Redex for a Focus Diesel?

DazedAndConfuzed

Afternoon all,

I've just had my Focus 07 diesel go for the MOT and one thing that's come back is they recommend I run some kind of fuel cleaner through it as it's failing the emissions test. Is redex the best for this?

Thanks

Yes, or Millers Diesel Power Ecomax.

I think diesels have a "smoke test" rather than emissions like a petrol. Discussed here -

They suggest it could be caused by a duff batch of fuel in addition to recommending redex and Forte treatments to help.

Redex should be easier to find locally - not sure if the forte stuff is better (http://www.ebay.co.uk/itm/FORTE-ADVANCED-FORMULA-DIESEL-TREATMENT-400ML-/190545359170)

That and take it for an Italian tune-up.

Find a quiet fast road (motorway is best...good luck). Choose a lower gear and floor it to the red line a few times. Stop when the piles of smoke stuck to the insides of the exhaust system stop coming out of the back.

Do that once or twice each month and laugh in the face of emissions tests...

I use this stuff just before my MOT (and I struggle to get mine through)

Is Redex ok for a TDCI or would it be better looking for a specialist injector cleaner?

The "Italian tune up" does require some careful planning and an adequate warm up - plus eyes in your mirrors;)
Warm the car up until you reach mormal working temperature, then take the car through the gears NEARLY to the red line each time - obviously this will mean keeping the car in third or fourth gear so that you do not break the speed limit;)
When you have done this, gradually do a warm down, by reverting to normal driving (not applicable of course if you always drive like this:D) in oder to cool everything down and let the poor thing recover from its ordeal.
On the way home, take it nice and easy, and do not switch the engine off immediately if you have a turbo engined car.

What he said...& OP, if you think all this is a load of speculative tosh; I also failed an emission test on a diesel once and took was told to take it for a 'good hard thrash' by the tester.

Came back and passed just fine. Particulates do get stuck to the inside of diesel exhausts and this does remove them before the test.

As long as it's diesel redex of course.

As a long term thing. Every fillup it may or may not improvematters.

Plenty have been pulled from the market for false claims.

Using it just before the MOT is unlikely to do anything. If it does work its not strong enough to clean all the deposits off in such a short time.

If were stronger it would probably damage seals etc.

No need to redline it but fairly hard acceleration through the gears the week before the MOT will do it wonders.
The italian tuneup as they call it.. Thrash it. But dont kill it.. No need for high revs. High boost levels to blow the cobwebs away.
And a decent run on the motorway to make sure it gets hot.

Exactly what he said - I do it quite often if I've not been driving the car but the Better Half has (she has a 12 mile commute, fairly low speed/town stuff) and the !"£$ that can come out of the back is quite scary. Wouldn't bother with the Redex/injector cleaner stuff
