I am getting the A1 2-3-2 code, and I understand that a dirty speed sensor may be to blame. My speedo either goes dead or erratic, and the car shifts wildy, in and out of gear and sometimes it just goes in nuetral for a few seconds while driving, and then engages again, but still erratic. Does anyone have an idea where detailed instructions are to check and clean that sensor? Also, if any one has some advice to offer as to what this might mean I would appreciate your input. I just bought this 850 non-turbo automatic with 212kmi and I have no knowledge yet about these cars. I drove it home 300+ trouble free miles and then..... I got the 2-2-2(s2 solenoid ?) along with the 2-3-2 code, but after reading and clearing those codes and 1 trouble free day of flawless driving the 2-3-2 is back with the mentioned problems. Thanks for your help!

p.s. also getting the A3 3-1-2 code , does that mean the ABS unit needs replacing?

Did you get an answer on your speed sensor. I'm trying to find out where it is located.

The speed sensor is located on the rear of the transmission, behind the right hand drive shaft.
