Re: Renault Clio 2 - Loose Wiring Loom Cover Cutting Into ECU Loom*FIXED*

I have a renaut clio, billabong, which seem to have the same problems to do with losing power and juddering, which is dangerous now on the motorways.

I had a look for the black box on the back of the engine and can see that the cover, tamper plate has been removed and the wires are exposed, I am not sure if they are damage or not as I am not a mechanic.

should the wires be completley covered and how can I tell if they are damaged?

thanks

Unhappy Re: Renault Clio 2 - Loose Wiring Loom Cover Cutting Into ECU Loom*FIXED*

Hi guys, My clio has just encountered this problem also. I have removed the top half of the back box and wrapped up the wires tightly with insulating tape. When I turned the engine on the light went out, so I took it for a test run, no sooner had I got it up into 2nd did the fault happen again.

Turned the engine off, REALLY low revs in idle, but give it a few minutes it seems to be able to drive at around 40 fairly fine, but light stays on. ANY help is much appreciated!!??

Thanks, Leon

Re: Renault Clio 2 - Loose Wiring Loom Cover Cutting Into ECU Loom*FIXED*

I'm having issues with mine, perhaps it could be the same thing?...i've posted this elsewhere but i think it may be worth me looking for help here.

I've looked for the little black box housing the ecu cables etc but my clio hasnt got a box - as far as i can see from the pictures posted anyway. Mine looks nothing like these photos.

Ive a CLIO MK 2, 2005 *MARCH* and my problem is my electrical warning/ coil light comes on when driving and the power goes. This has almost killed me when I was on the motorway. When I pull over, stop and start it again goes okay for a little while. It has come on once or twice in the past few months but was especially bad in this recent rain and now is coming on all the time (but yes, it is still wet weather). I'm guessing its putting me in "get you there safe" mode as it wont rev over 3000. The AA came out with diagnostics and couldnt find anything. Previously i had a local garage look at it and have the print out saying:

DF125 PEDAL POTENTIOMETER FAULT TRACK 1 : 2.DEF
DF126 PEDAL POTENTIOMETER FAULT TRACK 2: CO.0
DF344 INJECTION <-> INSTRUMENT PANEL LINK 1.DEF

but they have said these wouldnt be the cause...

Anyone have any good insight?

Engine wiring loom issue? (how would i check when mine doesnt have a little black box?)
Would it be the sensor to the accelerator?
The accelerator body?
How about the EGR valve?
Fuel filter? (its had a recent service)
Battery issue?

Your hivemind insight is greatly appreciated as are re-direction/links.

Re: Renault Clio 2 - Loose Wiring Loom Cover Cutting Into ECU Loom*FIXED*

Great posts guys....hope I will find the solution to my problems here.

I've got a 52 plate Lag II 1.6 which has misbehaved with the limp-home gremlin more or less from the time I brought it in 2006. Unfortunately as it is in St Lucia we lack Renault dealers or any local experties in fragile french electronics. I've done the usually throttle body & TDC changes as well as removing cleaning and re-seating several sensors including the actuall ECU . These changes appeared to buy me a little more time but then the problem always returned but with incressing frequency. Short of starting up the engine once a month or so, the car has been stationary, unused, unsellable since 2008. I was on the verge of consdering a ECU /key swap but then thought, as the problem is getting progresively worse it might be related to a corroded/damaged ECU loom?
Are there any obvious places to look for this sort of damage. Does the Laguna II have a simillar loom cover/black box to the Clio?

Thanks
