Hello All,
Looking for some assistance with the following codes. They may not all relate to the EPC light being on, but I would like to resolve the light related things first.

System description: 1.8L R4/5VT G
Software number: 4B0906018CM
Software version: 0010
Hardware number: 8E0909018
Coding: 0016551

Trouble codes:
P0322 - Ign./Distributor Eng.Speed Inp.Circ. No Signal No signal/communication
Intermittent
P0300 - Random/Multiple Cylinder Misfire Detected Implausible signal
Intermittent
P1114 - Bank 1, sensor 2 Internal resistance too high Implausible signal
Intermittent
P0304 - Cyl.4 Misfire Detected Implausible signal
Intermittent
P0140 - O2 Sensor Circ.,Bank1-Sensor2 No Activity Detected No signal/communication
Intermittent
P1479 - Brake vacuum system mechanical malfunction Implausible signal
static
P1556 - Charge press. ctrl. Value below lower control limit Lower limit not reached
Intermittent
P1327 - Knock control cylinder 3 Control limit reached Upper limit exceeded
Intermittent
P1328 - Knock control cylinder 4 Control limit reached Upper limit exceeded
Intermittent
P0012 - A Camshaft Position (Bank1) Timing over-retarded Upper limit exceeded
Intermittent
P1250 - Fuel level too low Implausible signal
static

Any help and guidance would be greatly appreciated.

Leaning towards replacing Crankcase Position Senor (G28) to clear the first one.

When was the last time you scanned for codes? Some of those may be old stored codes.

What are your symptoms?

 

[miles2go]

This scan was taken about 2 weeks ago, when the EPC light came on and the car shut off. Here is my scan from today:

Do you think I should clear all codes? I currently don't have a check engine light or EPC light on.

 

[VAGguy]

Yes. That is what i was going to suggest.

Any current symptoms?

 

[miles2go]

Lack of power and periodic hard starts accompanied by EPC light, and periodic EPC and stall when slowing to a stop.

 

[PZ]

Those are typical issues with a failing engine speed sensor.

Replaced the crankshaft position sensor, but while doing so, broke the t fitting for the vacumn lines under manifold 🤐. I assume it's just a normal t. What is the best way to get the remnants out of the tubing? Any idea what size t i should get?

All 3 legs of the t are broken

You can try a wood or sheet metal screw to get the broken plastic tube out of the hose. Most auto parts stores will carry a package of plastic fittings. I know AutoZone has one that worked.
You would need about a 3.5mm fitting.
If the plastic tube doesn't come out with a screw inside, you can just crush it with pliers and pull out the broken pieces.

Great suggestion. I ended up just replacing the connected hoses with 5/16 ID heater hose and advance auto had the tee. Everything back together and took a drive to Maryland (60 miles round-trip). Ran ok, but still lack of power, in my opinion, particularly at wot. Will look to do a smoke test and look to the turbo next. Thanks for all the assistance. I'll be back with another thread 🤪

 

[miles2go2001]

The tee I used was 5/16 all the way around.

 

[miles2go2001]

Got 24+ mpg on my little trip.

 

[miles2go2001]

Oh, I cleaned my TB while at it. Should the butterfly be stiff to open with your fingers?

 

[PZ]

Yes

Hi. After cleaning TB try to reset it, adaptation, using VAG Com, VCDS ... The usual...I bet it was great news to find out that it was just a crankshaft sensor
