hi everyone having a bit of trouble with my A3 1.4 tfsi 2009

2 days ago I wanna driving down the motor way stupidly going a bit fast then when I got home my engine check light came on the car also idols strange sometimes bouncing up and down

Any one have any idea. Cheers

I doubt it has anything to do with going a bit fast, get the car scanned for fault codes so you know what your looking at
