endorse it unequivocally. Your performance will be enhanced with the additional cetane. It resembles the use of premium diesel. I hope your noise is not indicative of a timing chain rattling, but you are only at 43,000 miles, if I recall correctly. Anticipate the detractors, labeling it as fraudulent nonsense. 😂

It seems that the mass air flow sensor may be malfunctioning; several discussions here reflect the symptoms you are encountering.

Which automobile is it? Is it not possible for it to be the 2008 CLC? I changed the 12 Ah auxiliary battery in my W222 twice due to the same problem code. The old battery exhibited optimal voltage while unloaded; however, when attaching a 21 W bulb, the voltage decreased by several volts (precise values are not recalled).

I believe that diesel engines are subjected to various testing protocols nowadays.

Indeed? Thank you, I hate the speed alarms.

I have had a GLC coupe for the last two years, which has sports suspension. I replaced it with an Audi SQ5 and can unequivocally state that the Audi surpasses the GLC in performance. If comfort is a priority, I would seek a Mercedes equipped with air suspension, since the Mercedes sports suspension is designed for handling rather than comfort, in my humble opinion. The E400d is classified as a saloon or coupe. I do not see any more riding height, to be honest. I would avoid the engine since it is susceptible to cam follower and roller bearing problems.

The vacuum test is inferior in accuracy compared to the pressure test, which, when combined with dye, is more effective in identifying leakages.

Could you have disrupted anything else? Is it possible that the air filter is loose and vibrating? As said without being present? However, it does not resemble a banging engine.

Diagnosing wheel bearings may be challenging. Noise is often present without play, which worsens when roughness is perceived, followed by further deterioration and eventually observable play. During the journey, upon hearing the humming sound, gently engage the brakes, accelerate, and maneuver away from the straight path. Should the loudness alter during any of those operations, it is probable that a wheel bearing is deteriorating. Which one thereafter poses the difficulty!

Purchase them from Mercedes to ensure their authenticity and compatibility (and they will break similarly to the previous ones 🙂 )

Numerous diagnostic scanners and some applications will code or register a fresh battery.

A fault code scan may elucidate the issue. You may also attempt the reset by disconnecting the battery for 30 minutes. Additionally, have you registered or coded the new battery to the vehicle?

Part # X pertains to Mercedes Benz. Extract the obsolete brake pads and conduct a comparison.

Conversely, upon purchasing the same vehicle as you did just over a year before, I violated the FMBSH and sought assistance from my local independent mechanic. The labour rate at MBS is more than fifty percent lower than that of my local primary dealer, and I have consistently received excellent service, quality repairs, sound advice, and occasional favours from them. I had a suboptimal experience with the main dealer when the E400 had a recall last year; the process was excessively prolonged, and they left the driver's window open during a thunderstorm, offering no apologies, just a few paper towels to absorb the water inside. It is a chaotic environment for the three-year PCP service plan operations.

I apologise for my error; I believe your feedback pertained to a Main Dealer. My vehicle was taken to an independent dealership.

The dealer offered to reduce the value of my car by £1200 if I did not plan to have a B service performed. I chose to utilise my service plan, which ultimately cost approximately £850.

Consider attempting this alternative; it offers a more comprehensive solution and may prove effective.

I recently sold an AMG that need servicing. My curiosity has increased following the completion of the program. It was effortless for me since it was included in a service plan.
