Hello everyone, i have a 2015 skoda citigo, 5door, 75hp, love my little car, done some slight modifications to it, exhaust, HR springs, pops and bangs software. I was driving my car regullary, came to a stop, turned off the car and when i turned the engine back on, two errors appeared : check engine and EPC (electronic power control). I took my car to a service, pluged in vag com, found out the error was appearing because i had a problem with the throttle body. Got the throttle body out at the service and found out that the return spring was broken, split in half, and this would stop the throttle from closing all the way. Has anyone encountered this problem before? Why did this happen, can the software mods cause this (what the tuner modified is how much gas is thrown in the engine, nothing to do with the throttle, and the tune was done by profesionals and with the thought of keeping the engine safe). Is there any way of just replacing that spring? And what can the cause be?
