Throttle body in 2001 Passat

https://www.youtube.com/watch?v=Hbr77jfWwOk

Sunroof drains are a common problem on many models. Cleaning or modifying the sunroof drains usually takes care of the problem. You may resolve your problem. I believe that the trouble codes are unrelated and may need professional diagnosis as you need VAGCOM to adapt the throttle.

Has to be at a shop that works on turbos

None of the code checking etc, without vehicle
system knowledge, is of any value to you

Throttle Body is not humming

If you can buy factory manuals for lots of money,
maybe you can work on it, when you have trouble charts to follow

Throttle Plate Angle or % is subject to constant change, so unless
your friend knows the vehicle systems, then you wouldn't be here

clean throttle body,could be crankshaft sensor.

Check motor mounts, check CV joints both of thees issues can cause the engine to stutter or shake the other possibility is a fault in the overdrive system of the transmit ion
if you have overdrive . also engin idle should be about 500 to 700 rpm normal any higher will case an abruptness .

Multiple faults can cause this.

With this being an ongoing problem you need a shop to scan the systems.

EPC is the Electronic Power Control....or throttle pedal and throttle body.
When fault detected engine will only idle.

Dirty throttle body is often cause of no power or gear engagement with EPC lamp illuminated.

it can still cause trouble, im a former vw tech, and you would be amazed at how long they last or issues that arrise, I watched a tech install an engine once because he refused to belive radio was failed,

It is a shot in the dark at this point. Your Passat, like mine, is a computer on wheels. Get yourself a VAG scan tool for $50. This will allow you to plug into your car's computer, under the steering wheel, and read its functions. It is easier than Windows for a PC...very user friendly. This will tell you of any issues, even the ones that do not set off the MIL(malfunctionIndicatorLight).
You could have a pre-CAT O2 sensor sening bad readings or a bad ignition coil/wires/or plugs etc...
I do not see how a coolant temp sensor would cause those symtoms, but if the scanner says that it is not getting a signal that it can use from that sensor, then it should be replaced. The computer is smarter than the mechanic, but it can take a mechanic to interpret the codes correctly which is why you post them here. Example, a reading from an O2 sensor may mean that the fuel/air mix is off due to a bad spark plug no burning it's fuel or a dirty air filter causing MAF sensor poblems, when the wrong solution would be to replace the O2 sensor.
VW will charge you over $100 per issue. They will give you the same answer the VAG scanner. You can get OEM VW parts on-line a lot cheaper than the dealer, too.
Good Luck!

My old 1992 passat done this when the catalytic converter was faulty but have you tried cleaning the throttle throat, just remove the fat black hose and manualy holding the throat open wipe it clean with a cotton cloth with wd40 applied as oil dries in there causing a residue build up.On idle no fault codes will show with a catalytic converter and mine passed a mot.

Hi, I have a 2001 polo 1.4 mpi it lackes power when you hit a hill it just dies, It has had new cat, fuel filter, fuel pump and throttle body, but is still the same it just dose not want to give me full rev's?

what tha generally means is your o2 sensor is throwing a fault code. this is mostliely due to the fact that your TPS (throttle postion sensor) is not functioning properly. this is why there is also a rough idle to the vehicle. have the TPS replaced and the problem will be solved.
