Worst case scenario of blocked DPF on transporter?

[DeLorean75]

Could someone tell me what is the worst case scenario (financially) of a blocked DPF on a T5 transporter that still starts and runs in limp mode?

Is there a limit to how damaged the engine could be if the vehicle still runs albeit in Limp?

Maybe an impossible question.

Thanks

I don't see any reason to expect the engine to be damaged at all.

^^^^ Wot 'e said.

No reason it would damage the engine unless there is an underlying reason for the DPF issue that has also affected the engine.

But if the dpf is blocked then how do exhaust gasses escape? I’d be concerned.

Blocked doesn't actually mean blocked, it means there is too much soot in the DPF for it to flow fully hence why it still runs but only at low power.

If the DPF was actually blocked the engine couldn't run, or would have blown a hole in the exhaust pre-DPF.

Question pertained to non runner in classifieds...I'm too chicken!!

[GTVOX]

If someone is selling a T5 as a non runner and claim it's just the DPF then they are not telling the whole truth. Check the T4 forum theres lots of advice on T5's too.

Maybe if it’s trying to regenerate all the time the oil may become over full with diesel and lead to problems.
Just a guess, I wouldn’t continue to drive it personally.
Brother in law lunched his engine when he continued to ignore the warnings.

Trade seller...had to figure they would fix if it was that easy

Not same car but probably similar engine - I had a 2010 TT TDI which had blocked DPF and was permanent limp mode. VCDS or VAG-DPF will show the detected soot content. I managed to clear mine using Mannol DPF cleaner sprayed directly into the top of the DPF. That got the soot amount low enough for a proper regen to happen. Car still running well 20k miles on.

If you try it, do it in the middle of nowhere as you might create a bit of smoke!

The problem might be easily fixed and you'll be stuck driving a T5?

Ok you win !

No ?
So what cokes up the internals ?
The EGR & DPF system on these vans are well published for carbon build up on various levels.

We had to replace our EGR on our 61plate T5, think it was over £800 with a mate doing it. Cleaning wasn't possible/sufficient.
