Re: check engine light code 0441
You may not have a leak, the problem may be with the sensor on the fuel tank that tells the Power Train Control module if the system holds vacuum, like all sensors these will and do fail on occassion, if you ran a leak down test and the system held vacuum within the manufacturers specs then the sensor may very well be the problem that is turning on the check engine light.
a 6ya Mechanic can help you resolve that issue over the phone in a minute or two.

have a pressure test done on the fuel manifold to check for pump-regulator pressure and filter performance. You state that the filter was last changed in 2007 so it is well past it's blocked up date .. Run fault codes . replace the canister . Have a compression test done as the engine is getting long in the tooth and may need refreshing .. Check that the cat converter is still operational as they will block up the exhaust system and cause poor performance
Check your gas cap. Whenyou put in gas the motor is suppose to be off. If there's not a good seal on gas cap that will cause the check engine light to come on. The mechanic should have a code reader for you and tell you what the light means.
need to start with do you have any obd code with key turned on caddy is more complex system than most , check fully charged battery, and not a jump start, and battery is in very good condition .disconnecting battery would only clear codes leaving you with nothing to go on hopes this is some help to you.
go and take the Scanner +computer Test from another Repair Shop.
however you can go to www. automecanico.com +www.autoelectronico. com this web is spanish, but you can translate, i strong recommend you by powerful information update for any models cars. Try it and fix it for free.
Running rough and misfiring is usually a one or more bad spark plug wires. Don't go back to that dealer. Replace the wires or have your mechanic do it for you. If you replace them, take one off at a time and install the new one. If you put the wires back on in the wrong order, it will misfire.
o2 sensors will put your check-engine-light on. it is attached to the exhaust (closest to the motor)and rusts-out sometimes. you could try to fix it by buying the o2 sensor and use a socket-set to see if it loosens. i 'm not a mechanic but have had the issue, in the past, with the jetta II's and a 1997.the guys at vw dealers are great with info, if your a hands-on kinda guy/girl. mike420
It sounds like to me your mechanic recommened you change your timing belt and water pump due to a maintance issue. If vehicle still runs good with old timing belt new belt wont change running. Cold weather and low cranking amps (poor battery) will cause starting problems.
Cat could have collapsed and exhaust cant get out efficiently but i doubt a cat has failed or oxy sensor for that matter.Why change 1 injector?the vehicle is only 3 years old and should be under warranty it all sounds quite strange and with no other info or specific details i doubt youll get any intelligent answer.Sounds like a lot of people/places have fiddled with your car with no decent outcome?What was the original problem before taking it to auto shops and mechanics and having to replace an injector?
