Please help!!
Recently we've had an intermittent fault......It's a 2.5TDI Tip, when accelerating the engine will produce less and less power, eventually stopping any acceleration above 3000rpm. If you put your foot down any harder it actually slows down!
You end up not being able to go any faster than 30mph!!
The garage has changed the airflow sensor, (twice to make sure!!), checked numerous other things, solenoid actuator for turbo waste gate but we've still got the problem!
Any ideas!?
:w00t:

Hello, I saw your problem which is similar to another post from Matt - I've copied the suggested remidy here for you. Good Luck!

Mark :)


just wanted to post and give you some advise re these problems,

i had the very same problem, but mine seamed to get worse and worse, until the car stared to smoke on tickover,

there turned out to be 3 problems that can cause this type of fault,

1 the number 3 injector has a sensor to read the neadle position, this was showing a fault on my car, this was changed and made things better but not as good as it should be,

2 now this could have been the killer, took the car to the local audi dealer, and after they had finised looking down there nose at me they agreed to have a look at the car, 3 days later i got a call to say that they had forund the problem, and that the turbo was on its last legs, £1200 plus fitting and oil change,

after getting up off the floor, i agreed to collect the car as i could not afford to have the work done, after chating with one of my mates we decided to have a look at the car our selfs. after looking at the car for about 20 mins we found that there was a blocked breather, its located in the top of the block under the fule pump pipes, its like a filter, ordered a new one from audi at a cost of £35, and now its a different car more power faster take off and more mpg,
Audi have said that this is not a service part and there for would not be checked of changed on a normal service,

3 there is a small pipe running up to the turbo that can get blocked and this causes a loss of power at about 3000 rpm

well hope this helps some one out there,

thanks

Matt

Can someone please tell me what the crankcase breather filter looks like?

Also does a big pipe go from it into the intake manifold. Sorry for being stupid but my car has problems which make this the problem.

A picture or diagram would be fantastic. Thanks

Hi,
pls.try to verify if that is the part number you're looking for,it goes as head block vetilation filter check parts-046198475A or 059198067.
you can try at vagcat.com but you have to register first.
I myself had a shop change it for ,all I recall is that they had to wait for the turbocharger too cool first to gain access to it.
Good luck.
