LindseyNicole I have quite a few codes on my 2012 Jetta TDI. P2002, P2008, P2015, P240f ~ All of those I have a general idea of what they are and how to fix them. CODE; C0700 is one that I can't find any information about online. Does anyone know what this one is? Thanks in advance for any advice-info. #1 · Jun 11, 2022 I have quite a few codes on my 2012 Jetta TDI.

OBD-II Chassis (C) Trouble Code For Engine	Intake Valve Control Solenoid Circuit Low	Fuel Rail Pressure Sensor Circuit Malfunction	Cold Start Injector 1 Malfunction	Shift Solenoid E Performance or Stuck Off

The reason of C0700 OBD-II Engine Trouble Code is Fuel Rail Pressure Sensor Circuit Malfunction. This is out there as well also. has to do with shift solenoids... C0700 code on vehicles with electronically controlled automatic transmissions, the 3-4 shift solenoid is responsible for actuating the hydraulic circuits to activate clutches or bands that change gears inside the automatic transmission. Hope that gets you going in the right direction/s. #3 · Jun 11, 2022 Woot!! Perfect! Thank you!!! Do you happen to know what C0800 is? 🤪 #4 · Jun 12, 2022 Those are generic OBD codes that won't tell you a lot. Honestly if you plan to keep the car and diagnose issues yourself you would be much better off investing in a VW specific scanner - VCDS - which can be purchased from Ross Tech.com. At times you can find this stuff used on the forum classifieds. With just an OBD scanner you're not seeing all the information available about your TDI systems and will have a difficult time getting your car diagnosed fully.

I'm just trying to do a bit of research and troubleshooting on my own before I go. From what I was able to find online, C0800 is fuel too rich, a long side C0700 and all of the emissions codes I'm getting, I'm thinking just those two codes; C0700 and C0800 are related to the O2 sensor 1, bank 1. From what I have been reading is that it's pretty bad to drive around with a bad o2 sensor. Not only do I want to know my way around my engine, but I also have a two-year-old and need to know if driving my car is going to **** the engine up. It really is a shame because I just dropped 10k on it three months ago. . *Edit: I cleared the codes to do a regen, and the only ones that are popping back up are P2015 and P2008. Is it possible that a bad o2 sensor can throw false codes? From my understanding is that the o2 sensor is what triggers the CEL light. I may be reaching for straws or I may be right on track...Kind of hard to tell, lol. Does it take a while for codes to be thrown again or will they come back right away if it's a true issue? Maybe I should pursue an automotive tech degree instead of going to nursing school I really appreciate you responding and helping me with all this. I'm def going to get that reader when I can. #6 · Jun 12, 2022 If the problem persists then yes it will come back on. Those type of fault codes are usually not instant tho so it may take some time to see it again. Once fixed it may clear itself without a scanner but it usually takes a few cycles or x amount of miles driven. Nursing pays a LOT better. #7 · Jun 21, 2022 test #8 · Dec 1, 2023

The DTC code C0700 is a manufacturer-specific code for Volkswagen vehicles. It indicates a communication problem between the transmission control module (TCM) and the engine control module (ECM). This communication is essential for the TCM to receive the necessary engine information to control the transmission properly. #9 · Feb 15, 2024 (Edited)

The code C0700 is indeed less common than the other codes you mentioned, and it's understandable that you haven't found much information about it online. I think: Transmission-related: While the "C" prefix typically denotes chassis concerns, some sources suggest C0700 might be a transmission control module (TCM) fault code on certain Volkswagen models. Manufacturer-specific: It's also possible that C0700 is a manufacturer-specific code unique to Volkswagen or specific to your Jetta TDI model year. Insert Quotes Post Reply
