P0087 on Audi
Fuel Rail/System Pressure - Too Low
P0087 on Audi vehicles indicates fuel rail/system pressure - too low. Au7o has documented this code across 1 Audi model — most commonly on A4. This code means the fuel rail or fuel system pressure has dropped below the level the engine's computer expects. The computer monitors a fuel pressure sensor and has seen pressure fall too low, meaning the engine isn't getting enough fuel — especially noticeable under acceleration or load. This is most common on direct-injection and diesel systems that run very high pressures. Symptoms include hard starting, stalling, hesitation, lack of power, and possible limp mode.
Common Causes of P0087
- •Clogged or dirty fuel filter
- •Weak or failing fuel pump (lift pump or high-pressure pump)
- •Faulty fuel pressure regulator or control valve
- •Restricted or leaking fuel lines
- •Faulty fuel pressure sensor
- •Air in the fuel system or running low on fuel
- •Worn high-pressure pump (direct injection/diesel)
P0087 on Audi by Model
Audi A4(1 issue)
- 2005-2007 A4 2.0TFSI Cam-Follower / HPFP Diagnosis - TSB 2013147/122005-2007
Audi TSB 2013147/12 applies to 2005-2006 A4 vehicles with the BPG engine and 2007 A4 vehicles with the BWT engine when the MIL is on and P2293 is stored; P0087 or P1093 may accompany it. Audi’s procedure checks fuel pressure and wear at the cam follower, intake camshaft lobe and high-pressure fuel pump. The documents do not publish a universal inspection interval and state the covered condition does not cause stalling.
