Boost leak/DV faulty ?

[Aleksii]

Hey guys,

So I was on my way home last night, and after normal driving (no thrashing), I put my foot down, felt the car pull and as it hit boost, it just hissed a lot louder and the car felt like it hit a flat spot and just wouldn't pull like it usually would.

I have the APR upgrade and Carbon intake.

I spoke with Prestige Performance and they say that it sounds like the DV is 'kaput'.

I've got my car booked in for next week, so I guess I won't know for sure until then.

Do you guys think that this sounds like a faulty DV? Or a leak in one of the hoses?

Thanks guys

Have you opened the hood for a look??

[Aleksii]

look

Unfortunately I haven't had the chance to have a proper look yet.

Where exactly should I be looking? Where is the DV located?

[Aleksii]

I'll have a look this afternoon when I get home from work.

DV is under the top right corner of the engine cover.

Correct me if I'm wrong someone?

Unfortunately the DV can only be seen from underneath the car... so your going to have to jack it up.

really! ours (Polo's) is just under the top right corner of the engine cover, as Aleksii said. Upgrading the DV is only a 10min job! (well that's how long it took me, and i've never fitted one before)

I wish it was a 10min job! I would have probably have done it by now LOL!

OUCH! Thanks Alfy!

I guess that will give me something to do tomorrow morning..

Thanks for the feedback guys, I'll let you all know how I go.

The car is booked in at VW for next Friday.

I guess all I can do for now is have a look at the outside of the DV and check the hoses.

Ok, so I 'attempted' to get under the car, but not having ramps, that was impossible.

I switched the ECU over to the stock setting, and the car feels like a snail.

I'm pretty sure that it's the DV that's poo'd itself.

Is this a common thing?
