Help needed with fault code

[RabReith89]

Hey guys can anyone tell me what could be causing this fault code.

1 - Boost Pressure Control Valve (N249): Open Circuit
P1287 - 35-00 - -

Thanks Rab

Have you done all the bypass and everything.??

The N249/N112 would be the first place id be looking for split hoses etc.

 

[RabReith89]

Yea mate it has been done by the last owner, Unless the valve is fitted wrong??

 

[Reuvers]

what is the code? Because as is mentioned on here about a zillion times, is that when the valves are replaced by resistors every so often a code jumps up. Clear it and you're rid of it for x number of time again...

 

[RabReith89]

Tryed clearing it just comes right back.

Scaned it agen and the fault code am getting is P1288

Which i looked up and this is what i got.

P1288 Turbocharger bypass valve short to B+

P1288...Thought you said in your original post that it was P1287 but both them codes have nothing to do with the N249 anyway..

Had a look for you and the original code you said comes up as

P1287 Turbocharger bypass valve open. Which im sure is just a fancy way of saying your D/V may be at fault.

P1288 is Turbocharger bypass valve short to B+

Both 1288 and 1287 point towards the D/V anyway have a check of the hoses and the valve itself...try a leak test on the valve aswell.

Yea when a mate did a scan he got P1287 and am getting P1288. So its dump valve related then. Right i will give the hoses leading to the dump valve a look.

How do i leak test the dv mate??

Isnt the leak test - remove the dump vavle and block off the pipe, clear the code. If it comes back, it cant be the dump valve..

Thanks mate. Was on the phone to forge today and they said that this test does not apply to the splitter, as this dv works buy having a slight leak.

But they where really helpful and i ended up buying the cold side relcation while i was on the phone lol.

Will give this a try mate thanks.

Ah right didnt realise you had the splitter version...assumed it was the 007p as 95% of people run them.

The coldside kit should make your d/v a bit louder...Still not as loud as my turbosmart one is though..
