    confused Old problem still not solved - time to try again!

    Morning All,

    Well I am trying to resolve an ongoing issue with my 05 plate Veccy 1.9cdti (150) after it let me down and spoilt Boxing Day!

    The problem is that it doesnt run correctly and the good old EML came on (and stayed on) yesterday and was cured by a clean of the egr and the boost sensor (the one across from the egr at the back).

    I have no faith the the car now...this is a potted history

    The car has lost some performance for over 2-3 years now but noone can find any problems (my only gain a bit higher mpg). The EML comes on during start up but no error is shown, it does go out after a few secs. The car is on its 3rd egr valve,it has had the swirl valve and 3rd injection down and I believe the newer inlet manifold.

    Another 'fault' it has had for this period is the temperature doesnt really come above the 70 degree position, the car get warm but the3 gauge hardly rises - it used to sit nicely at the 12 oclock position. The engine tick over cam be lumpy and there is missing power spots through the revs. Another issues I am not sure is normal is a 'sucking noise' when running.

    I am looking at blanking the egr off this week and then looking at the BCS filter, I have changed one vac pipe a while ago but this did nothing. I think the cleaning of the egr is curing the symptoms and not the overall cause.

    I think that covers all the issues, any advice etc would be grateful I really do want to fix it this time to bring back the faith in the old beast.

    Thanks, Mark

    Vehicle : Mk1 renault scenic... I know I know but it drives

    Trim : Basic

    Engine : 1.6 16v

    Year : 2003

    You have several faults their mate all of which will probably account for a lack of performance

    first issue is you have 1 or more bad glow plugs

    second your thermostat or temp sensor have failed. This causing the car to run cold their fore you cannot run in closed loop.

    Address this issue and you may be able to solve lost power spots once ecu is fully looking for everything.
    But coupled with the sucking noise means you have an air leak somewhere.

    this can be solved by looking at engine live data etc.

    sorry I cannot give you a fix of go to x part and replace.

    but all what you have explained is more than fixed by any garage that bother to take time to look.

    thanks for the detailed reply....guess what some questions.....

    how do I check the glow plugs and what part of my problems are caused by this, oh and what sort of cost or diy job to fix?

    I guessed the thermostat was duff as it seems a common fault ... what problems is this causing me?

    in regard to the air leak what sort of live data and results should I be getting, I have a reader that shows some info.

    and finally is is worth me blanking off the egr yet or should I leave it and try to iron out the other issues.

    many thanks, mark

    The glow plugs is causing the spanner light to start.

    best tested with an ohm meter. Should see under 1 ohm for good one

    The thermostat is causing the heat problem. But it will also cause car to run rich and can cause it to not go closed loop (ecu looking for feed back from oxygen sensors)

    theirs various forms of data to look at. Oxygen sensor data,MAF and map, short & long term fuel trims . But I think you may get in accurate readings with thermostat being possibly failed.

    you could have and emissions check carried out. As the readings give and indication as to what's happening.

    you can also carefully use a propane torch and a length of hose to to check intake pipes for leaks (revs will change when propane is sucked in through leak)

    Blanking egr may give you a fault code. But it maybe worth a try.

    As another note when was the car last serviced?

    thanks for the quick reply.....

    to clarify the eml light on startup I thought this was due to an old fault being present....the light comes on for a few secs when starting but after a few days it disappears then comesback a few days later when I guess the fault returns.

    if I was to heck the glow plugs is it a case of disconnecting them when the engine is off and measuring the resistance?

    onto the thermostat.....my car gets warm after 4 to 5 miles but the gauge never goes off the bottom stop unless I get stuck in traffic.....is this typical for a fault

    the sucking noise is like sucking up an empty straw evert second or so....its intermittent. ..not sure where it is comingfrom.

    the car is serviced every feb with the mot but the services over the last 2 years have made no difference to the performance.

    i get the feeling the thermo stat needs to be job 1.....what sort of cost am I looking at

    finally a question for any ppl in the le11 area......any good garages that might be able to sort me out without selling body parts

    just had another thought .....the tickover is lumpy at times even when the engine has been running for miles.....revs drop down a little and it sounds rough.....doesnt stall but sounds like it might

    Aahh my bad I thought their was a possibility you had eml and spanner light mistaken.
    you are correct in that as far asi know it means a stored code but ahoukd bring up any codes showing not present when tested.

    yes it is a case of disconnecting power getting a good earth engine block is usually good enough and testing them. Usually around .5/.6 but under 1 ohm is considered good.

    Yes that's sounds to be thermostat.

    What you describe does sound like a split boost pipe somewhere. Obviously without hearing and driving car its hard to say for definate.
    it may well be worth paying a garage an hours diagnostic time for them to investigate.

    i would get thermostat changed as soon as you can.

    Im not sure on cost wise for thermostat as I haven't done one on that engine maybe someone else can help you out on that front.

    Try looking at the boost sensor how to. Am not sure of exact name for it sorry. And I'm on my phone so can't link to it.

    it could be partially sticking. And maybe worth a go a free try.

    how ever a boost leak will cause idle problems aswel

    The big ones going from turbo, inter cooler etc.

    you could also see if a local garage has a smoke pro machine that should show up and induction leaks within a matter of seconds
