Toyota recall to replace EGR cooler - since done no signal on radio

Hi I drive a 171 D Toyota Versa - Diesel - I got a letter from Toyota 28/10/22 that car recalled to replace EGR cooler and I should take to local toyota dealer. So I took it to Denis O'Mahony off the m50 in November. Since the work was done to replace EGR cooler - I have no signal on the radio, the economy mode no longer comes on at traffic lights when car stopped and engine running. And the beep sound that I crossing a white line when driving - seems to only work sometimes. These were 100% all working before EGR cooler replaced. The car has just 70km millage and is like new. I took car back to Denis O'Mahony mid December - they said replacing EGR cooler could not cause issues I'm having ... They not going to help me resolve issues unless I pay myself...

What should I do ? Or any person have similar experience and how resolved ? Thanks..

I did and took back to Toyota garage today. They again saying my issues not related to recall and asking to. put in a new battery (180 euro) to solve eco issue and replace the whole headset on the radio cost 800 euro. So I need. to pay. at least 980 to get my car back to condition I sent it into the garage for the recall. The customer service guy said I could not prove the car did not have these issues when taken in for recall. But I'm 100% certain I did not have these issues. Do I pay the money to fix issues or. what can I do ? I phoned/emailed Toyota Ireland but getting no response.

my car is still in Denis Mahony & I just phoned to see if they tried a new battery and if this resolved issues. They said they tried this it resolved economy issue but not resolve radio issue. On goodwill - garage said they give me radio head unit at cost but still probably be 850 + 200 for a new battery. I will need to pay this amount to get my car back to the state it was when I dropped it into garage for recall repair.
