Hi, Am a new member, would appreciate any help or advice please. I have a 2018 Tipo Lounge 1.4 T-Jet 120 BHP. Only 16,000 miles. I have been getting an intermittent but recurring 'check engine' warning light on the dash. I have had it scanned each time (sorry don't know the scan numbers). Both Lambda sensors, the MAP sensor and the fuel pressure regulator have all been changed. Still no joy. Readings for the upstream Lambda sensor shows 1, the downstream shows 0 on Autel scan. I have seen on other postings for other models that the fuse for the heater could be the problem, but can't locate it. Has anyone else come across this?
