I have a 2003 Jetta Wagon 1.8T. The engine light is on and the mechanic guy checked it, it said "misfire". My friend suggests I do a tune-up. I just changed the engine oil and air filter last month. Now I'm going to replace spark plugs, sparkplug wires and fuel filter. I called "Midas", they quoted both parts and labor like $100.65 for sparkplugs, $79.99 for sparkplug wires and $98.68 for fuel filter. Is this a reasonable price?
One more thing is that I checked with Kwik Kar, they said my car doesn't have a fuel filter. Even if I do a full tune-up, there won't be a fuel filter replacement.
I'm confused. Just get this car(my first car) for three months and know little about VW.
Plugs on that car are 2 bucks a piece and they are NGK BKR6E gapped to .032. They are extremely simple to do and paying someone else to do them is a waste of your money. There are no plug wires on a 1.8T as they have coil on plug ignition, the wires running to the ignition coils do not typically go bad at all and should not need to be replaced.
There is a recall on 1.8T ignition coils right now, go see a dealer to get the revised glossy-top versions which fix a lot of common misfire issues.
You have a fuel filter located directly towards the front passenger side of the car after the fuel tank. It is also very easy to replace, the harness is a little tricky to remove but once it's off you're home free. Just remember to pull the fuse for the fuel pump out and then start the car and let it starve the gas lines before it dies out. A fuel filter can be found online at germanautoparts.com for fairly cheap.
Get an OBDII scanner tool and scan the car. Tell us the exact code and we can probably narrow it down for you.
