First ever MOT fail!

All Brake pipes excessive corrosion. The joys of living in the northeast of Scotland. And Exhaust emits an excessive level of metered smoke. Boo Hoo. First ever Fail it had to come at some point i suppose.

Unluky mate, never mind, salmon season started. What you gonna do about emissions?

The guy who Tests it recons some sort of additive in the fuel and and give it a good hard boot. Clears the crap out apparently, we will see!

What engine is it? My 19j failed for that last year and was told the same, £30's worth of Millers additive later it was still the same but the tester passed it any, been told sticking a load of veg oil in improves the emissions just as well

Td5 How Much veg oil?

i feel your pain
my tester always told me to put redex in a give it a good frashing first

has it had a service recently? if not give it one. go blat it down the road for an hour or so so the engine can burn all the crap.

my 300 sailed through crazily low with veg oil in the tank. 20-30% would do.

do a 30% mix and fill the tank 1/3rd up then you can fill it up with diesel if it doesn't like it

Probably overdue an oil change. Will see to it Will give the redex a Go if that fails.

My Peugeot failed it's M.O.T. last year at a Halfords M.O.T, station. The tester gave the same advice and sold me an additive that is stocked by Halfords, seem to recall it cost about twelve quid. Added it to the fuel tank and booted the car up and down the nearest bypass four or five times keeping it on the boil and using lower gears than I normally would. Then straight back to have it tested again..... passed easily. Now this year I have decided to stop using Scotsmans overdrive, and work the engine more. It's going to cost more to run but a couple of tanks of fuel before the next M.O.T. I will fill up with BP Ultimate (about 10p a litre dearer than regular diesel ) and the see if I pass first time.

....same happened with 300 tdi....tester stuck some egr cleaner through it and it sailed through...I have a blanked egr so it must have just generally cleaned the intake enough

Make sure well warm before you take it in and remove air filter

Take your air filter out for the mot

I also go for at least an hours drive prior to mot and rag it to get everything hot and burnt off. Also stick some injector cleaner in for a tank beforehand.

Didn't do any of that this year though and got worst smoke so far lol

Thanks for all hints and tips guys. Retest fri will let you all know how it goes.

dont stick veg oil in a td5,they dont like it

Good luck for Friday..

Could be a dodgy MAF something like that causing the emissions. You might need to get it scanned if the additive trick doesnt work.

oil change, filter out, fuel addative and an italian tune up, bounce it off the limiter in 2nd for 1/4 mile.

Mine failed on the Emissions (300 Tdi), I stuck a load of Veg oil in it, some Redex and a couple of litres of petrol, THEN gave it a good thrash before the re-test, it sailed through, but I'm not sure which bit worked and which didn't, I'd been given a few things to try, and just thought I'd try all of them at once

Changed all the brake pipes. Now all copper. £8.95 for something called Diesel Magic put in by the bloke that tested it. We once again have an MOT certificate Thanks for all your help and suggestions guys.
