Hi, I recently brought a Vauxhall Adam in December last year, I took it to be serviced and it ended up needing a whole new cooling system which I had fitted for about £550. A couple weeks later my engine light has come on. The fan seems to not be working again in the bonnet and when we use the code reader it says P0171, which is a lot of things. I’ve just got in my car to drive it and as I pulled off it made a loud pop noise, it felt like it was under me. Not sure if anyone can help?
