I'd be looking at the computer module.

You Didn't say whether you replaced the battery in the remote,but I would try that first

gas or diesel..

ignition bad or auto shutoff relay fused on..

hi what was the code (p 0244)sounds like you need to replace the the turbo wastegate valve .sounds to me like its overboosting as if the charge from the turbo gets too hot the engine will misfire thus causing damage to engine ,the waste gate valve is there to prevent over pressurisation

Hi. Best guess is the door loom. Open the door and there is a rubber grommet between the body and the door where all the wires run. The wiring can break inside the rubber grommet so you have to unclip it from one end and gently pull it back to reveal as much of the loom as you can. If it looks ok gently pull each one in turn and see if any come loose. Jon.

very common fail search for a place that does dash repairs it is due to cracking of the solder joints ok when cold then fail when hot.

check your oil level ,if ok change the sensor .or do an engine flush then drain and refill and change the oil filter.

When you cycle the ignition to the key on, engine off setting, do you hear a relay cycle for about 3-4 seconds? If so, that should indicate the ECM is firing the fuel pump relay. Most vehicles have a port on the fuel rail for testing fuel pressure. See if fuel is present here by pushing in on the pin in the port test valve. Have you tried disconnecting the negative terminal from the battery for a half an hour to reset the ECM? Does it have spark? I am surprised that a car company that prides itself on safety, does not have a rollover switch.

sounds like it might be the fuel regulator

Hi theres a switch on the brake pedal & a solenoid on the gear shift to stop you moving whilst the car is put into drive if the switch is not working correctly it won't release the solinoid to release the gear shift or the soinoid is faulty or your not pressing the brake down hard enough hope this helps
