Excessive rhythmic tensioner 'shake' could be indicative of engine imbalance...which could trace to anything from ignition/timing/detonation, weak cylinders (compression test), to a harmonic balancer or dual mass flywheel that needs replaced, bearings going out (engine internal or anything that the ...

As far as the reverse sensor function, there may be a software component involved. If the used radio came off a vehicle that did not have the reverse sensors installed they may not work properly. This might be a downloadable package that is updated/installed at a dealer/VIDA. I seem to recall the 'p...

The charge rate/voltage required by AGM batteries is a little different than for standard lead acid. Hence why (better/more expensive) newer battery chargers will either say "for AGM" or have a switch to modify the charge rate characteristics/voltage for AGM. You can put an AGM into a vehi...

I've got one of those. It works ok. Sound quality is acceptable. On my radio, HU650RDS (without the selector knob) you can only set up one folder with up to 999 song files in it. While playing, the display on the radio doesn't display the first digit on file numbers 100+. On radios with the selector...

What I was referring to as the 'socket/plug' is what you pictured. That appears to be ok as you already tried switching those L-R. The HID controllers (GDL MASTER, GDL SLAVE) are 'somewhat interchangeable' in that the controllers mounted into their plastic mounting bracket/vehicle wire harness conne...

The 2006 uses the Bosch style throttle body. You can try cleaning it, but from my experience and your description of the problem there's a good chance you'll probably end up replacing it. Either the integrated TPS is bad, or the internal mechanism that opens the throttle plate is worn out. Pressing ...

Food for thought: Don't forget fellow MVS helpers of that largely unresolved 'won't start in extreme cold weather' issue that plagues a certain small number of 5 and 6 cyl modular engines. According to a VOLVO TSB somebody traced it (most likely, not definitive IMO) to some sort of electromagnetic i...
