I was driving to work this morning and the EPC light came on. The car will not accelerate over 30 MPH. The Tachometer when it hits 3500 rmp the engine shakes and sputters. The car is at the Audi dealer now. Has this happened to anyone else? what was the issue? :wall:

I found this in search: still awaiting from Audi on my car!

EPC Light comes on at 4000 rpm - clears on restart


The DTC code is as follows:

00135 P0087 fuel rail/system pressure too low

Possible causes

  • - Fuel pressure sensor harness is open or shorted
  • - Fuel pressure sensor electrical circuit poor connection
  • - Faulty fuel pump
  • - Blocked fuel filter
  • - Fuel line restricted
  • - Faulty fuel pressure regulator
  • - Faulty fuel pressure sensor
 
  • Helpful
