Just replaced a leaky thermostat housing with the fancy cast aluminum from UroTuning - looked so pretty! It went on my 2001 MV after the old plastic one leaked for a month before I got a minute to get the job done.
Once I filled it back up with coolant, I looked over the motor for anything else going on, replaced the air filter, cleaned up the MAF, changed the oil, replaced a few vacuum hoses, brake pads, etc. Once I wrapped it all up and hopped in to start it up and all I got was a slow chug, chug, chug, chug...
Naturally, I thought maybe the battery was dying so I put it on a charger overnight despite having a good charge. Its a new battery, but you never know. Tried again the morning to the same slow turn of the motor. I checked all the electrical connections between the battery and the starter, grounds to the engine and they all looked good. So I turned to the starter thinking it was going bad. Decided to clean up the connections a bit and try again when the solenoid housing cracked offer so I put on a new starter/solenoid only to have the same slow turn.
Any suggestions? I don't have a VAG, but a common code reader isn't producing any codes - except low coolant from prior to doing the work. Your help is always welcomed!
