limp mode - 2001 laguna 1.6

[stubydooo]

Hi all,

i have just bought a laguna and it is stuck in limp mode. the light on the dash says it is an electrical fault - when i opened the bonnet i can see the car has had a new throttle body (so i dont think this is the cause) from reading the forums i have cleaned the ecu and this has not worked either.

any help would be good as im not having much luck with cars at the min.

thanks

	ECU Electronic Control Unit In automotive electronics, an electronic control unit (ECU) is an embedded system that controls one or more of the electrical subsystems in a vehicle. Some modern cars have up to 70 ECUs.

	Throttle Body Throttle Body In a fuel injection engine, the throttle body is the part of the air intake system that controls the amount of air flowing into the engine, in response to driver input. While the accelerator is often called a "gas pedal", it would be more accurate to describe it as an "air pedal". The throttle body is usually located between the air filter box and the intake manifold, and usually attached to, or near, the mass airflow sensor. The largest piece inside the throttle body is the throttle plate, which is a butterfly valve that regulates the airflow.

im guessing no one can help me then

Did you buy the car knowing it was stuck in limp mode or has the problem only arisen since?

i bought it at auction so i did not know what was wrong with it.

That's the risk you take when buying at an auction - maybe someone else was just selling their problems on.
On some models the throttle body needs to be reprogrammed to the ECU otherwise it just operate sin default mode. I may be wrong but I would suggest you have the fault codes read to see what comes up.
