2 warning lights on

[col81]

Hi, I have 2 lights on my dashboard it's a 2.0 tdi 140 manual highline plus. I have had for a few days just the orange squigly lane on with a message saying take to a garage and now the normal orange management light has come on so I have 2 on. The car is running fine but it does sound a bit louder than it did. I am ver concerned it has done 88k the car. I have little money so I am understandably worried. Any advice on possible cause? Appreciated. Colin
