Down on power....

[182_blue]

Robin, sorry to hear it doesn't seem to be a simple fix

Draw out the positive and bung in the K04

....Hurdy!! WTF are YOU doing here! Feck Off! and stop being a bad influence!
 

Remember....Jesus says...MODIFY IT!

He's probably off on a DD rolling road....

No, you're wrong on this occasion - The negatives outweigh the positives - For me personally, you understand, and not for others.

Only trying a little baiting

Oh TC you need that smilie above

Leave the poor guy alone he comes on trying to find his turbo faults and every one beats him round the head with a KO4 mallet
Red do what suits you your the one with your arse on the seat.

I was expecting the K04 mallet. I actually said to a friend (forgotten who!) that lots of people would be suggesting the K04 when I started this thread. I understand the reasoning and the quest for bhp, but....

Like you said though, if you want low down driveablity, then the K03 is the much better option.

Perfectly described, TT - "low down driveability" is highly desirable in the UK with all the feckin speed limits. Besides, even on the occasional forays into Europe, a well modded K03 GTI is quite respectable. In fact, a totally standard K03 GTI is respectable!

A good friend of mine drove his very highly modded 290 bhp Mk5 GTI (K04 and Quaife etc etc) to the Spanish GP and then found some nice mountain twisties etc. But he ate a set of front tyres in just a few weeks!!

I know that feeling!

Only done 12k and soon coming up to the second wheel pair on the front. I don't consider myself to be particularly over exhuberant with the right foot all the time either

I have now been running around for the last 10 days in a Standard GTI, covering over 750miles (hey its not mine ;) ) and I have to say the standard power is still nothing to be fobbed off - its so smooth and still quite nippy when you drive it well, I have to say its a shock when first going down to it but you get used to it and its plenty quick enough.

Manual is also fun for a while but missing the DSG and milltek now

I had a chat about my problem with my VW dealer today - Specifically the guy who is now on the Service desk but who still occasionally doubles as Mechanic and is now a Revo agent. In other words he's someone whose opinions I trust and someone who can 'take off his VW hat' and be unbiassed with me.

On the basis of everything I was able to tell him, he reckons it's probably the wastegate at fault, which of course is an integral part of the turbo.

After asking why I didn't consider a K04 but understanding my reasoning, he also said that a K03 turbo wouldn't be run in until about 8,000 miles [cue for TT to spit and splutter his disagreement] so the option I was taking was a good one, also taking into account hire car costs.

I'll keep this thread informed, neg, but I am out Friday night and with the Biali boys at APS all Saturday (I'm hoping!), so it may be well after the turbo investigation on Friday.

turbo's don't really have a running in milage

they aren't really a component that requires running in. Once a new turbo is fitted, primed with oil and then ran it'll perform the same from day one untill either the oil seals fail or the bearings fail.
The main variable that 'wears' on a turbo is the actuator.
The diaphrams can split or more commonly the springs wear - easy fix, buy a new actuator.

Not read through the many pages of your topic, but the actuator might be worth checking.

Thanks, Tom.

I think that the actuator is integrated in the K03/K04 turbo, or at least can't be inspected separately. I stand to be corrected.

^ Every cloud has a silver lining! ^

So, you see, my turbo problem has its benefits

All actuators are revovable, it's the penny valve on the wastegate itself thats a turbo off inspection.

They might mean that theyhave to loosen off the turbo to get the actuator out due to it's location on the turbo. (note i've not seen it's placement on the turbo)

And your silver lining is a cute one  lol (even if it is a picture)
