Hi,
I have a renault trafic 1.9 dci 100, year 2005.
8 months ago the glow lamp started to get on and off now and then, the manual says it is either a water in the deisel filter or another more serious reason. I just replaced the filter (and of course all the accumulated water within) and every thing went well, the lights went off permanently.
Last couple of week the lights (glow lams) showed of again, also come and go, when I visited the garage (for another reason) I told the mechanic about it, he told just to ignore it.
Last week my car got in the limp mode ; low rpm no matter how far I press the paddle, no power , maximum speed was 40 km/h, of course the glow lamp was on, and hardly managed to reach home.
I searched the net for hours to find a solution, found many diffirent opinions but the majority of them was to blame the EGR and MAF.
For me - I am not a specialist- it was the first time hearing of the EGR and the MAF, so I started a new search to see what they are, I saw many pages explain how to clean/change them, many youtubes also show how to. At first I was hesitated to do it myself or just bring it to the garage, I had no idea how difficult it would be, at last I decided to get my hands in dirt and do it by myself.
I started with the MAF because I thought it is easier and to judge my knowladge in mechanich, I was surpriced how easy it could be ! Withen minutes the maf was out and on th ground ! This unexpected seccess tempted me to give the egr a try , especially the motor upper plastic cover was open and the air-filter-box was removed (to reach the maf) and Im looking at the egr directly in front of me, so there were just three bolts and holla… the egr was on the floor!
I was shocked because of what I found in egr and its host : a ton of a black carbon, no openning or spring or aperture was there, just a black block of carbon.
Following the instruction which I read, and the movies on youtube, I cleaned bothe of the MAF and the EGR, reinstalled them back and run the car… . but the glow lamp still there ! Switched the car off and run it again and holllaaaaa, the light went of permanently !!
My advice here is this : if you can use a rench and have a 30 minutes to open these two 20 min to clean, and another 20 min to reinstall then make yourself -and your car- a favour by doing it yourself, that would save you a lot of money and time, even if it doesn't work for your car, then you just gave it a necessary service that it needs.
