Fault Code Question

[DLessilexi]

Hi LOC

I am an owner of a IS220d and have been for 3 years now. I have lived with the usual trials of dpf and egr valve. One is removed the other cleaned twice. We have now developed a new problem that is a little more concerning. Whilst driving on M1 recently, whilst slowing for traffic the car spluttered to a halt unde braking. Car would not restart leaving me stranded in 3rd lane!! Tried to restart it a few times but nothing.....After about 20 minutes of butt clenching I tried the car again and it fired up. When AA arrived they said there was a fault code of P1427 or P1427P? Anyone have any pointers as to what this code is as it seems elusive to me? Anyone else had this problem? Car runs fine at the moment but warning lights quickly illuminate once codes erased and its a little nervy to think of driving it. Thank you in advance for any advice.

Did you get this sorted?

That code looks like it's the MAF sensor. It mentions a short circuit. I'd check the sensor, unplug and clean it, check wiring.
