Good evening, do I come with a Nissan Primera P12 Traveller 1.8 petroler over the TÜV despite engine warning light with the error message: Lambda probe measures wrong values? Actually, the exhaust gas values are in the green area. Now, however, I have read that under certain conditions at HU the actual values are not measured, but the on-board computer is surveyed. And if this indicates an error in the exhaust gas recovery, no new TÜV is to be expected. ? Bzw when is actually measured and when are they only read out? Mfg, Mike
