Megane DCI nightmare
Posted: Wed Dec 18, 2013 9:42 am
Hi, I am new to the forum and was wondering if you could help.
I have had a megane 1.9 DCI for a few years, been a pretty good car, but not without a few problems.
It started around a year ago and occasionally would come up with "check injection" when driving and lose power, when turned off and on it would be ok for a while. I never did anything with it as it was so intermittent. Then a few month ago the turbo was noisy, it didnt run off its own oil, i switched it off and didnt run it. I removed the turbo and the inlet side bearing had collapsed. I bought a reconditioned turbo, with new gaskets and oil pipe. I have fitted it but had problems since. I fitted it and drove it and it had no power. I checked the vac pipes and think i had rooted them wrong, I think they are right now but not a 100% sure. I have drew a diagram as to how i have got it.
1) I still have no power and "check injection" on constantly. I have got a code reader, read the code P0409, which is EGR, i have cleared it, but still got the ligtht on and now the code reader says no codes.
2) The turbo actuator never moves on start up or engine off.
3) the vac pipe to the actuator has vacuum there, but not much.
4) there is small valve under the vac reservoir, it has 3 pipes connectors, but i only have 2 pipes to go to it!
I know its a long story but wondered if anyone can offer any help or advise, I have been trying to find someone with the same car to look and see if the same but cant.
