High fuel dilution @ 8%. This car has a bad thermostat which I found by watching coolant temp PIDs with my Maestro equipped pioneer receiver. It was also doing excessive DPF regenerations every 180 miles. I think the excess fuel and regenerations is from the low coolant temps causing the ECU to run in open loop. This car has no stored or active codes which is rare for a VW. No other diagnostic work has been done yet.
If anybody has another theory of what is happening here, chime in. The backstory in the car is below:
I got this low mileage Jetta sportwagen in April 2020 when covid-19 was in full swing. It was really cheap, the original owner who was in his ‘80s died in 2018 and it had been sitting for about 1 year. Rodents did some damage to the wiring which was repaired by the dealership.
I bought it with 46k miles for $6800 from the attorney managing the estate. It was about 200 miles away, however I contacted him first and he held it for a few days. It is a 6 speed manual without a sunroof (VW sunroofs can have issues) which is what I was looking for. It was in VG condition with a couple body imperfections. It was a major PITA to get this thing titled in my name as the DMV was shut down.
This is the first UOA, I haven’t driven it much because I could tell it had some issues. It’s down now, getting a bunch of work done including a CR170 Turbo, sport suspension including Eibach coil-overs, new Sachs SRE clutch/timing belt/fluidamper/accessory belt/WP etc... to much to list here.
I added the lightweight wheels and Michelin Pilot Sport A/S 4 tires in 235/45R17. I also had the maestro equipped pioneer avic-w8500-Nex receiver and pioneer backup camera installed
