Is it normal for the turbo of a 2008 Touran 1.8T to cost over six thousand to replace?

Is it normal for my 2008 Touran manual 2.0 to run at 3500 RPM at 120 km/h and 4000 RPM at 140 km/h on the highway?

Hey guys, for the 2018 2.0L model used for commuting, is it normal if it costs a bit over 1 RMB per kilometer?

The 2008 Volkswagen Touran 1.8T shows a fuel consumption of 11 liters on the highway. After changing the fuel injectors and spark plugs, there's still no improvement. What could be the reason?

Is the clutch very heavy? Do I need to replace the clutch kit, or should I replace something else? Or is this normal? It's a 2014 model with over 200,000 kilometers, and I just got it as a used car.

My car was registered in 2018 and has just over 10,000 kilometers. It's been in the repair shop for half a month now. They said it's the electronic rocker arm that's broken. First, they tried replacing the spark plugs, but that didn't work. The ignition coil didn't work, and neither did the injectors. Then they said it's the electronic rocker arm. Wow, it costs 12,000. Sigh, they suggested I replace the engine, which is around 15,000. I don't even know what to do. This car isn't worth 50,000 now, and fixing it costs over 10,000.

I need some advice from experts: I have a 2013 1.4T Touran. Recently, the engine occasionally makes a loud noise after starting, and the idle speed is over 1100. But after turning off and restarting, the engine sounds normal, and the idle speed is around 700, back to normal. What could be the issue?

Is it normal for a 2014 Peugeot 2008 1.6 automatic to have the engine temperature rise very slowly, taking over ten minutes to reach 70 degrees? Could it be that the engine oil is too thick?

My car is a 2013-2015 model Jetta with a 1.6-liter engine. Sometimes when starting the car, the engine revs low, leading to failure to start properly. Normally, when a car starts, the engine speed should be over a thousand RPM before settling down to idle speed. However, sometimes my car starts at 800 RPM, feeling like it's about to stall. The battery is newly replaced, and tests show no issues with it.

My car is just over 3 years old and has only 36,000 kilometers on it. The electric tailgate is acting up right after the warranty expired for a month. So frustrating! I asked about it, and they said it would cost over 2,000 to replace. Plus, at the 4S shop, they just told me it's out of warranty...

Hey guys, the AC isn't cooling and is blowing hot air. When I turn on the AC, the compressor doesn't work, even though it's new. The repair shop said the fuse box has a bad connection and replacing it would cost over a thousand. What should I do?
