Hello, everyone,
New guy here, I am stuck in a never-ending loop of issues with my 2014 ML350 Bluetec. It all started with a check engine light in December supposedly caused by the differential pressure and exhaust back pressure sensors - fault code 111500 'Soot content in the diesel particulare filter is implausible'. Changed both sensors to no avail. The DPF was not regenerating and fuel consumption was through the roof (23l/100) which made me install a brand new DPF. This solved everything up until this moment, fuel consumption stabilized, no more CEL.
Only 300 km later, another CEL came up, and shortly after, the dreaded Adblue Remaining Starts 10 message. Note that there was no prior Adblue-related message about "500 km remaining" or "16 starts remaining" - straight to 10 starts. At the time, I thought it was caused by low Adblue level, so I filled it up, which did not clear the CEL. Not only that, but the car started heavily smoking grayish/white from the exhaust and smelled as nothing I have ever smelled - neither diesel fuel smell nor ammonia (as fas as I could tell). After clearing the fault codes (16CE00, 16CF00), it all settled only for another 200km, before CEL came up again.
The official dealer advised me to perform a software update of the ECU since apparently the Adblue system was not properly communicating with the ECU - this fixed the Adblue-related codes, but I am now dealing with 14CF00 - 'The positive control deviation during exhaust gas recirculation control is too high' + 178200 - 'Efficiency of SCR catalytic converter'. The 14CF00 code prompts CEL and has been sporadically present ever since the DPF issues started in Decemver - the dealer claims I now have to clean the EGR valve, pipes, etc. This is fine and I will do it - my main worry is where does that damn smoke come from - could it be because of the EGR issue, the Adblue issues or the newly installed DPF? The smoke only started after filling the Adblue tank, but this was also shortly after DPF replacement which makes me think it could be either. The smoke comes up randomly during both highway and urban driving, lasts for about 2-5 minutes and stops. "Its just DPF regeneration" the dealer says, which doesn't seem plausible to me, given that its a new DPF and I never had such issues previously - only after the Adblue issues started.
Any advise would be appreciated.
