I have a 2008 Beetle with a 2.5 litre engine. The engine service soon light has been coming on for the past 4 to5 months. We have replaced the spark plugs, number 5 cyl coil, changed the battery, serviced the car. We have had the car to a mechanic that works on high end cars and the Volkwagen deal and they cannot get the engine service soon light to stay off. The car now is running extremely rough and the engine service soon light is coming on. The interesting thing is the service soon light is

I did see the service engine light on, brought to some of the near service station but they couldn't fix that. We brought also to the Mitsubishi service station. But they say it is okay, it means they couldn't find the problem too. I checked the oil, it was less than suggested. I add new oil one bottle. Several minutes turned the engine, and the service engine light was off. It happened a month later. I added the new oil, and several minutes later the service engine light was off again. My que

Code drive 5 . My 2004 trailblazer posted a code "drive 5". It showed the "reduced engine poweer" light, and would not respond to the accelerator pedal. I had been driving in slow traffic. I pulled over, turned the engine off, and restarted it. The reduced engine power light went off, and it drove fine, but the service engine light stayed on. The next day, I filled it with gas, and then the service engine light went off. Then I had the code read and it came up "drive 5".
Thottle body sensor, accelerator pedal sensor, restricted air flow...will all trigger this fault light. Go to your local Autozone, they will run an OBD scan for free, and explain the fault codes to you so the correct repairs can be made.Good lu ... 2004 Chevrolet TrailBlazer

My 2005 Nissan Pathfinder Service Engine Light came on at 80,495 miles.I took it to the dealer and after $403.78 worth of repairs code PO455 was replaced an cleared. One month later at 81,159 miles the Service Engine light returned and after $524.73 later, codes U1000 & P0403 were cleared and I was told that my vehicle will need BANK 2 CAT CONVERTER at a cost of $1200.00.

Service engine soon light, loosing engine power light comes on. I hear signals going off. I feel the engine losing power. I pull over and engine dies. I wait a few minutes and it restarts. I drive it home and the service engine light is still on. Mechanic told us it was a dirty throttle. It happened again when I got out of shop. What else could it be?
Sounds like you need to find another mechanic. A dirty throttle wont cause a loss of power. Sounds like fuel pump to me, but you need to have a competent mechanic check the codes, and check the fuel pressure when its acting up. ... 2003 GMC Envoy
I backed the 2004 envoy into my driveway and the engine killed and the reduced engine power light came on along with service engine light also. Restarted the engine and had no throttle while in park position. Shifted car into gear and trottle responded. Parked vehile for a short period of time and then restared and all is now well except for service engine light still on.
You need to check the fuel injection system, throttle body, sensors, check harness for ground. Best solution is to have your engine scanned using Tech 2 scanner. The mechanic will advice you based on the scan code. Whenever the "service engine soon ... 2003 GMC Envoy

I have a 1996 Volvo 850, non-turbo. It has a traction control button near the gear shift (never worked). On the dash idiot lights, ASB, Trax Loc and Service Engine warning lights stay on constantly and have for a long time. I replaced the mass air flow sensor as was indicated when I had a service analysis performed. Is there anyway to turn off any of the warning lights? I tried pulling fuses for the abs and trax loc, but nothing. I know the service engine light is a dealer specialty, but sure

My service engine light just turned on, but I don't notice any problems other than my front right wheel squeaking at times, and during slow turns a "clunk" sound sometimes happens. These problems are most likely bad wheel bearings or suspension, and shouldn't activate the service engine light as far as I know. I have 109,000 miles on my 2000 blazer. Is it possible that the light turned on to remind me to get service done like a transmission flush or tune-up?

I have a 2003 chevy s-10 that displays "service engine light" constantly. Also, the horn does not work. I have replaced the engine coolant thermostat and oxygen sensor which needed replacing. The "service engine light" and horn still do not work. How do I reset the light or turn it off? Help.
Take it to your local trustworthy mechanic. They have a nifty little gadget called a code sensor and they plug it into your car and turn the light off. It takes about 2 seconds. MOST mechanics will do this free of charge, especially one that you freq ... 1996 Chevrolet S-10 Pickup
Started to notice that the engine began to run rough then would be ok for awhile. The service engine soon light would come on when it ran rough and then go out when it ran fine. Now the service engine light is on most of the time and when you accelerate it begins to flash, then stops flashing when you let off the gas. Light still occasionally goes off but not as often. Seems to be worse with cooler outside temperature.
