#27 of 34 EGR Valve? by jgb2000 Aug 12, 2008 (6:33 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.   Symptoms: 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 34 2001 xc grabs /hesitates low speeds by goldrich Nov 23, 2008 (7:24 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,   AS Replies to this message: dpost7 (Dec 11, 2008 1:51 pm) goldrich (Dec 14, 2008 7:17 am) JoeBags (Dec 16, 2008 5:50 am) nikosgrfan (Oct 27, 2009 1:09 pm)

Replying to: ashore1 (Dec 11, 2008 12:59 pm) 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.   dpost7

Replying to: ashore1 (Dec 11, 2008 12:59 pm) 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 Replies to this message: JoeBags (Dec 16, 2008 5:50 am) nikosgrfan (Oct 27, 2009 1:09 pm)

Replying to: goldrich (Dec 14, 2008 7:17 am) 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!

Replying to: JoeBags (Dec 16, 2008 5:50 am) i disagree, i drive an 01 volvo xc70 and it is great comfortable smooth ride lots of torque considering its small engine turbo works well, accelarates great considering its weight decent mpg
