Volkswagen Beetle - VW Beetle 1.6 (2003) ESP Light on - ladys

Hello, I am proper gutted.

Only had my car 11 months and in the past month the radio has died ( sony one, so not really the cars fault), then it went into the dlrs to have the heated wing mirrors replaced, which took a week!!

Then as driving it home the Exhaust Emissions light came on. Turns out I had a hose which had got a hole in it, so yesterday got the hose and my normal mechanic replaced it ( decided it was more important to have my car than to take it to have it done under warranty).

So this morning went to Tesco, and the ESP light comes on. I am starting to wonder if I have brought a lemon ( although I haven't had any problems for 11 months) Does anyone have any ideas what could cause this? Could the previous oil breather pipe have any reflection on this or have I just been damn unlucky?
