Hi all,

Started getting hesitations on low revs, when driving around 2000rpm.
Sometimes drive for miles perfect then all of a sudden would start happening......just as if I had lifed foot off throttle then put it back down agaon.
Got worse and worse then eventually engine light came on.

I got a bunch of codes, a few miles after a code reset:

40E9 not present
DDE Exhaust gas circulation controller position control.

4501 present
DDE Exhaust gas circulation control deviation

4C9E not present
DDE Exhaust gas circulation valve plausibility

4C9F not present DDE Exhaust-gas recirculation valve, plausibility

497D not present
Pressure sensor, plausibility while afterrunning: Exhaust pressure before turbocharger not plausible with ambient temperature.

So, I had changed the Exhaust pressure sensor (the one with the 3 bolts that hold it on) a week or so ago, and I also changed the EGR valve this morning (non BMW part).

Alas, after 3 or 4 miles I get the stuttering again, engine light and all the above codes.

I have a temp sensor on order.....the one that fits next to the lamda sensor.

Any ideas.....Love my 330D but it's kinda unusable at the mo!
