Frequently Asked Questions (FAQs)

Q1: How do I check if this MAF sensor fits my vehicle?
A1: First check your vehicle’s make, model, year and engine variant (the listing covers many Citroën Berlingo/Dispatch/Synergie, Fiat Scudo/Ulysse, Lancia Zeta and Peugeot Partner/Expert/306/307/806/807 etc). Next verify the old sensor’s OEM number (e.g., 8ET009142‑101, 5WK9621, 9629471080) matches one of the replacement numbers listed. The product page lists all compatible numbers.
If you're still unsure, supply your VIN or registration to allow our team to confirm the correct part.

Q2: What are the signs that the MAF sensor needs replacement?
A2: Typical symptoms include:

• Engine idle is rough or fluctuates.

• Poor acceleration or hesitation when accelerating.

• Check Engine Light (CEL) showing codes like “airflow sensor faulty” or “MAF performance problem”.

• Erratic fuel consumption (typically higher than usual).
  Because the sensor feeds data to the ECU, each of these issues may indicate that the airflow reading is incorrect.

Q3: Is installation difficult or are there any calibration steps?
A3: Installation is relatively straightforward for someone comfortable with basic engine‑bay work:

• Disconnect the negative terminal of the battery first.

• Remove the old sensor (usually in the air‑intake duct between the air‑box and throttle).

• Fit the new sensor in the same orientation, reconnect wiring and ensure all clamps/seals are tight.

• Clear any engine fault codes via OBD after installation and test drive to verify normal behaviour.
  No specialised calibration is usually required beyond resetting the codes and allowing the engine to relearn its airflow baseline.

Q4: What warranty and shipping terms apply to this part?
A4: This MAF sensor ships from UK‑based stock with free shipping on all orders, and is backed by a standard 12‑month “worry‑free” warranty covering manufacturing defects. 
Installation must be correct and the sensor used under normal conditions to ensure warranty validity.

Q5: My vehicle is petrol/diesel – does that matter for this part?
A5: Yes — you’ll need to confirm that your engine variant uses the same airflow sensor type (5‑pin connector, correct mounting). The listing covers many diesel models (such as HDi versions) in the compatible makes.
Always verify by matching the OEM number on your existing MAF sensor. If your vehicle uses a different part number or connector type, you’ll need to source the correct sensor for your application.
