Volvo XC70 Engine Problems



  • dpost7dpost7 Posts: 3
    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.

    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?
  • 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.

  • 2001 Volvo XC with 157,500 miles: "Slaming in Gear" at low gears from a dead stop to acceleration (ie. if at stop sign then accelerate.)

    has anyone experienced this.. recommended solutions?

    It seems unacceptable for this to occur . any thoughts on whether this is a premature issue and therefore a case for Volvo North America.

    Friday, 12/12/08 Volvo dealership mechanic took car for 45 minute drive in residential neighborhoods described it as
    Service Report:

    1. slamming in Gear

    " internal problem, valve body in transmission, most likely in bands and clutch plates."

    1. Lower Torque mount:" found soft torque mount causing jerking during up shift and braking replace torque mount"
    2. Turbo Return lines: leaking fluid : replace turbo return line seals.
    3. Crankshaft seal, rear main : replaced at time of transmission replacement mainly due to age.
    4. Transmission oil cooler lines : replace

    also experience a banging sensation when the slamming occurs

    thank you for your time in responding
    vicki :cry:
  • Oh what an adventure this problem has been. For two years I have complained to the dealer that this car will "bang into gear" normally associated with low speed driving and shifting between 1-2-3 gears either up or down. This condition was really noticable in hot stop and go bumper to bumper interstate driving. No codes ever showed up for a long time------then Service Transmission Soon message showed up with the computer defalting to "dumb or safe mode". Volvo service changed transmission fluid looked burnt and metal flakes(bad, bad, bad). Volvo service manager drove it for a weekend and it didn't happen again that weekend. Few weeks later same warning came on. Being a bit frustrated with Volvo Dealer service I went to AAMCO. AAMCO rebuilt transmission------including valve package and a section of transmission housing that houses a bearing assembly. So far $4000 bill. Was better but still acting up. Back and forth to AAMCO but no codes. Then same issue of banging very pronounced, withj slipping and banging. Code again "Service Transmission Soon"-----AAMCO reviewed computer codes---said there were lots of codes. Replaced control module-----funny, Volvo had one on the shelf ready to go! Now it is back to brand new drivability and acts like it did on day one as a new car.

    Impressions: 2001 was a bad year---this model transmission is not in subsequnt model years. Lots of postings about this transmission, well known to AAMCO techs (not a good sign)

    Gut Feeling: Volvo really goofed this one up. Undersized transmission for relatively heavy car. To improve performance it made the transmission run at higher pressures than it could handle and slowly tears itself up! How come no fess up by Volvo---gave up on transmission in next model year!
  • i disagree, i drive an 01 volvo xc70 and it is great
    smooth ride
    lots of torque considering its small engine
    turbo works well, accelarates great considering its weight
    decent mpg
  • lol ok how many miles on your magical 2001
    thanx J-R

    so it sounds like what is being described is my problem exactly....I have a 2001 XC, now with 202K miles on it...and it's behaving as everyone above indicates...I just dropped 4K to have the front end rebuilt....all needed, check engine light is now off...but the performance is dropping like a stone...and it still does the slam into gear and hates, hates stop and go city traffic...

    I am afraid the only option is to rebuild the tranny...any thoughts????

    well after having my car at my mechanic .....i told them that the issue only happened when the temp of the engine was cold...which we all know only lasts for a couple of works great until it reaches its full boil...which is only minutes after cold....but like i have said before my issues are not all the time when the engine is at full boil my mechanic has said i should take it for the software update ....which i will ....after paying for the ....but i love my car ...i really do ....foreal
  • Purchased this car one year ago today. Timing belt was replaced before we picked it up. The car only had 102,000 miles on it at that time. We have made numerous repairs on the car, but still liked the ride. In Dec. 2010 the check engine light came on with a P1332 code. Did some research and had the CVVT solenoid replaced. Also, put new brakes and tires on. About $1500 for all of this. Did all the work the week of Christmas. Last Sunday, while driving on the highway the car lost all power, coasted to what seemed like the safest spot to stop. My husband looked under the hood and saw that the springs holding the timing belt let go. Now I'm told by my repair person that it's not good and we're looking at $2500 to $3000 in repairs. His advice is to get rid of it, but we don't have the money for a different car.

    One of my questions is, do you think when the solenoid was replaced could that have caused the tension spring problem? Also, opinon on fixing the vehicle, we have so much into it all ready. It's a beatiful car otherwise.

    I've had all of the transmission issues mentioned in previous posts. I bought the car with 100k miles. It was shifting very poorly, slamming and slipping in 3rd and down shifts were like getting hit with a sledge hammer. I flushed the fluid, it would be OK for a while and then return to the same thing. I changed the fluid a few times and the same thing kept happening. Changed the B4 servo, no impact. I bit the bullet and changed the valve body, 1100$ later it shifted good for about 2 weeks, fluid was dirty again. I gave up on trying to fix the transmission. One day I decided to change all the fluids, I drained the coolant, color seemed a bit off but not too alarming. About an hr later I noticed little red dots showing up on the surface of the old coolant...A light went on in my head, so I went to nappa and got myself an auxiliary trans fluid cooler and bypassed the rad completely. Changed the trans fluid again. Went to the dealer to not just reset the adaptation, but to completely reload the software and do the adaptation procedure. While I was changing the oil I noticed that both my upper engine mount and the lower torque mount were shot. I replaced them both myself in 30min. It's been 2 months and my trans fluid is still cranberry juice red and its still shifting great. So if you've changed the trans or valve body or fluid and it runs good for a bit and then goes back to poor behaviour it's most likely leaking coolant into the oil through the rad. Either bypass the rad for 100$ or get a new rad for 300$. In these transmissions since they are almost a constantly variable slip oil chemistry is very important, you don't need 5l of coolant to leak in there. Even an ounce can change how it shifts tremendously. And you won't notice an ounce in your 8L of coolant nor in your 7.4L of trans fluid but your transmission will.

    I don't have any springs on mine, just a tensioner. Sounds like whoever installed your timing belt didn't do it properly and the timing went off or he set the tensioner too tight and it ate your belt. Either way you need a new head assembly. You can find one at a salvage yard for 100$ and get it replaced with a new gasket for another 500$. You are also going to need a new belt and tensioner. Get someone who knows what they are doing to install I though.
