Re: Whitestar 1.9TDi 1z won’t start.

My money would be on a bad (crusty) connection inside the round engine wiring connector-Good place to start.

Re: AFN TDI Throttle problem

As stated it sounds like a wiring problem but what type of throttle pot do you have? is it the barrel type or have you gone for the 'all in the pedal' variety? If the latter i would be looking closely at the extended wiring (assuming ecu in the rear). Have you tried Dr Tim for any help?(ultimate eng...

Re: 1.9 AFN TDI silly question

i put in a 1998 Audi A4 engine in with the larger alternator which meant modifying the hatch so no nasty 'lump'on the westy rear bed. only real issue i had was cutting engine bar offside but whatever you do it always takes a bit of head scratching :shock: . Tim will no doubt be able to answer any en...

Re: 1.9 AFN TDI silly question

A Un1 gearbox is also longer than VW gearbox and will require 'modification'of the cross member-basically chopping the centre section out and constructing another crossmember to hang the gearbox front mount from so even more work for those who choose that route. Not something i wished to consider! A...

Re: MK1 Audi A3 1.9 TDi not starting (AHU 39****)

Does the AHU have the round screwed connection to the fuel pump wiring harness? I think I would be looking there if it does for a "pooh" connection-green verdigris on the connection pins etc. Think the OBD socket is an easy fit if you have the correct pin out diagram(I don't) for that year...

Re: T25 1.9tdi engine judders/hold back

Sounds like a early 1z engine. If it won’t rev at all or above 1500 rpm it could be because the ecu cannot see the throttle potentiometer. Typical fault could be the round multipin connector which is not in full contact with non fuel pump wiring or has verdigris affecting it. You could do with vagco...

Re: ENGINE POWER

Hi As Clairvoyancy is not my strong point can you supply a bit more information? A start would be an engine code-is it indirect or direct injection (AAZ or 1Z AHU,AFN etc ) turbo type etc. what other symptoms do you have? who did the installation /conversion? A picture of the engine bay may help mat...

Re: 1.9tdi 1z exhaust

Im pretty sure Tim at Ultimate engineering can supply adaptor plates for whatever turbo you are using to the standard exhaust as long as you are using the standard jx manifold.
If you are not it is bespoke Im afraid as Andy has pointed out.

Re: New T25, has a TDI Passat engine

That is definately not a pd engine. looks like a 90/110hp tdi variant as fitted to passats judging by the angle of the oil filter with a AAZ INJECTION pump connected. Dont know what the performance is like-do you have a turbo fitted? i didnt think that type of pump would operate the injectors correc...
