Right, back to the original problem.

The timing on the PD BKD system needs to be set extremely precisely since the fuel pump, injectors and the cams/crank need to all be timed correctly to work together otherwise it will feel like its down on power, most garages would get the cams and crank sorted but some may not have the technical knowhow on getting the PD injectors and fuel pump in sync with the cams and crank.

We had similar issues with a Mondeo Diesel many yeras ago, transpired when another garage finally got hold of it the replacement belt was a couple of teeth out. Im assuming this has been checked

Timing is an obvious thing to check. Has it been to a VAG specialist/dealer?

I'd also want a compression test.

Maybe on a Renault, but I still say this is highly unlikely on a 2.0 BKD engine.

Just rereading the thread and realised the OP has a 4x4. So it'll have the 8v 2.0 (BMM?)

But the advice still stands.

Well, months went by, extended by illness, unemployment and borrowing Mum's old fiesta.  Then...

... today I got my Octavia back from local independent diesel engine specialist, where I took it in the summer on a recommendation from a friend: after a long, long time going through everything they could think of, they eventually decided everything had to be OK... except the injectors.  Which, of course, are stupidly expensive both to diagnose and replace: eventually I took a punt on some secondhand ones off ebay, they fitted them (I was charged for two hours labour, no idea how long they actually spent) and hey presto it's working.

 

So, that's a new head, turbo, and injectors - total cost about £4500 - and I now have a car that I can hopefully sell for £5000.  Mmmm.

Ouch. 

 

Glad it's all working now. 

I couldn't bring myself to sell the car after spending 4500 on it. Would it not be worth running it for a while to get value out of your hard earned money?

Good news in the end. Glad all is ok

Funny I also had the same belt issue on my megane, twice.

when I got my cambelt done last year at a skoda garage, they recommended that I put a new aux belt on at the same time, so I guess they know what could happen if the aux belt fails

It's a no brainer if you are changing the cambelt.....the aux belt has to come off anyway, might as well replace it for a new one for all it costs. 

Hi I had a similar problem with a Freelander 2 losing the oil pump and breaking the engine big style. Spent £3k on that repair and sold straight away, lost approx £8k in a years driving.

Peace of mind or confidence after a major engine failure and rebuild was not there even with the garage promising it was 100% correct etc, so even with the massive loss it just had to go.

Only you can call that one on whether to sell and cut your loses.
