How to Spot a Failing Injection Pump on Your Audi?

When a pump begins to degrade, your engine communicates it with clear signs. Catching these symptoms early can prevent more costly damage down the road. Look for these warning signals:

• Hard engine starts, especially after sitting overnight
• Thick smoke puffing from the exhaust during acceleration
• Noticeable drop in power when merging or climbing hills
• Irregular idle that feels like surging or stumbling
• Sudden decrease in miles per gallon without other mechanical issues

Many Audi diesel pumps reach 100,000 miles without trouble, but factors like heavy towing or infrequent oil changes can accelerate wear. Acting on these clues helps protect your turbocharger, injectors, and emissions equipment.

Select Fuel Injection Pumps That Match Your Driving Needs

Goldfarb & Associates offers three condition categories, sourced directly from a global network of partners. Specialists carefully examine every rebuilt unit for internal wear, and any part not meeting standards is set aside.

Buy Brand-New Diesel Injection Pumps

Choose a direct-from-factory pump for the longest service life. We source new units from respected manufacturers that build to Audi’s original specifications. Our new lineup is ideal for high-mileage vehicles or daily drivers you depend on every morning.

Get Inspected Rebuilt Diesel Injection Pumps

Our rebuilt pumps undergo a meticulous inspection process. Technicians from our suppliers disassemble the unit, measure internal clearances, replace seals and worn parts, then flow-test at precise pressures. While Goldfarb does not perform the actual rebuilding, our in-house quality checks guarantee each pump meets performance standards. 

Order Lightly Used Diesel Injection Pumps

These lightly used pumps suit older Audi models where peak pressure is less critical. Each used unit passes a detailed inspection checklist to verify good rebuildable condition. This option provides a budget-friendly fix for your Audi’s fuel delivery without compromising reliability.

Let Us Help You Identify The Exact Audi Injection Pump

To pick the perfect fit for your Audi’s engine, here are the details you need to be mindful of:

1. Check the Pump Tag
   Look for the stamped or etched part number on the pump body. Audi injection pump numbers often follow an eight- or nine-digit format.
2. Find Your Engine Code
   The code appears on a label inside the engine bay or on the driver’s door jamb sticker. Examples include CGLC, CFHC, BPP.
3. Use Your VIN
   Share your VIN, and our system cross-references manufacturing data to pinpoint your engine version and matching pump number.
4. Consult Our Diesel Experts
   If you still have doubts, chat live or call our experts. We’ll guide you through any part number confusion and recommend the right pump.

Frequently Asked Questions

Are your pumps genuine Audi OEM parts?

Our new pumps come from manufacturers building to Audi’s original specifications. While not stamped “Audi,” each part meets or exceeds factory requirements.

Which fuel injection pump fits a 2016 Audi A3 1.6 TDI?

For the 1.6 TDI engine, the most common pump is the Delphi 28535928N (often paired with Delphi part 28490887AL). Goldfarb stocks this as a new common-rail pump. If you prefer a remanufactured option, ask for the same Delphi part number marked “rebuilt” after Goldfarb’s in-house inspection. Always confirm your VIN or engine code with our team before ordering.

How can I confirm the correct pump if I only have my VIN?

During checkout or by contacting support, share your VIN. To match you with the right part, we decode build data such as engine code, model year, and original pump number.

Can you ship a pump quickly to my location?

Orders (not on back order) placed by 3:30 PM EST ship the same day from Rockville, MD. Standard ground shipping delivers to most U.S. addresses in 5-10 business days. Expedited shipping options are available at checkout if you need faster delivery.
