2001 V70 D5 randomly cuts out.

[andydeejay]

Hi all.

This all started after my wife left the ignition on all night and flattened the battery.

I hooked up to another car with heavy jump leads, connecting the ground lead to the chassis and the red to the positive stud by the fuse box. Tried cranking but must have had poor connection and only had enough power to engage relay. Gave leads a wiggle and tried cranking again - this time yellow engine light on dash blinked rapidly. Over the next 10 minutes, repeated several times without success until finally I must have got a really good connection and it cranked up and started ok.

Since then, driving at various speeds, engine just randomly dies and brings on yellow engine light, shuts off heater fan, disengages cruise control then comes good all within about 1 second. In order to get cruise control to work again ignition must be switched off and on again. No error codes displayed on computer. It does this maybe once a day, twice in 5 minutes or occasionally behaves ok.

Can someone help please - There are about 110,000 miles and the usual door lock problems. Have I damaged something??

Thanks

Andy

Hi I have an S60 D5 with the same problem. I bought the car in Feb and it started stalling within 2 weeks. Just cuts out with no warning sometimes on tickover sometimes at speed. Mines an auto which when it cuts out in drive leaves me with no steering or brakes. Car always restarts 1st time. anyway its been back to the dealer 3 times and had new power relay and wiring, new ignition switch still has the problem (no error codes just like yourself) as the car is dangerous the dealer has now involved volvo uk to try to find the problem, I dont know if the car has ever been jump started like yours as it is 3 years old with 125000 miles. They seem to think it is a voltage drop somewhere but cannot trace the fault as yet. I think they have had the car more than me but i want to persevere as i love the car. I'll let you know how I get on maybe, email you. Fortunately I wont have a bill as the relay itself was 500 quid even though it failed to rectify the fault. Good Luck By the way the record is 13 times in one 20 mile journey. I,m too scared to drive it as it is

Not quite so bad as your problems, but a guy i know had intermittent misfiring on his V70 D5. The local dealer had it for about 3 weeks and eventually found the problem to be a crack in the relay circuit board.

As an aside: Speaking with a vehicle technician (mechanic with a laptop) and his boss, I was told that during a recent clutch replacement the ECU may have been 'spiked' and require a full ECU reprogramming by a main dealer, when the battery was disconnected!!!!

They informed me that the correct sequence when disconnecting the battery is earth off first followed by the positive. When reconnecting, positive first then earth! This ensures that the battery isn't earthed when removing / attaching the positive lead and spiking the electronics!!

The problem turned out to be a disconnected clutch pedal sensor, which when reconnected resolved all issues I'd been having with an 'Engine Service Required' message that would not be reset and a non functioning cruise control system!!

Yea - sounds like I have "spiked" the ECU because I did put the junp leads on and off and get the odd spark on connection.

I am having some journeys without problems - some dropping out 6 times in 20 miles. When it goes wrong the rev counter goes bananas. Sometimes it looses power for 10 seconds which is a bit worrying......crossing over a busy crossroads for example. One of the times is said "major traction service required"?

Thanks for all the responses so far - I would like to go the the dealer armed!

You're supposed to have the ignition switch in a particular place when you reconnect as well, it's in the handbook.

Only this week, mine is back with the guy I bought it off. He took it to his mechanic and payed 40 quid to hook it to a Bosch computer but found no error codes. Of course the car was on it's best behaviour and didnt cut out once.

We have currently swapped cars - red astra estate! - and after a couple of days and a journey to dublin it started to cut out. He reakons it could be several things and promises me it will get fixed. It is heading over to Volvo today. At least he will have a bit more authority with the main dealer and might be able to bypass a lot of the B/S.

Hi all
there is a fault on some D5 fuse boxes under the bonnet,causing the vehicle to just cut out this doesnt sound like a ECU fault as you said the fan cuts out this seems to surgests its loosing a live feed so either relay or fuse box,just some information to be going on with.

[Engineer]

Worth a look, just sorted a similar problem and it turned out to be excessive injector leak off causing the pump to over pressurise and ECU protective shut down. :)

[steveall]

Hi all My similar problem was outline earlier. Volvo has modded my fusebox and wiring as the 3rd "FIX" still stalls so its in again, after 7 months i have had the car about 2 month total very frustrating and dangerous. Garage (non Volvo) i brought the car from are as frustrated as I am at least they give me a loan car and are now looking for another car for me. I'll keep posted as to the outcome.

I agree with John Griffiths about the fuebox loose connection.
My 2001 D5 cut out in a similar way for a split second - dropped cruise - fans cut out etc. which went on ramdomly for quite a few months, occasionally dropping into limp mode for a few miles before taking off again.
It was traced with the help of PGI in Farnham to a loose connection on the fuse box - a known fault according to Volvo on early 5's
They say the circuit board may have been affected but to date mine is fine after 3000 + miles
I have the colour codes for the cables in question, not on me at present, but will post them later in the day
Hope this helps

Ref my post of yesterday
The following info has solved the problem with my V70

TJ (may be a Volvo code)
Fuse Box Connector
Main Feed
Grey Connector
RED WIRE IS LOOSE
Terminal 7 1520
Engine Front 11B4
Remedy is to tighten connection / replace connector and or circuit board

Hope this helps

Status - Fixed


My friend who supplied the car took it on himself to get to the bottom of this problem and sort it one way or another and I am very pleased to say he had success.

After several hours of no success with the disgnostic computer and the threat of going to another volvo dealer, the dealer in Antrim did a "master Reset" to the ECU. The car has done hundreds of miles since then and hasn't had a problem since.

Hi all, My first time on here but sounds like my 02 V70 D5 SE (192K miles) has the same problem. Unfortunately Its getting worse and worse. Started cutting out every couple of weeks but now is about every 20 miles. Doesn't mater what speed I'm doing or weather using cruise control it cuts out, rev meter goes bonkers bouncing up and down and then sometimes restarts again within seconds, however the cruise control will then not re-engage untill ignition is turned of and re-started. No codes are showing down at the dealer but the problem is developing. Sometimes I get the message 'anti skid service required' and the latest fun is when it says 'start prevented'. If this message comes up I have to take the keys out the ignition then re-insert yet it starts again no problem. Having all this happen whilst overtaking on a busy motorway is not amusing. Help!

[neilfoottapping]

This sounds pretty similar to my problems. Is it worth suggesting to my dealer they look at the fusebox - does that seem to solve most peoples problems?

[neilfoottapping]

Hi Adam,

Did you manage to get yous sorted?

[Georgey dee]

Which fuse box are we talking about? Just for future reference:thumbs_up:

I can't believe it - I waggled the red wire into the fuse box and all my cutting out problems have vanished! I am so pleased to have it fixed but I have spent fortunes on so called diesel and Main Dealer experts. Thank you so much for your help, Best regards, Norman.

[Chesterman]

You kept going back - and paying more money. They sound like experts to me!

For years my 2006 V70 has suffered from cutting out without warning and will not immediately restart. After switching off completely and waiting for various clicks from the various control units (a couple of minutes) it then starts fine. This has usually occured shortly after leaving Spain and crossing into France on our twice yearly trips to Spain. I put this down to the sudden drop in temperature and humidity change causing water to release from the diesel, be sensed by the injectors and result in an engine shutdown. Yesterday I changed the left hand headlight bulb which requires the disconnection of the ECU (red plastic cam clips) to gain access to the headlight. I then had the cutting out problem big time. A spray of the ECU connectors with WD40 and everything was fine. So, yes my historic problem problem was a temperature and humidity change driven issue but causing a poor electrical connection not a fuel water content problem. I was misled by the sophisticated cam connectors thinking that they looked so over engineered they could not be a problem....so wrong!
