Hi guys been off the grid for a bit.
4days ago, got the dreaded engine malfunction reduced power message on the I drive and cel light. Went in on Thursday OBD scanned gave me the two above codes. Two hours later, the CEL was gone and all system control check is OK. The next day, again, no light and control check ok. After about 40 miles of driving about. Both the cel and malfunction came and remained on..
No notice of any difference in driving or throttle reduction. As seems and feel normal.
Would this on and off symptom be dirty sensor to the MAF? Or a soon to be on its way out MAF. More importantly, is it safe to drive for couple days till I get a rental a drop off for repairs?
2011 35d 40,200 miles. Latest repair was to urea tank 2 months ago at dealer.
Thanks to all for your time and any inputs for this. Much appreciated
