My 638/2 – Vito 114 – V230 – from 1998/1999 has fat exhaust gas, stinks back to fuel. Candles are all 4 nice evenly deep black rusted. Since new candles are in from the day before yesterday the white steam is away from the back, or much less, it pulls again more evenly, it still stinks quite. So it becomes with AU or TÜV nothing. I now want to renew LMM and Lambdasonde. Probe was original from Bosch for 40 Euros. That can be taken one time. LMM buy is no problem – looks the same everywhere, there are from 25 eurons. BUT WH is the thing ???? On the suction tube between air filter and carburettor is a probe, which I would recognize as LMM, looks like a hot wire air flow measurement. BUT after I finally found this probe on the Internet, this is a temperature probe for the intake air, and no air mass measurement. I can’t find another probe – especially not one with a piece of pipe, as they overball to k can anyone help me ??
