I have Skoda Octavia 1.2 TSI from 2011.

 

The error actually appeared few moths back and I replaced the throttle body with new one (used original) and prefomed a Thorttle body alignment (TBA).

 

All went well until about 4 months later suddenly the ESP light and EPC icons light up on the dashboard. The car enters a limp mode where you barely can maintain speed. I have been driving the car using a Bluetooth OBD. By clearing the fault I can accelerate again until the fault appears again. It seems that if I hold the pedal still, it behaves good but once I need more power, the error comes back.

So I inspected and cleaned the TB, all seemed OK. I then tried to do TBA again, but the VCDS says "Running" ... and then ... "Aborted-Safety reasons".

Now there is permanent error which cant be erased:

Any ideas please how to fix it?

Just for your information. I was able to to perform TBA. The error could be erased for some time if you do idle RPM adjustment in VCDS. (I think it was Select ->Engine -> Adaption.) ( My Skoda talks UDS protocol). Then you need to exit the engine menu and go back again to starting page, then return (Slelect -> Engine) Make sure there are no fault codes and do the Throttle Valve adaption.

 

Once the P1559 error was gone I started trubleshooting the Throttle body. I taught the error could be somewhere else  since the error occurred with both throttle bodies I had (wiring, corroded ECU plugs etc). In the end it turned out to be faulty DC motor. So I combined the two faulty throttle bodies to make one good one. Next time it fails im gonna just buy new one.

Good result, sometimes it is better to buy new as you never know the status of the replacement part or indeed if it has the same fault!
