We bought this car at 101000 from dealer with full Benz service and the oil cooler leaked fixed at dealer prior to purchase. Now at 116000. Have been using the recommended mobil one but have realized that may be contributing to problem. Car has been running fine with exception of oil consumption ( learning this is a sign that it could be leading to DPF clogging as result of wrong mobile one oil , have done two oil changes and I used the ESP mobile one oil) . So wife was driving down road accelerated hard let off and car died would not restart after one try then would not even turn over. Turned motor over by hand not sized . Checked all Fuses then pulled codes. No blown Fuses code 111500 particulate. Have owned a diesel the older 350s for 218 thou 324,000 total on odometer and still on road and 300d for 200 plus all maintain and repairs with exception of injector pump done at home, can do all maintenance and most major repairs but a little lost with all the new electrical stuff. Some things are pointing to remove the DPF and get cleaned? after the testing and checking tested battery again and was down to 11.5 so it is charging- it was at 12.3 when I first started diagnosing , have read what I can just looking for a little direction/help as to where to start.
