sorry for being late bro.
for ur queries...here u go.
1) this shud b a problem wid ur cng kit software(yes thats wat they call it)u need to get the software re-done to adjust when do u want ur car to switch to petrol.u can fix it at any point u want
2)no this isnt any issue.that is the EPS warning light.EPS means Electronic Power Steering.This is a system which assists in steering the steering wheel.This is not activated until u start the car ,so it shows u that the system isnt activated yet.after u start the car,if goes off n steering get very soft. plz note that this power steering of city is very much different then normal power steerings.this one doesnt need any oil or any type of maintanence.its electrically powered.
3) for tuning, i cant say about the professionalizm of those ppl as i havent tried them.but yes,2000rs is too much.Honda guys in sargodha charge 1000rs n wat they do is to adjust tappets and clean the throttle body.
let me know wats the milage of ur car n when were the last tunings done(if u know) then we ll see if it needs tuning yet or not.
4)there are lot of them.the BEST one is to not take ur car to ANY mechanic unless it gives u any problems.change ur cars plugs every 20,000kms. change gear oil every 40k kms.air filter every 10k kms.timing belt(timing chain actually) doesnt needs to be changed,so dont be concerned about it no matter how much ur car is driven.
do not spray oil under the car after service.avoid getting the engine washed at service stations, they use a lot of water pressure which can b dangerous.wash it at home wid low pressure.
thats all for now,ask anything else u want to know too.
