V50 Engine 2.0D : Lots of fault messages

[adye]

55 plate V50 2.0D. 105,000 miles
Car broke down 5 months ago and ended up at Volvo main dealers.
Dash warning messages :
Anti Skid service required
Brake failure. Stop safely
Engine system service required
Wipers came on on their own. Car just went to tickover, would not rev and crawled to side of road.
Main dealer cleared loads of fault codes ,could not find any particular problem, downloaded latest software and away we went !
Didn't really fill me full of confidence !!
In the mean time the car has generally been ok but occasionally runs a bit lumpy and on one occasion would not rev beyond 2500rpm.
Now broken down again ,exactly same as before. been recovered to main dealers again.
Could it be something simple like a battery fault or bad earth ?
Any thoughts gratefully received.

Typical symptom of a faulty CEM.

Yip, unfortunately it is typical symptoms of a faulty CEM. This will cost about £600 at the Dealers.

Thanks for the advice and prompt replies.
Will be speaking to the dealers tomorrow.

If it does turn out to need a new CEM then have a serious word with the dealer about being re-imbursed for the previous visit - it is obviously the same problem??

If is CEM issue let me know can end up with much lower bill...

I had exactly the same messages coming up and the car behaved in exactly the same way (same model and year of car) and I have just had the CEM changed (over £700!) and it seems to have cured the problems. Time will tell!

remove the air filter assy , check the whole engine bay loom everywhere for rubbing around the gearbox area AND on the sharp AC Pipe crimps behind the right hand headlamp , also in the same area the loom runs over the sharp chassis edge .
if you push and pull the loom to move it , even if te CAN network is earthing out , the fact you have moved it could well cure it for the rest of the cars life .

I have had almost exactly the same fault and set of warning messages. I was just starting on a journey and suddenly the car gave the "brake failure - stop safely" message and stopped responding to the accelerator. Other strange collections of failure messages arrived afterwards including a spell where the steering lock would not respond to the key. AA could not find what was wrong - they did not even attempt to look into the ECU - I think they have seen this many times and knew it to be a waste of time. My local man had to send the car to the main agent in Gloucester. Johnsons believe that the problem was poor contacts into the ECU as they could read codes but not communicate with the ECU otherwise. The car has been fine for several hundred miles since.

However, I have no confidence that it will not happen again and, on thinking about it, had this occurred travelling down the centre lane of a busy M5 at 70mph (outside lane averages 15 mph faster!) I could have caused a pile up and injured others or myself or worse.

To me the engineering in this car is unacceptable. I have driven the car only 13500 miles since I bought it. In that time it has had a DPF sensor failure that put the car in a dangerous position whilst overtaking an articulated lorry, the 150amp alternator blew a rectifier diode at 77000 miles, the above problem happened, and now I have a knocking antiroll bar tie rod ball joint. The failure rate is so poor that it has to go in the bin - the most fragile undurable and most dangerous car I have ever owned. If you transferred the failure rate to an airliner jet engine each engine would have about 25 serious failures in a nornal service interval.

Hopefully my next post will be saying goodbye to the forum and anything Volvo.

The exact same thing happened to my 2005 2.0D V50, had it tested at garage , nothing found on diagnostic, runs lumpy too. did you get to the bottom of thid problem? bob
