Now, I just installed a new K03 turbo after I blew up my factory K03. Ever since, If i give it mild acceleration, it runs smooth and picks power nicely. If I give it moderate gas, it gests a nice boost followed by immediate kickback and if I keep the gas pedal pressed after that for more acceleration, it does more kickback and goes in a sort of gear changing frenzy with moderate acceleration but not with type of boost that it begins the whole thing with!!!!

I tried putting the car in individual gears and give it gas, but still did the same thing!!

Before I blew up my old turbo, I would get that kind of a kick..maybe once in 1-2 months and I never gave a second thought to that. Once I blew up my turbo, I drove around for about 50-70 miles but it still did not do this. So, I am kind of surprised and scared..
Any thoughts/ideas??--_Tx

I want to feel that complete boost......*&^*(&^%^&#&$# it just sucks again now after getting a whiff of it

 

Bump...
So many views..No ideas to begin with?

 

If it starts gear hunting then your maf might be bad, damaged or on backwards.

 

So, I did a test run after taking the connector to MAF but still was doing the same...
Finally, got hold of VAG tool and it showed 3 fault codes:

1. 17956-Boost pressure regulation valve(N75)-Open Circuit P1548 (Boost Pressure Contr.Valve Open)
2. 16486 - P0102 (Mass or Volume Air Flow Circ Low Input)
3. 17963 - P1555 (Charge Pressure Upper Limit exceeded)

In apprentices above, I have written what I have found for the codes at Bentley publishers website.
For N75, I searched and realised that majority have to change N75! Has someone gotten away with just cleaning it?

For MAF low input, what should I do? Clean it or change it? I was thinking I should do a cleaning first and then see how it goes.

For Charge pressure, I have no idea..maybe becoz of the other 2 codes???


Tx again

 

Check your Boost lines. Mine did the same thing when I went k04, and after looking harder I found numerous boost leaks. The biggest to look for is where the vac line connects to the turbo and the elbow that comes out of the back of the intake manifold to brake booster.
