Renault Megane dCi "Injection Fault"

Damokc

The girlfriends car, which she only bought a week or so ago has started getting this popping up on the dash;

"Injection Fault" and "STOP" light comes on + a drop in power. i presume its going into "limp" mode to save the turbo? havnt driven it myself yet.will get back with more details tomorrow.

i've looked around on line and this seems to be a huge problem with these cars?online people seem to say its anything from the injectors to the battery to glow plugs to fuel pump to leak in the fuel hose to the actual fuel tank...no definitive cause.....but all have the same warning signals.

Has anyone here had the problem and how did you fix it?

car : 04 Renault Megane 1.5 dCi 99,400 miles. timing belt and water pump done 19/3/2011.

The fault light covers a few things, from simple to a bit more serious. Check the simple things first. Does the battery look original?I doubt it's that though cos it probably would have issues starting. but sure it costs nothign to stick a multimeter across it and check. Ìf you know anyone with a fault code reader, even the cheap ones, it could help point the way too.

Did she have the timeing belt done or was this while the garage or whover it was bought from still had it? The 19th was only last friday afterall.

Damokc

cheers for the reply.

she got it done herself after buying it. bought it on the 9th,timing belt/water pump was done on the 19th. will check a few things tomorrow. i drive a 1998 honda so im not really up wit specific warning lights. the only warning light i ever get is the orange "low petrol" light!!....... touch wood.:P

The fault is because the ECU is seeing low fuel pressure in the fuel rail.Now if its due to faulty injectors or fuel pump,its going to cost huge money.Hopefully it wont need the above replaced,but if it does be prepared!!

Faulty injectors is a common problem on the 1.5dci engines...

Ah but the Renault fanbois insist that all Renaults are properly built since 2005 and that Renault's reputation for unreliability is a hang up from 20 years ago and really that we're (as in those of us on motors that say you shouldn't buy a Renault because it may break down) ignorant sods for pointing out that they are not the best cars in the old reliaiblity stakes, so surely this must be some mistake;)?

Ah but in your haste to be smug you missed the fact that the car is an 04

I suspect the mechanic didn't refit something properly and it has worked loose or got damaged.
There's a sensor for the high pressure pump position on the timing belt cover which must be disconnected to get at the belt, he may not have reconnected it properly or left in a way to become damaged. Another possibility is that he undo the glow plugs or injectors to make hand-cranking the engine easier and forgot to re-tighten.(according the Haynes manual Renault say you must replace an injector pipe if you ever loosen it).

Anyone who says there have been any well built renaults after the last generation of cars finished in about 01/02 obviously doesn't work in a garage!

right...."injection fault" message hasnt come up since tuesday but now the "Service" and "stop" messages are on constantly?

any views bar stopping and servicing it as its not due a service for another 3k miles?

The car will have fault codes stored for whatever error condition is detected. It needs to be scanned by someone with a suitable scantool. It could be any one of a number of things wrong. It will not be possible to figure out what it is just by looking at those warning lights...;)

Why don't people STOP when a stop light comes up on their dash.

Renault don't include them for the crack you know.

This happened to my 07 Megane last year. 'Injection Fault' came on and the car would go into 'Limp' mode every so often. In the end it turned out the throttle body needed to be replaced. That turned out to be a €450 kick in the nuts so I'd suggest getting it to a garage to have someone take a proper look at it.

If its a injector problem they cost €400-€450 EACH alone on parts, not including labour, dignostics etc...! Its going to be pricey because there a absolute heap of dirt of a engine.

sit_casper

I currently have the same problem - apparently the diesel pumps on these cars are prone to failing. The garage just told me that my pump needed replacing along witht the fuel lines and injectors. gona cost in the region of 3k.

You have many answers as to your problem but really your just shooting in the dark until you get the car plugged in to see what error codes are showing up and also to see the live data from the engine control unit.its only 10 mins work for a good techie to plug in and evaluate the codes and live data to point you in the right direction.

After seeing a friends parents 2010 megane suffer from engine failure, only to be fixed and fail again a week later - I find any claims about renaults being well built as laughable.

That's over a €100 per injector cheaper than a B6 Passat, which is also a boat anchor of an engine, so be glad it's not a Volkswagen....

I've come across this through a contact on a fleet. Interestingly, there is a geographical element into this problem, and the suspect is diesel quality.......

'engine failure' doesn't tell us anything about how/why - For the same reason anyone running an 09 Audi Multitronic would have not dissimilar views on 'quality'.....

Atlantic Diesel

We remanufacture Delphi dci injectors for €120-€150 each.
As to the passat I'm guessing its the siemens Electronic unit injector (pd) that is the problem and yes they are expensive.

from your experience "galwaytt"would i be rite in saying that geographically it would be more of a problem in the northern half of the country!

I would say more the part of Europe are in but I could be wrong....
Ireland isn't known for its high quallity Diesel.

Suffering exact same issues. Did you get it resolved? The noise of the stop light in low gears is slowly driving me over the edge!
