Suspect wheel speed sensor. Likely the shudder is traction control activating from false reading of wheel sensor.
Have ODB codes read, it may identify which wheel.

You need to have your brakes inspected by a professional. The lights indicate that ABS and traction control are not working...although brakes will work without these features, a humming noise can indicate more problems to come.

look on the brake pedal assembly and their is some sensors that run off the throttle and brake and clutch,could be these are playing.But it is a renault with encrypted software so evan if you can get fault codes read they dont always show the right fault codes ,this is deliberate ploy to create work for the dealers.Trust me on this one

These type of engines have direct rail injection so each cylinder has an injector. The problem sounds like the engine is only running on 3 cylinders (or less). It could be a faulty injector. Are you losing coolant? Is it overheating? Is there steam or excessive smoke coming out of the exhaust tail pipe?

im willing to bet that you had a coil pack fail on you. they are one of the most common failures on the 1.8t engine. another thing i would check is for any boost hoses that may have popped off if you were accelerating quickly.
but before you go and buy a new coil pack. unplug your maf sensor and see if it runs any better than before. if the problem goes away when you unplug you maf then the mass air flow sensor is bad. but if its the same then you have a bad coil pack.

Sounds like you're not running on all 4 cylinders all the time. Could be one or more dirty spark plugs, bad ignition coils, etc. You'll ruin the engine when you don't get it fixed quickly, even after repairing you might notice a significant hp-decrease.
My advice would be to take it to the dealer asap and have them troubleshoot. Since they can read the faultcodes from the car's ECU, it should give a good pointer to the cause.
