X AUTOHAUX Fuel Injector Seal Repair Kit for VW & Audi — 4-piece OEM-style O-Rings 06H998907A

Comprehensive 4-piece fuel injector seal repair kit from X AUTOHAUX replaces worn injector O-rings and pintle caps to restore proper sealing on compatible VW and Audi engines.

This X AUTOHAUX kit contains the upper and lower injector seals, installation caps, and retaining pintle caps designed to match factory fitment for several Volkswagen and Audi models. It’s intended as a preventive or corrective maintenance set for fuel injector sealing points that can leak, cause fuel odors, or contribute to poor engine performance. The kit includes part numbers commonly referenced for replacement—such as 06H998907A, 06J998907A, and 06G998907—so you can verify compatibility with your vehicle before ordering.

How will this kit affect drivability when injector seals leak?

Leaking injector seals can let fuel collect in the intake or cause fuel to escape around the injector, which may produce rough idle, fuel smell, or harder hot starts. Replacing seals restores the intended fuel containment and reduces the risk of fuel dilution in the oil.

• Restores proper sealing at the injector mounting point to prevent fuel seepage.
• Can reduce rough idle and decrease fuel-related odors in the cabin.
• Helps prevent fuel from washing oil and thinning it over time.

Which vehicles and part numbers does this set fit?

The X AUTOHAUX kit is made to match OEM-style seals for a range of Volkswagen and Audi gasoline engines. Check your vehicle’s exact part number or cross-reference the numbers supplied in the listing before purchase to ensure correct fitment.

• Compatible part references: 06H998907A, 06H 998 907, 06G998907, 06J998907A and close variants.
• Common-fit vehicles include VW Beetle, Golf, Passat, Jetta, Tiguan, Scirocco, Sharan, Transporter, CC, and EOS.
• Audi fitments include A3, A4, S4, A5, S5, A6, S6, A8, S8, Q3, Q5 and TT (select models).

What’s included in the kit and what materials are used?

This repair kit bundles the components typically replaced during a fuel injector seal service so you don’t need to source parts individually. Components are made from durable elastomers and molded caps intended for repeated installation and resistance to heat and fuel exposure.

• 4 x injector upper O-rings and 4 x upper seals for the injector bores.
• 4 x upper retaining pintle caps, 4 x lower retaining pintle caps, and 4 x injector caps to protect tips and ease installation.
• Constructed from fuel-resistant rubber and heat-tolerant materials to minimize deformation and cracking.

How difficult is installation and what should I prepare?

Installation is intermediate level and typically requires removal of the intake manifold or rail access depending on engine layout. If you are not comfortable with fuel system work, consult a technician; otherwise, have basic hand tools, a clean workspace, and follow vehicle-specific procedures or an instructional video.

• Recommended tools: basic hand tools, torque wrench, and safety gloves for fuel handling.
• Search for vehicle-specific installation videos to follow correct order and torque specs.
• Replace seals on a cool engine and relieve fuel pressure before beginning work.

Who is this for: The X AUTOHAUX injector seal repair kit is aimed at DIY mechanics, independent shops, and fleet owners who service Volkswagen and Audi gasoline engines and need a cost-effective replacement for worn injector O-rings and pintle caps. It’s useful for anyone noticing fuel smell, rough idle, increased consumption, or who wants preventive maintenance to avoid oil dilution and more costly injector-related repairs. Always verify fitment with your vehicle’s part number and follow safe procedures when working on the fuel system.
