Engine will not fire , running fine then went pop

[den9112]

Hi, I have a Meganne tourer 1.5dci 2006 with 90k , two days ago we had the EGR recycling valve replaced ,£110 for part and £150 to fit I picked the car up yesterday and all was fine apart from taking it back with a check auto light message ,that was sorted , I have done approx. 50 miles and was just turning in to my drive tonight and I heard a pop (the sort of sound when you go over a empty plastic milk bottle) I then limped up the drive stopped then turned engine off I then tried to start and it wouldn't ,no messages on dashboard at all,i eventually called the recovery service who tried to start but couldn't, he put is computer on the car and it said glow plug circuit fault ,could anyone please advice on what I can do, any help or advice on the matter would really be appreciated.Thanks

A £150 to change the ERG valve , 3 bolts and a plug, that's day light robbery , I would have thought £ 150 to supply and fit ,

Hi, on the bill it says one recycle pipe at a cost of £110 and £150 labour

[den9112]

I have scoured the internet and still cant come up with anything, this is now becoming a nightmare after spending a fortune on the car ,clock spring ,new front and rear rear pads ,just been serviced as well I am thinking of just putting the damn thing up for sale as it is ,its MOT and taxed as no one will take it as a P/X could anyone advice on getting shut of it ,this car caused so much stress for us all yesterday (xmas day) , I suppose ebay is the only answer.

Very recently we came across a similar problem on a 307 hdi Peugeot dmf flywheel breaking & taking out the top dead centre sensor. Would'nt do any harm to check out tdc sensor at the ecu whilst cranking.

[den9112]

Thanks for taking time to reply ,could you please tell me were it is situated and what to to look for while it is being cranked.Thanks

The engine kept running after the pop. Hence, it is not the TDC sensor, and not the belt (is it true?). It is not clear from the description whether the engine turns over during the attempts to start it or not. Please elaborate.

These engines are supposed to start, although with some difficulty, if the glow plugs fail.

As the OP is clearly not a competent person, the best course of action is to find a good independent local garage. Please do not go back to the place where they ripped you off! This dodgy garage may have introduced a new fault.

Check the hatch cover on the front left wheel arch liner, all fuses (including under the bonnet), the clear pipe to the high pressure fuel pump for bubbles of air, and oil colour/level.

Hi Alex, I can assure I am a competent person in the line of work I do, electrics and fault finding are not my strong point especially on Renaults , back on the matter, the engine turns over strongly and was running great prior to issue,the noise when I lost acceleration was like going over a empty plastic milk bottle .

Hi Den9112,

I am sure you are a competent person in your own line of work. I was referring to paying silly money for a job, instead of which one could just clean the part, and winging about the pads, which are only an indicator of how much fun one has when driving. Perhaps I misunderstood you. Never mind, and still consider finding a good independent garage locally instead of the one with funny prices.

Back to the technical issues. I shall paraphrase - did the engine continue running for at least some time after the "pop". If yes, then were there any lights, sounds, smells or anything unusual at all which you noticed? I mean directly after the pop and before you pressed Stop?

I'm quoting the following from my previous message, please do it.

H Alex ., the car as been towed in the garage were I take it for its MOT and general repairs ,the car when it broke down got me a few metres were it struggled to get up the slight incline ,then I lost throttle power so it did run on a bit before giving up ,after pressing the stop button and then attempting to restart It just didn't want to attempt starting , no smells or warning lights at all ,all I can say is all was ok apart from firing up,i checked all the electrical equipment in the car ,heater lights alarm etc all ok,when the green flag guy came out he was under the bonnet and asked me to start the engine a few times ,at one point it seemed to want to start but that was short lived,he then put the machine on and came up with glow plug circuit fault,...........I have just come back from garage were they will have a proper look tomorrow as they have been busy but it tells me he took the oil cap off and rocker and smoke came out(exhaust smelling ) while firing it up ,something about pressure , it just seems a coincidence that this as happened after the new part was put on,as I have never had a problem with this car starting , especially last winter were it started bang on when the temp was -9 degrees for at least a week ,PS he also sais it was getting fuel .

a pop sound followed by a no responsive gas pedal and struggling to keep alive. after that no more starts but the engine spins fine. i think this is what you have until now.

there isnt too much things to pop on that engine, pretty much there are pipes to blow, here are the list i remember:

turbo - intercooler pipe
exhaust gas for EGR (its metal pipe but very thin),
water pipes
air intake pipe
intercooler - air inlet manifold pipe (where the EGR is fitted)
the manifold it self acts lije a pipe
aluminum pipe that comes out of that manifold to the cylinder head
fuel pipes

On none of these, except the last one, i cannot see why the car doesnt start, like Alex told, it would start but with a bounce or two, even with that glow plugs problem..

Now, there are pipes that can in fact cause problems and will not warn you on the dash and the car will not start for sure, the fuel pipes. and In this chapter it is possible to swap the inlet with the out let on the fuel filter and that will produce a POP on the filter (cracking) and caput fuel to the engine.

Did you serviced the car?

[den9112]

Hi Thanks for the reply on the pipes,the car was purchased from Renault with 35k with a full service and cam belt change when it left the garage ,it was serviced twice again by Renault in the year I had the warranty ,in that time it had lots of jobs done with Renault ,AC upgrade wiring kit,window regulators ,clockspring,wiper motor and a leak issue with the diesel pipes ,that was also supposed to be a recall,after the warranty it went back to Renault for another service at the normal interval ,Renault (burnley the went bust) and after that it went to my local garage were it as been serviced at the correct interval ,also new brake pads and discs all round ,when I had the initial problem with EGR recylcling pipe that cost £10o and £150 for fitting it was xmas eve and I was a long way from my local garage and it just happened very near to a garage who repaired it quickly for me to allow me to get back on the road ,that's the only time the car as gone to another garage since I have owned it,any sound or unusyal smell and its gone straight in to the garage to be looked at ,last service was done one month ago .

OK, the next is to plug the OBD reader and look at the rail pressure and revs (live readings) while attempting to start the engine.

Before ding this, make sure that the intake is not obstructed.

Thus, you will check the crucial things needed to start the engine: air, fuel supply and timing.
