Yes the tray under the bonnet has been sealed after they did the injectors. I was told by Harretts that they were told to do this when Trafics were in for service. Wether or not this makes a significant difference to the galvanic corrossion of dis-similar metals or not. But with research and development of someone like Renault, I find it difficult to believe that they assemble engines with aluminium alloy, steel and copper with these injectors. It's some thirty years ago I first experienced a steel bolt bolt in an aluminium casting of a Thule roof bar, not to mention steel brake pad pins in alloy caliper castings.

After Renualt got a bit of one injector stuck, got them to call Tony _ http://www.apautodiagnostics.com/injector-removal-service who I was originally wanting to do job.
Tony removed the injector end - vehicle now back together and running great again.
Have a look at his web page - I would certainly recommend him to anyone with an injection issue.
Thanks to all for help.

Hi,
just back from a visit to local Renault main agent confirming injector 2 being faulty. So Foxwell - P0202 was correct.

As recommended - decided to have all four replaced. I was shown the corrossion mainly around 2 and told of possible problem getting injectors out. He put a penetrating oil on and said to leave it for a week or two.

Not a welcome expense, but hopefully that'll be it for a while.

Thanks Dave. Did you do any testing for resistance on the old injectors to prove things to yourself? Suppose if it worked you wern't bothered.

Is 50k miles an expected time for injector failure. Previous technology for injectors in Peugeot 405 > 176K miles and Xantia > 150k miles without issue.

Is this an actual breakdown of the injector or would some 'Forte' diesel treatment cleaning qualities be a benefit?

Usual diesel problem. Spent hundreds of pounds a few years ago on a Fiat Marea with garage diags, even replacing the ECU. Eventually resolved it myself for £15 - EGR Modulator Valve.

I had orginally thought to give EGR a clean.

I was under the impression that from early 90s legislation standardised ECU diags. I'll take it back explaining view on Renault diags.

It's been raining all day today, will let you know after a clean of EGR.

Thanks

Thanks for prompt reply.

It starts and idles fine, as well as I'm aware. It is usually on harder acceleration. It seems to pull away OK, on realatively hard acceleration it either feels to miss a little or dies - really lacks power, but comes back immediately. One or two red lights come on but so briefly I haven't caught what they are.

On the Foxwell, is this not really worth purchase?
