I had a free trial map put on my car yesterday so was giving it quite a bit of grief last night, today i noticed a knocking noise from under the car in the middle towards the front (which i could slightly feel from under the pedals), it's when i go over larger bumps and speed bumps at 15 - 20mph + . At first i thought it was bushes at the front but driving up and down my drive i have noticed it knocks on what ever side i go over the bumps on.. then i thought it could be the exhaust so got under the car and gave it a good shake, but still nothing.
Has anyone got any ideas of where i should look next ?
Also, nearly forgot to add, my clutch slipped slightly this morning. Took it to a friends garage and he told me to put it in third with the handbrake on and see if i could pull off, which i could (with a lot of smoke). i dont know if thats the right thing to do but, now my clutch pedal has got alot lighter, still seems to work ok though.
What could this be?
Its a amk s3 by the way.
