Potential Injection Pump Problem

[PhilH]

Hi Guys,

 

I'm getting a metallic knocking noise on idle when cold. It seems to be coming from the auxiliary area. I found

You Tube vid ad at abotu 46 seconds this is similar to the noise I'm getting. 

 

It occurs a few seconds after starting the engine, once the revs have dropped down a bit. Is the Injection Pump a common problem and is it easy to change? If this was the problem would there be any fault codes logged as I have nothing other than an immobiliser fault which seems to pop up now and then.

 

The noise reminds me of when I had a Mondeo TDCi and the crank pulley was rattling about. My first thoughts were perhaps a pulley of some kind. I have also noticed that the aux belt is quite badly cracked and needs replacing. I can't see how a cracked belt could be the cause though.

 

Any thoughts or comments would be appreciated. 

 

It's not DMF by the way, dropping the clutch makes no difference.

 

It's a 130 AMZ 1.9 TDi btw

Your engine doesnt have an external injection pump. Each injector is its own pump (PD - Pump Duse).

 

First check the auxillary belt tensioner isnt jumping up and down madly as this indicates a seized alternator clutched pulley (common).

Brilliant, thanks. Will check that out. No wonder I couldn't find anything about injection pump problems lol

The more I read the more I think you're right. I'm not sure I fancy it myself either!

 

Any ideas of replacement costs?

So the wife has just also mentioned that yesterday when she started the car she had a flashing warning light and "Engine Workshop" displayed. This happened for the duration of the journey and hasn't happened since. No fault codes though.
