w211 e320 cdi 2003, Limp mode p2346, solved
Hi, the forum have been a lot af help to me, and now i'll post my solution on a p2346-2 fault (airmass too large egr). I have spend about a month, 5 visits to workshop with star diag. with no result. changed egr valve, mass air, map, pressure and temp sensor - and it still went into limp mode when driving smooth at 80-100 km/h only when warm - no problems when driving 130-140 at the freeway.
solution: The problem turned out to be a clogged egr cooler, where the cooler meets the intake manifold, there was only a 10 % hole remaining, the rest was clogged with soot, i cleaned it with "egr cleaner" and the car is preforming ;-)
