2014 Sportwagen with 44,000. 3rd owner this was a buy back car so detailed service history not know.
Car starts and runs fine for 15 to 20 mins, or until it gets hot. Once at temp, and I push it over 2000 rpm get the flashing glow plug lamp and a P0087 fault. Let the car cool down and it runs fine again until it gets hot. Changed the filter, it was original, and pulled the modulator NO metal gunk in the hole or on the screen. VCDS, yes I bought it from Ross Tech, tells me that the requested pressure was around 1500 bar and the actual was around 1000 bar, given the document i just read this would be within the quoted 230 to 1800 bar of the pump.
I Electrical Engineer in me says its probably a heat soaked pressure switch, but it could be the regulator. Any thoughts or comments?
One last question, where is the pressure measurement port, i understand 1800 bar is not to be mess with, but to verify the pressure readings you need to install a gauge. There looks to be a plug under the output line from the HPFP. Is this the gauge port?
