Hello dear elk-lovers, first of all a friendly HALLO here in the forum! After a free master workshop has screwed around and doesn’t know any more, I took care of the 850s from my buddy. The error: The engine simply goes off completely sporatically and then does not start again. The next day he goes on tatellos again. Error code is not stored except the Lambda, which shines for several years. The stored error code is the 0103. If I The lamp also goes off and goes on again after a few minutes. What has been done so far: In the workshop: spark plugs and distributor cap changed, ignition cable tested. The master said that then the cylinders are full of gasoline… I: -Very much here in the forum gemökert! 😉 -petrol pump relays I soldered – without success -new petrol pump relay from SCANDIX pure – without success -Then found, the relay expand and bridge the contacts, petrol pump runs (naturally -Crankshaft sensor replaced – without success -now the air mass meter, which is installed in the housing of the air filter box and is pig-priced, exchanged – without success However, I found out that if it has gone out and I pull off the plug on the air mass meter, it immediately starts up again. Then the error code 0123 is stored (only with pulled plugs). Without this plug it seems to run forever! Think Now I have seen that there is also a sensor on the front (if you are standing in front) of the throttle valve housing. Is that the throttle valve sensor and could that be the culprit? I have to admit that I have slowly run out of ideas but I have licked blood and want to let the moose jump again. Another expensive workshop visit at a Volvo workshop is of course the last option, since the GOOD already galloped 340.000 km d Bj 96 is. Oh yes, the 850er has the ODB II under the coin box before the switch lever… Does anyone have another idea? I am grateful for every hint! Thank you very much in advance!
