Are you certain it's the "piston"?? The B4 "piston" is not available online as it's matched with the transmission during machining. The B4 servo piston "cover" is available for about $30 online. In many cases the piston bore has too much friction with the piston and som...

We measured for AC voltage at the battery with engine running. I can't recall the actual amount of AC we measured but it was way more than the alternator should have been producing. Because the later cars have a different alternator to pre-2004 we didn't have one on hand to swap in as a tester. Any ...

Did you mismatch cam cover from another head? This would be my first suspect. They were machined to match.

Transponder for $5 (just an example as I bought mine 2 years ago)

The smell would happen with a tank that's more than half full.

Just removed my 2001 T5 DSTC brake controller (ABS unit) and photographed the connector solder joints and the solder joints leading to the ABS pump. They definitely need a touch-up. I'm having DSTC Service Required, ABS brake failure and Brake System Failure especially on warmer days after the engin...

No there is a new protocol and software at dealers which has not been hacked and spat out by the Chinese cloners. From what I've read the new diagnostic platform is totally online but that could have been hype from over zealous dealers or Volvo corporate hoping a new breed of hackers won't clone thi...

Though wheel sensor codes can be caused by a dirty ABS sensor or as Oragex suggested, a cracked ABS ring on the CV shaft I've never had a wheel sensor code go away just by cleaning the sensor which by the way is a very easy DIY job. The earlier ABS sensors (pre 1999) were highly magnetic and picked ...
