I've searched and searched and cannot locate anything relating to this particular problem. I've taken good advice from this forum in the past (replacement TDC sensor, coil pencil, coil pack and the seat sensor bypass) . . so I'm hoping that someone can help out this time. :eek:
Started the Clio (1.2 16valve 2002) and all was fine, however after approximately 5 minutes the engine stopped and the second STOP light was illuminated - (the one surrounded by the engine icon). The immobiliser LED isn't going mental so it can't be that. I've disconnected all the plugs and leads along with the coil pack, cleaned and refitted but no joy.
:steam:
The last issue I had with this piece of junk was the ECU loom was bitten through by the stupid metal surround. But refitting that after putting padding around and re-securing has cured that.
:crazy:
I've spoken to a local independent Renault specialist and he's said it's most probably an electrical fault and the majority of them won't come up on the diag's test, in fact apparently more often than not Clio's won't even talk to the diag machine. He mentioned it could take many hours to locate the source of the problem in such a case.
:steam:
I'm stuck at present, not sure what to try next. There's no spark to the plug's so I figured my recently changed coil pack maybe at fault. I'm going to check that tomorrow with a meter as per the Haynes manual. Failing that, anyone know a good local Renault specialist that's mobile that lives in the midlands who's not too expensive ?:confused:
Having moved into a new house this week that's equally throwing up problems I'm at a point where I'm considering torching both the house and the car.

Thanks for the response, I was informed that if it was the immobiliser the red LED would flash erratically constantly on being set, however the LED is flashing as normal. I'll have a mooch through the FAQ section to see what I can find.

Wow ! Clio's REALLY are *pants*
Luckily it wasn't the timing belt, well not this time.

Like all brands of cars some have problems from time to time. Being a single brand forum always gives the impression of major problems but look at any car forum and it is the same. The main thing is that the members on this forum try to help each other and we have a good time with it

Well the car is still as usefull as a bucket with no bottom. Looks like it's possibly either a faulty ECU or a fault in the loom that feeds the ECU which I hear from other forums, action groups and the DTI is installed too tightly causing various electrical gremlins. Looks like it's not going to be a cheap fix and any fixes won't be a guaranteed resolution.

I thought this site was particularly interesting:
2002 Renault Clio Extreme Comments - Carsurvey.org

Oh ! Even the BBC Watchdog have an issue listed but it's a nice and simple mechanical fault:
BBC - Consumer - TV and radio - Renault statement

Consumer Action Group have a little thread too:

Loom & ECU

After a few day's prodding and calling a few auto electricians and Renault specialist's it looks like it's possibly a new wiring loom and ECU re-map required. Issues point to a dodgy connection on the connector to the ECU on the loom but apparently you can't purchase these separately, (would probably cost a few pence) - and instead a complete new loom is required. I've been quoted £360 + VAT for the loom and anywhere from £400 + VAT to £700 + VAT for the ECU. However there appear to be some companies around that exchange them.


I can't wait to ditch this car, I'd give my left testicle for a Japanese, German or even - (heaven forbid) an Italian one instead of this useless French piece of junk. :steam:

Hi,

I'm new to the forum, I'm having the same sort of problem.
It's a Clio RT 1.6 16V 2001, brazilian version.

It begins with starting difficulties (needed to step on the pedal) and sometimes irregular idle. Not always, but only when the car rested a day or so. After the start, lots of unburnt fuel, sign of very rich or lack of some sparks. Seconds passed, perfect idle, power, acceleration. Left on the garage, 2 injectors changed, as the mechanic said they had uneven fuel flux. Ok, for some days, but it happened again twice.

It has 115,000km, the TDC was changed with 35,000km: starting problem. Camshaft belt changed with 80,000km as per manual.

Now, since sunday, it won't to start anymore :-( , the day before it worked uneventfully. So everything was ok, fuel ok, power ok, coils ok, ECU ok.

Symptons:
- Fuel pump ok.
- Flooding, so injectors ok, apparently no sparks;
- TDC sensor checked, 225 ohms;
- Idle control valve changed, it was very hard to move;
- Immobilizer ok, led goes off when key turned;
- Sparks checked once, was ok, checked again day after, no sign of spark.
- Not even a single cylinder is firing

So, could be an intermitent TDC sensor failure ?

Don't know what to check more. The ECU is recognizing the TDC sensor: no warn lights, injectors is being open.

I will try to change the TDC sensor today.

Regards

Bad luck, won't work. No sparks, any coil. Fuel being injected, fuel pump turned off to prevent flooding, at least the pressure regulator is good, with no pump some residual pressure.

Left to check the wiring to the ECU.

Beggining to blame the electrical enginneers of this car :steam:

Regards.

Now it's working.

I was trying to check the sparks with only one coil conected, it's the wrong way, the ECU cuts all coils. It must detect all coils in order to fire.

Need to spent £14 in a local garage to make a scanner check on the engine, all ok now.

So far the suspect is the usual: TDC sensor, that is new now. But I will keep an eye on the coils, the first symptons point to them. Probably 2 of them do not fire sometimes.


Regards
