2.4 TD 140 loss of power and then good again.

[myrebuilder]

Hi all.
I just sold my old 1998 transit luton buletproof workhorse and bought a 2007 2.4TD 140 luton van. I was driving 100 miles today and at some point the yellow light with the gear and ! inside the gear (in the tach) came on and I felt that the accelerator was not responding as before. I went by the side of the road and shut the engine off. After 5 min I started the van and the light was off and the power was fine for the majority of the trip. When I reached the town and stopped at a stop light, the van would bearly pull itself even when I was flooring the accelerator. As I was changing gears it wiuld behave a little better until I stopped for a bit. Then again when I started it up it was fine with all its original power. Is that a PRV fault or something else?

If the powertrain light came on, you'll have fault codes stored....you'll need to get the codes read before throwing parts and money at it.

I'm guessing EGR or possibly PRV & SCV...but getting the codes will help diagnose the problem.

Hello from New Zealand. My '02 LWB van problem is somewhat similar: Temperature gauge reads well less than half with normal running but pulling heavy loads uphill increases the temperature (naturally) rather rapidly and brings an associated significant loss of power, to the point where a change down is necessary. It struggles even then but next the temperature gauge falls rapidly and that brings power return to normal - until it eventually bogs down again in that gear and the same exercise is repeated. Can anyone say with all confidence WHAT component is creating this problem?

Very disappointed to have no response from the forum on this issue. C'mon guys, get with it, please.
PS There is no warning light coming on when the problem occurs.

This particular thread is for a Mk7 140 TDCi.....you have a Mk6 and probably a TDDi, which is a different animal with a different engine, different fuel system etc... with a totally different issue.

I think it's best if you start a new thread with your problem.

Sorry for the late answer.
I just changed the fuel filter and everything was magically sorted!
Thanks for all you help and comments.
Now I have another strange problem. Please see my new post.
