A while ago I posted this thread: https://forums.audiworld.com/tt/msgs/1631256.phtml.

But to summarize: CEL came on while driving, 5 minutes later (still while driving) the ESP light came on. I checked the codes and posted them in the above thread.

Then I replaced the MAF and cleared the codes - all was well, for about a week. Then the same lights illuminated (CEL and ESP light).

So here I am again. Both lights are on. I logged my MAF readings and they stay at 0 g/sec at idle. I rev the engine at idle, and still 0 g/sec on the MAF reading. I try to clear the ESP fault, but it comes back right away. Same with the CEL. The ESP light does not come on until the CEL comes on, it won't come on by itself, they come on at the same time. There is no noticeable change in performance - it still boosts to 20 psi and holds at 17-18 psi. So my questions are:

1-Do I need a new MAF (again)?!
2-Are these MILs related? How so?
3-What is the "TDC memory" referenced by the error code below?
4-What should I do to figure out the problem?
5-How does the engine function when the MAF says no air is coming in?
6-Is it safe to drive? I mean, will I harm it if I continue to drive it?

Here are my error codes:

Engine Control Module: read TDC memory

 

I have just had the same issue last week and since my car was tuned by hpa and induktion. I went to them directly for help:

A fault was stored in the engine control module (TDC memory) when the MAF sensor threw a fault code that triggered the CEL. The code that was stored in the TDC memory would then throw the EPS light on, just to let you know that there was a fault code stored in the TDC memory.

 

Thanks! Isn't that redundant? I don't know why I need 2 lights instead of 1 lighting up.
