P1136 on Audi
Intake Valve Timing Control Solenoid Valve Circuit, Bank 2
P1136 on Audi vehicles indicates intake valve timing control solenoid valve circuit, bank 2. Au7o has documented this code across 3 Audi models — most commonly on A4, Q5, SQ5. A Nissan/Infiniti manufacturer-specific code. The ECM pulses the intake valve timing (VVT) control solenoid with an on/off duty signal to route oil that advances or retards intake cam timing, and this code sets when it sees an abnormal electrical condition in that solenoid circuit on Bank 2. Symptoms are usually a check engine light with mild rough idle, reduced low-end power, or slightly worse fuel economy. On these engines the fault is very often oil-related rather than a bad part, so change the oil and filter (and try cleaning the solenoid) before condemning it. Other makes use P1136 differently - VW/Audi assign it to a Bank 1 lean additive-mixture fuel trim fault.
Common Causes of P1136
- •Dirty or degraded engine oil clogging the intake valve timing solenoid
- •Low engine oil level or the wrong viscosity
- •Failed intake valve timing control solenoid valve (Bank 2)
- •Open, shorted, or chafed wiring in the solenoid circuit
- •Corroded or loose solenoid connector
- •Failed ECM (rare)
P1136 on Audi by Model
Audi A4(1 issue)
- 2009-2021 A4 2.0T Gasoline-Quality Deposit Diagnosis - TSB 2014753/132009-2021
Audi states that contaminated gasoline or gasoline with insufficient deposit-control additives can contribute to deposits on intake valves, the intake manifold, fuel injectors and combustion chambers. Possible results include rough running after cold start, extended cranking, hesitation, rough idle, reduced performance, poor fuel economy or an MIL with supported misfire, lean-system or cylinder-imbalance faults. This does not establish a universal A4 2.0T intake-valve defect, mandatory walnut-blasting interval or fixed failure mileage.
Audi Q5(1 issue)
- 2009-2025 Q5 Gasoline-Quality Deposit Diagnosis - TSB 2014753/132009-2025
Audi states that contaminated gasoline or gasoline with insufficient deposit-control additives can contribute to deposits on intake valves, the intake manifold, fuel injectors and combustion chambers. Possible results include rough running after cold start, extended cranking, hesitation, rough idle, reduced performance, poor fuel economy or an MIL with misfire, lean-system or air/fuel-ratio-imbalance faults. This does not establish a universal Q5 intake-valve defect, a mandatory walnut-blasting interval or a fixed failure mileage.
Audi SQ5(1 issue)
- Fuel-Quality or Deposit-Related Rough Running and Misfire Diagnosis2014-2025
Audi states that contaminated gasoline or gasoline with insufficient deposit-control additives can contribute to deposits in injectors, combustion chambers, the intake manifold and intake valves, with rough running, hesitation, reduced performance, poor fuel economy or related ECM faults. This does not establish a universal SQ5 intake-valve defect, a mandatory walnut-blasting interval or a fixed mileage. Audi separately warns that unapproved fuel additives are not permitted on 2018-2025 EA839 V6 TFSI SQ5 models because a negative effect on engine life cannot be ruled out.

What does P1136 mean on Audi?▼
P1136 stands for "Intake Valve Timing Control Solenoid Valve Circuit, Bank 2." A Nissan/Infiniti manufacturer-specific code. The ECM pulses the intake valve timing (VVT) control solenoid with an on/off duty signal to route oil that advances or retards intake cam timing, and this code sets when it sees an abnormal electrical condition in that solenoid circuit on Bank 2. Symptoms are usually a check engine light with mild rough idle, reduced low-end power, or slightly worse fuel economy. On these engines the fault is very often oil-related rather than a bad part, so change the oil and filter (and try cleaning the solenoid) before condemning it. Other makes use P1136 differently - VW/Audi assign it to a Bank 1 lean additive-mixture fuel trim fault. On Audi specifically, this code is documented across 3 models.
What causes P1136 on Audi vehicles?▼
Common causes on Audi: Dirty or degraded engine oil clogging the intake valve timing solenoid, Low engine oil level or the wrong viscosity, Failed intake valve timing control solenoid valve (Bank 2), Open, shorted, or chafed wiring in the solenoid circuit, Corroded or loose solenoid connector. Specific causes vary by model and year — see the per-model sections below.
How much does it cost to fix P1136 on a Audi?▼
Repair costs vary widely depending on the root cause and specific Audi model.
Which Audi models have P1136 documented?▼
Au7o has documented P1136 on 3 Audi models: A4, Q5, SQ5.
