I was mistaken, it’s a general repair shop, not VW specific. I have not gotten the Bosch maf yet, will order it tomorrow. I’m going to call the shop tomorrow and let them know it’s worse than when I brought it in. Frustrated with the weather too because we had no snow all winter now suddenly it’s blizzard season and I just want to get this car fixed. I live on a mountain so the Beetle has to be dropped off and picked up in no snow conditions. Along with coordinating rides to do so.
Well, it’s been a chaotic week with work but I was able to pick her up again tonight. The garage replaced a cracked hose going into the throttle body and throttle body gasket. I thought he said they did the crank sensor too but my brain is shot tonight. I drove it 45 minutes down the highway and she feels like a new car. Pull into my friends driveway and check engine light came on. Scanned it and only one code for P0068. So it’s got to be that maf. I’ve carved out an hour tomorrow to catch up on things and ordering the Bosch maf will be done. I want to do a new Bosch tb but I think FCP is charging $600 plus for it. I’m two grand in for just this month let alone the $2k from last year. Yikes.

Wow thank you for that, I’m going to looking for a scan tool that can read live data. First thing I’ll do when I get it is check the wires to MAF. I’m also going to properly read through that thread in a bit.Quoting Ross Tech:
"Assuming, this test is done at or near sea-level, the peak output of the sensor in
g/s should be roughly 80% of the rated horsepower of the engine."
So, the normal 2.5L is rated @ 150 HP and 80% would need to be calculated to get a idea of what the peak output of the MAF sensor, should be.
150 X .80 = 120
horsepower X 80% = 120 grams per second maf max reading: for a 150 HP 2.5L engine.
So, you would be looking for roughly 120 g/s. with some slight variation, taking into consideration your current elevation, of where you live and the car is tested at.
Here was a troubleshooting thread, that turned into something of a marathon, we discussed maf testing but finally, found misfires, were a bad coil. (2.0L but principles are the same).
P0102 & p0411 Question 1998 Beetle 2.0
I cleaned mass air flow sensor....sai pump runs fine when I start car....I took air line off and its blowing good air. So next I tried with engine off I checked vacuum line going into combi valve and it holds a vacuum. Next I pulled air line off of pump and blew into ...combi valve was...
