Hi everyone , i have a w202 and once warm and under load cuts wait 1 minute and starts fine , boot it and cuts out again immediately ,also more noticable when coming round a corner , have put seperate tank on to rule that out , changed seals on all pipes , there are signs of air coming in through clear pipe from filter (also changed ) fault code is p1187 . Please help as this is doing my head in and mercedes have no idea either.

 

p1187 is an issue with the fuel pressure being lost due to the injector leaking off and not holding pressure hence an insufficient spray pattern at the injector and non starting.

That should solve your issue
