05 D5 diesel cutting out... - Waino
A problem that's bothering my ol' mate Tony .....

Anybody out there experienced this problem with a Volvo S80 (51;Oct 2001) with the D5 diesel engine? Intermittent fault, engine cuts out for .5sec, all orange warning lights come on before the engine restarts if going at more than 25mph. If going slowly, it stalls, but restarts with a first turn of the ignition. Very unnerving!!.

About 200 miles after a new fuel relay was put in by the Volvo main agent the problem occurred again 20 times in 100 miles, no trouble today although it blinked twice yesterday. No link to engine temperature, no sluggish forewarning just a shut down for a fraction of a second. Electrical ?

Computer analysis says tough luck or words to that effect. and the garage is still mystified.

Any suggestions would be gratefully received. Cheers and Christmas greetings, Waino.

Sounds electrical; but there are many candidates. Cam/crank sensor; fuel-rail pressure sensor; [or their connexions;] the ECU itself; a loose feed connexion; a wiring loom break; or a bad/broken earth.

Hopefully; it'll stop completely, or cut for long enough to flag a code, as it's not going to be easy to track that down unless they've seen it before.

Thanks for your reply to this question, Screwloose. I was waiting to see if there were enough Backroom Volvo drivers to have possibly encountered this problem - certain models often seem to thow up certain faults. It may be that there aren't so many S80 owners; maybe it's not a common enough problem or simply that the Volvo drivers are all settled down with the grandchildren over the festive period and are keeping their heads down ;-).

Apparently the problem is still there and, as you say, the intermittent ones are always the worst to identify!

If we discover the fault, I'll let the backroom know.

Hi there,

I've got a Volvo S80 2.5D which is a April 2001 on a 'Y' plate. It has 151k on the clock and has just been serviced and MOT'd.

On New Years Eve (of all days) without any prior warning it decided to display the two following error messages:

'Engine Service Required'
'Engine System Fix Next Service'

It also displayed the red warning triangle as well as the engine symbol on the dashboard at the same time.

I managed to get another 6-miles at reduced speed (went from 70mph to 20mph almost instantly!) to some services on the A64 near York.
From there I contacted the RAC who arrived fairly promptly considering the time of year. He tried to get his laptop to 'talk' to the onboard ECU via the docking port, without any success.
He arranged for me and stricken Volvo to be recovered home (approx. 40-miles). I finally got home at 10:00pm (set off from work at 5:00pm), and then had to wait until 3rd Jan before local garage (a good one as well) could look at it.

They tried to get both of their diagnostic computers to 'talk' to the ECU, again without success. Apparently it kept blowing a fuse everytime they hooked up the diagnostics. Also twice when moving it out of the service bay it stalled, even though a 2.5D should have enough torque to move on tickover, never mind using any revs.

It's now awaiting the RAC to take it to the independent Volvo specialist near where I work for them to hook up with the actual Volvo diagnostic gear to see if they can obtain the error code?

Having checked on Google regarding those two messages, it would appear to be something called the ETM (Electronic Throttle Module?), which looks very expensive to repair (approx. £650+), which for a car probably only worth £2000 is not really worth doing?

Hope this helps, also if anyone has experienced something similiar, and knows a cure other than the ETM, please get in touch.

Cheers

James

I don't think that you've got enough there to make any firm diagnosis yet. Those are just generic messages flagged-up by the ECU after it's detected some - unspecified - fault.

Clearly; the fault is serious enough for it to have engaged limited operation strategy and I'm mystified that the ECU now won't talk. On that year, it would have EOBD as well as Volvo-specific protocols and they should communicate with any professional scanner.

The blowing fuse could be a clue; there may have been a loss of feed to one of the ECUs inputs - or even an earth problem. All that needs checking-out before any parts are ordered.

Hi there,

Got the car back today after taking it to an independant Volvo specialist in York called Dyrdals.
I bought the car from there in December 2006, and they're a good family owned business that don't try to rip people off.

The RAC took the car there for me on Monday morning, and Dyrdals have been checking through various things before finally locating the fault. Here's what they found:

A turbo pipe and valve were found to be faulty, also a small piece of electronics related to it had burnt out (this was causing the short circuit that kept blowing the fuse). The faulty turbo pipe and valve have been replaced, and driving home tonight there was quite a difference!

For the last 12-months, everytime i've pressed the accellerator there has been a small delay in the pick up of power. I put this down to possible slight 'turbo lag'? Also when coming off the accellerator, the engine sometimes did a slight hesitation, which could be felt through the gearstick if holding it.

However, tonight it displayed none of the above, the engine was completely smooth and didn't do any of the above, no matter how hard I tried to make it happen.

Not sure if the faulty pipe has caused me to use more fuel, however time will tell.
I usually obtain around 40-45mpg,

Looks like the turbo pipe has been 'leaking' for sometime, finally giving up the ghost on New Years Eve.

Cheers

James
Also on the motorway, the pick up is instant with no hint of

That all fits nicely. An EGR valve fault caused by it's loose feed wire melting on the very hot stainless pipework.

The melted wire causing the short, that was blowing the fuse, causing the no communication and the stuck-open EGR valve leaking boost pressure away into the exhaust and giving the turbo-lag.

Thanks for feeding back, James - pleased to hear you've got a successful result. I will check to see how my friend's Volvo is behaving.

In an earlier post, you mentioned the possibility and wisdom of spending £650+ pounds on a car worth about £2000. This is always a difficult one to call, especially if there is no guarantee that the 'fix' will work. I had a similar decision when the ABS unit on my old Mondeo was going to cost £1000+. I opted to have it done - and 5 years (nearly) later, the car's still going.

Hello Waino,

Did you ever got to the bottom of this problem? I seem to experiencing the same issue. Its been ongoing for a year now. Volvo garage telling me to change the particle filter, Not convinced that that is the problem. Elswere I found a few people hinting a relationship with dodgy connections to head lights or replacing headlights with non compatible ones.

Always use headlights when driving, will try a period with them being switched off.
