    Hi all. I plugged my ELM 327 reader (running ScanTool 1.13) into my 330i earlier to check out some of the running parameters, and was surprised to see the intake temperature was 26c. This rose to 35c when I took it for a run. It was snowing and 2c at the time, so I would expect the temp reading to be more in keeping with the outside temperature.

    I thought the temp sensor on the 330i M54 engine wass integrated in the MAF... could this be a sign my MAF is knackered? I've just found a temp sensor listed on RealOEM.com (13621739510)... could this be what I need?



    Can anyone else share their intake temp please?!

    Thanks2bsure

    If it helps, BMW reckon intake air temp can be 20-30c higher than ambient on some models. That aside, yes it is part of the mass air flow meter.

    That sounds about right, check it from cold in the morning before the engine has been started, it is quite normal to see higher than ambient once the engine has warmed up.

    Yeah, checked it & it was ambient temp (intake temp, coolant temp & external temp gauge all reading 3c)
