Hi Ron, a colleague put me onto you. Just had my mass air flow sensor changed by JE Engineering (good lads). At 177k miles - no complaints. They had to fit two though. The first was faulty. My colleague tells me that you have a more robust MAF sensor (not affected by water/moisture for example) which may be available to swap over on My Defender Td5 (2002MY). If so, can you supply/advise details please. Will I need to remap or reset the ECU if I change the MAF? Cheers, hardtop.
