I really like these cars! Now that mine has 80K miles and is depreciated way down, I have the delete and tune fever. I did that with a 335d and it became a rocket. Does anybody know of shops besides Bimmerperformance in N. Carolina or Fixmyvw in Georgia who do this? I wouldn't take on the mechanical myself, beyond my pay grade.

FYI, I have a service code indicating the sensor for the blue fluid is not working, the car doesn't know how much it has. The entire tank must be replaced, not just the sensor. $1500. So, one might as well use that money for some real upgrades, eh?

I used DUDMD
The downpipe was buzzken

Dont think your issue is common, and I dont think it will continue to give issues if you fix it.

But the tune takes a lot of parts out of the equation and makes it more reliable in that sense.

All true. The past week, I've gotten the low DEF warning, 1000 miles to go before shutdown. I filled the DEF 3 days ago and the warning won't quit. I'm guessing a variation on the bad sensor problem. My backup car is a Trabant. What do I do?
