Volvo S70



  • Just bought a Used S70 T5 - great for a few days, have a strange loss of power, basically done a full tune up on it- Has anyone had a similar problem that may have advice ? Love the car - Want my power back tho lol!!!!

    My base model (really base, no leather or sunroof) is up to 136K now, still running well, few rattles, no burning oil and rides in many ways like a new car. My experience with my Volvo is that:

    - You'd better find a good independent repair place, the dealers charge a fortune for almost everything and often have long backups for getting service
    - Motor and transmission are solid- what drives you nuts are little electrical things like bulb replacement (frequent), radio not working well, doorlocks- and my sister's Volvo S80 had similar problems
    - Still the best seats around and a safe car that makes use of its size with roominess and logical design

    And I will run mine into the ground or until something major happens. I have taken test drives in new cars (Mazda6, Honda Accord), then I get back in my 1998 Volvo and it is still more comfortable. And you know, if you can keep driving an older car and not have to assume the massive depreciation of any new car, you are way ahead of the game!
  • My radio fades in and out also but my antena is stuck half way up I was going to replace that first. But I was wondering if anyone knows of another problem it may be for the non reception fading in and out at times?

    I, too, have the same problem re: my antenna in my '99 S70. At first it only got stuck halfway during very cold weather. But now it does that all the time. My radio reception has suffered consequently. Is there a way to lube it or something else, or is replacing the antenna the only option?

    You can completely disassemble the antenna and lube it up ... but it may have stripped teeth, so it would do no good.

    I had mine apart. If you don't know what it looks like, picture one of those toy motorcycles where you zip a toothed nylon chord through the wheel to get it revving. That's what in inside the antenna ... a very long toothed nylon strip. As the motor winds down, it curls the nylon chord into its case, retracting the antenna ... and vice versa to extend.

    When mine did the halfway thing, I took the much cheaper option of buying just the antenna with the nylon chord attached instead of a whole new assembly, which I had to disassemble my motor casing to install the new chord. It was a real pain. As you may imagine, the nylon chord does not want to stay wound and acts like a spring. So it is quite trying to wind it and keep it flat in the case while you try to put the cover back on, while your hands are covered in the lube that covers the chord.

  • I am having the same problem with my s70 for about 2 years now. After the turbo went out a couple of years ago. the car has been losing power. I have spent around $4k on this car. I have replace sensors,everything the mechanics can think of. No one can find what is wrong with it. I love the car I bought it new and just wish someone could help me to get it fixed.
  • qbrozenqbrozen Posts: 17,141
    What kind of mechanic have you been taking it to? Is it a volvo dealership? Or at least someone who specializes in volvos?
    One common problem is vacuum hoses going bad. On a turbo, this is absolutely crucial. If you still have your original vacuum lines, you may want to look into replacing those. There are entire replacement aftermarket kits you can purchase for not alot of $$ (~$200, if I recall correctly).

  • I have been taken it mostly to the Volvo dealership but I have taken it to volvo specialist as well. Is these vacuum hoses something that anyone could replace or does need to be done by a specialist and where can I get the hose other from volvo. I know volvo's would be very expensive
  • qbrozenqbrozen Posts: 17,141
    well, there is some info for you on Volvospeed.

    However, they say you should be getting a check engine light. ?

    IPD offers some cheap replacements.

    You also may want to check the hoses highlighted in this diagram. If a turbo hose becomes to soft, it can flex when driving, causing incorrect boost pressure.

    I have a 2000 S70 GLT SE with 65,000 miles on it, live in the Seattle area. Last week, I noticed that when I have the fan on (heat or a/c), the car does not keep a steady acceleration either with or without cruise control. It jerks and bucks like it's not getting enough gas, like a clogged fuel or air line, and only when the fan is running. The fan is not affected, such as slows and speeds up or cuts out, it is steady. Previous to this, the car sat for almost 3 weeks, being driven twice, each time for about a 3-mile drive. Does anyone have any thoughts as to why this might be happening? I'm thinking electrical in some way, due to the fact it's only when the fan is on. Thanks.
  • qbrozenqbrozen Posts: 17,141
    yeah, its got to be electrical. Why or how? I have NO clue. I can't see why the engine's spark would be connected to the fan's power in any way. Very strange indeed. I'd love to know what you find out.

    I have a 1999 S-70, 122,000 miles. My wife was driving it approx 10 miles a day. The car would lose power sometimes, that is would not go over about 10 mph at times. Finally, it does that all of the time now. I replaced the fuel filter by the passenger side rear wheel yesterday. The car still does the same the accelerator to the floor...the engine will not rev over 2K. The dash lights & headlights flicker slightly. When the air is turned on the red brake light & the amber ABS light come momentarily and then go out. The car idles fine with no misses or backfires etc. Any ideas?

    Could be the Mass Airflow Sensor or the Electronic Throttle Module.
    You need to take it to someone who can read the car's computer.

    I have a service appointment this week. Thanks for giving me these two specific things to ask about. I will let you know what it ends up being.
  • joshua9joshua9 Posts: 2
    I appreciate the info. I have been down the sensor path before. I want to get this car ready to sell. It is a good car, but it is time to let it go. I will let you know what the problem is.

    Thank you, again.
  • culigrillculigrill Posts: 3
    Indeed it turns out to be the Electronic Throttle Module. Interestingly enough, Volvo does have a service campaign for this issue, which is resolved at any dealer free of charge. Thank you for your help!

    Your welcome. ;)
  • hi all. my trusted '83 245 Turbo is on its last leg and am interested in buying a low-mileage S70. there doesn't seem to be a whole lot in the SF Bay Area but i did find one: an S70 AWD, Nautic Blue, 74,000 miles. Asking price: $8800. Comes with leather, CD/Cassette, Sunroof. No wood trims. haven't run a Carfax yet but seller says he bought it in Berkeley, CA. here's what he says about the car:

    *Always had it service at dealer
    *had the computer replaced in Oct- paid $1400 (would that be the ETC?)
    *thermostat was replaced
    *timing belt changed a few years ago
    *Replaced with new Firestone tires
    *never in accident but has minor dings and scrapes

    will be test driving it soon. price seems high. not sure how low to negotiate to. Edmunds TMV is $7200.

    after reading the first 30 pages of this thread, i've noticed many have had problems with ETC, among other things. and some have advised against '98-99 models. anything to be worried about this model?

    i will use it primarily for commuting to work (20 miles daily) and local trips. doubt i'll ever drive it to snowy Tahoe, so AWD isn't a necessity, but will come in handy during bad rainy season i guess.

    i will definitely have it inspected at mechanics and look at service records but not sure what to look for and what questions to ask, since i've never bought a car before, esp. used. any advice is greatly appreciated!
  • volvomaxvolvomax Posts: 5,274
    I would have a Volvo dealer or qualifed Volvo independent shop do a buyers inspection.
    There is nothing inherently wrong w/ the 99 S70.
    Make sure the service records are up to date
  • 1) Two week ago, engine starting running really rough while driving and while idling, this was after running errands for an hour or so, with no problems. Seemed like it was going to stop dead any minute. Took it into the shop, they said it was a bad coil. Replaced it and also replaced all spark plugs.
    2) Drove off from the shop and within 3 miles, it started doing the same thing again.
    3) Took it back into the shop, one of the spark plugs was bad, replaced all of the spark plugs again (both times using Volvo spark plugs.)
    4) Drove fine for about 30 miles, started doing the same thing again.
    Instead of my favorite local volvo shop, this time took it to the dealer.
    5) Dealer is saying diagnostics show misfires on all 5 coils, plus oil leaking on the timing belt and another oil leak on the rear cam.
    I understand that once a coil goes bad, it is not long thereafter that the others will go, very pricey to replace, however, I just had one of the coils replaced, why would there be 5 misfires should only be four at this point. Also, would the oil leak on the timing belt cause the feeling of the misfiring... (which I am not sure about either, as there is no oil drips under the vehicle, when parked or idling)

    I have no idea what I should fix and what is not necessary. I have already put in some big bucks to get this far, with no change in the engine at all.

    Any suggestions would be appreciated.
