Diagnosing Bad Engine Mounts

The RPM are 840 on both “N” and “D”, however when I throw it on the “N”, the sound goes away.I tried, having it on “D” and holding the brakes, to raise RPM to about 1100, and that is when the noise is most evident.The best described it is a very low intensity roar and slight vibration.

I’ve been looking for something like this for a long time. Found it. Here’s the invaluable Volvo Wheels PDF from Volvo themselves. https://images.matthewsvolvosite.com/wheels/Volvo-Wheel-Brochure.pdf Wheel Names, Alphabetized & Sizes…

Turbo S80 TCV & Vacuum Line Routing

The pressure from the outlet of the turbo presses on the wastegate diaphragm to keep it closed. When the ECU decides there is enough boost, it stops allowing the air from the turbo outlet from going to the wastegate actuator and allows it to go to the compressor inlet tube. The system is a pulse width modulated system meaning it is never “always on”, but instead cycled on for longer periods of time to increase boost, and shorter to decrease boost. When the TCV is off, air from the compressor is dumped to the compressor inlet, and the spring pressure in the wastegate is what regulates compressor outlet pressure.

S80 Transmission Rebuild In-Car DIY

I have a 2000 S80 T-6 with the same P0756 troubles everyone usually runs into, namely no shift into 3rd or 4th. Swapping the whole solenoid set had no effect, so it was time for a complete unit swap or a rebuild. As this is my project car, and I’d done a few VW transmissions before, I decided to do it myself. The idea came from watching this series of videos on YouTube, it’s possible to fix the problem our cars have without actually removing the transmission, so this rebuild just replaces all the clutches and worn bushings and the 4th gear shaft, leaving the torque converter and differential alone.

Who Repairs 2004-era S80 ABS Modules?

I have read the great 21 pages on this repair in another forum on this site. I am inspired to attempt the same repair on my 2004. Most of the posts, however, seem to pertain to slightly older model cars than mine.
