Right then, after months of engine warning light going on and off whenever it felt like it (with no other symptons), the light went off the other day so I assumed that it had 'fixed' itself again. 2 days ago, the light came back on and this time, I lost power.
Now when accelerating, there is a very noticable drop in performance and it sounds like the diverter valve is continuously dumping the boost (exactly like when you lift off the accelerator pedal). Checked the engine with VCDS yesterday and I got the following faults logged:

It looks like I have a boost leak! Any ideas where to start looking? I did have problems with the standard dv on my old S3 (1.8T), but I don't know where it is on the 2.0T so I'm not sure what to lok at first.
Any suggestions would be appreciated.
Oh, and to anyone that says they told me not to ignore the engine warning light: yeah, yeah, you were right! But I DID try to get VW to look at it!!
Thanks

Have you get an OEM diaphram DV? I'd start there.

Yes, and that was my thought as well. My question is, where is it on these engines? I haven't really looked yet, but I thought I'd get some ideas before I went out to look. It was too dark last night to start looking for problems.
Thanks

Its on the back of the turbo on the K03's. I'm pretty sure you can only get at it as well from under the car.

That's what I feared. Thanks

If you've got one, I'd change it for the D-type piston version even if it isn't broken (which it most likely is) as it'll just go anyway.
£40-ish from the dealers I think?
-
No worries, I've got the same job to do this weekend anyway so gives me something to look forward to :signLOL:
-
As above, accessible from underneath and stick with the OEM one IMHO.
-
Thanks guys.
Anyone have the part number for the updated version? My ETKA is old and only has mk5's upto 05 (like mine).
:drinking:
-
06H 145 710 D
Retail price £50.52 I think. Ask for a discount.
-
Thanks Dan. Oh, and I always do :happy2:

What are your reasons for suggesting the OEM one? Apart from the price, why not the Forge one?

If you're not in a rush I may end up with a spare DV valve up for grabs in the next week or so...

I had the same thing a couple of weeks ago, dealer charged me £46 for the rev D piston type DV. The most awkward part was getting the car jacked up high enough and on axle stands so that I had enough room to change it, wasn't hard once I got going with it. The tear in my old DV was about 2cm long and my car felt miles better than it had for ages once I got the new one on!

The piston is electronic so no vacuum and it has been proven to work very well. The main thing is the price though.
K04s might benefit more from the Forge one though???

Pretty much as Tony says, the OEM solution is adequate now so there isn't any need to pay more for a lesser solution. The Forge one isn't infallible

Thanks guys, I'll order one now.
mojo, thanks for the offer, but I need to sort it out quickly. I can't really drive my car in it's current state.

sorry to jump on the thread.
I have an original dv and have been meaning to replace before it fails, so if you do replace please let me know.

Drop me a PM, say next Friday and I can confirm if I got the DV.

^^^ will try to remember.
No panic for when u sort it. Baring Sod's Law been in and ok for 5 years.
Only one error on vcds.
Thanks all the same :happy2:
-
I've got my new valve now (sent the lady out to get it earlier) so I'll be fitting this tomorrow. I'll take photos if anyone is interested in them?
-
Yes please...
Planning on using those wheel on ramp things. Hopefully there will be enough room to work under.

Well, i replaced the diverter valve with a new revision OEM one and by god was it a hard job.
It should be simple but as there's no access to the valve from above, below or the side without contorting your body into totally unnatural positions. It took about 3 hours in total, that was about an hour per screw. They were tight from start to finish :sad1:
Anyway, old verses new valves:
New on the left, old on the right.

And the damage to the old one that was causing the boost leak:

All sorted now and the car runs fine. The engine check light is also out now too :smiley:

Well done...great to hear a happy ending!
