I have composed an extensive message and I am seeking guidance from someone. Could someone kindly provide me some advice, please? The expression of gratitude is really valued - thank you.
The 2010 Mazda 6 2.2 diesel vehicle in question has accumulated a total mileage of 150,000 kilometers. In the previous year, a situation arose where the timing chain had elongation. Upon receiving a cost estimate in the thousands, I opted to do the repair independently. Subsequently, the vehicle has shown satisfactory performance for a duration of around one and a half years.
Towards the conclusion of the summer season, the air conditioning system ceased to function well, emitting just warm air. Despite this issue, I chose to defer its resolution until the next service appointment, scheduled to take place in a fortnight, during which I intended to fix the malfunctioning compressor or clutch.
Several weeks before, the vehicle began emitting a "rattling" auditory disturbance originating from the engine compartment. This noise deviated from the customary occurrence of timing chain impact or loud rattling noises associated with their failure, instead resembling the auditory sensation of screws rotating inside a tin can. I sought advice and was informed that the issue was likely related to the air conditioning clutch. Consequently, I decided to postpone addressing the problem until the scheduled repair in a few weeks.
During our journey back to our residence today, a pronounced clunking sound was heard, resulting in a complete loss of power to the engine. After careful examination, it has been seen that the air conditioning clutch is rotating freely without any impact on the serpentine belt. Therefore, it is unlikely that the air conditioning clutch is the cause of the problem. The user's text is already academic. No rewriting is necessary.I had an expectation or desire for it to be so.
The engine exhibits rotational movement, however fails to initiate combustion, displaying a lack of any attempt to ignite. A pronounced auditory impact is observed as the engine undergoes rotation. The auditory perception of the sound is characterized by a perceived absence of compression.
Does anybody possess any insights about the potential cause or recommended areas for investigation? I have successfully established a connection with the outdated On-Board Diagnostics 2 (ODB2) system, and the compilation of error codes spans many pages. The frequency of Diesel Particulate Filter (DPF) regeneration cycles is too high, indicating a potential issue. The crack sensor range is outside the acceptable parameters, suggesting a malfunction. The Exhaust Gas Temperature (EGT) sensors are registering lower than expected values, indicating a potential problem. The intake manifold air control actuator may be experiencing a malfunction. The fuel shut off valve is exhibiting an open circuit, which may impede its proper functioning. The right front tone wheel is displaying abnormal behavior, potentially indicating a fault. Lastly, there is a malfunction in the Exhaust Gas Recirculation (EGR) circuit.
There is a significant abundance of codes.
May I kindly request your insights on this matter? Is it possible that the whole mass has perished? There have been accounts of adverse incidents involving chain failures, injector seal malfunctions, and subsequent turbocharger failures, which have been described in a manner that evokes feelings of fear and dread.
The current valuation of the vehicle suggests that its worth may be around £2,000. Consequently, I am disinclined to engage in the potentially costly endeavor of replacing components that may exceed the vehicle's assessed value.
I appreciate your assistance.
