P0101 - Air flow meter P0404 - EGR valve?

Side coolant flange

Located at the top of intercooler. Look down behind the passenger (right) headlight.

Sounds like the immobilizer, do you have another key you can try?

Could be MAF sensor, bad turbo actuator pod, or intake blockage (coking)

Access from under the vehicle

Sounds like a loose main connector on your wire harness. I say that because u say its intermittent

Did all these problems start at the same time, or did you let them accumulate? I would start by changing the oxygen sensor.

The problem is in the high beam switch assembly which also houses your turn signals and possibly cruise control, and yes, I'm sure. There are some electrical contacts in the assembly which dis-connect the low beams when you put the high beams on. Constant use of the high beam switch will create arcing on the low beam switch which makes the contacts not conduct electricity anymore. The daytime running lights send power to the low beams on a separate circuit. .

The repair is to either replace the assembly, $300 at dealer, $100 or less do it yourself, or take the assembly apart and clean it for free. (2 hours or less)

P.S. If you own a VW, especially around model years 1999 to 2004, there is a rare but devastating problem with engine coolant being literally pumped through all electrical parts of your car.... destroying it. Repair cost = $8,000. It is called coolant migration. Check your VW right now (takes two seconds, literally), and do a two-minute procedure to fix your car to prevent the problem here: http://www.myturbodiesel.com/1000q/multi/coolant_migration.htm

sounds like needs new clutch as is slipping , no adjustment on clutch's on vehicles now , all auto adjust

run the fault codes check for problem wiring or crank/camshaft sensors

Just for giggles... inspect the brake pads. The light is designed to come on when your brake pads are getting thin as well as low fluid level and emergency brake use.

White smoke is most likely antifreeze from a leaking head or intake gasket.is the oil milky looking and over full level? Is the antifreeze milky or low or coming out the overflow tank?

Are you referring to your headlamp switch?

Probably best to have the convenience system scanned by a dealer or VW specialty shop. Sometimes a door lock mechanism fails and doesn't recognize that it's been unlocked.

Which ones, be specific.
