Web my 2002 jettas check engine light is on and when i scanned it it reads ''internal module checksum error what does this mean and how do i fix it? Web the check engine light (cel) on your volkswagen ( jetta, passat, golf, tiguan, etc.) can come on for many reasons, including defective mass airflow sensor, bad thermostat, engine temperature sensor, short in main wire harness, vacuum leak, worn spark plugs, and failed ignition coils. This has made diagnostics a real problem.
Check Engine Light Comes On After It Starts.
He cleared the light, and my boyfriend (who knows a lot about gasoline cars, but not so much about diesel), tried testing with an ohm meter (not sure he tested right) all my glow plugs. This has made diagnostics a real problem. So now what and how much is this gonna cost me on top of $4 a gallon for gas!

I have reset the code several times but it comes back in a day or so. It comes on and goes off with no real pattern. Are you fixing your jetta yourself?
I Changed The Plugs And All The Ignition Coils.
The code says it''s either a vacume hose or o2 sensor. Could this be a harness or relay issue? If you don't fix the underlying problem, it will either not be possible to reset the code, or it will reset temporarily but come back as soon as the fault gets detected again.
It Has Had The Egr, Egr Cool Down Tube And Intake Manifold Cleaned, Turbo Replaced, Fuel And Air Filter Replaced.
Web you can not turn off the mil (aka check engine light) without first actually fixing the underlying problem.
