CEL after a service

I did the 40k service two days ago

Oil
Fuel, air, cabin filters
Spark plugs

Was fine for a drive yesterday

Check engine light today.

No roughness.
No power loss noticed
No Symptoms at all.

Ideas?

Check coil connections, but that would likely cause a misfire and drive-ability.

Anyway to scan the code? Really, it could be anything and just a coincidence you just did the service.

CEL went out tonight as I was on my way to the store. So I borrowed a scanner and checked.

P0089
Fuel Pressure Regulator

I'm guessing a bit of air in the line from the fuel filter swap? Regardless. Cleared it and will hope it was a fluke. Obviously if it repeats the car will go in.

What kind of scanner did you use to read these codes?

I would highly suggest investing in VAG COM to any VAG owner. Keep us posted.

Some generic thing at the store. I'm not real familiar with vag com. How much is it? Just VW and audi functions?
Regarding the light, was involved in an accident and the light came on at the scene. So it'll be going to vw after the shop for that and an alignment.

I see, a lot of the codes are VAG specific so it would make sense if the code was inaccurate. Check out the Ross-Tech website for pricing, I cant remember what the cost is now.

Bring it to the dealer you need a new fuel pump/fuel pressure reg.

You've had this problem? Is the pump with the pressure reg. or are those separate parts? I read another thread about people out of warranty contacting VW to cover the fuel pump, would that make sense?

I also noticed a clicking sound randomly.

Two visits later it's solved but not anything simple. They couldn't figure it out and called VW corp for help. Determined they needed to change the fuel pressure sensor. 350$. Then on the way home from the dealer light was back on. So scheduled another visit. While in today they figured out the fuel filter was incorrect. Wrong pressure. A 4 bar. $100 for the right 6 bar (I think it was)

So here's what's under my skin. I ordered all the stuff for my little service from ESC. I put in my car and bought the appropriate parts. So apparently the part they have listed for the car is incorrect and caused this whole fiasco. I want to get in touch with them and go over this. It pretty bad when a place like that botches this. And now the root of $450 of work!
