Hi all.
I've had a problem with my W reg is200 for a few days now. Intermittent juddering and when it does the engine and trc warning lights come on.
Greenflag checked the codes and it said cylinder 5 misfire. Cleared the codes and it worked fine for a few miles and it juddered again - read the codes again and it said multiple misfire cylinder 1 3 and 5.
Having read endless posts on here where people have changed the spark plugs and coil packs with no results I thought it would be best to sell the car as spares or repairs.
However I have noticed in the time I've had this fault I only have the juddering and warning lights issue when I have less than a quarter tank of fuel. When its filled up higher I don't get the problem.
I've spent all day testing this theory and so far it seems that the only logical reason it judders.
I'm goinf to run it above a quater tank of fuel for another few days just to be absolute sure.
would be great to know if those who have had this issue and replacing coil/spark hasn't worked- how much fuel they had in their tank.
I'm guessing on mine it might be a blockage somewhere. It runs like an absolute dream when the tank is above a quater.
