Hi all, this is my first thread here! I'm not native English speaker so I'm sorry if I get something wrong.
I've just become an owner of 2003 Omega 2,5 DTI Y25DT. I'm very happy overall but there's some stuff that needs fixing.
First (and most annoying), tacho & speedo are more often not working than they are. Other dials (temp, fuel, odometer and all MID functions are working OK). I've noticed that when they're not working, the speedo needle vibrates rapidly around 0. Sometimes they work just fine, but that's about 1 in 20 times. I've tried pushing the dashboard strongly inwards, but that didn't make any difference.
I've read here somewhere that this type of fault is often related to ABS which brings me to my second question. My ABS light never comes on but the system itself works as it should. When i stamp the brakes, I can feel it's doing its thing but the light doesn't come on. Also, when on ignition, light also doesn't light up. I suspect this to be a simple blown bulb, but since I've heard ABS and tacho & speedo faults can be connected I mentioned it just in case.
I have a few other questions regarding quite different problems so I'll post them later in some other thread. One thing at a time.
