EPC/Check Engine lights are on, engine won't start, radio and interior lights work, keyless entry doesn't work to open locks

did you get a tranyfluid flush ? if your fluid was the issue its more then likely need replacing. as for the engine light have your car scaned for codes and go from there. it more then likely is a bad battery or a fault in the security system happens from time to time. try unpluging the battery after you get the codes for 15 -30 minutes see if that fixes the problem.

how to turn off check engine light on 2002 VW eurovan

you repair the problem or it jsut comes back on again.

One way to get rid of the CEL is to buy a $50 scanner from Amazon. That's what I did, and everytime the light comes on I hook up the scanner. It does an analysis and spits out a code that you enter on google and voila! it will tell you what the problems is then erase and Shazaam! out goes the CEL and your stress level. Though it would be a good idea to get it fixed. The solace comes in knowing the problem and telling the mechanic what to do without being gorged. IF the CEL starts rapidly flashing..Pull over. I have been doing this for years on my cars.do on my VW Eurovan and older prius

I have an 02 winnebago vista based on the eurovan, the EPC light came on after replacing the aux battery and won't let it start now. I'll try disconnecting the van battery and see if that resets things. it ran fine before I replaced the aux battery.
