Hy, well, I’m not completely unnecessarily, but I’m grateful for every “sach & expert tip” right now, and just pretend to be completely stupid…. I have a V70 1 year 11/99 / Mod.00 2.4T 193PS 2WD Autom. Has BSR 3 inside. In addition, he got a replacement engine about 4 years ago, and 2 weeks before its exchange, a new Turbo and Lambdasonden ect. Everything went well until last October I hear at the TÜV, the car is top, only the exhaust values do not fit at all, everything deep in the red n = shock, which I was sure, that all fits, ran well, did no mucking and fuel consumption even less than with the original soft goods. Now the at the TÜV also had the additionally on ODB2 had and said, the Lambda probes work well, and show no error. Also I had there still no error from the MKL. I think before the engine swap, I had the old Lambda probes + old original KAT inside and when my wife drove with the car, almost every time d lit up the MKL, because the rear Lambdasonde (which drove too timidly and KAT already 280tkm on it) reported. Therefore the change from BSR Stage1 to 3, because there is the whole exhaust system together with KAT there ect. During the conversion the Lambdasonden took over and drove now 2.5 years like that. The at the TÜV said the KAT (400 Zeller) is through…. I talked to BSR, they send me a new one on Kulanz 26 months (thank you again) . This was now installed at a company (same time with decent motorsportsche) llen + the transitions that are never 100% close to a stainless steel, hidden . now absolutely dense ). Funny way I was still in the red area during the measurement, whether the original soft goods or the Stage3 had on it (with original soft goods the red area went down a bit, but also not much ). Now in the last weeks 3x the MKL light up (had I posted e here FK P1132 ). The master there looked and saw that it on the right side at the suction bridge did not light up . (Last week he got 5 new original candles + new Bosch ignition coils) Master calls me, says now it is a bit better, but still heavy in the red *kotz* He thinks the new KAT is to blame. I think the old KAT + the new KAT in the red, it can not be the KAT. The candles were white at the exchange (magic), but that means nothing, because a real candle picture you get actually only if you get the on the I think it’s very funny, that the heavy in the red area when measuring the exhaust gas, but the rear lambda probes didn’t report anything!?!? She already reported when my wife was driving….and now nothing (is already funny?). The master said the probes didn’t mean anything, he measured the resistance, everything was fine. I think also , that the fault codes to the Lambda probe (P1132) which I got 3x had to do with the false air intake at the intake bridge…, since now no Fehelr ect. anymore. So, red area in the exhaust gas measurement, means for me “too fat”. What is everything, with my motor B5244T responsible for the adjustment of the fuel quantity, i.e. which probes does he have ? Lambda probes, outside temp. feelers, and what I once heard years ago, that he also has an octane knife, depending on whether I refuel 95s or 98s, st He turns around (but I just heard it as I said). Throttle flap is good and OK, don’t twitch, not even anything. LMM I thought at the beginning, but he doesn’t run in any emergency pogram and also shows no mistake about it (though I took him out and cleaned him up. wasn’t dirty or anything). What else can there be that the one so in the red measuring range blows out ??? And at the same time “no” error message brings ??? I thought already I swap on suspected the first BOSCH Lambdasonde (rule probe), however, is no cheap attempt….and if the TÜV and the master in the workshop think the probes are ok, even such a thing !? Do you have an idea ? Thanks in advance!
