TDi 110 Help Down on power!!

That would be a dead MAF.

That would definitely suggest it. Only way is to log it though.

yep agreed, the unplug 90% confirms it. a log would 100% confirm it, but unless you have access to vag com on a laptop you wont be able to.

best get it exchanged at a dealers, should be about £45 i think.

MAF for sure, that's exeactly what happend to our 110 Alhambra and when we stuck it on a rolling road, it was on putting out 80 odd bhp

yep maf! the unplug is a sure way of telling, new maf and it'll be like a new car again, had one go in a golf i had then replaced it and made such a difference.

Cool, nice one dlloyduk. Glad its all sorted.

The merc maf should work well with your engine, ive heard of some probs with modified and PD engines but your standard 110 should be fine with it.

I used a merc maf for a while and my car is chipped. Had no problems at all.

its mainly tuned PDs. I read about it over on uk-mkivs.net

Can someone tell me wot a MAF does/is please? Im sorry for being thick in advance

Baz

reads the amount of air going into the motor adjusting fueling and pressure based on these values.

Paulo, there's a guy in here [don't wanna say his name because he may want to expose his experiment by himself] who played with a maf and a evry mod together and he says the smoke is almost zero,,, I thought that tricking the maf would lead only to even more fuel and so more smoke. Could you confirm this?

It doesn't sound right, but I have to check and think about it for a while.
Generally, if it's reading more air than it's going to inject more fuel.

Prc...but does'nt the fuel map/map sensor have the last say having a requested map/load then receiving above this will send it into limp ,where as tricking the map sensor means the the ecu thinks its got the requested boost pressure but really it has'nt .
Like for instance putting bigger nozzles on will trick the system/ecu because theres no way it can detect them like the ivry mod , but like i and others have said before unless more boost can be implamented its going to be very smokey and could be said that the working state of the car is like being in open loop and at some point the timing will not be where it should be.

Yep
there are a few maps that have a sort of higher priority, so even if you request 6.0bar boost pressure in boost tables it gets cut by other maps (or the max boost pressure point in code. ).
I have to check some of maps I have to check...not an expert you know.

Like someone else has stated b4 if actual is way under requested this can send it into limp mode too , if you look at most of the maps as lines of writing on the top line is where the top performance is e.g w.o.t ,throttle position, load, timing, ex,ex , and on the second line a lesser performance map and so on , this is why when/if big if you let the wife drive the car at her stonking pase not and we clime back in there's not urgancy at before.
