Laguna 2 1.9 DCi Cutting Out

[Ricardo]

The ol faithful £250 Slaguna has served me well for nearly 6 months... Up until yesterday.

Since i've owned it, it's hesitated now and then ever so slightly and put it down to the EGR. Yesterday a couple of times on acceleration i had thick black smoke, then last night the STOP and battery light fIicked up and cut engine power then fired up again... Okaaaay, carried on driving, 5 miles later going round a corner it does it again at about 35mph, but more lights come on the dash, loses power, no power steering, still have lights.... Then cuts back in and warning lights turn off. But after that it's doing it every minute or so, i manage to get the car back home but baffled as to why it's doing it.

I'm now having to use the Clio to get to work which isn't ideal but getting me out of a situation. Can anyone pont me in the right direction

@CRM ?

 

[gtmatt]

have you got an obd reader ?? could be injector fault ?? pump ??


I get black smoke on boost , but I thing that's due to age and egr.

As Matt said your best bet is getting the ECU read. If it flashed up a STOP error on the dash there will be some information on the error that will save you tarting about

Thanks chaps, i just need to get my hands on an obd reader. I was thinking of buying a cheapie one off Ebay for the clio emissions light would it also do the basic fault codes for the Laguna? Need it back on the road so i'm not using the Clio as a workhorse again

 

[gtmatt]

ive got a cheap one off ebay I used it on my old clio 172 and ive used it on my scenic as well ,this is the one I use

Ok, had a play about after work and took the engine cover off. First thing the EGR area with the I/C pipe were covered in black oily gunk so I blasted this off with brake cleaner ( only thing to hand)

I've taken some pics, what I did find was a vacuum pipe blanked off and assume this runs somewhere. I checked the web for pics and it seems like it runs like the pic setup below. So pic with the hose as it is and pic as I think it should. Any reason why they'd blank it off? The car fired up no probs, after cleaning the area I drove it round the block and it seemed all ok and even ran without any juddering.

I also tested the battery and alternator just in case.
Battery: 12.25V
On Idle: 14.1V
Under Load: 13.96V

I don't know what that pipe is, but lets hope you got an easy win!

 

[Ricardo]

I'm gonna give it a run out tonight to see how she goes, i have breakdown cover just in case

I'd like to clean out the EGR valve when i get more time and will buy that code reader too as it's cheap. Fingers crossed it's sorted 'itself' out.

 

[Adey]

Defo looks like the pipe for the shutoff valve thing has come off, would cause a boost leak then.

 

[Ricardo]

That pipe was blanked off and been like it since i've owned it.

Had the code reader on it yesterday and there were a few stored faults, cleared them, took it for a drive then checked again for faults...... Nothing, so at the moment it starts ok and drives so i'll see how it goes from now on to see whether it does it again.

 

[gtmatt]

what where faults and where is the obd port mate ??

 

[Adey]

Obd port is in the lower part of the center console, below/behind the ash tray I think.

 

[Ricardo]

OBD port is under the ashtray Matt, there was a few stored faults. I can't remember but they were cleared and haven't come back

Thanks
