"Check Injection" and Service light on when I hit 3200rpm.

Postby leadhead » Fri Mar 10, 2017 11:50 pm

Of course the easy answer is..."Dont do over 3100rpm"...
I bought the car last week in a supposed private sale. Since then I have noticed him selling another car, and more investigation has shown he's advertised around 100 cars in the last year....a bit more than your average "private seller".
Apart from the "check injection" problem, one of the windows doesnt work either....Now if it were a Private sale, then I would just have to bite the bullet, but have been told that if I can prove hes a trader, I have a month to "ask him to repair it at his cost".....IS THIS TRUE....

I am pleased with the car, £30 road tax and in my first 500 miles, just under 60mpg.... The 3200rpm happened tonight while accelerating in 4th gear. It also happens when i drive at 70mph for a few minutes. The light doesnt come on when its just started, and I can avoid the light coming on at all if I avoid quick acceleration, or cruising at 70mph...When the mesage comes on, I feel as though the engine has gone into a mode that slowed it down a bit....After I stop and restart, the warning and service lights disappear. I read about the glow plugs, but mine doesnt happen when cold starting.

Tonight while out, I thought I heard the engine making "cuckoo" noises at me and realised it was when I accelerated(the "cuc") and then decelerated (the "koo"...)...This doesnt bother me..if its not harming anything....just wondered if any other members have the same noises and know what it is...

Thanks for reading my first "problem" post...I hope you can help me.

Hi,
he must be a trader if his name is not on the ownership docs.
Depending on how much you paid it could still be a bargain but there again you could be heading for trouble. Remember very little is cheap nowadays.
You've got nothing to lose by having a word with him and see if he is fair.
ln future l would recommend to deal with those who say they are a trader, you can still get a bargain.
Good luck
Bob.

Hi..thanks for the above...funnily enough I've looked at a few of these and to be honest(and respect to all honest traders)...most of the cars I've driven/looked at that were advertised by traders, all had something that I managed to point out to the seller, that they swore they knew nothing about. I believe there's good and bad in both private and trade sellers, I suppose the only difference being(hopefully) that a trader is obliged by law(I hope) to correct anything that they havent disclosed to the buyer.(Ive still not managed to find out if THIS is law)

His name wasn't on the V5, because he said he'd only had it a few days after part exing it against his own private car...Obviously this raised a bit of an alarm, but for £800, the car looked good,had a new water pump/cam belt, was regularly serviced(if book is correct), handled well, everything seemed ok, and I was without transport and needed a car...and had missed a few. Had i not taken it over 3100 rpm, or cruised at 70, then a still may not have spotted this...but even with this, i still dont want my money back, but would like it investigated at his expense. I could actually live with the faults as long as it isnt going to get worse.

Thats the start of the egr sticking. Get the egr off, give it a good clean, big chunks will come out of it and free off the plunger with plenty of easing fluid, gt85 wd40 etc etc.

If you want to fix it and never have to worry about it again, buy a cheap used egr and plug it into the plug and cable tie it somewhere in the engine bay but out of the way. This will allow the egr to still work and keep the light off on the dash but cos its opening in fresh air and not in the inlet manifold it wont coke the inlet up and become blocked again!

Hi again,
it sounds like it might be a good bargain, it could be the egr, but if l were you l'd get the codes read first.
lf you don't know anybody who can do it, or get it done cheap, it's a good idea to get a reader yourself, you need one nowadays.
lt should give an indication on what's wrong instead of stabbing in the dark so to speak.

Thanks for this, I'll have to wait for my manual arriving, as at the moment I dont even know where the EGR is. I remember doing something similar to the BMW engine in my Rover 75, which was quite easy.....

I've been tempted to buy a reader but always had access to the proper Rover T4, so didnt bother, but will look into it again...
Definately better than "stabbing in the dark"...

My code reader arrived today....was told unless you buy really expensive, the cheap ones are supposedly all as good as each other. I bought a Maxiscan MS300 off ebay for less than a tenner.

On starting I got 2 codes up, 1 actual and 1 pending, but both the same...P0381, which the booklet says is a
Glow Plug/Heater Indicator Circuit Malfunction... It starts every time with no bother, during cold mornings it maybe takes 5 seconds from me pressing the start button to the engine turning over and starting(always first time...touch wood)..... My "check injection" warning only comes on when I accelerate in lower gears and the revs go over 3000, or when I take it over 70 for a while in 4th gear....5th or 6th gear doesn't bring on the warning.....(it didnt yesterday) These incidences are well past the stage I would have thought the glow plugs would affect anything...

On actually driving the car until my "check Injection" warning comes on I noticed a pending code of P2263 came on.

I've just found this article referring to the above code.....it would be nice if it were something as easy as the first solution(replacing the fuel filler cap)....although theres no actual cap on mine... https://p2263.enginetroublecode.com/renault-megane Its a US site...Would be nice if there was a UK one, or a thread on here explaining all the different code meanings...

Has anyone else dealt with these codes, and is it really necessary for me to be concerned about them, as I can avoid the "check injection" fault by driving a bit wiser.

ADDENDUM After loads of searching, I found this site which lists (and searches for) loads of codes https://www.troublecodes.net/ccodes/

The site brought up this explanation of my P2263 code...Turbocharger (TC) boost pressure/supercharger (8C) boost pressure - performance problem....As I noted that the fault only came on at certain rpm...then maybe this is the point that the turbo kicks in....Hopefully someone cleverer than me reads this page and can tell me what it really means, and whether I should be worried about it.

Hi there,
l've got the 1.9 dci with 6 gears so rarely go over 2,000 revs.
As l understand, the boost pressure sensor is the same as a MAP sensor. My guess is that it needs cleaning, or the inlet manifold needs cleaning out.
The EGR dumps exhaust into it and they can get clogged up thus restricting the air flow.
There's a good picture of the boost sensor on youtube and it's easily accessable, lookup 'change boost pressure sensor Renault'.

Thanks again Bob...Mine too is 6 gears but only the 1.5l...To be honest I CAN avoid 3000 rpm...but am wondering if it will only get worse and eventually go down and down, and come on at say 2000rpm

I remember my Escort Mexico days of the '70s when I could whip the engine in and out in a day, now unfortunately, I've got no where to work and haven't got the know how and patience with these modern engines and can't afford to get it done in a garage. I'm taking all this information in, will certainly look at the online video and will build a list of things to do...so far its all "cleaning bits up" ...which hopefully I'll get done....hopefully with someone with knowledge of what to do.

I took it out today after giving it a stiff Redex dose...I made the fault come on, but then stopped, switched off, got rid of the light, then revved the car up a few times to 4000rpm and couldnt get the light to come on while standing still, although I can still get it to come on while moving...I wonder if theres any significance in that.

Ive just watched that video....I wish all jobs were that easy, but having said that, your oil filler is in a completely different position to mine, so just wondering if all other components are also in a different position to the 1.9l. I'll try and find a similar video for the 1.5l.....but thanks again

The egr on the 1.5 is easy to get to. Take the engine cover off and its more or less infront of the drivers seat on the back of the engine. Its built into the inlet manifold

Got round to looking at the boost sensor today...although it looks completely different on my 1.5 than it does on the youtube video of the 1.9. The actual shape didnt worry me, but the bit that goes into the air pipe didnt have the needle in it, or the holes in the sides...it was basically just a nipple with a rubber sealing ring on it....so really there was nothing to clean, but I put a rag in both ends and cleaned what i could. I took the car down the road and lo and behold, the warning or service light didnt come on....but(see next bit)

Nothing on my motor looks the same as the photos I look at(supposedly of the 1.5dci) in the manual or on youtube....I cannot find an EGR that looks like mine...all of the newer ones I see are connected horizontally with nuts on bolts....mine is connected vertically using 3 bolts, and for the life of me I cant manage to disconnect the electrical connection.....and in fumbling around with it, may have avtually damaged it....although theres no warning lights on the dashboard...I wonder if the engine bits in the later 57 models have been modified in some way, and are different to the ones shown in the manual or the youtube videos...Ive searched for photos/videos of the 57 dci engine...to no avail.

Addendum Went out today(day after I wrote above) and "check injectors" and "Service" light both came on as usual......so no miracle cure as hoped

Hi again,
you could have just one glowplug out, or even a bad connection, the computer can only detect differences in voltage/current etc or dead circuits.
Each code needs investigating, even though it starts ok
This could be the cause of the check injector code, when an injector goes wrong the glowplug symbol lights up.
As for the sensor, they work in different ways to how we think, sometimes just a clean in petrol or contact spray can make a difference.
l've a feeling, and it's only my opinion, that the egr and the inlet manifold need cleaning out completely.(no 5 minute jobs)
l know that the car runs ok, it may be only a concern when the car is revved up for the mot.

The 1.5 dci was used in the Micra so you could try that line on you tube and see if it looks like yours.
Good luck
Bob.

I thought about this, and wondered if it would fail on its emissions, but when I rev up when either standing still or moving with the clutch in, the "check injection" light doesnt come on....so as it only comes on under load, it shouldnt(hopefully) be a problem during the MOT.

I've finally found a picture of the exact EGR valve on my motor...I still cant find anything on Youtube that shows how to clean this particular EGR, but would hope its fairly straightforward. I would appreciate any advice from anyone that has had experience with this type of EGR as at the moment I've no idea
