Hi All,
(Audi a4 1.9 Tdi Avant 130 BHP AVF manual 2003)
Since i brought my car the turbo appears to be kicking in very late having driven other 130 BHP TDi's in the VAG range it appears sluggish.
I would expect the turbo to start to kick in at 1400-1600 revs but only starts to around 2,200 revs
A local mechanic diagnosed a MAF sensor - this was replaced and i felt the turbo to be more responsive but again only after 2,200 - 2,400 revs
it is especially sluggish in 1st 2nd gear and in the 6th gear - it tends to just stick at 2000 revs for a while in the 6th and take a long time getting speed / revs - but the revs do go up in the high end 4000 plus - so not restricted
going uphill again it just sticks to one speed with little to no acceleration / revs
the cars done 155k - but i driven an A6 with the same engine on an auto transmission with 480k on the clock ! and it pulls so much better then mine
ive done the below
1, MAF replaced not fixed.
2, removed MAP sensor - car was completely sluggish with no turbo at all
3, replaced MAP with another one - no cure
4, OBD diagonstics showed desired boost pressure and actual boost pressure to be very similar and the mechanic suggested that my engine shakes in certain revs and it could be injectors -
has anyone had similar symptoms should i be now looking to replace the N75 value - ( boost pressure solenoid / controller )
thanks !
