SOURCE: renplate fault scenic 1.9dci 55plate no power revs

you either have a blocked catalytic converter or a faulty air mass meter. on the exhaust pipe, you will find the lamda sensor plugged in just before the cat converter. disconnect the attached wire from the plug end and remove it. start the car up and rev the engine. if it revs freely, you need to replace the cat.

What is a problem my opel corsa lite 1.4 2006 model rev high when im stoping at the roboot or stop sign even if im not moving after i start rev go high to 200 and it drop down and up again


As long as the idle air control valve is working, ( I assume this is what you replaced, I would first check to make sure it is operating correctly), If it is, then Id begin searching for a vacuum leak

Renplate fault scenic 1.9dci 55plate no power revs only to 2500 revs i do have clear particalate filter warning light on


Seems like the common low fuel pressure issue.

There is a hidden low pressure (3 bar) in line pump on Renault DCi's, I think it is on the passenger side flitch on your year.

Is it cold ( around -3 to +6) where you are?? This kills the inline pump because derv gets thick and glooky causing it to sieze up.

When this happens the HP pump is starved and revs limit to 2500.

I have an '86 951. It will not rev above 1600rpm.


clean out the fuel pressure regulator with carb cleaner spray(a good clean ), then spray dry lube into it. This part is located on the fuel rail, sits at the front of it, has three connections/holes and fuel comes out momentarily after disconnection.

Opel astra 1600 16v jerks at low revs when car is hot/warm, fuel filter new air filter new, replaced fuel pressure reg, new plugs, still the same, 3 bar feul rail.


sounds like the iac might be giving problems, check ur idle air control valve on the side of you throttle body if its working right, replace if not.
