I know the topic of stuttering on the 1.8t has been well covered... but I've done a search and I can't find any conclusive answers to this, so please don't flame me!

I went to overtake a slow moving vehicle a couple of days ago... we were traveling at approximately 30mph. I dropped into second gear and put my foot down to get round quickly... 30mph in second would usually pull like a train, but for a moment nothing much happened. If felt bogged down, as though I was asking it to pull from very low revs.. then suddenly the turbo kicked in and off it went as usual.

Today I had a similar experience again, and I also noticed that when pulling away using moderate power (reasonably fast moving town traffic), it was quite jerky at times.

My gut feeling is that the N75 has finally let go. Last year I had similar symptoms although they were less pronounced. It seems to be worst when it's very cold outside but the engine is warm... I don't know how true that it, though.

VAG-COM didn't show any faults. The MAF was changed last year for another reason, so hopefully that can be ruled out for now. The plugs have been in since July and have covered around 6,000 miles. Throttle body was cleaned and alligned about 6 weeks ago and the engine generally runs perfectly bar this problem (and the usual cold start stutter which I'm not too worried about).

So I guess my question is to those who have changed their N75 - do the symptoms sound right, before I throw money away!

Cheers

Phil.

Phil have you cleaned the throttle body recently as the majority of boost problems seem to be happening in higher gears?

Yours is in 2nd which is why iam thinking dirty throttle body

Yes Mate, about 6 weeks ago IIRC... I suppose another allignment wouldn't do any harm?

I thought N75 would show up on Vag-Com?

How much do they charge to do an allignment anyway?

So it only does it in low gears...very strange

You can do it for free with VAG-COM

seems to just be second... although I don't know if its significant :confused:

FREE is good

(Have you done the T.I.P?)

Funny, mine had a little blip this morning. Nothing major but it was very cold, I was on the motorway sat at 80 and a little miss. First one I've ever noticed

Maybe a cold thing perhaps

seems to just be second... although I don't know if its significant :confused:

Sorry to bring this thread back up, but did you sort this out? mine is the same only in 2nd gear.

have you checked the air filter recently or performed a throttle realignment??

Air filter is a pipercross one which i cleaned recently, not done realignment, not got vag-com.

To be fair the ECU should adjust over a certain amount of miles anyway...

Mine is the same in 2nd gear too. We are going to clean the throttle body this weekend, but what is the alignment you talk about? I have vag com so no problem there just not sure what you do :(

Go to engine 01, 08 measuring blocks... then look at group 060.

Switch to basic mode and leave it for 30 seconds (should see adp run and the values change a small amount).

Switch modes and that's it!

Make sure you don't touch the throttle whilst doing it.

Mine has been doing this at low speeds lately so I may have to try this cleaning mod. Down side is I'll need to find someone in hull with vagcom who would be able to realign it.

If you get stuck give me a pm.

And don't have your engine running
