Hi all, new to Suzuki ownership and am having an issue with the engine light coming on.
We've recently moved to Australia and have purchased a one owner, 125km, sx4 sedan 2.0 auto from a family friend. It's a lovely car but recently the engine light came on. The car went to a mechanic and they changed a sensor (not sure which one of the 2 but can find out) and that cleared the problem for a couple of days.
The light came back on so it went to an auto electrician and they suggested changing the spark plugs, which also cleared the problem, for a couple of days.
I've done a bit of reading through the forum and read about getting oil on one of the sensors (but that's more likely on a 2007 model, right? but ours may be a MY2007 sold in 2008?). Prior to us buying the car it did have a service, the same time as one of the sensors being replaced. Could it be that the sensor was changed prior to the service and the new sensor may be contaminated?
I've also had a thought that using 91 RON fuel may be an issue. I'm from the UK and only used to seeing 95 and 98 RON. Here in Oz we have 91, 95 and 98. Will try a couple of 98 tanks but that obviously won't clear the error
Any other ideas?
Also noted that cruise control has stopped working, but that seems normal if the engine light is on.
Yes, clearing the codes, which shuts off the light and clears the computer's memory, is what the repair shop would have done at the end of their work. It takes several drive cycles (heat up, cool down, speed changes, etc) for the car's computer to verify all systems are up and running correctly. Many of the faults it finds are not displayed until the drive cycle tests are fully completed, possibly taking several days to display.
My description is somewhat simplified but as Aquanaut20 said, the repair shop likely did not replace the truly faulty part. Posting the actual fault codes to the forum is the best way for online folks to help diagnose the problem. Otherwise the guesses we make won't be any different than the guesses your repair shop made and we'll be suggesting you replace parts which aren't the real issue.
