Cng light indicators

[kasaas]

I"VE BEEN HAVING THIS PROBLEM FOR THE PAST 4 MONTHS NOW THAT MY CARS CNG FILLS UP FOR ONLY RS 160 (IT USED TO COST ME RS 230+ TO FILL UP BEFORE).ALL 4 LIGHTS LIGHT UP BUT AFTER FEW MINUTES 2 OR 3 LIGHTS REMAIN AND IT KEEPS FLUCTUATING.
WATS THE CAUSE?? IS IT LOW PRESSURE AT CNG STATIONS OR IS THERE SOMETHING WRONG WITH THE KIT?

[hassam]

id suggest try filling up the gas from TOTAL CNG station after 12 mid night or early in the morning before 6am. at this time, pressure is at its peak.

in daytime my cars 55kg cng tank fills for max 250. but after couple of kms, only 3 lights are left. if i fill after midnight it fills for rs 320 or rs 325

try it first..

@hassam,but this shouldn't be a cause of fluctuating LEDs,right?

[ibnealy]

try different filling stations and if pb remains..
then get it checked:)

okie.. thats a very common problem for CNG users.. Dude just get your kit and cylinder service.. you'll find some kachra and oil in your cylindler which lessens your cylindre capacity.. if you really want get good gas then i'll tell you some good stations.

1. Total Feul Pump in between Firdaus Market to Hussain Chowk
2. Total Gin Filling, QUeens Road
3. Gas Station in Liberty in front of Dunkin Donuts..

yes also get your sensor checked..

thanx every 1 for the replies.
@ air explorer i meant that the led starts at 4 then goes to 3 or 2 and some time latter again to 4 and then whole cycle happens again.
I ve been using diffrent stations in the defence area only.Will try out total next time.
Thanx

There are two type of sending unit for the LED display. Which one do you have. The one which has cable connector on the top of transparent cover of pressure gauge..OR.. the second type in which pressure sensore and gauge are seperate.

seems like oil accumulation in cylinder killing space in cylinder

hassama bhai!
325 is for sure...
lahore mai itna pressure
round da clk hv checked dozen of cng pumps..
but nywayz..
55 k size ka cylender mai actually 8 kg gas bharni chahiye..lekin gas bharti hai 8.85-9.55-10 kg
well my cultus did a gjw tour in one cylender aur abhi b aik point tha green...
@ da speed ov 110max
4 passengerz
hassam bro u knw na where do i live..

well bhai aap ki gaddi ka jo points ki fluctuation ka rolla hai...yai kabi b nai mukkey ga..inshaALLAH

@ysalman...........the first one

[shanii123]

@ kasaas bro!

yara..
gas gauge ka prob tou hai ee..coz it dosnt work properly as u said k kabi 4 tou kabhi 2 aur phir 4...
lekin as u r sayin k juz 160 km...tou yara...1000 cc k liye yai enuf average hai..coz..purani carz lyk 2000 cultus ya 98-99 khyber b yai ee average day rain haIn..
agr app ki car pehlay ziyada average deti thee tou yai possible hai k gas station theek na hou!
hassam is ryt! app rush hours mai gas na fill krwaya kro..
actually cold atmosphere mai aur non rush hrz mai ee gas lainay ki try kia kro...
aur kisi din motorway ka mood ho tou thookar wali side say jaaiye ga aur motorway say pehlay MOTORWAY CNG aata haie..mai last 3 months say odhr say ee gas lai raha houn...damn gud average nd gud pressure..coz odhr rush nai hota..pressure acha mill jata haie

Buy a new indicator worth Rs 500/-

if the problem remains the same after getting ur gas filled from a good cng station then immediately get ur cng sensor (installed in cng kit) checked from a reliable place. i think the original landirenzo sensor will cost u around 7000 Rs.

DIY- Type 1 CNG sensor cleaning.

• Remove the cable connector from the top of gauge
• See if the pins are rusty (Clean both male and female sides)
• Remove the tranparent cover (There will be a think slot in between Transparent cover and blak base, use screwdriver)
• You will see few LED type sonsors inside the cover (See if they are clean, or remove the circuit from the cover and see if there is any thing looks wrong)
• Now connect the cable with sensor without placing the cover to base (you shoud observe 4 lights on indicater)
• Observe if the inner part of gauge isnt dusty and niddle movement is ok.

Logic is that the niddle gradualy covers the 4 sensors inside the gauge when the CNG pressure dropps, to reflect the status.
Note: Ignition switch should remain off except when u checking the sensor in last steps
