complete loss of boost and other weird problems

jetblackcoupe · 08-07-2014, 11:47 AM

i have a procede v5 with 9-10 maps, dci, downpipes, exhaust.

a few days ago, my car started to feel slower. more recently, during WOT at about 2k rpm, there is zero boost and the car feels really weak. i'm talking it can barely get up a hill and the rpm's take forever to climb. it happens after the first 5min of driving.

starting up the car even on cold start is fine.

i read the codes and got these:

12140 (no worries there)
11905
11906
10927

while going for a drive to replicate the codes, this picture popped up:

when i parked it in the garage, my OSS lights were flickering (first time i saw that, may or may not be relevant)

finally, when i turned the car off, it sounded like a huge fan/turbine was powering down (much louder than any normal occasion). and there was a constant squeak/creak under the hood at 1 second intervals like something was trying to start up but it couldn't.

does anyone have any experience with these strange symptoms?

This is a pb with water pump failure no?
Mee after this indication few time after indicator become red after yellow
Stop the car & water pump/termostat replacement

Looks like your water pumps taking a dump!!

Replace the tstat along with it.

would that cause all of those problems?

Yes, It would cause the car to feel weak, loss of power/boost (a protection measure), and fan would be blaring at full blast.

Check your coolant level to make sure it hasn't dropped significantly to rule out a leak (it should be fine).

Anyone know what 11905 and 11906 are?

kiteboy · 08-07-2014, 02:46 PM

My bavarian tool pro said pb water pump, in fact water pump speed 0!!!!

water pump would throw those codes?

kiteboy · 08-07-2014, 05:38 PM

I don ´t know...??? Which diag you use ?

Ingeniator · 08-07-2014, 05:49 PM

Codes are

12140 - 2F6C Exhaust flap (If you have a BT cable address to disable is 447AC set to 0)
11905 - 2E81 Electric water pump speed deviation
11906 - 2E82 Electric water pump shutdown
10927 - 2AAF fuel pump plausibility (No issue)

kiteboy · 08-07-2014, 05:59 PM
