High-quality Injector Locking Cap 059 103 113 for Imported Audi Q7

This OEM-standard injector locking sealing cap with OE number 059 103 113 (updated replacement part 059103113G) is an important sealing wearing part applicable to imported Audi Q7 fitted with 3.0 TDI V6 diesel engine. The product enjoys steady sales volume and continuous repurchase orders in the global auto aftermarket. It is widely stocked by professional VAG repair shops and cross-border auto parts wholesalers, and supports one-stop combined ordering with injector repair kits and cylinder head service parts.

Core Selling Points

Cost-effective sealing accessory for centralized one-stop purchasing

Mounted on the top of cylinder head fuel injectors, the locking cap is exposed to long-term high temperature from the cylinder head, diesel corrosion and persistent engine vibration. The built-in rubber seal will gradually harden, age and lose sealing elasticity after long-term operation.

Failed locking caps will result in diesel leakage around injectors, heavy carbon deposition, rough idle vibration, tough cold start and black exhaust smoke during acceleration. Most buyers place bulk orders together with injector copper washers, valve cover gaskets and PCV valves to cut purchasing and freight expenses, bringing stable profit margins and low inventory pressure for sellers all year round.

100% OEM dimension matching, direct installation with no modification required

Manufactured strictly following Volkswagen official technical standards. The overall shape, mounting hole spacing, central hole diameter and sealing surface radian are fully consistent with original 059103113, and the upgraded OEM number is 059103113G.

No cutting, grinding or extra processing is needed during replacement. It locks firmly on the upper position of 3.0TDI injectors on Q7 cylinder head, perfectly matching the original assembly structure and greatly shortening maintenance working hours.

Applicable Vehicles & Engines

  • Matching engine: 3.0 TDI V6 common rail diesel engine (engine code: CATA, CRC, CRCA)
  • Main applicable vehicle: Imported Audi Q7 4L chassis (2009–2015)
  • Compatible models: VW Touareg, Audi A6 C6/C7, A8 D4 equipped with the same 3.0TDI power unit
  • Installation position: Fastening and sealing component on the top fixing end of cylinder head fuel injectors

Optimized Durability Structure

  1. High-strength stamping steel body: Excellent structural toughness, free from thermal deformation under long-time high temperature conditions
  2. Integrated high-temperature fluororubber seal: Great compression resilience, oil resistant and anti-aging to effectively prevent diesel seepage
  3. Precision positioning holes: Align perfectly with original bolts for even stress distribution after tightening
  4. Anti-rust surface treatment: Resist corrosion from engine bay oil mist and diesel liquid
  5. Finished product with integrated sealing structure, ready for direct installation

Core Functions & Engine Protection

  1. Secure and lock fuel injectors to prevent displacement and loosening caused by engine vibration
  2. Form effective sealing on the upper installation position of injectors to stop diesel leakage and blow-by gas escape
  3. Reduce carbon dirt accumulation around injector holes to maintain a clean working environment for injectors
  4. Stabilize fuel injection status and ensure normal combustion of each cylinder of the diesel engine

Malfunctions That Can Be Fixed

  • Diesel seepage and oil marks around cylinder head injectors
  • Unstable idle speed and obvious engine shudder
  • Hard cold start with long cranking time before ignition
  • Thick black exhaust smoke during rapid acceleration
  • Excessive carbon buildup on injector surface worsening fuel atomization performance

Factory Testing & Stable Inventory Supply

Every locking cap is inspected via compression sealing test, high & low temperature cycle aging test, salt spray corrosion resistance test and vibration fatigue test before delivery, meeting IATF 16949 automotive industry quality standards.

Ample stock supports mixed ordering with injector seals, valve cover assemblies and complete 3.0TDI engine overhaul kits. Neutral package and private label OEM customization services are available for global wholesale clients.
