MAP sensor replacement. Throttle valve question

I have a charge plausibility code. Cold start. ISTA says check “connectors, and “plugs”. And replace pressure sensor.

So I have the pressure sensor out. And waiting for the new one. How difficult is it to remove the throttle valves and replace gaskets that go to the block. Do all 4 throttles pull off together?

Here’s a video with my fan , and belt removed.




I guess no one has attempted the throttle valve gaskets. I’m going to do this, and I’ll make a DIY. The idle control , and both actuators need to be removed. And the wiring harness needs to come up fully.



I’ll report back with pictures and help on DIY

The throttle gaskets are rubber profile seals, given their design and material they're not known to start leaking. But if you want to replace them, no big deal its not a hard job, but it's not likely going to fix your fault. You don't need to remove the actuators and you don't need to fully remove the wiring harness.
