    AC troubleshooting 2003 JSW

    Well, good news it's working now, got the car on the lift, checked coil (3.2 ohm) put 12V across the terminals and it engaged, checked all fuses, connectors, started it up and it works now. Bad news is that I still have no clue what caused it, intermittent fault is hard to trace, fingers crossed...

    AC troubleshooting 2003 JSW

    I mean it has pressure, can't say how much freon is in it, but was working fine all last summer, so not overfilled, and it high enough that I should get some compressor cycling, which I got none. So it's either sensors, relay, clutch, wiring or perhaps something else? Compressor is at the...

    AC troubleshooting 2003 JSW

    I'm fairly experienced, had ASE certifications at some point, AC license when R12 was impossible to get, but I have zero experience with newer cars, left the trade in 2001. 2003 Jetta Wagon, AC worked fine last year, pretty sure it was on couple weeks ago but it never really got warm outside...

    oil cap for ALH, where can I get one on a Sunday?? (in RI)

    I was crawling under, looking over, stuck a flashlight down, banged on the skid plate, nothing, looks like there is a clear path to freedom from drivers side if it bounced off transmission. It's dark and it probably rolled under a car. Looks like there is same exact one at O'Riely and they also...

    oil cap for ALH, where can I get one on a Sunday?? (in RI)

    Had one of those days, up since 6am, put in full day of work on a Saturday, another few hours taking care of things before I take off, decided to add the oil before I drive 3 hours to Maine but couldn't find any so I ran to Walmart a 9pm, apparently I removed the oil cap and left it under the...

    Gimme your high hp recipe for an ALH

    They are not stupid, cross-plane R1 has been dominating racing for a while, less peak HP but very manageable power delivery throughout.

    Help on P0128 code - Thermostat Fault

    You got to be seriously lazy to rig up a vacuum instead of just getting a drain pan... and not gonna work on the coolant anyway, when you pull the t-stat you end up with 2 large openings

    Help on P0128 code - Thermostat Fault

    You got to drain the coolant regardless, t-stat is pretty low on the block so you will spill a gallon at least trying to swap it, might as well drain it, there is a drain plug on a lower radiator hose, you can reach it from the top

    Help on P0128 code - Thermostat Fault

    Get a plastic neck too, screws just in case, ID parts has a kit. T-stat swap takes 10 minutes, draining and filling/bleeding coolant takes much longer

    Help on P0128 code - Thermostat Fault

    My thermostat failed when rubber seal fell off the plunger and got stuck in it sideways. It's recommend to replace t-stat and water pump with every timing belt. Car ran OK, but I had no heat

    Help on P0128 code - Thermostat Fault

    It may not operate at it's full potential, with gas cars it will run rich and flood, foul plugs, damage O2 sensors, but with diesel none of those are an issue, just bad heat and maybe not full power

    Help on P0128 code - Thermostat Fault

    You could have bad switch or wiring, plug in OBD2 and check what temp it's reading, it's aa different sensor from the one that goes to your dash. One way to test t-stat is to let car idle till fans come on, with TDI might take a while, note the temp, then go for a ride, if temperature drops...

    Dismal MPG

    New head 50k ago, replaced because someone broke off the glow plugs. New Belt, water pump, cam timing dead on, injection timing slightly advanced, but I have not logged it under acceleration. no compression check, but smooth idle, injectors balance looks good. Tires at 35psi, all running gear in...
