Engine Diagnostic Light & Loud Knocking Xantia 1.9td

[shaunlfc1]

Hi all,

 

My 1998 1.9TD Xantia with air con was fine until I went too leave work tonight, the engine diagnostic light comes on and stays on and the car sounds horrible, well a loud knocking noise. It seems to start and idle fine but the noise is horrendous.

 

I was told to change fuel filter and put in some injector cleaner, as it might be a blocked injector. I've done this but no change but I didnt run the car too long so was wandering if I've not given it enough time for the cleaner fluid to get to the injectors!

 

All your advice would be hugely appreciated.

 

Many thanks,

 

Shaun

I guess Shaun has this sorted by now as his post was over 4 months ago.

 

This sounds like the problem I had on my 1997 1.9TD SX about 8 years ago. It turned out the cam belt had slipped/jumped a tooth. In my case this was because the edge of the auxiliary belt had broken up and some of the debris had got under the timing belt crankshaft pulley allowing the timing belt to slip.

The "event" was fairly obvious with the engine light coming on and enough additional "diesel" noise to make me stop straight away and have a look under the bonet. The whole drivers side of the engine was covered in long fibre strands from the chewed up aux belt which was now missing a few mm down the engine side.

I continued to drive it carefully doing about 200 miles over the following week or so while I thought about what to do about it. (The handbook said go to to your dealer ASAP, not stop the engine and get it towed to a garage). Then one evening after work I found it just wouldn't start. I guess it had slipped another tooth.

Cam belt and aux belts replaced and all was well with no other damage.
