Car Drives Rough And Engine Light On For Citroen C4 55Reg Hatchback

[arak81]

When I took my car to Citroen Dealer for boot problem they ran the diagnostic test and reported me that Car drives rough and engine light on along with tailgate wiring needs replacing. I also realised that my car really vibrates way too much when idling. the mechanic who fixes my boot wiring also said me vibration is very unusual and he connected their diagnostic machine but couldn't come up with any decision and asked me if i could leave the car for one full day for him to check..he also said it could be air intake problem.   

I need to mention here that  am constantly having two fault codes which are P1351 and P0298. could these all be related with one specific problem?

 

By the way, when car is on move it doesn't vibrate.

I have taken my car to local garages and some of them said that may be my Fuel injector needs replacing because car is misfiring. and other guy sold me a fuel injector cleaner for £10 and said if he were me he would do this treatment before anything. well, car still vibrates and its too much. can anyone advise me if it is possible to check the fuel injector myself and if needed replace as well.

May be when coastline taxis is back on the site he will have a few ideas. How many miles has the car done now ?

[arak81]

Only 70k

I took my car to 4 different garages today..and most of them said that may be one of the injector is not working properly. hence it misfires. he also connected his computer and found engine fault code P1351...which i already know about... .another one said a some kind of sensor which locates at the back of the engine and it's very expensive to replace..but finally my nearest one said Flywheel is gone...Now i remember this vibration(especially clutch) problem has been persisting since i bought the car..just over the time it increases a bit..So I am bit convinced that there was nothing wrong with injector or any sensor otherwise engine would have pulled up some fault codes.

[paul.h]

I did a google search for some possible problems and they gave things such as the crankshaft pulley could be worn (some have a rubber insert that perishes), the clutch dmf could be worn, maybe a fuel injector fault, a worn engine mounting and there may be more. Of these the pulley one would be a relatively low cost one and may be part no. 0515T3 or 0515V8.

Thanks for your help.

 

The guy who said me about Flywheel also said about pulley..Therefore he put the car on ramp and went underneath to check visually and found that pulley was all right. he then asked me to put my hand on the place where flywheel was to feel the vibration while the engine was running.  If it is very expensive repair i won't go for it..cause i have a plan to change this car by next year around this time.

[paul.h]

If it is the flywheel and it needs changing then it could be £500 to £700 from what I have read on here. The clutch would be done at the same time. Probably for now you are best ignoring the problem unless anyone advises differently.

[arak81]

Thanks once again for the honest advice.

 

I have found DMF and clutch kit for £ 300 (http://www.ebay.co.uk/itm/261486855392?_trksid=p2060353.m1438.l2649&ssPageName=STRK%3AMEBIDX%3AIT)

 

and mechanic said he will charge me £150 for the labour. But still i don't think its worth repairing as the car runs okay..only when its in idle mode the car shakes. the door and the rear side of the car keep vibrating which is quite obvious. Saturday morning I will take my car to the mechanic who repaired  my tailgate wiring. he will have a good look and will give me the quote.

By the way, If i would have any problem with fuel injector would it not give me any fault code? tailgate mechanic already tested the fuel injector with his machine and he said nothing wrong with them.

[paul.h]

If there is a problem with one of the 4 fuel injectors you might get a fault code but I am not sure.

[arak81]

Can fault ccode P1351 be related with Fuel injector or glow plug faulty..Every mechanic saying different stories..some saying Dmf,some saying mounting and some saying engine is running with 3 cylinder and one of the injector is miss firing which causing this excessive vibration.

​​hi Arak been away for the week  so sort of catching up on posts now.  Whoever is doing your diagnostic need to do the following and the diagnostic machine will help them diagnose the  fault.

Once the diagnostic I plugged in they need to go to live data then injector adaptation this basically shows you what each injector is doing voltage/fuel  wise if you've got a injector off then you should see one injector showing higher reading than the others.

 We would then double check this with a manual leak off test. then it would be sent to a injector specialist for a 3rd check and recon if needed

 

My advice to you would be to check/clean the egr valve as this causes all kind of rough running problem also all  rubber vacuum pipes.

 

Reading your post was the fault/light on before you took it into the garage or did they cause it when doing the boot repair

[arak81]

Thanks coastline taxis.

 

No one is doing diagnostic for the fault yet. I just have been few mechanics and they connected their small diagnostic tool to find out any code related with injection problem. they didn't find any code apart from P1351. So I am wondering if that code indicates about any fuel injector being faulty. The car has been put on the ramp and mounts are being checked, they all are fine.. finally one guy said my car sounds running by three cylinders.. .so it must be one of the injector being not working properly.

The clutch pedal was vibrating since i bought this car last year October. But the whole car vibration has started few weeks ago..may be a month or so before tailgate problem....

 

Are these jobs DIY to clean egr valve and all the other rubber vacuum pipe?

[arak81]

I took the car to another mechanic and he unplugged all the diesel injectors one by one to check if car is loosing any power or if there is any injector not working...after that he plugged them back on and since then my vibration  reduced a lot..but still I have got my top right engine mount replaced. mechanic said little bit of vibration is normal for a diesel car.

 

but something clicked on my head.  Fuel injector unplugging and re-plugging has reduced the vibration,...can i not clean the plug and the fuel injector properly to see if it improves..does anyone know how and with what to clean them?

[paul.h]

There is some very basic info here on injector cleaning but I would imagine it is not as simple as suggested http://www.ebay.co.uk/gds/How-to-Refurbish-a-Diesel-Injector-/10000000177770568/g.html

[coastline taxis]

its not a DIY job all you can really do is put injector cleaner in with your fuel

[arak81]

Thanks both Paul.h and coastline taxis. I'll do so.

By the way, Do glow plugs relate with car being driven rough? My fault code P1351 is still exist and i have decided to change the glow plugs (all four of them). Just wondering what benefit I may have if i change them...and one more thing I have replaced battery just couple of weeks ago and still i can see that car goes to economy mode , sometime i can't operate the window while ignition is on unless i start the engine. 

[paul.h]

New glow plugs may help a bit on the first few minutes of starting the engine, especially when the weather gets cold again.

 

With a charged battery, from our experience, economy mode ought to cut in about 15 to 30 minutes after stopping the engine. When in economy mode I think the electric windows will not work.

[arak81]

I have had my glow plugs replaced...and look at the old glow plugs in the picture below.

 

So definitely if there is any fault code P1351 it must be glow plugs broken.. mine were badly broken.

 

 

By the way, My mechanic friend diagnosed my car and found P0422 (Maximum number of aborted regenerations) and P1728 (CAN Engine torque Implausible) though engine light was not on. Can anyone tell me if these codes were generated because of the spray (Wynes Turbo Cleaner) that I used through the air hose to clean the Turbo?

Hi,

fault code P1351 has come back..mechanic said it could be because of Aftermarket product that we used..I have found original one which you can see in the picture (made in Germany). Can anyone advise me plz..

[arak81]

Are you on holiday paul.h?

[paul.h]

I have reached the limit of my knowledge on this topic so I can not suggest anything else other than suggest you visit a dealer.

[arak81]

Got it sorted. Eventually the glow plugs i used were low quality and even one of them were faulty. hence fault code P1351 came back. we found out these when mechanic replaced them with Hidria Glow Plugs bought from eurocarparts. Since yesterday i couldn't see fault code p1351 comes back..hopefully its sorted now. anyone with similar problem make sure use the right and quality glow plugs. otherwise you have to pay twice to the mechanic to sort it out.

[arak81]

Had my flywheel and clutch kit replaced today. now there is no more vibration and I am sooo happy....it didn't cost me as much as i thought. thanks to the mechanic.
