Hi everyone, This goes on abit but I need to explain the circumstances first!!! I changed the oil two days ago. Yesterday I noticed rumbling when I exceeded 60mph. It thought that the tracking might have gone and was going to book the Copen in to be checked. Today after driving down the motorway (with constant rumbling and steering wheel vibration), I slowed down and stopped at some traffic lights. I noticed that the engine light had turned on and the engine fan was going. I stopped at a shop to buy something, when I started the car up again the engine light stayed on but the rumbling disappeared for a while then after about 5 mins started again. Has anybody got any ideas of what might be wrong with my Copen or what I can do to resolve the problem. Think I might finally have to use a garage and get a diagnosis, but there are no Daihatsu garages! What manufacturer would deal with Daihatsus in the UK?
Sorry, I have no idea what the issue could be. However you don't need to take the car to a dealer. Try the good garage scheme & find a mechanic close to you. They could read the fault code for you & diagnose the problem. http://www.goodgaragescheme.com/ If you really want a Daihatsu garage to check it, have a look at the website to find your nearest service point. http://daihatsu.co.uk/index2.php
if the MIL light has come on, firstly driving can damage the engine it depends on the problem, it suggests an engine/emission issue. So tracking is not the problem unless you have apparently unrelated issues. You must feel some vibrations through the steering wheel to think is suspension/wheel related. When driving at speed did you dip the clutch, come off the gas and let it cruise/roll to see if the problem remained or basically disappeared because the engine dropped down to tick over speed. The latter would indicate it was engine related. You could try: Does the same rumbling occur when not moving and you press the gas pedal to rev the engine to say 3000/4000 rpm or what ever 60 mph would have been and if engine the rumbling possibly will occur. The rumbling may be a rough engine like running on 3 cylinders. have you checked the dip stick to check the oil is at the right level and looks new and not been contaminated. Check underside of the oil filler cap. Is the radiator/water res at correct level? Can you narrow down the locality of the rubbing by listening? But it was some oil change if you knocked the tracking out!
Rumbling Could be your bearings. Could be oil flow problem. First things first, make sure the oil level is at the correct level, and the correct oil has been used. You'd be surprised how many people/garages don't know cars take different oils! You'd think they'd know!! Take it to garage and get it fixed asap before anything major goes wrong.
All I know from making the mistake once myself is that it's a bad idea to drive with the engine light on. You could do more damage and end up with a bigger bill.
ive heard of a similar issue before but was a different car not a copen and basically a women had her car serviced at a garage and one day she was driving and the engine warning light came on and basically what had happened was the sump plug wasnt tightened properly and all the oil dropped out the bottom which caused the light to come on... i would check the underneath of the copen and then check that you have put enough oil in the engine coz i bet thats what it is to do with (the light coming on)
The oil is definitely fine. I have used the same type of oil I used the last 3 times I changed the oil. I have checked the level and it is fine, as is the sump plug. I think the issue is engine related. tonight I stopped off at the service station, when I re-started the car the engine light did not stay on (yay). For about 10 minutes the car was fine, even at 70mph there was no rumbling or juddering. then the rumbling gradually came back, but the light stayed off. I have tried dipping the clutch at speed, but didn't allow the engine speed to drop much. so this didn't really tell me much. I REALLY hope that its not running on 3 cylinders
if it is try the simplest of fixes and change the spark plugs ... i had a fiat that ran badly and its light came on changed the sparks over and all was well and the light stay off permantly
You dip the clutch at speed and come off the accelerator so the engine related noises go and you can listen for wheel/suspension noises or to see if you feel the same rumbling. best to do as you feel the rumbling. If you dip clutch , off gas and it virtually goes and you still travelling same speed its then is engine. It does sound a bit like sparking issues, even plugs or coil. it may be on the cusp of functioning so the light goes out but then comes back on. How old are the sparkplugs? change them like Paul says if not done in past year or 2.
Possibly unrelated: On my (former) Peugeot 207, this would happen - engine light came on and the car kept rumbling. She worked fine apart from the rumbling. It turned out that this was by design! If you missed a service interval, the engine light came on and the car rumbled so you would bring it to a mechanic to reset the code. I doubt this is your case, though. I've not seen anything to indicate that the Copen's ECU forces this.
I checked all the spark plugs at the weekend - they all looked fine. gave them a very light clean with some wet/dry paper. I changed the plugs about 1 year ago. but I've done loads of miles (currently 122000 miles on the clock! This is the first significant problem I've had with the Copen. BTW the engine light has not come on since I first wrote. The rumbling is still there. The rumbling starts around 50mph and if I drive carefully I can increase the speed gradually upto 65mph. The sound is 'percussive'? i.e. bit like whoa whoa whoa whoa (but a rumble, if that makes sense). Starting to think it might be tracking / alignment / bearings. Need to get it into the garage.
