Lumpy insignia after traction light

[pauluk49]

Hi guys. N gals. Took motor for a spin. All ok. Heard a hissing noise. Traction light came on. Well the car skidding on dash. The car went to crap. I pulled over. No flat tyres and nothing has exploded. No visible leaks. I managed to get home but no idea what happened. It did the same thing on way home and I felt the drivers seat vibrate. Any ideas?

have you plugged in a code reader?

Hissing could be turbo hose split, leaky boom boom down.....
traction control light could be a fault abs sensor, common on these to go

Codes coming up are p0354 p0171 and p0304 . It's a 1.8 09 plate insignia
