My c70 engine managment light keeps coming on , i have been told it fuel / air mix is this correct ? is there any simple things i can try to solve this problem ?
Yes I have the same problem - check engine light keeps coming on code P0014 Camshaft position sensor actuator B timing.
This car drives like a dream, except in the rain when it tends to self accelerate at red lights (yipee!)
Dealer tells me the problem is poor maintainence by first owner and that the engine is sludgey, except.... I've had over a year of driving without this problem. Bought the car 2 years ago and had an initial problem but then it went away, once this sensor was changed.
Have brought it back for this same code and don't cha know that instead of changing the sensor per my request, they did $1400 worth of work that did fix anything, and are now having to change that sensor for free.
What do the mechanics say.... that these sensors are super touchy and have the customer coming back again and again.

Read OBDII codes for direction. P0116, P0117, P0118 codes indicate an engine coolant temperature sensor circuit or sensor performance problem. Further testing is necessary to determine root cause i.e. broken wire or failed sensor.
A simple visual inspection of the coolant temperature sensor and sensor wiring may reveal the problem.
Correct reporting of engine temperature is necessary for the fuel management system to determine proper air/fuel mixture. Your sensor is reporting hot while engine cold which likely effects a lean air/fuel mix causing multiple cylinder misfires.
Possible plugged catalytic converter ! is the check engine light on ? You should take it an have scan tool hooked up to see if any codes are stored in any control modules ! An have exhaust system pressure tested !
the CO and fuel/air mixture is not adjustable on modern cars , only on carburettors . the engine management system will ensure correct fuelling, if there is a fault with this then in most cases an engine management light will illuminate on the dash board
The fuel emission light operates from several sensor that if one is out of parameters tells the CPU that the air fuel ratio is incorrect and so the light comes on. IT may be a MAP/MAF/VAF sensor or a ambient air temperature sensor that is not reporting correctly. Have the fault codes read and see what has been recorded and work from there. The engine will operate alright but there may be a slight decrease in economy that you would not notice unless you record the fuel consumption manually.
Black smoke is burning oil. Blue smoke is usually transmission fluid due to a leaking modulator valve in the older auto transmission. White smoke is due to water getting in to a cylinder from a bad gasket, cracked block or a cracked head.Black smoke from engines on starting and/or running tends to mean there is fuel leaking into the engine, or the fuel mix is incorrect and not atomised correctly. the main causes are normally a nakered air filter that isnt letting enough clean air into the engine to mix. a blocked fuel filter, which is either not letting enough fuel in, or in some cases, a faulty fuel filter which is letting too much fuel into the engine, and causing black smoke due to excess burning. Black smoke is a fuel/air mixture suggestion problems with injection or carbonation. Cause of black smoke is due to running rich in the fuel air mix.Check the oil,the oil leak,the air filter,the fuel pump and fuel filter to confirm the fault.

It could be, but any of those would set a fault code and eventually turn the check engine light on. You may want to test for a blown head gasket. Coolant will seep into one or more cylinders and foul the plug until the engine warms up and clears the plug.
so all the lights that come on when you first turn the key on stay on? maybe your alternator is not working properly? or not connecting to your dash panel correctly? or maybe the engine management system has a fault in it? more likely to be a dodgy connection to your dash board.
Don't know why C70 has been auto added to my car problem. It's a V40.
