Ok..In regards ***** ***** mentioned warning the toxic fume warning is basically the vehicles exhaust gas monitoring system - more often that would flag up if there is a monitored change in fuel/air mixture ratios as per the exhaust gas maybe caused by an engine management sensor running out of parameters or either ignition system fault - ie:- failing coils thus the fuel injected isn't being burnt efficently and this is where the emissions system picks this up or as you say maybe a duff sparkplug but usually a slight missfire/power loss would be experianced usually and seeing as you have had it serviced recently and plugs where included i cant see it being them unless there cheap plugs - other issues associated can be faulty oxygen sensor/or a failed cat converter - from what your saying it could well be failed cat or ignition coil but hard to say without having the fault codes at hand -
The best way forward really from this stage on and any garage would do this anyway as a first port of call - would be to get the car on a diagnostic machine and retrive the fault codes from the cars ecu and see whats been seen by the ecu as faulty as this will give a better idea or understanding as to what you need to do and check so to speak..so any good reputable garage or mobile mechanic even with the proper equipment to plug in should be able to that for you..I do hope this helps..If you need to ask anything else or include any further info then just continue before you rate
thank you very much do you think this an expensive repair?
Its pretty hard to say/answer at this stage with these kind of faults..at any point i get vehicles in my garage with problems such as yours it "has" to be scanned on diagnostic machine usually most test fees are in the £20 range nowadays..to see what fault codes the ecu has logged only then can you move forward in regards ***** ***** repair/fix and too whether its going to be expensive or not..I do hope this helps further
thanks i have looked at some prices for items you have mentioned
Yes ..but the diagnostic test has to be the first step with faults like you have to be able to see exactly the fault occuring..before even considering purchasing parts that may not be required...
thanks i wouldnt buy anything just wanted a rough idea
