BMW E36 MAF fitted (£65) as the cheap £21 bought on eBay was faulty and car did not pass emission test at MOT. Passed MOT but massive flat spot 2,000-4,000 revs, car serviced, fuel changed and flushed (twice) but problem still there. Only when car back on road after 3 month light restoration was it diagnosed, fault 08 MAF. So MAF supplied was faulty when fitted, under The Consumer Act 2015 they must refund me for the faulty part purchased 5 months ago (up to 6 months in UK) yet they refuse and ignore UK law. £23 MAF fitted and car runs like a dream. Customer support a complete waste of time, small claims court next.
