Greetings, everyone! I am experiencing a perplexing problem with my 2018 Mercedes Vito Minibus W447. I have been experiencing random fluctuations in the temperature gauge. This weekend, I undertook an extensive 15-hour drive, and here are my observations. Temperature decline: When travelling at a constant pace of 70 mph or maintaining a consistent RPM, the temperature gauge will remain at the standard 90 degrees. However, when I attempt to activate the heater, it emits frigid air. Upon momentarily releasing the throttle or shifting into neutral on downhill gradients, the heater resumes heating, while the temperature gauge descends to just over 40 degrees and fluctuates between 40 and 80 degrees for approximately one minute. There will be a little fluctuation before stabilising around 80 degrees and ultimately reaching 90 degrees when I resume normal driving. The heater will remain warm for around 15 minutes, sufficient to provide warmth once more. The temperature rises: When travelling at a steady motorway pace (50-70 mph), the temperature gauge remains normal at 90 degrees; however, upon applying additional power, such as during overtaking or ascending a hill, the gauge exceeds 90 degrees. I would hear the fan activate. The amount of power applied, the incline of the slope, and the duration of power application will influence whether the temperature reaches 120 degrees or above. However, it will descend rapidly when I reduce the throttle. When the temperature exceeded 120 degrees on the freeway, I had a complete loss of throttle response; regardless of my actions with the throttle, the van did not respond and began to decelerate. I had to stop on the hard shoulder for a few seconds, and it was only after the temperature approached 90 degrees that I regained throttle control. I have replaced one thermostat, but it did not yield any improvement. I possess a Xentry device, and no fault codes are displayed. I lack mechanical expertise, hence I am unaware of what to observe. Any assistance would be greatly appreciated.

I will locate the boost solenoid; with the engine idling, place your hand on it. If it is functioning, you will sense a pulsing sensation, accompanied by a continuous ticking or clicking sound if operating correctly.

Electronic diverter valves, if not sealing correctly, may cause your issue without generating error messages. When utilising ista, you can instruct them to open and close. Should this not be the case, eliminate them and examine the seals.

Upon reviewing the logs and acknowledging your assertion of no hoover or boost leaks, the most probable causes are as follows: Boost control solenoid 2) Damaged diaphragm within diverter valve

Any non-runflat tires will enhance the riding quality.Experience the new PS5; Camskill offers the lowest prices and provides an £80 payback on four Michelin tires and Uniroyal Rainsport tires.I possess a PlayStation 5 on my M4.

I believe the two are interconnected. Did you get a new cap? Oil changes are rather straightforward to do independently and need little equipment; thus, I would undertake oil changes more regularly, including the oil filter, and likely proceed with one immediately. You may have dislodged debris in suspension that is affecting the oil pressure and level from the last change. Regular alterations will facilitate the elimination of residue. Owning a historic car enhances satisfaction when the owner actively engages in its maintenance and assumes duties, rather than delegating tasks to technicians. Moreover, there will be an incessant emergence of problems, alongside the financial savings you would accrue. YouTube is an excellent resource, offering several videos that provide detailed instructions on how to do any task related to your specific vehicle. The excitement of a new activity is at your doorstep. The yellow light is activated by a sensor that monitors oil pressure, while the dipstick gauges the oil level in the sump. These are interconnected but distinct concepts. Allowing the vehicle to remain stationary for many hours will provide an accurate measurement on the dipstick (I presume you own a dipstick, since you were able to assess your oil level in the last discussion).

Greetings, everyone. Is a workshop handbook available for download for a 2021 M5?

Neither is a box associated with finance. Displaying your car's registration is also inadvisable, since BMW credit has unequivocally shown its stance against any kind of modification while the vehicle is under credit.

Indeed, he is verifying if the engine is properly grounded by the earth straps.

Thank you. I will see them early next week. However, it is about a two-hour journey from my location. Is there a feasible option in London? Eastern/Central?

Is there anyone present?

Greetings! Where do you provide servicing for your performance S-Classes in London? What is the optimal location for doing pre-purchase diagnostics?

Indeed, it was completed last year.

What is the method to reach the concealed menu?

No, it is not losing any coolant; they confirmed there are no leaks or indications of fluid escape.

It is a 3-liter diesel engine; this issue has occurred previously, and I have recently retrieved it from BMW. An inspection has been conducted, revealing no leaks. A diagnostic assessment and pressure test were performed, yielding no issues; everything is clear. They also replaced the cap on my coolant to prevent any potential leakage

My 2019 BMW X5 displays an overheating warning and advises me to drive moderately, subsequently entering limp mode. Has anyone encountered this issue?

Read this; it might be useful.

Indeed! Thank you for the apology.

If trading in you will never get top price, for that you have to put some effort in and sell yourself.

The front camber is non-adjustable. Furthermore, they have not addressed the back geometry.

Thank you very much.

Greetings, Thank you; I will investigate it. Successfully retrieved information from a decoder that references Turbo.
