SEND HELP! Passat 206 R Line Broke Down! P15007 P15088.

[VWTDI]

Hi Guys and Girls,

This morning only a few minutes after leaveing home while waiting at a set of lights, my car just turned off. When I press the start button, it cranked for couple of seconds longer than normal before starting and idling fine. Then after around 5 seconds it will just turn off again. A message appeard on the dash about some fault in the stop start system. I did this a few times, and in the end it would start but idle very rough.

Car
2017 Passat 206 R Line
Stage one APR tune (installed about 1 month ago) - everthing else as stock.
Milage: 140k km, with new engine + turbo installed at 65k km (4 years ago).

I Scanned with Carista App and getting fault codes:
15007
15088

Anyone have any ideas? I can't find much on these codes, except from a post in an Audi forum suggesting 15007 = P0089 and 15008 = 15008A: S3 8V brake light failure resulting in low fuel pressure + misfires | Audi-Sport.net

Cheers,
Jeremy

Check your fuel pump; in that Audi thread, it turned out being a bad ground for the low-pressure fuel pump.

I would check powers and grounds at the pump controller under the back seats, that's if the B8 is similar to the older Passats.
