    I re-read my post to you and I realize that it may look like gibberish. Your problem is most likely caused by a faulty mass airflow sensor.

Days after my 50K checkup (no probs), my 2003 VW Beetle convertible check engine light goes on. What can it be & do I really need to take it back to dealer/checkup folks (far & inconvenient)?


The check engine light can be one of many things, even as simple as a loose gas cap. A check engine light means there are error codes in your car's computer. Stop by an auto parts store and ask them to pull the codes. Most of the national chain stores will do it for free. Takes about 5 minutes...

I have a 1998 vw new beetle. The check engine light came on and not sure why. The car seems to be running fine. Last week we replaced the tensioner pulley and a new belt. Now I have the engine light on....


Some auto parts stores scan check engine lights for free. If you can get the code, and tell me what your engine/trans is in the Beetle, I can help narrow down the cause of the check engine light.

Manual can not tell you the problem relaited to check engine light . I mean point the problem . You have to use scaner to retreive the code from ECU and go from there. You could save a lot of money by retreiving code from ECU in the first place , instead of doing guesswork.

whenever this check light is turned on a fault code for the problem that caused the powertrain control module (computer controller) to turn on the check engine light sets a fault code in its memory, this code is key to finding the problem, u can have the system checked for free by any Kragen, Autozone or other discount parts store like them, get the code(s) and post them back here and we will try and give you the answer to what is wrong.

When you say water light comes on, do you mean coolant level, or coolant temp or ? Check coolant level and top off if needed. Bring the Beetle to a parts store, most offer free check of check eng. light. They will plug a hand held scan tool into the cars diagnostic port (usually located under the dash) and 'read' stored engine codes in the cars computer. They can tell you what the codes mean, and suggest what to do. If you have further questions, post them here along with the code numbers.
