I have had my Polo for about a month it is not registered yet. I have just fixed my DPF issues and it has gearbox faults which I will paste in below. It has sat in a shed for over 3 years after the previous owner got sick of the problems with it and trying to deal with VW.
I was told by the previous owner it had the mechatronics unit replaced and around a thousand k's later it started to intermittently fault and not select 1st gear. Not long after that it went into limp home mode because of being driven for to long with a faulty exhaust temp sensor and a faulty DPF pressure sensor. That's when they parked it. It is a 2010 diesel 7 speed comfortline.
Does anyone have any knowledge of the fault codes below?
