My 1999 ML320 with over 220K has been running great till yesterday. Went for shopping, and when I start the car just crank two or three times. I tried too many times and the same happen. Check the battery, Disconnect/Connect it and the same issue. Used a booster and same thing happen, it crank two or three times and does not start.
Tow my car to driveway and let it for a while. Check the ODBII, no check engine, no other errors. The car lock/unlock normally. Check all interior/exterior light and wipers and everything working fine.
Tried again, and suddenly the car start normally, I shut it off and tried again. The same thing happen, crank two or three times and does not start.
With a key on the position 1, there was no blinking.

I tried again today in the morning, with the key on the position 1 the blinking was normal and in the position 2 just once. Start the car normally and left it till reach the normal temperature 80 C. Restarted three more time after that and everything seems to be normal.
Anyone can shed some light, what it might be?

Thanks,

Hi DrX,
I mean, normal crank time and shut off immediately, It seems engine is rotating 2 or three times.
Thank you,
I am going first with DAS ring & module because when it starts run great and sometimes I drive it for 280 miles.
Anyone have any pictures/part number or DYI? Do I need dealer to reprogram it? I have both keys why should I get a spare?

Regards,
You left out the part where you tried your spare key before you had it towed home from the shops.
My wife, told me that she had the same symptom. She started on the second time with the her key and probably did not notice it. I may have started over 10 time after that with my key before towing.

I guess this is the part 163 545 91 32.

Thank you!
Just order the parts from Parts.com, Total with shipment:$163.34.

Have the EPC start to charge? It has been free before.
Indeed, and I the horrible cost of upkeep on the Bluetec V-6 diesels that customers are getting clobbered by.
.
Bluetec V-6? I almost replaced my 1999 with a 2013. Hmmm... I will hold on for now.

Anyway, just got the parts. Let see how it is going to work.
Great it seems that was the issue. Replaced the brand new DAS ring & module a 15 min job. See DrX post #7 above for the detailed instruction.
Thank you!
