P0700 on Audi by model: symptoms, diagnosis and fix
The ZF 5HP24 Tiptronic automatic transmission develops valve body issues causing harsh shifts, delayed engagement, and eventually limp mode. The electronic solenoids and valve body bore wear are the primary failure modes.
Common Symptoms
- Harsh shifts
- Delayed engagement
- Transmission limp mode
- Gear hunting on hills

The 2013 settlement covered U.S. 2002-2006 A4 vehicles originally equipped with a factory-installed CVT. It used component-specific branches: TCM for 2003-2006; valve body for 2003-2004; and transmission without valve body/TCM for 2002-2004, subject to maintenance proof. Plaintiffs alleged improper function, while defendants denied defect, wrongdoing and liability and the court did not decide the merits. The notice does not establish every CVT symptom as a failed transmission.
How to Fix
Verify the VIN, original U.S. factory-CVT equipment, transmission code, faults, fluid/maintenance records and reproducible behavior. Diagnose the TCM, valve body and mechanical transmission separately and replace only the confirmed component. The historical 10-year/100,000-mile terms and November 18, 2013 reimbursement deadline are expired; do not promise coverage or buy a TCM, valve body or transmission from this record.

The Multitronic CVT used in front-wheel drive A4 Avants is prone to premature failure of the chain, pulleys, and control unit. This transmission has a poor reliability record and is expensive to repair.
Common Symptoms
- Shuddering
- Loss of drive
- Jerking during acceleration
- Transmission warning light

Frequently asked questions
What does P0700 mean on a Audi?
P0700 stands for "Transmission Control System Malfunction." P0700 is a general code indicating the transmission control module (TCM) has detected a fault somewhere in the transmission control system and has requested the check engine light be turned on. By itself it doesn't pinpoint the problem — it's an 'umbrella' code that tells you to look for additional, more specific transmission codes stored alongside it. The actual fault could be electrical, a sensor, a solenoid, or an internal transmission issue. You may notice harsh or delayed shifts, slipping, or the transmission going into a protective 'limp' mode. On Audi it is documented across 3 models: S6, A4, A4 Avant.
What are the most common causes of P0700?
The most common causes of P0700 are: Stored companion transmission codes pointing to the real fault, Faulty shift solenoid or pressure control solenoid, Low, dirty, or degraded transmission fluid, Faulty transmission speed or input/output sensor, Wiring, connector, or ground problems at the transmission, Failing transmission control module (TCM), Internal transmission mechanical wear or clutch problems, Valve body fault or sticking valves. The specific cause varies by vehicle.
How much does it cost to fix P0700 on a Audi?
Published repair estimates on Audi range from $1,500 to $6,000 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.
