Possible electrical problem

Iaro · 09-28-2016, 11:00 PM

So i had the CBU walnut blast done about 800 miles ago (not sure if its related). Two days ago cel came on so i took it to a german specialized shop to scan. A list of 10 codes is what i got

3EED - Power management closed circuit
p0670 - glow system open circuit control module
p0033 - turbo bypass valve control open circuit
p0193 - rail pressure sensor A circuit high
p0237 - turbo boost sensore A circuit low
p0400 - EGR temp sensor A circuit high
p0403 - EGR control circuit (Exhaust Gas Recirculation Circuit Malfunction)
p0405 - EGR Recirculation Sensor A Circuit Low
p0090 - Fuel Pressure Regulator 1 Control Circuit
4016 - SCR system efficiency

Mechanic that did the scan said its possible there is an electrical problem. He cleared all code and nothing came back, today cel came back, yayyy

Battery was replaced and programed a year and a half ago. Can somebody shine some light on this?

Car has been giving me trouble lately.

Start with simple.. most of those codes are most likely related to him not disconnecting battery /putting the car to sleep when the cbu was performed... Scan again and lets see the codes come up. Simple process of elimination would be to check all connections and work from there.
Start simple then work up..

Took it to my dealer last night bc they did it and they promised to fix for free. Picked it up today. It was a loose connector on crankcase breather, caused all those codes. Hopefully that was it.

Just for the record.
When 3EED shows up, it is always an electrical problem. Either a connection or an internal sensor issue.
