1998 kangoo 1.9 help please injector

[SherpaMog]

Had another look at this today, took injectors out cleaned with petrol all seem ok. Number three has wires going to it and looking down the hole it reluctantly left it's all black and sooty inside. There's a sensor built into this injector how do I test it or could it be whatever is sensing what the sensor senses? Im shit at this, help please appreciated.

Parts darts buy new injector? Anybody got one I could try? 1998 1.9 flat diesel.

I would say that in order to check the sensor is working you would need a Renault specific scan tool/software to give a live read out. If the sensor is not working then an error code should be produced and a 'good' scan tool should pick it up. Autel 702 is a good scan tool - watch for chinese knock offs on EBay.

 

I only say the above, as I had an Audi A6 2.5 v6 TDi a while ago and there is a sensor built into injector 1 I believe it was. That was actually causing it to be a little flat on pick up. I scanned using VAGCOM (VW/Audi/Seat/Skoda and Ford Galaxy specific software) and it came up as G60 sensor fault (Yes shares its name with the coolant) and the only way to replace that was to replace the whole injector being that it was built into the internals.

 

I replaced this and was surprised at the difference it made - pickup and general responsiveness was greatly improved. I had obviously bought the car with the fault already but it did not bring up any warning lights on the dash. Suffice to say that whenever I buy a VAG vehicle or a friend buy one we always take my laptop to scan for error codes as with VAGCOM I can drill down into each module rather than the cheapy chinese scan tools that you can just about turn an engine management code off with.

 

Use a dremel with a small wheel on to clean up inside the injector ports to remove any sooty/black-death looking deposits.

Dare I say the best bet is to find a decent diesel shop, who could test the injector for you. Can't imagine it would be too expensive, certainly worth a go to eliminate it as the problem. 

 

Is it a Delphi injector by the way? if so the name should be stamped onto the part. Along with a Delphi part number, on the metal body. Part number should start something like LCR0...... I'm not sure how prone they are to failure, but they are still available to order at the last time of checking. So there's a reasonable chance of finding one, maybe on eBay etc.. 

 

Hope you get it sorted.

Did you measure the resistance of the sensor?

Link to a VAG forum but it should be similar in principle.

I think I will get it tested, nowhere local though, thanks for the help

try bobbeck fuel injectors...theyre on faceache /google etc

Thanks

There's probably no point in testing the mechanical parts of the injector itself, from reading the symptoms of the needle lift sensor failing it 100% sounds like the symptoms your Kangoo is suffering.

Unplug the connector from the needle lift sender. 

 

Measure resistance between the connector contacts on the sender. Should be 80-120 ohms
