D5 (D5244T to 2005) - Random engine cutout! - Page 2

TylerWatts · Apr 18th, 2012, 21:13

Hello gents. Back from hols, survived ok, though car got worse and worse towards end of trip, cutting out randomly, but fortunately re-'starting' every time. Engien dies whenever it feels like, usually when going from idle, or more frequently from neutral throttle/coast to gentle power. Flooring it doesn't usually present the problem.

Volvo could not pull any code off the ECU today indicating anything about the engine cutting out, though the day before my holiday a mechanic pulled a generic code saying "820A main relay switch", which I believe to be the same fault as suggested above.

Does anyone know what the fix for the faulty fuse/relay panel/box was please? Was there a revised part number, or just new ones fitted? Can I fix the problem myself?

Also, Volvo pulled 2 codes: ECM-2501 and ECM-2502, both "Fuel pressure - Pressure too high", any idea what these pertain to? The Mechanic said before the holiday that the fuel pressure regulator solenoid is a frequent culprit of poor performance and economy as it fails. ~£250 to replace though!!!

PS, Fuel filter was replaced recently, when Volvo first looked at the car for this problem, didn't do much to improve anything.

I dont think your problem is fuel delivery related.
There's no need to change the fusebox, it can be checked and tested to confirm that is the problem, and so far they all were repairable. I would say its a rare problem, but not unheard of.

We're in Mansfield and I'm pretty sure we can fix the problem you have.

Have you checked the condition of the injectors?

Hi, ref the last post just to share my experience of similar issue..
Car was diesel grand voyager, would cut out sometimes when driving but usually when slowing. Sometimes restarted easily other times only with easy start. But would then run well. No codes. At least three times to main dealer who were contacting head office tech. Also tried local infependent. Theory was electronic issue (also can bus) or fuel inc lift pump.
IT was also convinced looking for electronic problem and was using OBD and circuit diagrams to try and fault find .

Eventually a diesel specialist solved the problem in 30mins with 1 or 2 injectors that were out of spec. As it was a mechanical prob with injectors did not show up on anything.. But diagnosed with simple milk bottle test..

Hello gents, thanks for the replies!

Dera, I'll certainly be in touch!

v_matt_v, the Injectors were all replaced 2.5 years ago, with brand spanking new Bosch units, not freakin cheap either! They have sounded a bit loud, and I'm looking at having them cleaned, but they should not cause engine cut-out.

Basically the engine dies, dash shuts off for an instant, then back on as if the ignition was switched off then back on, and if the engine was running fast enough it fires back up and keeps going, but sometimes when idling or pulling off the engine cuts out and needs restarting.

thePM, as I said to Matt, they are fairly new, maybe need a clean, I ran some expensive Fuel System cleaner through the last tank, not made much difference, maybe slightly cleaner engine pick-up, but hard to tell on the auto.

So I'll be in touch with Dera about testing the fuse box, and let everyone know how it goes.

Thanks again for the great help!

Regards
Tyler

When the dash shuts off do you lose everything including Speedo and rev going to zero before warning lights come on?

In this case I misunderstood the situation and agree there is no way that a fault with injectors could cause this. When we were looking for a can bus problem there was the possibility of connecting can bus diagnostics whilst driving.

Just a thought - could it be an immobiliser issue - does it happen with both keys. I understand that there is an ignition/immobiliser module on the can bus and input from this is needed by the ECU to allow the car to keep running. Hopefully one of the very well informed members on this forum may be able to comment further..

Best wishes for getting this sorted - pls keep everyone updated.

thePM, no warning lights, no faults shown, it is a momentary shut-down, ie maybe up to a second long, as if ignition was switched off then back on, radio and Climate Control etc keep working though, so maybe it is an immobiliser problem.
I will discuss/visit with Shark Motorsport and see what they can diagnose.
I will also try the second key, it's hardly ever used, so this one might be a bit bashed up from drops and 10 years' use...

Thanks for the suggestion, it's so easy to overlook simple things like that.

You could do a leak off test on the injectors and also test the in tank pump easily yourself at virtually no cost . The symptoms do not sound like the in tank pump or problems with injectors , I cannot think of any fault in these two items which would cause the electronics to act up the way you describe . The CEM and dashboard end fuseboard got soaked on my V70 D5 a few months ago , water came running out when I opened the OBD socket cover which was quite a surprise . I used a hairdryer on it , seems ok now and still do not know how the water got in , no leaks around the windscreen etc that I can see .

Folks, sorry for not posting results!

Spare key worked a charm, not had any issue since trying it. I simply don't use the original key anymore, andkeep it for emergencies.

Was contacted by text today to ask if I'd sorted it so wanted to post the infor for others to help. Again, sorry I did not respond sooner.

THANK YOU to all who helped! Who knew it was so simple, after spending £ks trying to replace potentially suspect parts... Am, trying to sell off some of those parts now, as the Parts suppleirs love to state "it's been fitted, it's not new anymore" even though I bought some parts the other day that'd clearly been fitted (most likely a dealer returned them after they didn't fix a problem) and wanted to feed them to the sales man behind the desk!!! Rant over, sorry.

Thanks again!

Hi.
I am new to the forum, but am suffering the same intermitent engine cut out. Garage has not been able to find any faults, so I have just changed keys, and hope this fixes the problem.
