2005 Volvo S40 Q&A
2005 Volvo S40 Question: computer
My 05 s-40 had problems in the very beginning with the radio and each time they would do a software upgrade. Years later small little problems have occurred such as the temp. gage not accurate the seat sensor not reading someone seating. Now the car just wont turn on took it to a mechanic he said it's the computer. Does anyone know how much the normally runs to fix? - 2005leadfoot
What is wrong with the computer? That is way too vague. These Volvos had some problems with the coolant temp sensors and gauges, but there is an update kit that was really not a big deal.

Unless you have unlimited money to spend. - dandd
