Hi I am new to the forum my car is a UK w210 E280 M112 V6 2.8 engine it runs Dual Fuel LPG which cuts in at 25c idle is good . starting can cause a misfire and error codes to be logged, If I restart the faults clear and the car runs good all day. This is a very erratic problem , I thought it might be the LPG causing the problem so I switched off the LPG problem still there I have cleaned the maf it has new spark plugs all earth points have been re made the air filter is new .


I am getting P0135 P0141 P0136 fault codes ,sometimes P0300 p0304 305 306
can anyone tell me what my fuel trim figures mean , I get Bank 1 closed loop system fault not sure which is bank 1 , a wiring diagram would be good

Is the duel fuel set up a factory modification or modified by yourself!!

Hi Plutoe


Dual fuel was installed by registered installers

Plutoe

Skipping through all the confusing stuff-------not cheap, but you need need new coils and wires on all cylinders---forget about used crap!!!

syseng

That's going to cost then ,may well be a new years project

ohlord

let alone all of them at one time.
They are not your problem and Plutoe is costing you a ton of money even suggesting such nonsense.
Multiple coil failures,Ha ha ha.

Short of setting plug wires on fire or yanking them off the plugs without using the special plug boot removal tool your wires are not the issue either.

i have never owned a MB previous car wasa Mgzs V6 .i cannot see that the coils are the problem the fault goes away after a restart , i will be looking more at o2 sensors i might try swapping them over bank 1 to bank2 and check for fault codes fuel trim figures look different on bank 1 to bank2 i need someone to tell me abt fuel trim i have the data in a excel file
