Re: ECU Failure
Is this EGR valve problem related to what's being described in the "Oil on filter" thread (at the top of the diesel page)?
Just wondering if whether its the same clogging issue as described by others or nae.

Re: ECU Failure
Interesting isn't it? That was my thought too but I need to be very careful how I approach this with the dealer and Nissan.
Unfortunately even though I am always an optimist, I have absolutely no confidence in the enduring reliability of this particular vehicle - I wanted to hand it down to my eldest son when he started driving, but I cannot.
In comparison with all other vehicles I have owned, this one has had the most faults and an unbelievable time off the road. (The aircond compressor also failed earlier this year and was replaced).
I have my doubts too about the diesel engineering design from Renault as done on this model. Compare with VW (we have a 3yr Golf in our company fleet & it has been troublefree)
I have operated the vehicle in almost ideal diesel conditions - long runs, clean fuel etc.
Even some of the techs working at the dealer whom I have got to know well, subtly suggested I should trade in.

Re: ECU Failure

Sorry to here of the troubles
OK there is no such thing as a minor blockage of the EGR it is either open or closed, it is like soleniod valve. The warning light sensor goes off when the NOx levels get to high for the polution regs.
If you have a paper air filter remove it and see if it has oil stains - Dont bother if you have one of the K&N ones as the oil will not show
If it is stained then you have the oil blowback issue.
Hell I am going to be blunt - I know you have it! It is an inherant fault of all modern diesel engines that have to recirculate crankcase gases.This problem is not only limited to Nissan/Renault.
Suggest you read the oil thread issue to gain an understanding of it, to fix it they need to completely replace the EGR system,the air flow meter sensors, the turbo boost sensors, etc and completely clean the air intake system They have allready done this on my car under warranty. When they have cleaned it and make sure that they have by pulling off all of the ducting and having a look, install a provent filter, even though you think your car does not have the problem it will surprise you how much oil vapour there really is.
On the BP Ultra point they have only just started reproducing this after about a year without it - all they were selling in the meantime was their standard diesel through the ultra pumps!
Footnote hear to guys -
The new ultra diesel
IS NOT THE SAME AS THE OLD ULTRA DIESEL
The Cetane ratings are lower
My fuel rep tells me that it now just standard diesel with a flammable detergent mixed in when it is placed in the servo storage tank and not at the refinery
