Other things I could try? Yes another stupid boost error
« on: 25 February 2013, 13:26 »
Hey guys,

Since owning my golf in April I have solved and fixed a number of error codes but the one bastard code that sits there laughing at me is that stupid "boost loss between Turbo and DV!" Think its 1705?

So far I have done the following.....
  • changed all boost pipes to silicones.
  • changed standard DV to a forge 007p.
  • changed charge pipe to AGU one.
  • full TB clean.
  • two services.
  • oil pickup pipe changed.

I cleared the code and drove for a week and hey presto it's back!  :sad:
I also have a new south boost gauge installed and I'm getting around 5 psi and its holding fine.

Before I pay for a smoke test is there anything else I could try?

5psi holding or 5psi full on wellies? i get it leveled at 0 when going from A-B but thats for fuel reasons when i floor it it holds at about 10 or just under until i hit a cruising speed then melows to between 5 and 10 (I like to cruise a bit faster than most) but if im going 70 its between 0 and 5, im telling you mate get that PVC system yanked out as well as N249 delete and carbon canister, that way you've ruled out a couple of issues really

Has your DV got the correct spring in it?

is the fault code 17705 and has it been remapped previously?

5psi sounds like limp mode boost levels

it could be an issue with a remap or even the stock map that causes a 17705 even though there is no leaks or problems with the car

Is the TIP silicone?

Have you checked the lowest connection on the TIP, from memory that goes into the PCV system

not sure of this is relevant to you but a guy over at ukmkivs had success replacing his rocker cover gasket. He found it was leaking and causing surging and juddering problems. Not sure of your suffering from that or if its just limp mode your getting. Im having the same issue so im gonna do it just to rule it out. Like you ive done the agu chargepipe which i thought was gonna fix the 17705 code, next up is the catch can and an n249 bypass and probably an sai removal.

check the lowest connection on the TIP, bet the pipe is split or the TIP is

you have changed the boost pipes but have you checked the pcv system itself as thats usually where the split leaking pipes are and not the boost pipes themselves  :wink:
