You may have knocked the tracking out, which could give a heavy feel to the steering. Get that checked.
Best way forward then is a VCDS scan and see if any faults are shown .
Is there a chance of knocking the tracking out even if the impact was just with the undercarriage of the vehicle? As I'm pretty certain the wheels never touched the deer. Also you will have to bare with me as I am not the most mechanically minded person! Also 2 days after the incident, my car alarm started to sound for no reason which it has never done before. Could this just be a coincidence? I have been turning off the internal sensor before locking, and to my knowledge the alarm has stopped going off. Could this also be related to the impact?
We all had to learn at some time - so don't worry! That's what the forum is for
No idea about the alarm, but you could have knocked a sensor or wire loose.
If it were me, I would get it to a garage, good indy or main dealer, explain the circumstances and symptoms and get it checked ASAP.
Where abouts are you? There is normally someone on here who can recommend a good VW place in your area.
