I have a 2000 S40 with 115,000 miles. Today while driving the check engine light came on and the up arrow started flasing. Owner's manual says this is a problem in the automatic gear box. The car is now stuck in winter mode (starts in 3rd gear). Is anyone familiar with this problem? Any thoughts would be appreciated.
You need to go somewhere to get the code. This will tell you the reason that the light is on. Unfortunately, this may require a trip to the dealer, although a good independent Volvo specialist should have a tool capable of reading transmission codes.
I had a similar problem w/ my 2001 S40. It turned out that the mode switch was sticky from having soft drinks dripped on it. On the '01, the cup holder is directly above the transmission mode switch and it didn't take much to get it gooped up. The dealer just cleaned the switch and replaced it - no problems since.
