I have a Mercedes e250 diesel, the car will start from cold

Customer Question

Hi, I have a Mercedes e250 diesel, the car will start from cold no problem in park but as soon as it is put into reverse or drive the engine cuts out. I have changed the transmission fluid and MAF sensor with no difference. If you let the car warm up for 15 minutes its ok all day until the next morning or when it`s gone cold again.
JA: When was the last time your transmission fluid was checked? Changed?
Customer: As I said I have had the transmission fluid changed!
JA: What year is your E250?
Customer: 2011
JA: Are you fixing your E250 yourself? What have you tried so far?
Customer: No
JA: Anything else you want the Mechanic to know before I connect you?
Customer: no
