What is the best way to test for a blocked exhaust on a diesel? Disconnect the exhaust after the turbo, or do a temperature test (before after the cat or muffler), or other?

what makes you think it is blocked?

1. I was looking for an easy way to check this on a diesel, as you can't hook up a vacuum guage, like on a petrol.Originally Posted by schuy1
2. Also, looking for reasons why the turbo doesn't spool up on another forum member's car.
The obvious has been checked. At 2500 to 3000 up a hill and pedal all the way down, the boost slowly builds up. A long enough hill will most probably get it to 0.8 bar of boost, whereas in my TD5 it will quickly go to 0.8 to 1 bar at a small throttle setting.
Std map on the ecu, turbo checked, maf checked, map cleaned, waste gate actuator ok, throttle inputs ok etc. May be boost controller, but power is way down and no throttle response, no turbo lag, just like no turbo for a long time...

I don't understand what you are saying...

He's just poking fun at the diesels - poor guy, wedded to a V8 -we should pity him
I think Eevo is trying to say TD5's lack power! obviously an envious v8 driver!
Anyway back to your question. Does it rev freely in neutral no load? Turbo hoses?
has it suddenly died in the bum or is that not known? Air filter clean and intakes clear?
The exhausts on TD5s are pretty free with few places to block. The silencer is able to be unbolted from the rear pipe, if its original, Aside from that yes unbolt from the turbo and try. It could all so be the MAF? Lots of things other than a blocked exhaust could be causing it to do those things.

Lack of air or lack of fuel....
The Intercooler hoses are known to collapse internally which will strangle the performance.
On petrol engines I've also seen the same symptoms when the fuel filter is blocked.

Broken record here but I'll say it again: "record fuelling inputs to file while doing a test drive and post up the CSV file."
The ability to record inputs is the main feature that makes the Nanocom better for diagnostics than the Hawkeye. You should use it.

Mate, for a start what is a record?But seriously, this is the first time that I've seen that stated on AULRO. I'll see if we can do that, after removing some other potential causes. This is the first time that I've used the nanocom to fault find, rather than clear faults, so I'm on a learning curve.
