Hey there! This forum has been a great resource for me, so wanted to start by saying thanks. Skip the next part for the issues.
I recently acquired a '99 New Beetle TDI w/146k(now 148k). I really love this car! I am attempting to do the majority of the maintenance myself. So far I have replaced the Fuel Filter, Air Filter, Cabin Air Filter, Engine oil(Lubro Moly), and the Oil Filter. Everything was replaced with Mann parts, even put in a magnetic drain plug for the oil, as well as using diesel purge before changing the fuel filter. Also cleaned the intake using intake cleaner, and used a vacuum line to feed the rest of the can into. Been running great so far just want to do everything the right way and keep track of maintenance, so I could mod in the future. There's a couple of quirks I want to clear up.
I failed inspection for having the Check Engine Light it pulls up code P0380, the glow plugs were changed recently and the previous owner stated the mechanic couldn't figure it out. From my limited research it seems it could possibly the glow plug harness itself, harness connection, glow plugs, or something related in the glow plug system. Anyone have any experience for this? Pointers or what to look for? I saw the harness is relatively cheap but if I could avoid an unnecessary expensive that would be awesome.
My coolant light in the gauge at times blinks or flashes on and off in the blue color NOT the red color. In the manual it states blinking red is overheating. What could this be? A sensor not working? Anyone know the location of the sensor maybe what ohms or voltage its supposed to read out?
I also have the ABS light blink on and off at times, its not always but happens a few times every couple of days. The brakes seem okay I suppose. They stop slight squeel and decent stopping power. Haven't tried any high load braking yet. Bad sensor? Any way to test which one?
Also maybe this is normal thought I would ask at WOT or 80% throttle after about 3k I notice considerably more vibration than at partial throttle. Is this normal? What could it be if its not?
Thank you! Love the site and my TDI!
