If the turbo pressure isn't reaching the expected level and only reaches 0.8 in the 5th gear, how can you effectively check for leaks?

The air conditioning isn't cooling. I checked the pipes and found no leaks. However, after adding refrigerant, it was gone in less than two months. For an 11-year-old imported Mazda CX-7, what usually causes this issue?

I have a 2021 2.0F1A manual Euro Victory, and when I shift from 2nd to 3rd to 4th gear and accelerate, there's a clicking sound between 1100 and 1400 RPM, like it's low on oil. Does anyone else experience this? Once the RPM reaches around 1500 and the turbo kicks in, the sound starts to decrease. The 4S shop upgraded the ECU, but the sound is still there, whether the AC is on or off.

Why can't the Pajero burn out when the brake is fully pressed and the accelerator is fully pressed in D gear, with the RPM only reaching a bit over 2000?

My Scirocco feels jerky when shifting in S mode. At half throttle, it reaches 4000 RPM and reports an engine fault that needs repair. The EPC light is on, and it mentions something about oil pressure and the engine's maximum speed at 4000 RPM. What's going on, experts? Once I restart the car, everything seems fine (after the car is warmed up, with both water and oil temperatures up to normal levels).

To reset the tire pressure light on the MG GS 4WD, follow these steps: 1. **Check Tire Pressure**: Ensure all tires are inflated to the recommended pressure levels. You can usually find the recommended pressure on a sticker inside the driver's door or in the owner's manual. 2. **Drive the Car**: Sometimes, simply driving the car for a few miles can reset the tire pressure monitoring system (TPMS) if the tires are properly inflated. 3. **TPMS Reset Button**: Some models may have a TPMS reset button. Check your vehicle's manual for its location and instructions on how to use it. 4. **Professional Assistance**: If the light remains on, it might be necessary to have the system checked by a professional, as there could be an issue with the TPMS sensors. Please follow these instructions based on your specific vehicle model and refer to your owner's manual for more detailed guidance.

Is it necessary to fix the issue if the oil level drops to the lower limit on the dipstick after 5,000 kilometers? Why is there oil leaking from the pipe and turbo area at the back? Has anyone else experienced this problem? The mechanic suggests replacing the oil separator. The car has 60,000 kilometers.

I recently got a 2013 1.4T VW Touran with 110,000 km on it. It's been owned by one person before me. Currently, the big electric fan isn't working, but the small one still is, and the water temperature isn't high. I'm planning to replace it in a few days. The only issue right now is a whistling noise in 5th gear at 70-80 km/h. It doesn't happen in 4th gear, only in 5th when I accelerate, and it stops when I release the gas. 🙂‍?️ Seeking advice from experts—is this a transmission problem?

Only the driver's side keyless entry is working, and I've checked the settings, everything seems fine. The auto start-stop isn't activating anymore either, though I don't really use it. Has anyone else encountered the same issues?

Does your 1.6 naturally aspirated engine consume oil too? Mine has only run about 90,000 kilometers, and after the last maintenance, I drove less than 2,000 kilometers before the oil light came on. When I checked the oil dipstick, it couldn't even reach the oil level.

Why has there been frequent gear lag recently? It's a 2019 model with a 1.4T dry dual-clutch. After picking up speed and then braking, the gear doesn't match the speed. For instance, it's in 6th gear at 45 km/h and 5th gear at 35 km/h, but it doesn't downshift further. It upshifts quite eagerly. Went to the 4S shop, and they said the engine isn't strong enough, and the gearbox can't be adjusted?
