Error code 17608 1.8T

Sjdickso

Had no EML, but didnt think the car was holding boost found out diverter valve was shot so changed it for a updated OEM one 710N, also found a dodgey t piece with some vacuum tubing melted to seal it obviously had a boost gauge at some point so that has been removed now.

I did have a 17608 code = boost pressure control valve (N249) would that be down to the faulty diverter valve or leak with this t piece?

Or shall I look at swapping the N249 valve?

Cheers Matt.

It's looking like it could have been the knacked diverter valve or dodgey t piece.

I have just ordered a cheap 16Pin to USB lead and will try VCDS in shareware mode to see if the fault is back.

We just got the full version of VCDS with legit cable in work si... what a brilliant bit of kit it is....

Yeah it does look good, if it word well I may pay for the full lite version, although the full version with correct lead that has built in dongle for licensing is spot on for the money.

Do you think it could just be the valve Daz?

Daz

I'd say more the t-peice , as if the vac unit isnt getting the correct vac goin thru it , it wont work correctly.. thats for the code you have, but lack of holding boost could be down to both issues.

Cheers Daz, will see if VCDS lite picks anything up once I get the cable.

I'm doing the bypass today, my vagcom gave me "17705 - Pressure Drop between Turbo and Throttle Valve" everything seems good under there.

Let us know how you get on,many do the bypass of the N249 valve.

Its not the bypass I need to do; 2 hoses perished, pretty much pulled apart, breather hoses, common fault.

06A 103 213 AF - Breather Hose
06A 103 221 AH - Oil Breather Hose

£87.77 for the two hoses from my local TPS shop!! Could get silicone ones for less than that but need them today :-/

Replaced the hoses this eve, what a pig the lower one was... Now i have no gauges (speedo, Rev, Water, Fuel) no odometer and no dash illumination!!! I have had it with audi's!

That doesn't sound good! Any idea what's caused them to go off?

PowR_Remap

Only thing I can think of is me pulling all the fuses out one by one checking they were all ok as left sidelight one had blown. I thought I should check them all... :-/

How strange, can you disconnect the battery and leave it for a while, as for Audis I didn't expect the running costs etc to be as high as what they are.

PowR_Remap

Did that, also double checked fuses etc everything... its a money pit

Need to wait until later and see what codes have come up now..

Sjdickso

Like you say just seems to be one cost after another. Hope you get it sorted.

PowR_Remap

Dash seems to flicker now, going to remove the cluster tomorrow and check for loose connections!

PowR_Remap

Had the dash pot out today, checked the connectors, checked the back of the fuse board :-( nothing.
