Improperly gaped plug you cant just put them in from the box they need to be gapped for proper function
also your spark sleeve might have slipped down from factory install theres a tool the dealers use to bring out sleeve for sparky

Im looking for a tyre pressure sensor for my renault laguna 2033 plate but not sure what im looking for or how to fit one thank you


1. The tyre has to be removed to fit the tyre valve/ sensor unit to the wheel. . Tyre dealers will do this for you when you supply the sensor.

2. Any renault dealer parts department can sell you a new sensor.

3. The new sensor has to be programmed to the car's tyre pressure monitoring system (TPMS).

3. Here is a list of information about the Renault Laguna tyre pressure sensors to assist you. The 2nd link below shows a picture of the tyre valve/sensor unit that fits to your wheel.

Can I replace turbo on a Renault Laguna 1.9cdi with out removing cylinder head


Access is stupid on these. If you don\'t want to disturb the head then drop the whole front subframe and engine and do it on the floor. If its done more than 80-100 k miles then change the head gasket anyway. They are usually corroded internally by then. Flush and fit new antifreeze at the correct mix.

Why is my renault laguna ii losing power and will not rev above 4000 ?


had similar issue but with laguna 2.0 IDE where there are 2 sensors at the end of the fuel rail left hand side of engine looking into engine bay from front of car, they both look like cylinders about 2 inches high with terminal points for wires on top, replacing the sensors resolved the issue but they were really expensive and only available from renault, i was able to run the car as long as i stayed below 4000 revs if i removed the lead from the top of one of the sensors. be aware if you do change the sensors yourself, do it a while after you have last used the car and engine is cool, as removal of sensor causes the pressurized fuel to come out at speed all over you. hope it helps

Renault laguna 1998 petrol fuel line


Before going into the fuel lines check for spark at the spark plugs. When there is no spark, the injectors won't squirt fuel into the cylinders but there will be pressure at the injector rail and the pump will work.

Renault laguna problems


Run fault codes as the light may also refer to the engine having a fault.. When the CPU finds a sensor that is outside set parameters it will put on a light to let you know that something is wrong. With Renault it may be the service light meaning check the engine and not service the engine.
