    On 2002 jetta's there's a TSB about the spark plug coil pak ground. They develop a bad ground and a new ground must be run. I'd need to know the code's it's showing to fix.

That happens sometimes dont worry. As long as the light isnt blinking it is fine. Just drive it for a few days. If it doesnt clear itself, take it to a shop and have then clear it for free or cheap. You could also disconnect your battery for 15 minutes or so and it will reset the computer and whipe the check engine light off. Sometimes if you have a bad plug or all cyclinders arent firing it causes the check engine light to come on. now that everything is replaced just do what I said above.

hi if your talking about service then you need to find out when the timing belt was done last if it has not been done then its due.

other than that you need to check gearbox oil level

check tyres and tyre pressure
check lights working
check washer bottle fluid level and check its working
take it for a drive on a bumpy road and listen for any knocking noises if any are heard then bottom ball joint needs replacing.

Changed oil and spark plugs in my 2000 volkswagon jetta and now the check engine light is on any ideas why its on


I don't believe the oil change would cause the problem. The only thing I can think of that would cause the engine light to be ON is maybe the spark plug gap isn't correct. That may cause delay or pre-firing the fuel in the cylinder.


But, there are many emission sensors in the car that will make the engine light come ON. Not to mention the big list of trouble codes for the engine light. The engine light code will give you a big clue of what's causing the problem.



Best way to find out what's going on engine light is to have an auto-parts store hook up a engine code reader and tell you what the code means and the problem. Most auto-part store will do this for free.
If you get a codes like P0300, P0301, P0302, and etc. Then the spark plugs need to be look into.

My epc light went on in my 2002 volkswagen jetta


Take it to the dealer, the EPC warning light - and even more the failsafe run which doesn't allow you drive faster than 20mph) is an indication of serious motor troubles. They can read the ECU faultcodes, which should be a good startingpoint for troubleshooting the cause ...

You could do some basic troubleshooting like checking the air filter, the oil level, the spark plugs, etc. You didn't fill it up with bad gas, did you ? And does the engine make strange noises/vibration when running idle ? In case you fixed some obvious cause, you can dis- and reconnect the battery to erase the engine's faultcode. If it's not fixed, the EPC (and failsafe run) will simply come on again.

My advice would be not to drive it untill it's fixed to prevent more potential damage.

2002 lincoln ls engine light


These cars are famous for leaky seals where the valve cover interfaces with the cylinder head, at the spark plug journals. They fill with oil, short the coils and cause a misfire. Driving it any significant distance can destroy your catalytic converters ad unburnt fuel ignites therein, creating inferno-like conditions and a fire hazard too. You'll get a "300 code", such as 301 if cylinder 1 is misfiring, 302 for # 2, etc. Pull the coil off the spark plug for that cylinder and if it is moist at all, that's your issue. Have new seals put in, or you'll just keep blowing coils at $50 a whack.
