built with more than one injector variant. Send us your old injector’s nameplate
photo and we will confirm the match for free before you pay.

■ INSTALLATION NOTES

required after installation, following the vehicle manufacturer’s procedure

■ FAQ
Q1: Is this a genuine Delphi injector?
A: No. It is a new aftermarket injector built to OEM specification for the same
fitment. The Delphi and vehicle brand names are used only to identify the
parts it replaces.

Q2: My old injector is marked 28565335 — will this one work?
A: Yes. 28424049 and 28565335 are interchangeable references for the same
injector, together with 04B130277J and 04B130277N.

Q3: Do I need to code the injector after fitting?
A: In most cases yes — a diagnostic tool is used to write the new injector
correction values. Please follow your vehicle manufacturer’s procedure.

Q4: Can I buy 3 pcs only? My Polo 1.4 TDI is a three-cylinder.
A: Yes. We supply single pcs, 3-pc sets for 1.4 TDI and 4-pc sets for 1.6 TDI.

Q5: What is the warranty and how is a claim handled?
A: 12 months against manufacturing defects. Send us the test data and photos,
we replace or refund after confirmation. Installation damage and fuel
contamination are not covered.

Q6: Can you print our brand on the box?
A: Yes, for orders above 50 pcs we supply neutral or customized packaging.
