2004 Renault Clio

the fault code you are describing does not exist (D0670) There are no D codes .. and all codes starting with a zero ..ie. P 0 are all generic codes which means they are standard across the board to all manufacturers .. only when you get into codes P1/B1/C1 are they manufacturer specific.. but generally P codes are standard .. if your scanner is telling you the fault and there is no actual symptoms on the car (just the light) clear the code, test drive the vehicle, if the code doesn't return job done. a lot of times codes show up because of a slight hiccup in the ECU. Renault have always been very secretive in there releases of information to the general motor trade ??that way they make more money ??

I have just spoke to my buddy at a renault dealer and he confirms your fault code is correct .. this is what i meant about renault being secretive ? lol .. but i still stand by my statement .. if vehicle running fine .. clear code, test drive car and job done .. this is what reanault would do anyway an charge you $$

Hi,

Thanx for the reply. Im glad to here that its not just me being daft and cant find them easily! Iv got to feel sorry for my mate tho, he had that control module changed for a lovely figure over £120ish quid fitted and guess what... the engines still cutting out after a long dual carrige way run. The garage said theyve done what the ECU fault code said, but if he books it in for a rolling road test (And they want payment for that aswell!!) They should be able to find out what the problem is.

The problem with diagnostic code system is, it only guides you in the right direction .. doesn't jump out slap you in the face and say" your cars spark plug is not working" ..in other words if it says glow plug control module that doesn't necassarily mean thats where the fault lies .. it could be a glow plug .. it could be a connection etc. etc. a mechanic should know this and not rely just on the code recieved .. but check all corresponding systems as well ?? hope this helps
