ODB-II alarm on steady light display

After Market alarms are always full of issues especially when the batteries are disconnected of the car batteries are disconnected.

Find a Viper Alarms installer and take it in for reprogramming with their pro grade scan tool computer.

You must connect an ODB-II code reader to determine what codes are stored (which will also indicate what has failed in your car that caused the Check Engine light to illuminate). Once you have repaired the defects, the ODB-II code reader may be used to reset the stored code condition.

Probably the first and best next step wold be to have an ODB II diagnostic readout of all engine and transmission, (because engine radiator cools its fluid) alarms to help determine if you have a real issue or just a faulty sensor. Most other paths without this data would be a shot in the dark.

VW rabbit 2007 has electronic power steering so you have to send it for diagnostic testing on an ODB II tester. It is the only way you going to pick up that intermittent fault. The error code on the diagnostic tester will reveal what is causing the problem. But go check out http://volkswagen-polo-highline.blogspot.com/ to see how this gets done.

I think you need to post a little more information for someone to be of help. Cam Position Sensor and Crank Position Sensor problems are not uncommon on these cars (although you see more Crank Position Sensors go than Cam). Replacing them is not too difficult, if you have some mechanical skill. Just make sure your problem really is with the sensor before you start replacing parts. The sensors cost between $60 and $175 (depending on which and where you purchase it). If you have a specific code that you pulled from an ODB II reader, then start with that. If your check engine light is on, but you don't have an ODB II reader, then try your local parts store. Most will read codes for free.

Check engine is a generic "alarm" light. To read, a OBD II hand held computer has to be used.

1) take to mechanic
2) find oil change place that will read it for free
3) buy ODB II for about $100 at autoparts store (also Harbor Freight)

if you can find the plug m8 yes usually in drivers foot well behind dash or unders ashtray or panel under handbrake

open fuel cap, turn on key listen for whirling sound if so pump is working

Best to rent a scanner and check for other problems. If ok, the scanner will clear the light. If you bought a vented cap, the trouble will remain until a sealed cap is installed.
