P0700 on Audi
Transmission Control System Malfunction
P0700 on Audi vehicles indicates transmission control system malfunction. Au7o has documented this code across 3 Audi models — most commonly on A4, A4 Avant, S6. 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. Typical repair costs on Audi range from $1,500 to $6,000, depending on the specific model and root cause.
Common Causes of P0700
- •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
P0700 on Audi by Model
Audi A4(1 issue)
- 2002-2006 A4 Factory-CVT Settlement History - Component-Specific Diagnosis2002-2006
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.
Audi A4 Avant(1 issue)
- Multitronic CVT Transmission Failure2002-2008
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.
Audi S6(1 issue)
- ZF 5HP24 Tiptronic Transmission Valve Body Failure2002-2004
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.

What does P0700 mean on 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 specifically, this code is documented across 3 models.
What causes P0700 on Audi vehicles?▼
Common causes on Audi: 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. Specific causes vary by model and year — see the per-model sections below.
How much does it cost to fix P0700 on a Audi?▼
Repair costs on Audi range from $1,500 to $6,000, depending on the specific model and root cause.
Which Audi models have P0700 documented?▼
Au7o has documented P0700 on 3 Audi models: A4, A4 Avant, S6.
