My aim is to decarbonise the cylinder head, replace the malfunctioning swirl motor, substitute the oil cooler seals (despite the presence of purple seals, it is prudent to address them), replace the leaking AC condenser and clean the DPF. I am not providing a comprehensive photographic tutorial; if you lack the requisite skills, consider hiring a professional. However, if you wish to do it and possess the necessary competence, numerous resources are available on this forum and YouTube. I am undertaking this to identify any potential difficulties and address any enquiries that may arise, if possible....and might pose some enquiries of my own. This was intended to commence in the new year; but, the weather has been excessively chilly, prompting me to begin today. The forecast predicted dry conditions; it was inaccurate!Despite having the entire day, I only accomplished approximately four hours of work amidst the intermittent showers. I spent half an hour attempting to remove the DPF, which I have yet to accomplish. I will initiate a separate topic with this issue. This occurred around 9 o'clock this morning.Only the cover has been removed.

Thank you for your responses. It is the whole hybrid three. I utilised chatGPT, and it indeed resembles the typical sound emitted by the inverter. It seemed peculiar to me due to its intermittent nature. At times, it is inaudible during a drive; at other instances, it occurs sporadically, although it can also be constant, as demonstrated in the video.

Which model of Sportage do you possess? It resembles the noise occasionally produced by an electric motor.

I understand you stated it is not wind noise, yet it distinctly resembles the sound of a window that is not fully closed.

I experience tinnitus, so if the sound is high-pitched, it may be obscuring it.

I recently purchased a 2022 Sportage with 25,000 miles from a Kia dealer. I have seen a sporadic whistling sound. It is not wind noise; it typically occurs at moderate speeds, particularly while parking. This issue typically does not occur upon initial ignition but arises after driving for several minutes or, at times, a significantly longer duration. Does this appear to be typical? I am unfamiliar with hybrid systems. Link to the video is provided below. Whistling occurs throughout the majority of this video. It typically does not persist for this duration; it is generally more sporadic. I would very appreciate any feedback you may provide.

It is surprising that you have not heard of them.

DRW in Liverpool mostly specialises on M automobiles but has an excellent reputation for their cutting services; a quick Google search will confirm this.

Greetings

It is advisable to post that in a different thread.

Hello everyone, could someone direct me to a reputable independent establishment in North West England? Situated in Liverpool, hence in close proximity. Requiring replacement of the timing chain and servicing of the automatic gearbox. Thank you.

I will investigate which aftermarket rims are forged and which are cast. Numerous aftermarket alternatives exist. Thank you for the advice regarding the springs; I will investigate more. Do you know if there is an official online parts page for Mazda?

I comprehend the dilemma; I experienced it as well. The F damper shocks were superior to the Koni's for my preferences; yet, despite the original shocks' excessive bobbing, they provided greater comfort, whereas the F's are more rigid. Overall, all were subpar; however, the Koni's effectively mitigated the bouncing. The issue lies not just with the shocks but also with the spring weightings. I stated this three years ago, and now Mazda has reduced the spring weights on the new 2025 vehicles. It may be more advantageous to obtain a VIN from a 2025 model and acquire all the suspension components from that model to install on your 2023 vehicle. All components are compatible; I would recommend this prior to investing in alternative aftermarket options. Transitioning to an 18" wheel equipped with a Michelin CrossClimate tire will be beneficial; but, it will remain costly. I would recommend procuring 18" forged wheels instead of the inexpensive and heavy cast Mazda variants, as this would decrease unsprung weight on the hub, hence providing significant benefits.

If I had unlimited funds, I would likely do so. At present, I am unable to substantiate the expenses associated with it, regrettably.

Simply acquire an additional vehicle. Achieving satisfactory ride quality with the CX60 is unattainable; I have experienced this myself and have exhausted all options, now liberated from the ordeal.

Is the diesel model exclusively rear-wheel drive? Are the other PHEVs all-wheel drive, namely rear-wheel drive in their base configuration but with front-wheel drive assistance when necessary?

Since I desired a comfortable ride, my upgrade has consistently included 18" wheels with Michelin tires and a pressure of 2.2 bar, which is the manufacturer's recommended specification. It offers superior ride quality compared to the model I evaluated at the dealership prior to purchase. The RWD variant features considerably less unsprung mass in the wheel suspension and is engineered with lower stiffness (lacking a front drivetrain/differential and rear cross stabiliser), enhancing ride quality and establishing it as my preferred option. My personal experience with automobiles has taught me to never accept tires with a sidewall height of less than 60%.

My 2023 Plug-in Hybrid Electric Vehicle is equipped with Koni shocks and H&R springs. The car no longer features a gelatin suspension, preventing rear seat passengers and cargo in the boot from being jostled over speed bumps. However, it is far from pleasant; the intensity of each road bump is significantly greater than that of any other Mazda I have driven. The suspension is rigid, potentially excessive for certain individuals. However, I still prefer it in comparison to Gelly "E" factory shocks. Driving on smooth roads is quite pleasurable. Cornering and braking present no issues whatsoever. I initially had 18-inch wheels with Toyo tires but upgraded to 20-inch wheels with Bridgestone tires solely for aesthetic purposes. Bridgestone tires are much subpar. On 18-inch wheels, the Koni's provide a significantly superior ride compared to 20-inch wheels with the aforementioned tires—resulting in a quieter and more comfortable experience. I have now updated to 20" front wheels equipped with Pirelli Scorpion Zero all-season tires, and I immediately notice the difference. More subdued, gentler, and superior. Your options are limited in this situation. Aftermarket items are exclusively Koni for shock absorbers and Eibach alongside H&R for springs. That is all. Some Japanese items exist; however, they do not officially support PHEVs. It was not a year ago. Additionally, there is an air suspension option available for a substantial cost, which can effectively resolve the suspension problem. HERE An alternative is the Mazda springs and shocks from the 2025 model. Mazda asserts that they are incompatible, however that is erroneous. Conduct a test drive of the 2025 PHEV; if it meets your approval, record its VIN (preferably a newer model) and proceed to the dealership to purchase the whole set of the latest shocks and springs. You will receive the same ride as the 2025 model.

Another subject is the enhancement of ride quality. I utilised the search function but preferred to finalise it within a single thread here. I possess a 2023 CX60 PHEV Homura version. I have already received the shock replacement from my Mazda dealer, or so they assert. My objective is to enhance ride quality: improved suspension, increased ride comfort, and superior handling. To accomplish this: suspension enhancement plus wheel and tyre enhancement. Suspension: I have reviewed the Koni shocks and dampers (both front and rear) and observed a range of opinions. I am enquiring about alternative choices that can be customised to my preferences, rather than the non-adjustable prebuilt Koni shocks. Are additional springs necessary or unnecessary? I intend to replace my original equipment manufacturer 20-inch wheels with Toyo tires with 18-inch wheels using a more comfortable tire. Has anyone experienced the transition to a lower wheel size and its impact on ride quality? Any other suggestions would be greatly valued! Thank you
