I live in Vancouver and this is my first full winter with the car. It's a 15, 1.4T @ 45,000 KM. Last winter was mild, and barely saw anything below -2. This year I have winter tires and we've had much colder temps and that's when the CEL's came on. Went for a drive and it was -17C. Had a P0700, P069E and a P2534(high ign switch voltage). About 2 weeks ago, we had some -6 temps, and had similar. P069E but this time a P2535 (low ign switch voltage).
So what I'm really asking is there some sort of design flaw that would cause these issues? I had a scangauge 2 installed, and the dealer pointed the finger at that the first time, but the 069E is back again, and they neglected to explain why they say that the 069E was something else other than the fuel pump control module. So now I'm wondering if the fuel pump has a hard time pressurizing under cold fuel?

The first code in memory is primary. All codes following are generally resultant.....a result of the first code....so they generally are not relevant.

That being said, what is the first code that comes up?

P069E is the first one, followed by the 2435

What battery voltage are you seeing before you start the car? If it's below 11.6v your battery needs replacing. The low fuel pump voltage can be a result of a battery problem.

The first time it happened I had 069E followed by high voltage, and then it's freezing out (-16) and then had 069E followed by low voltage.

I'll check back and see what it is in the morning after it's sat all night, but tonight isn't as cold as before.

I'm thinking battery......a soft battery sets off all mannor of goofy codes.

That 11.4 business......not good.

Thanks for that. It seems to all point to the battery now. The voltage was around 13-14 while driving today, but usually that auto off alt turns on sooner, and I guess the battery finally charged, and went down to 12.5-12.7 and as soon as that happened the CEL goes off. I didn't use my gauge, but using just the dash to watch the volts, I saw 11.6 while starting. It makes sense for everything now. I was going to drop it off at the dealer, but I'm sure they'd try to point fingers at something else on the car that isn't original to the car. It stars the car fine now, I'm going to leave it until next fall, if it gets worse before then I'll replace it, but it stared with the cold so the cold will be gone soon enough.
