Drop in Turbo pressure 17705

[Joewb84]

Hey Guys,

I have a fault code reader and I am getting the code 17705 when I check it.  I have checked all of the hoses that I can see and can't see any obvious splits.  I understand it is common for the standard Bosch DV to fail. I eventually want to get a remap done and was going to change to the Forge DV and figured I would do this now and see if it gets rid of the fault.

Does anyone know of a good website or garage / shop in the Bromley (Kent) area that I can get the Forge from?  The ones I can find all seem to be £100+ for the part alone.

Cheers,
Joe

It could also be a software bug in the oem mapping. The early 2000-2001 AUM had this bug.

For the 007p you can try one of the forum sponsors  http://www.midlandvw.co.uk/forge_motorsport.html

They might do deals for the forum..

Thanks for the reply. Mines a 52 plate. Those links look useful.

I have found a place locally to fit a Forge recirc valve on Saturday.  Hopefuly this will sort the fault.  Fingers crossed!

Got a Forge recirc valve fitted at Sanspeed in Bexleyheath for £80.  I've erased the fault code and will see if it comes back.  If it does I will get a smoke test carried out and probably get the software update as well.

When found in the NAR (North American Region) 2.0T (BPY) check RVUTB: 01-09-03 or 2018919 for updated Crankcase Breather Valve.
If the breather valve is faulty, full engine vacuum is typically found when removing the oil cap at idle.
