Fuse marked 5fc is the correct fuse for reversing lights and is a 10amp fuse.This fuse gets it's voltage via a brown 12 terminal connector on the engine bay fuse box marked pph2 brown connector. Terminal 9 on this connector is the reversing light output. Hth Regards Mickeybo

The instant you start your megane whether it be hot or cold your turbo spools up immediately which means the turbo actuator arm retracts fully. Vacuum reading should be approx. 26/27 inhg. These Renaults are very prone to maf sensors faults. Two of the most common limp mode faults on these Renaults ...

I would bet my bottom dollar your problem stems from the fuel pipe connectors a very common fault across a lot of vehicles to day a lot of times if a after market filter is fitted their stubs are a slightly smaller diameter causing the connector small o rings not to seal properly. Theres a transfer ...

The df114 fault code solenoid valve (circuit) which implies you have a circuit fault. This would need to be checked out wiring from this valve to the corresponding ecu pin nos Hth Regards Mickeybo

Hyd clutches should be feather light at any time If theres any tightness this is most likely a faulty clutch cover awell known fault across a lot of vehicles. I would advise you to get a replacement clutch sooner rather than later. The pedal box which holds your brake & clutch wont be able to ta...

I would certainly say these codes are red herring cheap e-bay code readers on these are a no no. Maybe if you posted up the problems your having you might get better answers to whatever problems your encountering Regards Mickey bo

The throttle position sensor or it's wiring would need to be checked out on this vehicle. Regards Mickeybo

103 miles on the clock the life span of piezo injectors is approx. 95000 miles. A injector leak back test would be my first port of call. The black smoke you refer to can be caused by injectors dribbling/leaking you would need to get the injector spray pattern checked. Another very common fault on t...

I would be very much inclined to suspect you have a faulty fuel pump. Would need the fuel pressure checked should be 3.5 bar & the pump amps draw needs to be checked Hth Regards Mickeybo

The idle air control valve on your megane. ( Went out with the bow & arrow) was replaced by the throttle position sensor which is incorporated into the throttle body control unit.also known as a stepper motor which controls the the throttle valve that controls the idle air. Can you post up your ...

Egr valves on Renaults learn to adapt themselves after a few runs Regards Mickeybo

The de-phaser pulley should have the inlet cam locked in the full retarded position at idle. These do not activate until approx1500 rpm As their soley controlled by the ecu. If I were checking this I would disconnect the 2 pin connector & put a noid light on it. The problem your encountering is ...

The data iv'e got on the megane 1,9 dci engine code f9q 800 (b8) 120 bhp 03-05 my fitted with allied signal turbo which clearly states the maximum turbo pressure on this vehicle is 0.6 bar. map sensor 2.5 bar ??? How & what checks were done to achieve these results maybe you can enlighten Regard...

Dior you state in your first post you replaced the map sensor & the N75 which is actually also known in the trade as a dump valve so this rules out the the theory that these are not fitted with these 3 port valves. What checks have u done to condemn the map sensor & the N75dump valve. Would ...

Alex you say theres no dump valve because it's diesel. is very incorrect & misleading & it tells me your experience of diesel vehicles is zero these valves are fitted to a large range diesel's Vw's fords Vauxhalls Renaults Peugeot's citreon's diesels all use these valves. Check it out Regard...
