2007 VW T5 2.5TDI Limp Mode

[Griphon]

Good day All,

I hope you are all well. I would first lime to start off by saying I really enjoy my VW Bus...but she is being difficult.

Let me give you all a bit of history. Well, when I purchased the van I had the turbo replaced and boost pipe seals. A couple of months passed and I blew a boost pipe, which I replaced.
The bus ran fine for a while and then she was going into limp mode randomly. When standing infront of the vehicle I felt some air brushing on my legs. I looked down and noticed the intercooler veins were bent. I have since had the intercooler fixed.

Now I am sitting with a situation, when I start the bus, the revs would pick up to 1200rpm and I dont have any throttle, when I engage 1st gear and move slightly forward, the revs normalise. I then rev the engine to 2500rpm and she goes back into limp mode.

I dont know what further to check, apologies for the long winded story, I just thought I should share. Any ideas

Regards,
Griphon

U gonna have to scan the van with a diagnostic tool to see what fault codes it's giving u.

That's not a common issue.

Most commonly on these are the exhaust manifolds. They crack = limp mode. But that wouldn't cause the accelerator pedal not to work.

On other Tdis, when the rpms raise on its own, its an alternator/wiring issue - again that doesn't affect the accelerator function.

U could just have a fault pedal. Only way to tell is to scan it.
