Fuel filter light flashing megane oasis?? - 2000 Renault 181

Inside the fuel tank.

run fault codes and look for MAP/MAF and accelerator position sensor problems.

Most probable cause is a poor earth on rear light cluster should be simply enough just clean all connections and put small smear of lube on connections before tightening

Pray which fuel filter are you refering too here as no information regarding the origens as to weither this vehicle is a diesel or a petrol also the year as the filter have been changed in regards to location and type

Check your fuel filter and add some rubbing alcohol or heet to the gas tank. You more than likely have water in the fuel.

It could be your onboard computer or locking module, as the guy next door had an identical problem on his Megane. A tech came and changed a module then programmed the 'brains'.

it`s the oxygen sensor
thats why the car is mix fuel/air in wrong ratio generating unburned fuel in form of black smoke and check lights on
you got to change that sensor
i hope my answer was helpful and convince sir .

Forget the injectors. They worked before the new pump,why go there.
The new pump maybe defective,it happens, I suppose.
Your only problem, may have just been the fuel pressure regulator ,and not the pump at all.
I hope you mean, you changed the replaceable fuel filter, not just the sock on the fuel pump in the tank. If the filter is really dirty, it would stop the flow of fuel, and give you less than 40 to 70# psi,but 18#.

I have 2 meganes im working on at the moment both have the same problem. the electrical falt light is on coz the pipe has snapped (or come off) under the bonnet on the passangers side close to the window (theres a black box about 2 inch wide the pipe connects underneath). if I reconect the pipe and grab the engien with both hands it wobbles and the pipe pulls off. I suspect this is coz one (or all) the engien mountings are shagged. and this will be the cause of the juddering when driveing in first and second gears. solutions iv have come across for juddering involve changeing the coil pack but thats nothing to do with the problem my 2 cars have as one of them has new coils. they are 1.6 petrol, p reg and s reg

Firstly you need to know the make of the towbar, then you can download the fitting instructions from the towbar manufacturers website. As far as electrics are concerned, I would recommend NOT using the secondhand electrics that you have unless you have a dedicated plug-in wiring kit as the wires were probably cut and may now be too short to use and the sockets may not be in tiptop condition, It's well worth the small expense af replacing them. The actual wiring will depend on what year and model the car is.
