    Hi Paul thanks for this vid. Do you think doing this will help my 2004 cc roof? I keep getting a fault message and beeping non stop which is a nightmare! I tried putting the roof down and driving for a while but still keeps beeping and showing a fault :-(

    Also clean out the water runs each side of the bulkhead ,the modus has a flap each side its crap just cut the flap off the water can then run out instead of pouring over the fuse/relay box , Renaults are a marmite car a course in gynecology helps as they cram everything in , there are PDF,s out there for free I got one on the AL4 transmission that explains a lot !

    Can you suggest anything for my Megane? It went through a deep puddle quite fast, the electricals went like they were possessed. Sprayed with wd40 and all seemed fine. Now, the battery goes flat after 4+ hours. We have a new battery and taken it to garage who are none the wiser, other than changing the Ecu. Any thoughts? Thank you.

    Hello. I have a 55 plate Clio, similar thing driving down the road and power assisted steering dash light came on, then the seatbelt dash light, followed by the locking system going mental, engine still running, switched the engine on and off and it worked fine and got me home. Will this video be of any help to me?

    Hi Paul! My 2001 rxe 16 vaive hatchback takes 20 to 40 start attempts over about one hour before it finally starts as if nothing was wrong, varoom very smooth once it starts. After a long trip inland it will start every day for a week or so – I live near the sea, do you think it could be the salty air? That is, could it be the same electronic fault? i think the fuse box is in a different place though… Many thanks for your video and help!! I look forward to your reply all the way from South Africa. As we say here I am gatvol of this car!

    Water got into the looms in the passenger side of my renault megane convertible cabriolet. I dried all these off and there was some corrosion and a few of the wires seem to be disconnected! Is there any wiring diagram I can look at so I have an idea where the wires connect in the loom again?

    I have a Renault Laguna that's displaying ABS and brake light warning signal, the speedo isn't working but the car still drives! When I insert the key card the car shrugs before starting and does the same when I switch off the ignition. Will this fix the problem, it seems like a electrical connection fault….

    Hubby is a mechanic, he has hooked it up to his scan tool, changed injectors over replaced injectors replaced coils, etc etc, had different auto sparkies look at it and no one can find what the problem is ?

    My Renault says check injectors and check gearbox and goes into limp mode when driving. Any fixes?

    Hi Paul

    I was in dire straights as I received the "Steering Locked", Steering not locked message today, I drive a Renault Megane Dynamic 2 and was fearing the worst. The last time I had this problem I had to fork our thousands. After watching your video i decided to give it a go, and without even needing to take my unit out, i basically just unplugged and plugged back in a few of the plugs on my fuse-box and magically the error disappeared and my car started again! Thank you so much for sharing this with us. Renault driver all over the world gets screwed on service and price daily and I thank you for being the difference.

    All Reno's need a hole drilled into the lowest point of the fuse boxes , after you have cleaned them up and they are working OK then you go to tool station and buy a can of spray wax and spray anything electrical from connectors to fuses !

    Every Renault should come with a chrome badge on the back that has just two letters CE that stands for CRAP ELECTRICS !
