One stop shopping Brake Vacuum Pump 03H 145 100 B for FAW Audi Q7 3.6 VR6
This heavy-duty mechanical brake booster vacuum pump with OE number 03H 145 100 B is a steady-selling brake system spare for FAW Audi Q7 4L chassis equipped with 3.6L VR6 naturally aspirated engines. It gains repeat bulk wholesale orders among domestic auto repair shops, VAG professional service garages and cross-border auto parts merchants. We provide full one-stop mixed purchasing with vacuum hoses, brake boosters, gaskets and complete brake vacuum system overhaul kits.
Standard Mechanical Vacuum Pump for Bulk Wholesale
This vane-type mechanical vacuum pump is driven directly by the engine camshaft. It generates stable negative vacuum pressure to power the brake booster, which reduces brake pedal operation force and guarantees reliable braking performance. It resists long-term high engine temperature, engine oil splash, frequent camshaft rotation friction and all-season temperature alternation.
Common aging defects of worn vacuum pumps: internal vane wear, pump housing oil leakage, vacuum pressure insufficient, sealing ring aging and cracking, abnormal buzzing running noise.
Failed vacuum pumps trigger critical driving safety risks: stiff heavy brake pedal, longer braking distance, vacuum leakage hissing noise, brake failure warning lamp pop-up and unstable brake assist function. Most wholesalers match this pump with supporting vacuum system accessories for unified bulk shipments, cutting cross-border procurement and logistics costs while maintaining stable profit all year round.
100% OEM Exact Fit, Direct Bolt-On Installation Without Modification
Manufactured strictly complying with Volkswagen Group OEM technical standards. Overall aluminum housing outline, camshaft drive spline specification, mounting flange hole spacing and vacuum outlet pipe thread size fully match genuine 03H145100B.
Cross-reference interchange OE codes: 03H145100C, 03H145100E, Porsche cross code 95511005002
Fitment restriction: Exclusively compatible with 3.6L VR6 FSI naturally aspirated engines (engine code BHK, CMTA, CHNA); not fit 3.0T supercharged, diesel and EA888 2.0T powertrains. No cutting or adapter modification required during replacement, perfectly aligns with original cylinder head mounting layout and greatly shortens brake system maintenance working hours.
Full Compatible Vehicle List
- FAW Imported Audi Q7 4L chassis (2006–2010) 3.6 FSI VR6
- Shared VR6 platform models:
- Volkswagen Touareg 7P 3.6 V6 FSI
- Volkswagen Passat CC / Phaeton 3.6 VR6
- Porsche Cayenne 9PA 3.6 VR6
Matching Powertrains
3.6L naturally aspirated VR6 FSI gasoline engine, engine code BHK, CMTA, CHNA
Installation Position
Mounted on the right side of engine cylinder head, driven by intake camshaft
Optimized Heavy-Duty Structural Design
- Integral die-cast aluminum pump housing: Light weight, high structural rigidity, resistant to high-temperature engine oil corrosion and pressure deformation
- Wear-resistant carbon fiber reinforced internal vanes: Stable vacuum generation under long-time high-speed rotation, anti-abrasion and long service cycle
- Multi-layer high-temperature fluorine rubber main sealing ring: Block engine oil seepage from pump flange surface, anti-hardening and anti-aging under 120℃+ engine working temperature
- Precision spline drive port: Perfect meshing with camshaft drive gear, no slipping to guarantee continuous vacuum output
- Standard vacuum outlet male thread joint: Tight sealed connection with original vacuum rubber hose, eliminate vacuum leakage risk
- Complete pre-assembled vacuum pump unit, matched with mounting sealing gasket for direct replacement
Core Brake System Safety Protection Functions
- Generate stable negative vacuum pressure for brake booster to lighten brake pedal pressing force and reduce driver fatigue
- Maintain sufficient vacuum reserve for multiple consecutive emergency braking operations
- Prevent vacuum loss during high-load engine acceleration to avoid sudden brake assist failure
- Isolate engine oil from vacuum pipeline to protect brake booster internal diaphragm from oil swelling damage
- Eliminate abnormal vacuum leakage noise inside engine bay, improve overall vehicle driving comfort
Common Solvable Vehicle Faults
- Extremely stiff and heavy brake pedal, requiring great force to stop vehicle
- Braking distance obviously extended under normal driving speed
- Continuous hissing vacuum leakage sound coming from cylinder head side
- Dashboard brake assist fault warning light illuminates constantly
- Abnormal buzzing mechanical noise from engine head during engine operation
- Vacuum booster diaphragm damaged caused by oil infiltration from defective pump
Brief Step-by-Step Installation Guide
Required Tools
Vehicle lift, torque wrench, socket set, new vacuum pump sealing gasket, engine oil absorbing cloth
- Park vehicle on flat ground, shut down engine and wait for full cooling to avoid scalding by hot engine parts.
- Lift vehicle and remove engine upper decorative cover to expose cylinder head vacuum pump mounting position.
- Clamp and disconnect vacuum rubber hose on pump outlet port, wipe residual engine oil with absorbent cloth.
- Loosen two fixing bolts of vacuum pump flange, pull out old vacuum pump from camshaft drive spline slowly.
- Clean cylinder head mounting surface thoroughly, remove aging sealing ring residue and accumulated sludge.
- Install brand new sealing gasket on the flange of 03H145100B vacuum pump, align drive spline with camshaft gear and push pump fully in place.
- Tighten two mounting bolts to Volkswagen specified torque value evenly, reconnect vacuum hose and lock joint clip firmly.
- Start engine and idle for 5 minutes, step brake pedal repeatedly to test pedal softness and vacuum assist effect.
- Check pump flange and vacuum hose joint carefully for oil leakage and vacuum hissing noise, complete road test to confirm brake performance fully recovered.
Strict Factory Testing & Stable Spot Supply
Every batch of brake vacuum pumps passes high-speed rotation vacuum output test, high-temperature oil immersion aging test, flange oil leakage tightness test and vane wear durability test before export shipment, fully complying with IATF 16949 international automotive quality certification standards and Audi OEM production specifications.
Adequate spot inventory supports mixed purchase with vacuum hoses, brake boosters, sealing gaskets and complete Q7 3.6 VR6 brake vacuum system service kits. Neutral export carton packaging and private label OEM customized labeling services are available for global wholesale purchasers, with 12-month factory quality warranty provided.
