Hi performance wasn’t that great apparently it had been mapped previously, I got it mapped because of no low down power,setting off from junctions, I’m not too sure what to check next, thanks
Hi guys I’ve got a 2005 a4 1.8t 163 just had it mapped but having boosting issues ie the car isn’t requesting enough nor is it providing enough,bit like driving a none turbo car. It’s had new air flow sensor,n75,recirculating valve and injectors.
I have a b5 1.8t Quattro avant on a k04 and it’s...
No unfortunately I might just bite the bullet and buy one
I've read quite a lot of posts that say at 3000 rpm the air flow meter should read 10gs mine reads around 14gs which leads me to think the air flow meter is reading incorrect
I haven't check it it since fitting the turbo but I no it had a leak because it was over boosting
To 30+ psi then the fuel cut off kicked in
(It went like stink then)
It didn't boost flutter when it was over boosting
Yeh I don't think it's doing 230hp the boost seems weak that's why I thought it could be the air flow meter,Ive changed the DV no change could it be the n75 or a fuelling problem
I will do another boost leak test this weekend.
Can anyone help me with these readings
1999 Audi a4 1.8t quattro sport AEB repacement engine original one was AJL
running k04-015 turbo de-cat exhaust 2.5"
im getting boost flutter below 3000 rpm wot and a lupy tick over no boost leaks
i have taken some readings via vag com and i dont...
i have had another look and there is definitely 2mm or more in and out, when i looked close with a torch there looked to be small marks on the end of the turbines.
I took the charge pipe off the inlet manifold i would have said it was excessively wet.
there was a lot of oil in the inlet pipe as well were the recirculating vale releases pressure.
Had a look at the turbo and there is a good 2mm of side to side movement and alot up and down.
time for a new turbo i think any suggestions it is on the standard ko3-026 turbo.
coolant look fine when when cam belt was done don`t no about head gasket but there are no head gasket symptoms,
oil consumption i am testing at the moment going to check the shaft for play today looks like fun.
