|  17705 - Pressure Drop between Turbo and Throttle Valve (check D.V.!)? Hi, My car's (octy 1 vRS) lit up its emissions light, when scanned with VAG com I got: 17705 - Pressure Drop between Turbo and Throttle Valve (check D.V.!) as the fault. 1. Can anyone give me advice as to how i do this, I'm a competent if basic diy mechanic but haven't worked with a turbo car before. The car has 92000 miles with a full service and cambelt 3500 miles ago. It was re-mapped about 3000 miles ago so i guess the extra boost has probably highlighted the problem. 2. If it is the dump valve is it worth replacing with a forge item or similar or will the standard one be fine? Thanks in advance, Andy |

Do a search on here for that fault code, you will find a fair few threads in the VAG-Com and Octavia sections that cover it pretty compehensively. Chances are its not the DV at all, more likely to be a split hose or leaking seal. There is one threa dcalled "where does this hose go" (or similar) that will be of interest. |
