Nope... I told you to check for codes... then I told you to address them. I told you that certain diagnostic codes would cause the ECU to go into "limp mode" and YOU latched on to the code 52... Dunno what you want... if free advice isn't good enough go to the dealership.

Well, that explains a lot. The car is running in what's generally known as "limp mode"... it's a fail safe mode where the ECU, in response to certain diagnostic failures, imposes a low RPM rev limit, adds a lot of fuel and pulls spark advance.
Now, did you clear the codes after checking the first time, then take it for a drive and recheck?
You need to handle the error codes one at a time. The code 52 is rather common and is generally resolved by rewiring the sensors; see the MKIII FAQ section for a writeup on it.
24 and 31 are both AFM related codes. Inspect the harness and contacts for damage and signs of corrosion. Then reconnect and make sure the connection is solid.
After each of these you may reset the ECU and take the car for a medium distance drive and recheck for recurring codes when you get back home.
If the AFM related codes continue follow the instructions here:

Sorry for trying to save you money.
And there's not one vacuum line in the engine bay that would completely prevent the car from revving higher than 2500RPM... do you mean an intake hose was split? You know, it's not my responsibility nor that of any member here to teach you to check for every little thing; Additionally, the diagnostic codes are the first thing they're going to check for and work on at your local dealership.
Don't be such an ingrate or take your problems elsewhere. |
