Ok read in another thread about using redex or similar to help with rough idle and suchlike.
Got my 407 back tonight and they reckon they tested the injectors and one was giving off a dodgy reading. So they cleaned them.
Didn't get a really decent drive home to test for pull back but I think after reading other threads that this redex wouldn't harm to try as well?
My question is what the hell is it and which do I need? Mines a 407 se 2 litre petrol..04 which would be the EW10 engine.

Can someone link me a brand?
This is the stuff I presume?

Guess I need the injector version?
Never used it before so any nods in the right direction appreciated. :thumb:

It'll be fine, quite safe. Run the tank low-ish and chuck in a whole bottle of Wurth petrol injector cleaner.

Where are you located?? You may be better off to get one of the guys on here to plug Planet into it and have a look with you.... may help to save you time and hassle :thumb:

In Norfolk, about 20 miles from Norwich. Have a few local garages that can read the ecu for the princely sum of about 30 quid but can't find anyone with planet.
So if there is anyone about I'd be pleased to hear from them! If only to have a more accurate reading done to help the garage.

Yeah that's a good hour away.
I'm 20 mins from Norwich.
There is a local French car specialist about 5 mins away but they won't confirm if they use planet or not! And they want 40 quid just to read the ecu anyway!
Love the car, it's absolute bliss to sit in and drive. This problem is a niggling thing to be fair, but with it under warranty I'd like to get it sorted!

Well have to report that the trusty Enterprise is actually running superbly well! Put half a bottle of redex into a half and of petrol, also sprayed a good dose of wd40 to all connections of the injectors. Did a couple of fairly long runs and she didn't choke or pull back once! So either the redex is a wonder cure or the wd40 is! Lol!
Still got depolution light on so need to get the codes checked, but the fact that redex/ wd40 seems to cure the main fault hints at something that isn't too terminal! :)

Gave mine a top-up of oil 2wks ago when the light come on, and ever since then, its been running really smooth... no more hesitating/lurching at 1700rpm.... touch wood, it stays like it :thumb: .... however, I have no idea what the importance of topping up the oil would have made to it, as it wasn't even at the minimum level :confused:

I had a small service done on car, filters, oil, battery changed. used up one bottle of diesel injector cleaning additive, and it seems to have done it. happy :)

iirc it was wynn's additive, they didnt have anything else.

well started mine through an open window yesterday to test the idle...you could smell petrol when it was idling roughly.
from what ive been reading thats a classic sign of an injector failing. so whilst my coughing and pulling back is certainly improved it would still appear there is a fault there somewhere and most likely an injector.

Put in a descent injector cleaner like Forte to 1/2 tank fuel and give it a Italian tune up !

If no fault codes show and no warning lights show then this is worth a try!

Trust me I have 35 years trade experience and my 407 has no warning lights on and it never has! apart from a low tyre pressure one(when it 's low on pressure )

Already has depolution warning light on it with various code for egr,map and ignition. New egr fitted, also map sensor and garage had injectors cleaned as well. Depolution light came back on with pulling back under low throttle when I drove back from lat garage visit.
Italian tune up plus redex/ wd40 has resolved pulling back, but still got depolution error and very rough idle plus fuel smell on start.
Hence seeing f I could diagnose injector without access to Peugeot planet.

Smell of fuel could be seals on injectors.

you could alway bite the bullet and go dealers for a diagnostic, get a full techies report :thumb:

yeah...they put their masks on, held a gun to my head and offered me the pleasure of 50 quid for the service! LOL
im just "fiddling" at home til it goes back to the garage again to be sorted. loathe to pay money out for something they should be doing under warranty so just trying to figure out where/what to look at off my own back still :)
