If immobilizer light is not constant red when the key is turned to pos. one -> UCH fucked. If immo light stays constant red when turning the key, then start by replacing the TDC sensor a.k.a. crankshaft position sensor.

Just to let you know that the video does not work. You have probably set it as PRIVATE on youtube.

Those symptoms match perfectly to an INNER CV joint lubrication failure. Inner CV joint is senseless to maximum steering lock. Steering lock knock is used to diagnose outer CV joint, it does not work for the inner CV joint. You can probably avoid replacing the drive shaft by just re-lubricating...

After doing some more reading on this topic, it appears that other possible causes are the key fob failing (probably not as you are getting the constant red immo light), UCH failing (high probability in your case), a broken wire anywhere in-between the UCH and ECU as I stated above (moderate...

Constant red immobilizer light after turning the key means that the ECU and UCH datalink is not establishing a connection, although it's trying. The ECU does not have the permission to fire the engine. The ECU stops the engine from cranking whenever the immobilizer circuit in the ECU has reached...

Something like an intake air temperature sensor requires practically no current at all. Current is what makes the wire heat up. Thicker wires can handle more current without heating up. So in your application, the smallest wire you can find will be sufficient. But if you want some concrete...

Could be an UCH related problem. I also had random wiper movements when my UCH unit was failing. I grabbed the 40-wire connector, going into the UCH, and when pushing the connector by hand to a certain direction the front wipers would swipe across the windscreen continuously. But could as well...
