Volvo S70 Maintenance and Repair
Hi, my emission light has been on steady for approx 6 months now. The code that I have is PO455 (large evaporative emission leak). Replace gas cap with a new Volvo one but no luck, car runs great (5cyl. naturally aspirated w/ 128,000 miles).
Any help would be great!
Thanks Nelson

I bought a 98' S70 T5 Volvo a little over a year ago. Loved it madly. Put 20K on it since and had no major problems. Recently, when it got colder (just around freezing t)I noticed a white creamy stuff building up in the oil dip stick tube which I thought could be just a moisture condensation from the air. I did not see anything in the oil when changing it.I never saw anything like that on the oil cap (which is a bad sign) so I did not bother until today when I noticed some white
cream on the oil cap too. I guess my cylinder head gasket is leaking. Does anybody know how frequent those problems are in Turbo S70s and
how much would it cost to replace the gasket?
Any useful advices in this regard? Why would the gasket go bad? Could it be that the engine head is cracked if the engine got overheated in the past (I would not know the history). Is there a way to tell before opening up? Compression test etc? Importantly if I do replace it would I be able to drive this car for years or it will go bad again soon? I had this bad experience with Audi 5000S ('83)in the past so I am scared...
Many thanks, folks.
Someone mentioned a sensor in the rear section. Is this easy to locate? Is it easy to change?
Another thing....when the brake light is on and I am accelerating from start, the car acts sluggish -almost like the brakes are engaged and preventing normal acceleration. Any ideas?
Good luck,
Ron
Thanks for your input, however I did erase the code (after I installed the new dealer gas cap) already, and it came back again. Anymore suggestions?
Thanks Nelson
I have a 1999 S70 and my brake light, and up arrow light come on and I have all the same problems you have described - the speedometer drops to zero, the computer only has dashes and the acceleration changes - sometimes it's much worse that others. Mine now happens all day long
The dealership connected it tot he computer and said I needed some patch and it fixed it for about 2 hours, but it has come back. The dealership thinks it might be the ABS sensor which is a $1200 part. I honestly have not gone back.
any ideas?
have checked wiring to o2 sensor up to connector on transmission - all ok ...visually inspected wiring to computer - does not appear to be any damage
and ideas??
thanks !!
100000 miles it is still within the 30 days could this be the head gasket?

New battery last week from Advanced Auto Parts. Last one purchased three years ago.
Car wouldn't start this morning (lights went on but needed jump). I drove back to AAP and they switched out the battery for another new one but noticed a mild spark when reinstalling it. He questioned if there might be short that is draining the battery.
The car did hesitate a tiny bit when turning on this past week. Symptom of battery or alternator or electrical?
If this is the problem, bypass the dealer and do the repair yourself for about $100. Rebuilt ABS modules are available for much less, and they are usually rebuilt better than the new units (new units have NOT been changed and they will still break down!)
Check out more info at these websites:

Vic Rocha (second site above) will rebuild your ABS brake module for $125 with a 5-year waranty, but you have to remove the unit, ship it to him and install the rebuilt part. It is not that difficult - my 17 year old son did it in about an hour. (It is possible, although not recommended, to drive the car while the ABS control module is off the car. See the websites above for more info.
You can also order remanufactured units from several places such as:
http://www.modulemaster.com ($110 + shipping / 5 year warranty)
http://www.bba-reman.com ($99 + shipping / limited lifetime warranty).
Both usually have rebuilt units available and can ship it out same or next day. You must return your faulty unit to them, since they will remanufacture it for resale. I have experience with BBA-reman and totally satisfied, but have talked to ModuleMaster and beleive that they are also OK. (I only chose BBA-reman because they were closer, so I was able to receive the unit faster with lower shipping costs!)
Note that Volvo used several different ABS modules, even on the same make and model car, so you will need to get the part numbers off of the unit on your car in order to make certain that you are ordering the right part. I used a mirror and flashlight and read it (backwards!) before I removed the unit.
Find a Torx E-5 socket to do the removal. They are hard to find, but using a 4mm socket (which is close to the same size) risks damage to the bolt head.
My husband has just taken apart the head, replaced 12 intake valves, replaced all 24 seals, had the cylinders machined, and put everything back together. He lined everything up, tried to start it, and nothing. There is no complression, but befiore thsi goes in for the really pricey mechanigc job I am expecting, is there anything else he can try?

Any ideas? the vehicle has 63,000miles.
thanks!
If you are experiencing speedometer lose and SRS light, ABS and Brake light is on and also from time to time you experience the cruise control not to work and then come back to life, KNOW FOR SURE THAT IS YOUR ABS Module that's not working you have to fix it. HOW?
ANSWER: go to www.modulemaster.com
they will fix any kind of module for 100$.
IT IS TRUSTED SITE. its not a scam, its just a good deal thats all.
instead of paying $700-$1000 for a new module, you only pay $100 plus shipping both way. they will also tell you how to locate it and take it off.
Many thanks!
Do you have same thing? if not what do you have??
