Hello together, I have problems with my 850. The engine doesn’t want to start any more, but I think it’s because of the electronics. I just get together what happened so far: – car was put in a barn over the winter, battery forgot to shut down – before turning it off it still drove in from its own drive – now in the summer battery dead, therefore car bridged – while bridging there were violent sparks of the crowd and the LiMa started to smoke when the engine was trying start – battery outside of the car charged and tried again, but everything was dead – LiMa removed, let measure –> Diodes burned through – new LiMa pure, battery jammed and see there, the interior lighting works again – ignition key turned, engine does not want to start, but starter is addressed – then again with power-powered booster tried, same result – cockpit shows nothing at all. If I set on ignition, should have some status lights on dive, but everything is dark. – fuses are all possible, at least in the fuse box in the engine compartment (there may be another one?) Does anyone have any idea how I could proceed here to narrow down the problem? Best regards Jonas

A few weeks ago, my 850er was replaced by the balancing tank, because the old one had a crack, some coolant was repeatedly pushed out of the lid of the tank. After that everything seemed fine, I reported about it … now I have problems again and despair so slowly During a drive of about 20 km on the highway the warning light for the coolant lit. After immediate control on the side strip I could not discover any loss, everything seemed All right, so that I continued the journey. Arriving at the finish line, shortly before the engine was turned off, the lamp went on again, then Qualmen, at the level of the compensation tank, came to it. I opened the bonnet and was to see that the tank was filled to the top, the coolant was pushed out. Again to the info: This is an AT engine, which I had only installed in the Volvo last year…. in the traffic jam the temperature always goes quite fast to the top n, never in the red area, before the fan jumps on. I called the “yellow man” who wanted to give me after a rather short inspection to understand that he could not discover anything that would prevent me from continuing my journey. On the trip home nothing happened, everything good… In the past days I had no problems anymore, but I was only traveling in the city. Today then, after about 20 km and back, the same problem. Just before I arrived home like the warning light, the temperature remained constant, … in the carport I ran the car to see what happened, when the fan started. As the pointer moved towards the red area, the coolant rose in the balance tank…. I expected the fan to sprang up, that it did, but only for 2-3 seconds, then it suddenly went out, the temperature continued to rise, the coolant filled almost the entire container. The fan only jumped up again when i ch the Volvo made up, because the situation became too difficult for me, clearly too late, the coolant has been squeezed out again again the ZKD defective??? Or maybe just a problem of the fan, or just a leak in the cooling circuit…. I am totally depressed and perplexed!!! In my workshop of trust I will probably not come with the Volvo any more, which is 85 km away and I doubt strongly that the Volvo will be happy about your opinions and tips…. Greetings Ela

Hello for now. I’m new here, but I’ve been reading with you for a long time. I’m driving a Volvo V70 I, BJ 1997, 2.4 106/144. As the friend, as you call it, pointed out to me that I should keep an eye on the right threshold in the height of the rear seat, I did that last weekend. I almost lost my eyes. But look for yourself. I would like to know your serious opinions on this. Is that still to be saved? In addition, the supposed third part, i.e. inside, has already set rust. A slightly more recent photo after coarse rust removal will be enough. I had not thought about it any more, but will probably come soon. Incidentally, there was still puff pastry over the hole before and would be tenderly removed with hammer and screwdriver. Thank you very much for your time and effort. Best regards Frank.

Hello together It’s about my Volvo V70 I, EZ 1997, 2.5 144 hp automatic (MKB B5252S) which in the stand as well as with partial load does not bring the complete performance and (feeling?) only runs on 4 pots. I had bought it at the beginning of the year, it still ran perfectly. First it started with jerks at the traffic light (only D & P, not in N). Smelling then it became worse, so that at some point he not only jerked in the stand but also when accelerating. I have already read all the threads on this topic (and there is a lot of of of them) and have already done all kinds of things, so far unfortunately without success. Now the ideas go out and I’m coming up and I’m not going to be able to do anything else. I’m not going to be able to do anything, but I’m not going to be able to do anything, and I’m not going to be able to do anything, so I’m not going to be able to do anything. The worst thing: we wanted to go to Spain next Sunday with it. You are my last hope. Unfortunately, it is very urgent and our holiday is in danger of falling into the water. I would like to list briefly what has been tested or replaced so far: ignition completely new: cable, candles, distributor, fingers & ignition coil –> Everything checked several times in the dark as well as with water (spray mist) – i.e. –> The candles are all deer brown, except for the 1st from the left, which was quite bright. the exchange (see injection nozzle below) now looks similar to all others. Black was or is not a candle. Coolant.-Temp. sensor: tested & i. O. Lambdasonde: tested & i. O. camshaft sensor: tested & i. O. DK incl. flame screen and all sounds cleaned – i. O. 1. injection nozzle v. left (looking from the front) replaced, because probably was no longer in order. Unfortunately also without success – runs like ever – bad! Errors were read out several times (OBD II plug however) – no errors stored overpressure hoses are all connected and sealed (tested). These can also be excluded. I still suspect that it is due to the ignition, but can not say it with certainty. The car smells like unburnt fuel. A thick mass cable from the battery to the engine block below was broken. I replaced this with a new one. Problem still exists. It may be that this means that the STG has a low pressure hose. Does anyone have another tip on what I can check or test? Thank you in advance!

hello elche wass would pass? tomorrow he gets the complete exhaust system including welded cat under it, so I think among other things also the steiergeraet in the hands….. death of my motor or more positive intervention in the motor management?? greeting from Spain

Hello everybody, after 19 years the end tube is rusted to me the last time! I am outraged! But because the flex tube is also dying and the cat already rattles I want to make everything new from front to back. The free workshop of my trust calls for the cat 500 Euro and for the end pot with pipes etc 300 Euro. Probably all original Volvo. Which other trade names can I use calmly? Greeting Sven

Hello, this is my first post here. So please be nice. I have only little screw experience but try to acquire what’s going on… My problem: A few days ago my interior fan gave up the spirit. No matter which controller setting, there is no air. However, it flashes with rec and AC switches, which indicates a mistake (start resistance too big etc.) It heats but does not help much without air that drives the heat out. My 850er has climate automation. Me in the first thought was blower engine did not work, two hours later got back into the car and it worked again. So out of sight, until two days ago. Again the same problem, nothing goes sour cold etc… Have already looked around me after a new used blower + pre-resistance (if present?). Since degrees just everything works again. And that is rather counterproductive for my error correction. What could this all be about, by any fuse or a resistance? It can’t be on the engine, because it works sporadically perfectly. Which parts can be to blame for this problem? My idea would be to change the five fuse in the engine safety box? But if it were through would actually go nothing more or?… Am with my anyway deficient Latin at the end…joy me out of ideas. Greeting, violinist

Hello, my Volvo 850 has been lighting up the ABS lamp almost all the time lately. After a few hijackings, I found out that you just have to turn off the car after the first start (with then bright ABS lamp) and start it again. Then you hear a switching process somewhere and the ABS lamp goes out and stays out. If the car stands a little longer and you start it again, then the lamp is on again. According to my information, the ECUs of this year are s not affected by the cold soldering points. But what can it be then? Does anyone have an idea? With friendly greeting A.Mausch

Hello dear Volvo drivers, and everyone else. I’m new here in the forum. Live in OWL and am 59 years old. With my V70 BJ 1998 sporadically “ABS and the ! exclamation sign” lights up since Oct. 2019. Then the speedo needle “lows down”, day kilometers and KM display are no longer visible. And I don’t see how fast I drive. At the driving characteristics nothing changes. From a free workshop the following was done: Signal performance under load measured (without Bef and)/mass connections tested/plug contacts tested by the ABS control unit. External performance from an electronics company in Düren: instrument cluster tested and board renewed/no error found. instrument cluster re-installed (8 hours!!!!!!!) then the rev indicator did not work. instrument cluster returned. board renewed! everything re-installed. invoice over 1000 Euro. And my car stood 2 months in the workshop. But the same error occurred again. I then put the car in a The following error message was read out: Error is active: ABS-0092 + ABS-0095 ECU communication. I got an estimate of almost 800 euros. One and extension take only 1-2 hours there!!! But with the statement that it is not 100 percent of this error. I don’t know how much money I should still put into my Volvo. If I knew the error will be fixed then I would be still willing to Because I want to drive the old Swedes for a long time. As I said, the mistake is only sporadic: sometimes every few minutes, sometimes for a day not at all, sometimes over 200 km long, sometimes only a few seconds. Maybe someone has had such a mistake with his Volvo. I now admit that I am absolute layman…I therefore ask for reasonably understandable explanations. I would be very pleased.

Hello, it is well known here how the BC calculates the current, average consumption and the range. With me it happens again and again that the current consumption is displayed very differently (depending on the load and driving mode), but this does not directly affect the DS consumption and the range indication. Which distance lengths are then used for the latter values? Olaf
