Hi there,

I have a 2008 Caddy 1.9 BLS converted to ASZ.

Recently the engine has started to knock, the noise is coming from the EGR/turbo intake pipes.

It's also really down on power with a lot of black smoke when you put the foot down.

Also been going into limp mode the past few months, but a lot more so since the knock started.

I have done a compression test and all is good.

Would love some help as it's wrecking my head.

Thanks Wilson

First posts normally go in introductions else you could get a free fix and we never see you again!!!

Your car spec says 0, only what I've added from this thread.

How long is a piece of string?

We don't know what has been done or tried.

You need to get your motor scanned (preferably with VAG-COM\VCDS) for any error codes logged in the ecu and post them, that will save a lot of guessing and check systems out.

Knocking from where the cylinder head or somewhere else?

Manufacturer: VW, Date(s) Used: 06/2005-08/2010, Model: Caddy, Engine Code: BLS, 77Kw, 105PS, 1.9 Ltr, 4 Cyls, Remarks: Turbocharged Direct Injection Pumpe Düse (TDI-PD), 8v Timing belt

The ASZ engine code isn't fitted to the Caddy are you after more power?

Manufacturer: VW, Date(s) Used: 05/2001-04/2002, Model: Golf/Variant/4Motion, Engine Code: ASZ, 96Kw, 131PS, 1.9 Ltr, 4 Cyls, Remarks: Turbocharged Direct Injection Pumpe Düse (TDI-PD) Timing belt

Done a scan today and there is no codes coming up.

Knock is coming from the EGR and turbo intake pipes.

The van was converted from BLS to ASZ block.

Wasn't sure where to put this post.

Done a scan with what a generic scanner?

That is a common sign of camshaft and hydraulic lifter failure... a VERY common 8v PDTDI problem.
