The second one. Now keep appearing leh. I check tangki still full. My service only run 5k km still got another 5k km left.

dat one is SES symbol....you have to send to shop for diagnostic readout to find the cause.

my experience on my car,the emissions system thingy (donno the name) but located above the alternator,with pipelines and an electrical connector connected to it,was at fault.the first time this light appeared,I went to optimum and cucuk the diagnostic and this was faulted,he cleaned the connector and all ok for 1 week afterwhich the light reappeared.i did a 2nd clean of the connector and all is well again.that was 4 months ago.

Moots, did you mean o2 sensors?

 

[moots]

bukan la bro haywire....my O2 sensors are on the headers....i donno the name of the whatchamacallit....i'll see realoem and update later......

 

[Vincentnwc]

How much is the cost for replacing the o2 sensor?

 

[haywire]

As moots said he was not describing the o2 sensor.

However bosch o2 sensors are about 350-400 each

 

[moots]

got it...the wacamacallit thingy is called the fuel tank vent valve...

hence the emissions related issue...

this is for the M54'd e60....

Today I go check oredi. Diagnose says engine misfire. Then the shop reset it and the symbol gone. Anyone tried b4?

 

[lamer2000]

Just drive it around for a few days and see if the fault reappears. Did the diagnostic tool indicate which cylinder is misfiring? It could be a faulty or dying ignition coil which explains the sudden loss in power and vibration

 

[Vincentnwc]

Driven for a few week. Nothing happens. I think should be ok. Anyway thanks bro
