#22 of 41 99 v70xcawd - loud rotational clanking - comes and goes...
Apr 20, 2008 (8:48 am)
1. very loud clanking / rotational (speeds up / slows down)
2. there for 2-3 days, then gone for a few days
3. dealer inspected twice - "nothing wrong" - didn't do noise when there
4. jacked up - looked at anything "hitting" something - no shiney metal anywhere... - when was making the noise - i jacked up car and turned tires - but no noise when wheels turned by hand...
5. willing to get fixed - no one knows what to fix...
6. going nuts
dealer "thinks" driveshaft. not willing to shell out $&&& until sure.
any new ideas?
#23 of 41 2000 XC70 internal backfire issues
Jun 25, 2008 (8:35 am)
Hi everyone, I hate to announce that I am a new member to this forum.
Not sure if this problem has been posted before, I appologize if it has.
Sorry for the long post, but want to give proper history of the problem.
We have a 2000 that we bought 3yrs ago. Up until now no issues other than regular maintenance.
A month ago my wife was driving when she heard a load noise, a few minutes later the car came to a halt, and when she tried starting it again, it ran really rough.
Her gas tank was nearly empty as the computer indicated 16km until empty.
I assumed she had run out of gas and added a few gallons. The car ran for about 10 minutes and died again.
Got it told to a dealer, not Volvo as the nearest dealer is 4 hrs away.
Here is a list of diagnostic and work completed.
- intake was blown off, reinstalled
- temperature guage was blown off, reinstalled
- replaced coils and plugs,
- oil had accumulated around the plug openings and had started to cake, cleaned.
$600 later, I picked up the car and drove it to the store about 5 miles away. Car ran very good.
Got back in, car would not run, would start and then sputter and stop.
Left the car there overnight and returned the next morning.
Car started and ran well, brought it back to the garage.
Wanting to make sure it ran ok the mechanic kept it for 2 weeks, driving it every day for a few miles, no issues.
Last week he took it our for a long drive for about 50 miles and the car ran great.
The next morning they had to move the car, they heard a load pop and again the intake was blown off.
He figures it's an internal backfire that is causing the problem. Engine code came back as low internal pressure. He also stated that I had the turbo model,
(as far as I knew it wasn't, no turbo tag anywhere) and that it may be a turbo issue.
Before I haul this thing 4 hrs to a dealer, any one out there had the same issues and might know what the problem is???
I appreciate any help I can get.

Hi There, My 04 XC70 is in the shop as I type this. I am getting the same sputtering issue very intermittent. I took the car to an Independant not the dealer and they told me it is most likely a speed sensor or RPM sensor. I also have a starting issue but that is not related. I guess we'll see if that is the issue when I get it out of the shop. My shop has an old factory trained tech and they use all of the up to date computers to check things out. I have never had anything blown off of the engine. Sepposedly the dealer replaced the TCM when under warranty....but my guy thinks it was a security ring issue.....shuts the car down if it doesn't read the chips from the keys properly. Leave it to a dealer it replace things they don't need to while under warranty.......happened subsequent time afterward...which tells they did it wrong.

#27 of 41 EGR Valve?
Aug 12, 2008 (7:33 am)
I have a 2001 Volvo XC70. I have an "Emissions System Service Required" message on my dashboard. I read a little and I thought I needed to replace my EGR valve. The more I look around I wonder if my car even has an EGR valve.
1) When the car is warm, at idle the engine bucks and misfires. On acceleration the engine bogs down and stops accelerating unless you back way off on the throttle. Very limited acceleration. No chance of ever getting the turbo to kick in.
2) If I put my foot to the floor on the highway the engine immediately goes into reduced performance mode. I know there's a recall on that but I don't think the 2 problems are related.
Any clues on the emissions message and EGR valve?
#29 of 41 2001 xc grabs /hesitates low speeds
Nov 23, 2008 (8:24 am)
Unsure what to attribute this to..
the sensation is that the car grabs/slips as when your bicycle chain starts to derail.
occurs only going forward not in reverse
speeds under 30 mph;
as i accelerate or slow down.
happened , 11/18/08, as i was looking for parking space at the university; therefore, i was going maybe 10 mph..
also: perhaps separate issues At times, i've heard a clanking sound.
Comments , thoughts appreciated.

It's on a 2004 V-70, and subject nuisance is quite intermittent. We've just had the dealer install the control module software, so it's up to spec that-wise.
But I see that others here (dpost7?) have approximately similar issues, and I wonder if you ever got any fixes. Thanks all,

Well, We have a many issues realeting to the TCM Transmission control module and the ECM. I think both ohave been replaced twice and 3 time respectively. The control module issue are really hard to deal as at time I don;t think thye kow whats's wrong. They just start to replace parts and see if it corrects. Anyway, good luck.
