First, thank you for all your posts on the subject of solenoid issues for the 09A. I got a call from my wife on her way to work that the check engine light came on and the car was shifting hard (2002 Jetta 1.8T). I checked the engine code with a standard scanner and found a P0748 code which translates to a Pressure Control Solenoid. Short story is with your info here I might avoid an auto repair bill and I thank you for it.
Quick question, is doing the resistance check all that's required to isolate which out of the 9 solenoids might be faulty? If so, is the resistance measured accross the ground pin in the connector and the solenoid pin of interest? Seems like it would be so but I figured I'd double check. EDIT: oh I see, the bridge column tells you which pins to bridge across to measure the resistance.
Intuitively I'd think the pressure control solenoid could be any of the pressure modulation solenoids above, but that's just a hunch.
Also, other than getting access to the solenoids themselves. Is replacing them just a simple matter of pulling them out and popping them back in? From your pics on another thread it looks like they have rubber orings on them which makes me think they pop in (similar to old school injectors).
heh, I have the Bentley for my mk2 GTI but not for my wifes 02 Jetta. Its thread like this that really save us.
