Hyundai Tucson CRDi 2007 P1405 and Blinking CEL
Hi,
My Hyundai Tucson CRDi 2007 showed blinking CEL and then constant CEL a month back. OBDII showed P1405 code. Car was not driven at all after the constant CEL appeared until few days back when the CEL was gone (on its own). I took it out for drive of 20km+20km and there it was again - flashing CEL and then constant one with same code.
Also it drove completely normal - as in it didn't feel down on power or had uneven run or anything like that. The idle was smooth too.
I do see that the fuel consumption has gone up by 600ml/100km (7.4 to 8L/100km).
I do have freeze frame data:
LOAD_PCT 7.8%
ETC 81°C
MAP 98 kPa
RPM 1483
Speed 38 kmph
IAT 25°C
MAF 23.0 g/s
FRP 48770.0 kPa
BARO 99kPa
VPWR 14.192V
and
EGR PTC 3.5%
EGR ERR 44.5%
and I found that the glow plug was damaged.
Attached some images for ref.
May be these give a clue?
Has anyone experienced this before and would know the exact problem and potentially a fix?
Thanks in advance
