I have a 2004 S40 2.4Ltr Auto LE sedan Volvo Automatic and I am having a few issues with it. The car has developed a nasty vibration through the vehicle at 2000 - 2200 rev's. It is also under acceleration while turning right making a noise as if it is poping from the right front corner. When I go over bumps or pot holes at any speed the front end makes an extremelly loud knock - actually sounds very rubbery to discribe. The car while driving feels un even in the front. When you go over undulations or bumps I notice the vehicle listing - not sitting evenly on the road. I have noticed these issue's devolpe quite rapidly over the past 2 - 4 months.
Check the right side engine mount. The hydraulic fluid leaks out when bad and causes the engine mount to collapse and the engine to actually sit on the frame. As you turn the vibration gets even worse. Also inspect the lower torque rod mount for any debri like rocks? They can cause a vibration as well. As for the rubbery noise while going over bumps, you will need to replace the bump stops on the struts (See #1 on image belowe). Volvo has actually came out with an updated bump stop for it P/N 30760405. When replacing I would recommend you also apply some grease. To verify it is the bump stops you can actually lift the dust boot up with the wheel off for better access. You will see the bumper should already look almost yellowish now but it is white. Spray some penetrating oil in there. The noise should go away for a while but will soon return. If the struts are leaking, you may as well replace those as well with bump stop. Who ever does the job needs to be carefull with the bearing. That falls apart really easy and the bearings will all fly off. Learned that the hard way my first time GRRRRR! So you may want to replace that as well? For the vehicle sitting unevenly it comes back down to the strut again? Are they leaking? Also inspect the coil for any damage like cracks? Well good luck and hope this info helps you out?

Good Morning JIS001,
Thank you for your reply. I will check the list of things you have advised it could be. Yesterday I jacked the car up and removed the front wheels - looking for any wettness (oil marks) or excessive play in joints. To my surprise it was dry and I couldn't get any movement (besides the appropriate) movement from the joints. However I did get side ways movement from the lower control arm bush (which in Australia is not serviced seperately - you have to buy the entire control arm - frustraing and expensizve. This doesnt explain alot of the issue's this car is having though. Another problem developed yesterday as well - the protective cover in the gear shifter area shattered - broke and now the vehicle can not select M+ or M- (I have had enough of this car). I used to be a loyal Volvo owner - but after in the last two years these issues - Replace VVTI Control Mmodule, all belts, puley's, Oiul Trap, Fuel pressure sensor, Vaccum pump, PCV valve, oxygen sensors x 2 (front and rear) two times, extremely bad fuel economy - I have had enough and plan to get rid of this car immediately.
But thank you once again for your help - it is much appreciated.

Wow sorry to hear you have been having some problems with your vehicle? Did you remove the platic cover? If you have not you can have other problems as well like not being able to put it in drive or park if it blocks the gear selector? Also what kind of fuel are you using? If you are using the low grade I would recommend using premium especially if you have a turbo? Low grade fuel usually has too much ethanol and causes all kinds of problems. Something to think about? And yes the lower control arms need to be replaced once the rear bushings split or you have a bad ball joint? You may want to look for aftermarket parts? Also next time there are oxygen sensor codes, check the fuse first. When the vacuum pump shorts out it blows the fuse and that circuit is all tied in together. As for the oil trap, you may want to see if you had some kind of extended warranty on it? If you paid for it see if you can get your money back? So look into it? I guess each state and country may have it's own emissions warranty but usually partial zero emmisions vehicles have a 10 year 150k mile warranty on some of there emmisions components. The oil trap box just may be one of them? Contact Volvo. There contact info is usually in the owners manual.

I have Alan Deesel's number and the rest of the Volvo "heads of State" contacts here in Australia. Volvo came to the party with "good will" on the VVTI control module dying, which was nice of them (as there seems to be a fault with the oil trap failling and then causing the VVTI control module to dye - the stock Volvo keeps suggest's it's an issue) however they will never admit that. I had the oxygen sensors replaced at a Volvo workshop the first time - only to on the way home have the emissions light come back on. They charged me $1500 per sensor, ($3000 including labor) only to have the light continue to come on. They couldn't work out what was wrong with it. Yup I know. Anyway took it to another dealer who within 5 minutes picked up it was a fuse - so they changed it for me. Well the fuse blew a week later - so replaced the sensor's again. Problem solved - noooo, the fuse blew again, so I took it to another dealers workshop who were actually clued up on these cars - he said it was the vaccum pump (like what you have had said) and evidently it is a common fault. The list and stories go on - seriously. I run the car on nothing but premium unleaded (even thought the cost is wrong), I servise the car on time - but yet it one of the worst cars I have ever owned. My mother has a 2009 version - and it is having no end of issues as well. We have always been a volvo family, always however not 1 of us will purchase another one. I believe the Ford days have had to much influence on the way Volvo's are now. They have raped the name and stripped it for all the safety features - making the cars worse and I dont believe the Chinese will make it any better. It needs to be returned to its parent company AB Truck and Bus Sweden.
Have a great day - Kinds Regards

Well I hope you got a refund for the oxygen sensor repalcement since it was never fixed right the first time you took it in?
