P0087 on Volkswagen: How to Diagnose & Fix
Fuel Rail/System Pressure - Too Low

P0087 on Volkswagen by model: symptoms, diagnosis and fix
Early TSI engines can experience high-pressure fuel pump (HPFP) cam follower wear, leading to fuel system issues. The cam follower rides on the fuel pump lobe and can wear through, causing metal contamination and pump failure.
Common Symptoms
- Long crank time
- Loss of power under load
- Rough running
- Stalling
- Check engine light with fuel pressure codes
How to Fix
Inspect cam follower every 20,000-30,000 miles and replace if worn. Replace HPFP if showing signs of failure. VW issued an extended warranty on some vehicles. Use quality fuel.
Owner tips & cautions
- WarningThis is a high-severity issue - ignoring it can lead to costly repairs or safety concerns. Address it promptly.
- TipGet a proper diagnosis before replacing parts - similar symptoms can have different causes
- TipSearch Volkswagen Jetta forums and owner groups for real-world experiences and DIY guides
- TipGet multiple quotes from independent mechanics - dealer prices can be 2-3x higher for the same repair
The 3.0L V6 TDI engine in the Touareg can suffer from high-pressure fuel pump (CP4.2) and piezo injector failures. The CP4.2 pump is less tolerant of contaminated diesel fuel than the earlier CP3 design and can self-destruct, sending metal shavings throughout the entire fuel system. A single pump failure can contaminate injectors, fuel rails, and fuel lines, requiring complete fuel system replacement. Additionally, piezo injectors can fail individually, causing misfires and rough running.
Common Symptoms
- Engine cranks but won't start
- Rough idle or misfires
- Loss of power under load
- Metal shavings in fuel filter
- Check engine light with fuel pressure codes
- Loud knocking from engine
How to Fix
For CP4.2 pump failure: replace the entire fuel system (pump, rails, injectors, lines) if metal contamination is found ($6,000-10,000). Install a CP4.2 disaster prevention kit (lift pump with filtration) to protect the system ($500-800). For individual injector failure, replace the affected injector(s) ($400-800 each). Always use high-quality diesel fuel and change the fuel filter every 20,000 miles.
The cam follower that drives the high-pressure fuel pump (HPFP) wears through its surface, eventually damaging the camshaft lobe underneath. If the follower wears completely through, the HPFP fails and can send metal debris through the fuel system. Must be inspected every 20,000-30,000 miles.
Common Symptoms
- Loss of power at high RPM
- Long cranking
- Engine stalls under load
- No symptoms until failure (preventive item)
How to Fix
Replace the cam follower at every other oil change (~20,000 miles). Inspect the camshaft lobe for scoring. If the camshaft is damaged, it requires replacement along with the follower.

Approximately 16,737 model-year 2022 Taos SUVs were recalled because the underhood fuel-supply quick-connector may detach from the fuel supply line. If the connection separates, fuel can leak into the engine compartment, which can starve the engine and cause a stall (crash risk) and, in the presence of an ignition source, create a fire hazard. This is separate from the in-tank fuel pump recall and addresses the high-pressure-side line routing under the hood.
Common Symptoms
- Strong fuel/gasoline odor in engine bay
- Visible fuel leak under hood
- Engine stall
- Hard starting
How to Fix
This is NHTSA recall 21V651000 (VW campaign 20DB). Dealers inspect the connection and replace the fuel supply line and connector as necessary, free of charge. Owners noticing a strong fuel smell should stop driving and arrange inspection immediately. Confirm completion via VIN recall lookup.

Volkswagen recalled 15,874 model-year 2022 Taos vehicles (built March 24 - August 11, 2021) because the in-tank fuel delivery module can break during operation. The module can seize if foreign material obstructs it or the impeller is deformed or improperly positioned, interrupting fuel flow. The result is illumination of the EPC (electronic power control) warning light and often a check-engine light, followed in rare cases by a sudden loss of engine power while driving, which raises crash risk.
Common Symptoms
- EPC warning light
- Check engine light
- Sudden loss of engine power while driving
- Stalling
- Hesitation / hard starting
How to Fix
This is NHTSA recall 23V214000 (VW campaign 20DV). Affected owners should have the fuel delivery unit replaced free of charge at an authorized VW dealer; VW also reimburses prior out-of-pocket repairs. Verify your VIN against the recall on the NHTSA or VW recall lookup.

The high-pressure fuel pump (HPFP) on the Atlas 2.0T engine can fail, causing extended cranking, rough running, or a no-start condition. The pump is cam-driven and sits on top of the engine. Internal wear causes insufficient fuel rail pressure, and in some cases metal debris from the failing pump contaminates the fuel system requiring more extensive cleaning.
Common Symptoms
- Long cranking before start
- Engine stalling
- Loss of power under acceleration
- Check engine light
- Rough idle or misfires
How to Fix
Replace the high-pressure fuel pump with the updated revision. If metal debris is found in the fuel rail, the fuel injectors and fuel rail must also be cleaned or replaced. A fuel system pressure test should be performed before and after repair to verify proper operation. Keep fuel tank above 1/4 to reduce stress on the low-pressure pump which feeds the HPFP.

Frequently asked questions
What does P0087 mean on a Volkswagen?
P0087 stands for "Fuel Rail/System Pressure - Too Low." 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. On Volkswagen it is documented across 6 models: Jetta, Touareg, CC, Taos, Atlas, Eos.
What are the most common causes of P0087?
The most common causes of P0087 are: 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). The specific cause varies by vehicle.
How much does it cost to fix P0087 on a Volkswagen?
Published repair estimates on Volkswagen range from $20 to $10,000 depending on the model and root cause. If an issue mentions a recall or campaign, check your VIN with the manufacturer or NHTSA and confirm eligibility and coverage with a dealer.
