Remember, this is permissible only if your vehicle is on a driveway or private road; leaving the engine running unattended on a public road is prohibited.

I completely concur; I possessed a PHEV for two years and encountered recurrent Hybrid System and Engine Malfunction issues that intensified with the vehicle's age. This occurred twice when I initiated it in the dealership lot after the repairs were purportedly finished. Moreover, transitioning from an electric vehicle motor to an internal combustion engine may occasionally result in a jolt. This would continue to occur despite all the updates.

What is regarded as high mileage for the N57 engine? Can most issues be prevented by regular maintenance? I intend to acquire an asset valued at approximately 60,000 and likely sell it in a few years when it reaches 100,000. Is the 57 engine unreliable, or is it merely more susceptible to problems than the 47? Thank you

Thank you for the information; I was unaware that they transitioned to LEDs in late 2017.

How do you determine the fuel efficiency of the 420i? I contemplated acquiring it, but the majority of reviews indicate that they are largely comparable, with the diesel variant offering slightly more power and around double the fuel efficiency. I am now inclined towards the 6.

Indeed, it aligns with my understanding of the xDrive; hence, I will certainly opt for the standard option. Thank you!

M Sport Plus, preferably with an automatic gearbox, however I will accept the M Sport variant with Harman Kardon speakers. Is there anything else I should specifically be seeking?

Thank you for the counsel. I am eager to test drive both models; however, they are difficult to locate locally with the appropriate year, specifications, and miles. I prefer not to test drive a vehicle in which I lack genuine purchasing intent. I will likely travel south to procure one and return if everything is OK. In addition to evident concerns such as knocks or wobbles, what specific indicators should I observe or auditory cues should I heed during the test drive to identify potential faults with these vehicles?

Thank you for your response. The prevailing consensus indicates that the 430D is a more sophisticated vehicle. Opinions on xDrive versus regular drivetrain?

Greetings everyone, I am purchasing my inaugural BMW next month and am deliberating between a 2017/2018 420d M Sport and a 430d M Sport. I have viewed numerous YouTube reviews and perused a considerable number of online content, yet I remain conflicted. I desire excellent fuel efficiency, hence I am committed to diesel; yet, I also seek an exciting driving experience, as I will predominantly be on rural or secondary roads. I intend to perform most of the maintenance on the vehicle myself; wish me luck, as I have heard it can be quite challenging. My present vehicle has a 2008 2.0L petrol engine producing 150HP, hence either alternative will represent a significant enhancement. What is the fuel efficiency in miles per gallon (MPG) for mixed out-of-town and B-road driving? Is there a substantial distinction between the 2.0L and 3.0L engines? Is the 420d enjoyable to drive, or does the 430d provide a significantly superior experience? What other information should I be aware of that may not be covered in reviews or general information? I anticipate your insights.

I acknowledge your concern regarding high mileage vehicles. Considering that you are examining 15-year-old vehicles, I believe that 100,000 miles is not excessively high, averaging approximately 10,000 miles per year. The general condition of the vehicle is crucial. A comprehensive service history is vital, ideally accompanied by a limited number of prior owners. If it includes it and all the documentation regarding replaced parts, it indicates that it has been well maintained. Best of luck!

Thank you! I will certainly refrain from using those Chinese tires. I do not want conventional 'tank slappers'!

I am now using Bridgestone tires on my 2016 SLK 300 AMG Sport. They are satisfactory. Relatively quiet and fairly comfy. Nonetheless, I remain unconvinced about their grip levels, especially under wet or slippery road conditions. I recently had a failure of the NSF wheel speed sensor, which disabled the ABS, stability control, and many other unexpected functions, including an alert to reduce speed when I was parked and attempting to raise the roof. Had to deactivate the engine, re-engage the ignition and raise the roof using the batteries. Following a period of rainfall, I exited a roundabout at 3 o'clock, exhibiting a degree of overzealousness with the accelerator. An spectacular 'tank slapper' occurred, which I barely managed to control. No. 2 Son (GR Yaris) advocates for Michelin Pilot Sports; nonetheless, what suggestions do you have for optimising traction? As a lifetime automotive enthusiast, I now drive seldom, averaging around 5,000 to 6,000 miles annually. All feedback is appreciated.

The back cable seems OK; however, the bolted connection inside the battery compartment was rather soiled, which I have since cleaned. The engine bay side seems acceptable. Is there a method to test the cable for potential faults?

Measured from the positive terminal to the engine bay grounding point on the left side. I believe a weak connection between the rear battery and the engine compartment. I also investigated potential grounding issues but only examined the engine to chassis ground strap owing to the onset of darkness and cold weather.
