MAF Sensor Fault

[Luni9901]

Hello I have a Citroen Grand C4 Picasso been in and out of garage several times with EML light on with MAF sensor fault I have so far had the MAF sensor replaced the EGR valve replaced and filter but still getting the error code anyone got any suggestions on what else to look for as will be going back to the garage for a 4th time it seems to fix it.

Welcome along.

What engine is in it? What code is actually throwing? Has the inlet been smoke tested?

Hi the code its throwing is P0102 low airflow its a 1.6 diesel I dont think they have smoke tested as far as I am aware.

Bit frustrating as I am 620 down with the garage already and they still have not fixed the problem

This link has a list of possible things to check including air leaks, wiring and the MAP sensor and looking at live data - presumably the garage would have done these checks ? https://www.obd-codes.com/p0102

I would hope soo I mean the garage it is supposed to be with is a Citroen specialist I will take back in and get them to check again starting to lose my patience with them though might have to take it to the dealership failing that and hope they can sort it
