I have a 2021 CLA 35 and when I am at a complete stop (like at a stop light) the lb ft. fluctuates between 4-16 and horsepower reads 1. If I am in park these both read 0.
Is this normal? Drove my sisters g63 and when she’s at a stop these both also read 0 even when she is in drive.
Has anyone experienced this and/or does anyone know what the issue could be?
PS I took it to the dealer a while ago for this and they said there’s no issue… but I’m pretty sure this shouldn’t be happening.
My car, with no dash display, will read varying ftlbs all the time. Things like the alternator, AC, Catalyst heating mode and who knows what else will trigger more/less power needed from the engine to maintain idle rpm. P/N on mine seems pretty stable, for the most part, but in D I've seen it move around, even go negative. It is weird because I'd assume for those with dash displays that they would force to to read 0 simply to avoid customer questions.
So I'd consider it no surprise, and would've assumed it's normal. Hopefully others with a dash readout will chime in.
