2016 Astra Tech Line throttle issue

[chalkie]

Hi there,

I have an 2016 registered Astra Tech, and since the day after I brought it I've been having issues with it going into limp mode, the OBD reads it as P2128 and P2138 throttle voltage error.

 

A garage replaced the throttle and sensor but the issue persists.

 

I've tried everything and I'm at my e end, no garage seems to be able tofix the issue and as I've brought it on finance the Company are saying I have to repair it.

 

Any advice on what it could be?

 

Thanks in advance.
