While we were try I g to repair this vehicle we were test driving it a d came to a full stop at a stoplight signal and could not downshift vehicle into 1st gear from a stop after the vehicle was at normal running temperature. Causing it to go I to a limp home mode. So while we were driving we noticed that the floor was saturated with antifreeze and a sweet odor from the vents was noticed with a smoke . We serviced the transmission without success . Also noticed an no oil pressure read on dash only when we were not in acceleration. This disappear when upon acceleration and returned when idling. We serviced the oil filter the fluids performed a motor flush first and replaced the oil pressure switch. Without successful repairs and continue of the code returns after performing a drive cycle numerous times. We are convinced this is caused by the recall #r155. Thank you for help in repairing this issue under the NHTSA recall#06v441000.

I own an 1999 Volvo S80 (t6 turbo) several months ago the car developed a rough idle and engine surge when the rpms were below about 1200. I have had the car looked at by a Volvo dealer and independent mechanics. No one has found the problem. The error codes that are being generated are inaccurate. Replacing the indicated parts does not solve the problem. The most dangerous aspect of this problem is that when in reverse there is a significant engine surge at times. This creates a very unsafe situation because the surge is not predictable. Significantly increased pressure on the brake pedal is required to keep the car under control while in reverse when this surge occurs. I strongly urge you to investigate this defect in the Volvo S80 and take action to require a recall of these vehicles.
Transmission problems causing dangerous driving conditions. The transmission slips when going between 2nd and 3rd. Also had issues with the engine going to 700 rpms when going 65 mph. This is just one of the many problems. The solenoid went out in the transmission about 13000 miles ago. Currently I have three different error codes "transmission service urgent", low oil pressure stop engine ASAP", and "emission service required". I have read many other people have the same problems I have had. Nm.
Engine miss firing and emission light on. Later engine running good but cruise control would not work and text message 'engine system fix next service' with orange warning light on. Took to Volvo dealer and they replaced the etm for no charge. They kept the old part because they had replaced the original one.
My 1999 s-80 Volvo lost power temporarily while my wife was driving the vehicle in traffic. Several of the cars warning lights came on including the transmission service required and brake service required immediately type messages. The Volvo dealer just replace the abs module and several coil packets and spark plugs. A couple of old parts were left in the inside of the vehicle. We are not sure what the parts are.
Volvo S80 t6 1999. Defective etm (throttle module or throttle unit). This module failed at only 64,000 miles and is not covered under Volvo warranty. I understand this is happening to almosy every owner of this model year. I'm asking for Volvo to cover the replacement cost (parts and labor). The failure of this unit could cause severe injury and/or death as the vehicle engine will die at any speed and anywhere without notice. The dealership replacement cost is over $1000.
After stopping at a light or sign with foot on the brakes vehicle jumped forward several feet. Also, when trying to pass another vehicle on the highway vehicle decelerated instead of accelerating, nearly causing an accident.
Car dies without warning at high speeds and low speeds, apparently Volvo knows that there is a bad computer chip in many of the cars but does not admit to it because it costs $800 to replace the chip. I found this out from another Volvo driver!.
