2 Faults - Both Electrical

Fault A
Both Remotes on the C200k 1.8 53 plate (Sport coupe)
Stoped responding / intermittant
First port of call is the batteries - sorting that, but is there a way to resync the car to the remotes like tapping lock and unlock sequences?

Where is the Antenna so we could check for signs of loose wires or something, its started happening randomly and isn't getting better

setting the alarm off isn't fun.....


Fault B
Recuring Po172 - system to rich

I took these 3 snap shots of the Scan Tool Diagnostic that seems to be working a treat with it

The fault is reoccouring as said, it varys from time to time as to how long it'll take to come back

I'm believing its the lamab sensor but this is where i need your help





different revs give different results to the Fuel 1 system Status

Note 2 A Says O2 Fault
Now 02 Sensor usually means lamba?

When i watch the lamba voltages - when you hold it at 4krpm, the voltages go up to about 0.875 / 0.9
When its idling its about 0.05 / 0.1
So its the extreme's when running
Would this be a good a clear sign? or we need more screen shots


Many Thanks in advanced
