2.0 this tiptronic acceleration problem

Recommended Posts

Hi, wonder if anybody could help.

Have an 2004 audi a3 2.0 tdi tiptronic. 

Have some problems..  on start up it needs cranking over a bit, (could deal with this) however when driving it the other day left the house fine pulled over at the shop went in come out started car up put in drive and went to pull off and no revs or acceleration.. Turned the car off and on again still nothing...  Then off we go (about a minute) get going along again stop at the roundabout same thing again..  However when this happens I lose all revs it drops to about 800rpm.  When it eventually goes back to 1000rpm it seems to go OK. Seem to have like an engine cough occasionally Aswell. Have plugged in vcds and nothing obvious comes up... Any ideas before I start throwing money into it.???  Tia

It could be dozens of things causing the fault Tally. Rather than wildly guess at it and send you on many wild goose chases, you would be better advised to have the problem analysed by someone with the right equipment. It would be cheaper in the end.

Hi Tally

I agree with cliffcoggin the list is endless as to where to start....however, the first place I would start is with the throttle sensor but to check this you would need live data running on the VCDS. This should show a linear reading from closed throttle to fully open with no glitches. If the reading does not change then there's your problem.

After that I would try measuring fuel pressure and see if there is a problem there.

Good luck and let us know what you find

Cheers   Trevor

Hi sorry to be a pain do you happen to know what measuring block we should be looking at for fuel pressure?

and I have also checked the Throttle position sensor and it seems to be fine from 0-100%, have also changed brake light switch from behind the peddle just in case and no change

 

Thank you

sorry, not sure about the measuring block...I normally use a Snap-On scanner and look at live data for what's occurring when the fault happens to see what is going on.

OMG =O Had my turbo veins changed as this was also an issue. Also had EGR valve deleted (which is one of the codes) But an y idea what the others could be ... really starting to lose hope with this car now and kinda wishing i didnt go for an audi and stuck with my manual golf =(

Until I read that you had the turbo vanes replaced and the EGR deleted, these were going to be my conclusion.

Were all the codes been erased after fitting turbo cartridge and the EGR delete?  If not, these are prior to the faults you are experiencing.

The only other thing I can note from the list is that the Battery voltage went low...if this is not a one-off then maybe it could be related to the running fault?
