<strong>600640600A</strong> / <strong>6006406-00-A</strong>) is the pneumatic distribution and control assembly at the heart of the air suspension system on the <strong>Tesla Model S</strong> (2012&#8211;2016), <strong>Tesla Model 3</strong> (2017&#8211;2020, air suspension variants), and <strong>Tesla Model X</strong> (2016&#8211;2020). The same physical assembly is used across a range of VAG Group and Porsche air suspension platforms including the <strong>VW Touareg</strong> (7L), <strong>Audi Q7</strong> (4L), and <strong>Porsche Cayenne</strong> (955/957/958), reflecting the shared RAPA-manufactured valve block design. The unit contains seven solenoid-controlled valves arranged in a single manifold body: one inlet valve for compressed air from the compressor, four corner valves directing air individually to each air spring, one exhaust valve to atmosphere, and one pressure reservoir valve. The Tesla Suspension Control Module sends electrical commands to each solenoid, opening or closing individual valves to raise or lower specific corners of the vehicle, maintain target ride height under changing loads, and deliver sport, comfort, or maximum clearance suspension modes. </p> <div class="qf-spec-row"> <div class="qf-spec-item"><div class="qf-spec-label">Tesla OEM (primary)</div><div class="qf-spec-value">600640600A</div></div> <div class="qf-spec-item"><div class="qf-spec-label">Tesla OEM (dash format)</div><div class="qf-spec-value">6006406-00-A</div></div> <div class="qf-spec-item"><div class="qf-spec-label">Component type</div><div class="qf-spec-value">Air suspension solenoid valve block</div></div> <div class="qf-spec-item"><div class="qf-spec-label">Number of ports</div><div class="qf-spec-value">7 (inlet + 4 corners + exhaust + reservoir)</div></div> <div class="qf-spec-item"><div class="qf-spec-label">OEM manufacturer</div><div class="qf-spec-value">RAPA (same production line)</div></div> <div class="qf-spec-item"><div class="qf-spec-label">Weight</div><div class="qf-spec-value">~0.6 kg</div></div> </div> <div class="qf-sub-head">Cross-Platform OEM Number Family</div> <div class="qf-cross-grid"> <div class="qf-cross-card"><div class="qf-cross-brand">Tesla OEM</div><div class="qf-cross-num">600640600A / 6006406-00-A</div><div class="qf-cross-status">&#10003; Primary &#8212; this part</div></div> <div class="qf-cross-card"><div class="qf-cross-brand">Tesla (earlier revision)</div><div class="qf-cross-num">1027919-00-A / 102791900B</div><div class="qf-cross-note">Earlier Tesla revision &#8212; same unit</div></div> <div class="qf-cross-card"><div class="qf-cross-brand">VW Touareg (7L) / Phaeton</div><div class="qf-cross-num">7L0616007F / 7L0616007H</div><div class="qf-cross-note">Touareg air suspension</div></div> <div class="qf-cross-card"><div class="qf-cross-brand">VW Touareg (7L)</div><div class="qf-cross-num">7L0698007 / 7L0698007A</div><div class="qf-cross-note">Touareg air suspension</div></div> <div class="qf-cross-card"><div class="qf-cross-brand">Audi Q7 (4L)</div><div class="qf-cross-num">4L0698007 / 4L0698007A / 4L0698007B</div><div class="qf-cross-note">Q7 air suspension</div></div> <div class="qf-cross-card"><div class="qf-cross-brand">Porsche Cayenne (955/957)</div><div class="qf-cross-num">95535890102&#8211;105</div><div class="qf-cross-note">Cayenne PASM</div></div> <div class="qf-cross-card"><div class="qf-cross-brand">Porsche Cayenne (958)</div><div class="qf-cross-num">97035815302&#8211;324</div><div class="qf-cross-note">Cayenne 958 air suspension</div></div> <div class="qf-cross-card"><div class="qf-cross-brand">VW Touareg (7L) R50</div><div class="qf-cross-num">7L8616006D</div><div class="qf-cross-note">Touareg R50 variant</div></div> </div> <div class="qf-sub-head">How the Valve Block Works</div> <p class="qf-para"> The valve block is mounted in the front compartment of the Tesla Model S and X alongside the air suspension compressor. Compressed air from the compressor enters the valve block through the inlet port. Inside the manifold, seven solenoid valves controlled by the Suspension Control Module (SCM) open and close to route or block air flow. To raise a corner, the SCM opens the inlet solenoid and the solenoid for that corner&#8217;s air spring simultaneously &#8212; compressed air flows through the manifold into the air line to that spring, inflating it and raising the corner. To lower a corner, the SCM opens the exhaust solenoid and that corner&#8217;s solenoid &#8212; air from the spring vents through the exhaust port to atmosphere. The four individual corner solenoids allow the SCM to adjust each wheel independently, compensating for lateral load transfer in cornering and enabling the level correction that eliminates front and rear dive under braking and acceleration. </p> <p class="qf-para"> The valve block body is constructed from engineering-grade plastic with aluminium inserts at the VOSS push-fit air line fittings. The solenoids are sealed by internal O-rings that separate each valve chamber. Over time, the O-rings degrade through heat cycling and dry out from moisture contamination in the air system &#8212; a depleted desiccant filter allows atmospheric moisture through the compressor, accelerating O-ring deterioration. A failed O-ring allows air to bypass between chambers, producing a slow continuous leak that overworks the compressor and results in suspension height faults. </p> </div> </div> </div> <!-- BLOCK 2: SYMPTOMS & DIAGNOSTICS --> <div class="qf-block"> <div class="b-section"> <div class="b-header" onclick="qfToggle('b2')"> <div class="b-title">Symptoms &amp; Diagnostics</div> <div class="b-chevron open" id="qf-chevron-b2">&#9650;</div> </div> <div class="b-body open" id="qf-body-b2"> <div class="qf-warn-box"> <strong>&#9888; DEFLATE the air suspension system before removing the valve block.</strong> The air suspension lines operate at pressures up to 10&#8211;15 bar. Disconnecting air lines from the valve block without first depressurising the system causes sudden, violent release of compressed air, which can cause injury, damage the VOSS push-fit fittings, and propel disconnected lines. On Tesla Model S and X, use the Tesla Toolbox service routine <strong>PROC_TAS_X_DEFLATE</strong> to fully vent the air suspension before disconnecting any pneumatic line or removing the valve block. </div> <div class="qf-symptom"><strong>Air suspension warning message on the touchscreen &#8212; system unable to reach or maintain target ride height</strong> &#8212; The most common presentation of valve block failure. The SCM monitors air spring pressure at each corner &#8212; when a corner cannot be raised to its target height within the time limit, or when it loses pressure while stationary, the SCM logs a suspension fault and displays a warning. Use Tesla Toolbox (or a compatible third-party tool with Tesla SCM access) to read the active fault codes before condemning the valve block &#8212; the same symptoms are produced by a leaking air spring, a failed compressor, or a broken air line.</div> <div class="qf-symptom"><strong>Vehicle sitting low on one or more corners after overnight parking &#8212; valve block solenoid O-ring leak or air spring leak</strong> &#8212; When a valve block O-ring fails, air bypasses through the degraded seal even when the solenoid is commanded closed. The affected corner deflates slowly while the vehicle is parked. To isolate the valve block from an air spring leak: after confirming the vehicle is at normal height, apply soapy water to the valve block body and all air line connections with the system pressurised &#8212; a valve block O-ring failure typically produces bubbles at the exhaust port or at the body seams of the valve block housing.</div> <div class="qf-symptom"><strong>Air suspension compressor running continuously or cycling excessively &#8212; slow pressure leak through valve block</strong> &#8212; A slow O-ring leak forces the compressor to cycle beyond its rated duty cycle to maintain system pressure. On the Tesla Model S the compressor is located adjacent to the valve block in the front compartment &#8212; if the compressor motor can be heard running at unusually short intervals during normal driving or stationary parking, a slow system leak is present. A compressor that has been overworked from a prolonged valve block leak may have accumulated thermal damage to its motor windings &#8212; inspect the compressor simultaneously.</div> <div class="qf-symptom"><strong>Specific corner does not respond to ride height adjustment commands &#8212; individual solenoid failure</strong> &#8212; An individual solenoid winding can fail open-circuit (solenoid never opens, corner stuck at whatever pressure is currently present) or short-circuit (solenoid stays open, corner vents). The SCM logs the specific solenoid fault by corner position. Confirm the electrical fault by measuring solenoid resistance at the valve block connector &#8212; each solenoid should read approximately 10&#8211;30 ohms; an open circuit or zero ohms confirms a winding failure requiring valve block replacement.</div> <div class="qf-symptom"><strong>Audible hissing from the front suspension compartment at rest &#8212; exhaust valve or O-ring leak</strong> &#8212; An exhaust solenoid that does not fully close after a height adjustment allows continuous slow air loss from the system. A hiss audible when the vehicle is stationary in a quiet environment, coming from the front compartment area, indicates either the exhaust solenoid is stuck open or the O-ring at the exhaust port has degraded. This fault progressively depletes the suspension reservoir pressure and eventually drops the vehicle to bump stop height.</div> </div> </div> </div> <!-- BLOCK 3: LOGISTICS --> <div class="qf-block"> <div class="b-section"> <div class="b-header" onclick="qfToggle('b3')"> <div class="b-title">Logistics &amp; Customs</div> <div class="b-chevron open" id="qf-chevron-b3">&#9650;</div> </div> <div class="b-body open" id="qf-body-b3"> <table class="qf-logistics-table"> <tr><td>International HS Code</td><td>8481.20</td></tr> <tr><td>EAEU Customs Code (TN VED)</td><td>8481 20 000 9</td></tr> <tr><td>Weight</td><td>~0.6 kg</td></tr> <tr><td>Country of Manufacture</td><td>China</td></tr> <tr><td>Working medium</td><td>Compressed air (dry, filtered)</td></tr> <tr><td>Operating pressure</td><td>Up to 10&#8211;15 bar (air suspension circuit)</td></tr> <tr><td>Packaging</td><td>Individual protective packaging</td></tr> </table> <p style="font-size:12px;color:#888;margin-top:12px;font-style:italic">Air suspension solenoid valve blocks are classified under HS 8481.20 as valves for pneumatic transmission of power.

RAPA supplied the same physical valve block assembly to multiple OEM customers &#8212; Tesla, Volkswagen Group (Touareg, Phaeton, Q7), and Porsche (Cayenne) &#8212; as part of their air suspension system packages. Each OEM assigned their own internal part number to the assembly, but the physical component is identical or nearly identical across all applications. This is confirmed by the fact that the ok.parts family contains 26 cross-references spanning all these brands. For a distributor, the cross-platform compatibility dramatically increases the sales base for a single stocked part number.</div> </div> <div class="qf-faq-item"> <div class="qf-faq-q"><span class="qf-faq-q-icon">Q</span>Can the valve block be rebuilt with an O-ring kit rather than being replaced?</div> <div class="qf-faq-a">Yes. Aftermarket repair kits containing the internal O-rings and seals for the 600640600A valve block are available from suppliers including Arnott and specialist air suspension rebuilders. O-ring repair is appropriate where the valve block body casting and solenoid windings are confirmed serviceable and only the sealing O-rings have degraded. The repair procedure requires complete disassembly of the valve block housing, O-ring replacement, and reassembly with correct torque on the solenoid retaining screws. A repair kit is significantly lower cost than full valve block replacement and produces equivalent service life if the solenoid windings are undamaged. Where solenoid winding failure is the root cause &#8212; confirmed by resistance measurement &#8212; repair is not possible and full replacement is required.</div> </div> <div class="qf-faq-item"> <div class="qf-faq-q"><span class="qf-faq-q-icon">Q</span>Does the replacement valve block require suspension calibration or SCM coding after installation?</div> <div class="qf-faq-a">On the Tesla Model S and X, a suspension inflation and normalisation routine must be completed after valve block replacement using Tesla Toolbox (PROC_TAS_X_ENTER-NORMAL-MODE). This routine pressurises each air spring to the target level and confirms the system is responding correctly to the SCM commands. Full system calibration is not required for the valve block itself &#8212; the SCM does not need to be coded to a replacement valve block. The ride height sensors retain their calibration values. However, any suspension fault codes stored during the period of valve block failure must be cleared after the repair, and the vehicle should be driven on a level surface to confirm stable ride height at all four corners before the fault codes are permanently cleared.</div> </div> <div class="qf-faq-item"> <div class="qf-faq-q"><span class="qf-faq-q-icon">Q</span>Is white-label or custom branded packaging available for wholesale orders?</div> <div class="qf-faq-a">Yes. ok.parts supplies directly from the manufacturing facility and can accommodate neutral white-label packaging or branded packaging with your company logo, part numbers, and barcodes.

A valve block that has leaked for an extended period forces the compressor to run beyond its rated duty cycle, overheating the motor windings. If the compressor has been running abnormally frequently before the valve block fault was diagnosed, inspect the compressor motor for overheating signs and measure motor winding resistance. A compressor that has been heat-damaged will fail within weeks of a valve block replacement &#8212; replacing both during the same service access is significantly more cost-effective than two separate repair visits.</td> </tr> <tr> <td>Air Suspension Desiccant Filter / Dryer</td> <td>Air suspension compressor dryer cartridge &#8212; confirm by platform</td> <td>The primary cause of valve block O-ring degradation is moisture entering the air circuit through a depleted desiccant filter. The desiccant filter is located in the air compressor assembly and absorbs moisture from atmospheric air before it enters the compression circuit. A depleted desiccant passes moisture into the compressed air, which condenses in the valve block and attacks the solenoid O-rings and metal components. Replacing the desiccant filter simultaneously with the valve block removes the moisture source and prevents early re-failure of the new valve block. The desiccant cartridge is low-cost and easily replaced with the compressor assembly already accessed for valve block removal.</td> </tr> <tr> <td>VOSS Push-Fit Air Line Collet Set (x7)</td> <td>VOSS collets &#8212; 4 mm and 6 mm sizes as required by valve block port layout</td> <td>All seven VOSS push-fit collets at the valve block air line connections are single-use components that must be discarded when the air lines are released during valve block removal. Reusing a collet that has been released will not achieve a gas-tight seal under the 10&#8211;15 bar operating pressure of the air suspension circuit. A full set of seven new collets must be available before beginning the valve block replacement &#8212; supply a collet set with every valve block order to ensure the installer has all required components for a complete, leak-free repair without waiting for a separate parts delivery.</td> </tr> </tbody> </table> </div> </div> </div> </div> <script> function qfToggle(id){ document.getElementById('qf-body-'+id).classList.toggle('open'); document.getElementById('qf-chevron-'+id).classList.toggle('open'); } </script>
