Not Making The Figures...But

[master_oogwai]

This said you may think that if no gains are made then youve wasted money.

This is what I am thinking.

But, from what you are saying, unless I try a new Maf, I will never know for sure. Guess I will try a new maf and pay R-tech another visit and take it from there. Thanks Hulmie.

I got a new maf earlier and swapped it over. Turn the ignition on and it was idling fine, no dashboard lights, nowt. Ran the car through vagcom and a fault saying air mass flow signal low - intermittent. Cleared the codes down and ran vagcom three more times and no fault code came back.

Can I assume the fault appeared the first time was the ecu still trying to adapt to the new maf??

Took the car for a brief drive around the block and pickup seems better (maybe its late and it got colder, not sure lol) and maybe its just me, but the recirc valve seem to have got louder too.

Anyway, will take the car out again later tonight on some bigger roads to see if there are any differences

The code will be there because you unplugged the MAF

Ah right, cool.

Thanks mate. This is all new to me and still learning 

It was the guide you put up for changing the maf I followed so thanks for that. If that was not there, I would have asked the dealers to replace it.

No probs

Keep us updated

Sorry to bring up this old thread. I thought it would be better just to continue where I left off.

Anyway, I knew the fun would not last 

Its probably me who is causing this issue, but I thought I would put this through the more brainy people on here and see if anyone can advise me?

I swapped out the maf on the 5th March and ran the car for two days to make sure everything was ok before I gave my original maf back to VW as an exchange unit. The car seemed fine, no power gains or losses that I can notice. However, the beginning of this week, I had noticed the car seemed to be, how can I put it? seemed to be 'bunged up'. Like when you have a cold, you have a blocked up nose and you have trouble breathing through it. This is how the car feels. Gears 1 and 2 you dont really notice it, but from 3-5 and you give it half,full throttle, the car slowly picks up speed, followed by a little turbo kick and picks up speed again. Before, you give it half or more throttle, the engine feels loose and it flies. 

Stuck my head under the hood with a torch and cannot see any loose or split pipes. I am not 100% sure which pipes I should be checking, so I looked at all the ones around the airbox, tip and anyone other one connected to the turbo.

I checked the maf and the tip to make sure they are fitted correctly and the maf is snugly fitted inside of the tip. I did have an issue of putting the airbox back together and it popped open the other day, but I have sorted this out. The airbox is tightly shut now.

Ran the car through vagcom a couple of times, but no faults at all.

The other thing I have not changed yet is the n75 valve as advised by r-tech. Reason being someone said if the car is boosting at 23 psi, the n75 valve should be ok.

Surely, the maf would not have buggered on me already can it?

Would changing the n75 resolve this issue?

Any help would be great. I only want a working car

have you adjusted the actuator? im in the same situation just fitted a brand new K03s and i feels really slow going VW tomorrow have another MAF fitted see if that the problem and going R-tech on sat to see if my actuator needs adjusting!

I am not sure if Nick had done this when he fitted the ko3s. Chris also did mention this in his post in this thread, so I think I my have to give them a bell to arrange another visit.

If you can let me know of your outcome, it would be much appreciated mate. I dont really fancy buying another maf from VW, as they dont come cheap and does not resolve the issue.

my faulty N75 gave me too much boost so it is possible mate

Cheers mate.

I wonder if this is a part i can pick up from GSF?
