Moin, we have the problem that the previous owner of our 850 2.5 petrol engine said smart as he is to retrofit an immobilizer himself and since then the car has repeatedly the problem that after starting some lights in the speedometer do not work and also light, turn signal ect. does not go. Now the car has such a small box with a small socket key. Now my question: Can you possibly bridge the immobilizer that you no longer need the key for it?

Hello together, the car has not been so long. I found today that the climate compressor in the switched on condition about every 3-5 seconds on and off. The previous owner told me he was about 9 months ago at the climate service. This cycle would speak for too little refrigerant. What is the best procedure? Should I first have the climate filled again to make sure that it is really full? Have now briefly on the valve to the On the other hand, I had a few drops of greenish oily liquid under the cooler after the transfer in the front? But not since then. I checked everything with a black light flashlight, didn’t discover anything. The cooler fan does not run, even though the climate is switched on. Or does it come after a certain time, because I always have the climate stand for a short time. If the engine runs longer and is straightened in the idle g warm, the fan is already on, even if the climate is off. How should I best proceed? Greetings Horst

Hello, with which readout device can I read the engine with one of the last V70 I Built 99/00 with Denso? Thank you

Hello, I can’t get any further with this OBD2 story. Now I have found out that for my elk (860 10V 144PS BJ.96 petrol / ID: YV1LW5102V2285636) pin7 plugs have to be rerouted to PIN3 socket to read out the moto control unit – ‘Fenix 5.2 (10V suction cup 22-99)’. Also for climate ECU and cruise control. In addition, PIN16 and PIN5 should be connected to each other (plug / jack). Couldn’t I just connect PIN3 and PIN7 in the K409 plug with a small switch. Wouldn’t it make things easier? Or could something go wrong, and I can only connect the 3 PINs with cables (plug / socket)? And is my research even true? Greetings, Jürgen

Hello together Unfortunately, the search function could not help me this time. So here’s my first post, or my first question: I recently imported a T5-R from England. This has a mph cluster instrument installed, which I would like to replace with a kmh instrument. As soon as I connect the kmh instrument, the speed indicator does not work. Moreover, the flashing of the correct mileage does not work either. Now I have two questions: 1) Does something have to be reprogrammed to make the 850er think again in km/h? 2) Is the mileage in the control unit of the car, or in the instrument cluster? Would it be stupid if I just read out the mileage from the combination unit. Thank you very much for your help.

Hello, I’ve already been looking “passive” for the problem and also found clues to solutions. My problem (Volvo V70 XC 2.4 Turbo 193 ps, BJ 2000, KM 162.000): Engine light burns, engine jerks when accelerating, especially from approx. 2000 rpm. It does not bring full power I have exchanged: – TCV – spark plugs (against original Volvo) – petrol pressure sensor After swap TCV it was gone – Turbo has also “pitched”. Since the engine light still burned, I once stuck off battery overnight I switched spark plugs and petrol pressure sensor. No change. Now I was reading out at Volvo error. A lot came out: – ECM-2810 Front heated Lambda probe group 1 – signal too low – ECM-2A0A Rear heated Lambda probe group 1 – signal too low – ECM-2A2A Rear heated Lambda probe group 1 – signal too low – ECM- 4000 Activated carbon filter valve – signal too low – ECM 6800 Turbocharger control valve – signal to ni edrig (actually already exchanged?) – ECM 9300 Clutch pedal positioner – Incorrect signal (tempomat does not work – therefore probably) My question – before I go into the long search: Does anyone know if the fault codes Lambda/Active carbon filter flush valve/turbo loader control valve can be connected, i.e. the cable strands together or on a fuse? It is strange that the TCV has been changed but should already be defective again. Thanks for your help e! Greetings Peter

Hello, I installed on my 99th TDI 2 years ago the full impact limiters, which are in the part program for my SMI steering gear. I think the plastic discs were black. Somewhere between the lines here in the forum I read something about (meaning) “…the thinner blue (?) steering stop limiters are sufficient for maturation. I drive 205/50 R16 or in winter 205/55 R16 and have mounted 5 mm track width at the front of each side. The big turning circle is annoying. Are there thinner discs than the black ones with the above mentioned part number? -Did the track width have a positive influence? -Couldn’t it be, though? Grinding should not be. When buying the car, the wheelhouse shells were ground through and the sheet on the longitudinal beam blank. The previous owner had also driven 16” times. I painted it. and other wheelhouse shells installed. Greetings Chris

Hello! does one of you sometimes have the message “No Chngr” after starting the FZG or after switching on the ignition? This happens quite often with me. After that I have to switch to radio or another input and then back to the Yatour, after which it works again. Can you fix it somehow? Thanks

Hello, with my Volvo V70, Built. 99, the engine control light has been shining permanently for a few days. When reading out the fault memory, the device says that the clutch pedal sensor is defective. Can this cause the engine control light to glow? And can you change the sensor yourself?

Hello! The blower engine has given up its mind from one day to the other. First the speed was fluctuating…it drove up and down, although fully turned up and at the end of the ride there was nothing to hear. There were also clear vibrations in/under the glove compartment. I already know how to exchange it. Are there special recommendations for replacement? The original is quite expensive…
