Title: pressure drop between turbo and throttle valve (check d.v. ) P1297
Post by: brown29 on 11 September 2012, 17:37

Hi am getting the following code and my car is not running as well as it normally can:

pressure drop between turbo and throttle valve (check d.v. ) P1297

Could this be a problem with the dumpvalve or a split pipe?

How can I check these issues out?

Thanks.

Both!!!

check the seal between the pipes at the back of the engine bay - the one that connects the charge pipe to the pancake pipe its the rubber one where the 'c' clip is (look for oily residue)  :wink:

Im still trying to find the same fault on mine too, Rio, When I took that pipe off and looked at it it seemed fine but had alot of oily residue like you said to look out for, but I swear he pipe looked fine?  :huh:

Was it oily on the outside near the connection or just the inside??

Stock or tuned?

80% of the time the 17705 fault is down to a SW bug, the other 20% could boost leak, vac leak, or weak actuator.
