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

[brown29]

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)

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?

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

i had that on mine and it was a dirty throttle body the garage said full of carbon, they cleaned it an its been fine since.

Mostly on the inside but had done on the outside too

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.
