Hi Christian,
Earlier this month I answered your question about your car and hope that is is repaired now. I have a favor to ask:
I am competing to be recognized as 'volunteer of the month' at this site. Would take a moment to click on the "Thank/rate the expert" button below? You will then see a question which asks whether to nominate me for that award. If you then click on "yes" that would give me another vote. Thank you for your help.

Hi Christian,
Begin by checking the fault codes:'on-off-on-off-on and leave on' the ignition key, doing that in 5 seconds or less elapsed time. Then watch the check engine light, which remains 'on', to see it begin to flash, pause, flash, etc. Count the number of flashes before each pause. Then repeat to be sure of an accurate set of flash counts. Then write back, telling the counts in order of appearance or go to www.allpar.com/fix/codes.html for a code translation. The codes are found by grouping the counts in pairs in the order of appearach to form the two-digit fault codes, the last code is always 55 because it means 'end of code readout'.
Another possible cause is the egr valve being slightly ajar due to crud. The valve is located near the throttle body air intake at the end of the engine, mounted in a pipe that recirculates exhaust gas from the rear cylider bank exhaust pipe back around to the intake manifold. The exhaust gases have some fumes that can plate out a crud on the valve stem and thus keep it from closing tight when you are at idle. That makes for a too lean mixture so the engine stalls. The valve proper is mounted horizontally with the stem visible in a space between the body of the valve mounted on the pipe and the round top of the valve which is flanged and so if you look carefully you will see a metal rod (stem of the valve) with a slot around its circumference. You can take the tip of flat blade screwdriver and insert it in the slot and then lever the valve back and forth to check if it is moving freely (against spring action in one direction) or not. If it doesn't seem to close easily with the help of the built-in spring, then I would spray the base of the stem with solvent from a pressure can (such as WD-40 or carb cleaner) while moving the stem back and forth. Then see if that solves the issue.
