  1. P0068 Mass air flow implausible Totals fault One or more additional faults are entered that more precisely indicate the operating ranges in which the fault occurred. Near idle speed range: P1069 + P1070 + P1071 + P1072 + P1073 Lower partial load range : P1074 + P1075 Upper partial load range : P1076 + P1077 P1023 Fuel pressure/quantity too low at start Possible fault causes Short term failure of the engine speed signal as a result of a crankshaft sensor fault with or without a corresponding fault entry Predelivery quantity or pressure in the fuel low pressure circuit too low Quantity control valve faulty (in fuel high pressure pump) Fuel high pressure pump faulty P1026 Fuel high pressure implausible Possible fault causes (see Fault setting condition(s)) Below limit value: Predelivery quantity or pressure in the fuel low pressure circuit too low Fuel tank (driven) empty See extended fault memory Actual value 40 Fuel Level Input [0%] Below limit value or above limit value : Quantity control valve faulty (in fuel high pressure pump) Fuel high pressure pump faulty Insufficient fuel due to foreign bodies (chips) ahead of the fuel high pressure rail P053f Fuel high pressure after cold start Possible fault causes Predelivery quantity or pressure in the fuel low pressure circuit too low Quantity control valve faulty (in fuel high pressure pump) Fuel high pressure pump faulty Insufficient fuel due to foreign bodies (chips) ahead of the fuel high pressure rail Based on what I see for faults here I would investigate - the fuel pump pressure and flow rate.
  2. You will need a Porsche PIWIS tester ($18,000/year to lease) and your cars IPAS codes (from a dealer). Or a shop with a PIWIS should be able to do that also.
  3. I've had the XPEL on my Macan GTS for over six years and it is holding up real well. I did full hood, door handle (finger grip area), as well as fender surrounds and back bumper .cargo lip. No yellowing that I can tell and the only place it came up a little is on the front bumper where someone"tapped" me. The bumper is fine but the XPEL came up a little from the impact. I do not have any experience with the Hexis.
  4. Sorry, I can't help you with a Mercedes Becker radio.
  5. I do not know how the Kessy or locking system will respond to that - it may trigger a fault.
  6. You should be able to do that but you will need European chassis IPAS codes.
  7. If you get two beeps when locking then you have multiple zones faulting . If you get one beep when locking then you have one zone open/faulting. You need a Porsche specific scanner (like Durametric) to see what zone or zones are triggering or if you have a bad control module.
