I have previously posted a problem with my daughters 92 960 wagon ( 165k ) regarding a strange involuntary change from economy to winter mode while driving under normal conditions. This is usually accompanied by a continuous flashing of the mode light. She had the PMP switch ( replaced 2 yrs ago) checked out on diagnostics but that was "OK". Other diagnostic codes that did indicate error are:

Code 222 Solenoid " 2 operating circuit
Code 113 ( control unit ? )
Code 122 Solenoid " 1)

According to the tech - they have never needed to replace a code 113 control unit. Tech says it must be the solenoid " 2 ( inside the tranny ?) which is a major deal, probably not worth the money although the car is in otherwise excellent body / engine condition.

My concern is the tech ( Volvo specialist ?) does not seem to know exactly what the cause of the problem is and is guessing that you can try the chip first ( $ 350 ) but if that isn't it - then replace the tranny !!!

Why not just eliminate the mode process - she drives in the economy mode anyway. Is this possible as an easy fix ? how ?

"V70" are you out there - your thoughts were the PMP switch, but this tech says diagnostics do not agree. Any thoughts ?

My 1993 965 does the same thing, sort of. Mine will upon startup, not start and the arrow flashes and the lights on the S, W, E flash at the same time. The car must sit,sometimes as little as a minute, other times as long as ten minutes. It will then start and the lights will flash for the next several events, short drives. The transmission during the flashing is NOT in winter mode and the car drives normally.

This has happened about 5 or 6 times in the last month an a half and may be happening more often now.

It happened to me last weekend in a parking lot and on the second try I jabbed the accelerator once sharply and it fired. My wife tried that tonight with no luck so she let the car sit and came back in an hour and a half and it started right up with the lights flashing.

Volvo Dealer ran the codes on the flashing Trans fault with arrows flashing. Result; bad battery terminals were causing several faults compounded by a "throttle Position sensor" code indicating that component was bad. Less than $300.00 later the car is fixed.

WRONG

One week later, same thing. So much for the "codes". Back to the dealer on the 22nd.

These have a lot of problems with this flashing. Usually a transmission fluid change and some transmedic and the lights will go out. Otherwise a rebuilt transmission. You may ned a couple of changes or a flush.

I have a 1992 960 Wagon, too. Just turned over 100,000 miles. At about 85k
the W and E shifter lights started the "disco lighting" effect.

Follow up with a read on "960/90 Fluid Flush"

The results were extraordinary.
