Smokey back end

[ronnie939]

HI,

We have a tdi sport 06 plate 2 months old and it seems really really smokey, there is a lot of smoke even when under 1/4 throttle.

Now I had the FR TDi and that was NEVER this bad...

Any ideas?

Thanks

Ronnie

~No one had this problem then ?

could be a boost leak i guess, at two months old its gonna go back to the dealers i would say.

I've seen loads of 2.0 TDis smoking , from golfs to Audis. They all seem to do it. Mine not so much now as its been remapped. If performance is not affected, its probably just a characteristic of the engine.

Had mine for 8 months and done 21000 miles, mine smokes quite hard when accelerating but okay the rest of the time. I am booked in for a service next week and will ask them to check as it also goes through quite a lot of oil (1l every 5000miles).

Thanks for the replys guys.

It's just sitting behind the car watching it pull away not very quickly it can smoke, As we have had it from new and she does look after her cars, I was a little worried that it was a bit too smokey from standard.

To be fair it does pull really well and around town it more fun to drive than my Focus ST2.

I find if you use supermarket fuels they tend to smoke a lot more than your Shell or BP ultimate type fuels. The smoke is also darker...Try using Shell Extra or BP Ultimate and see how it goes...

I see ... that could make the difference.

I dont have a new leon, but i do have a very fast diesel ibiza. With the supermarket fuels, i found that it did smoke a hell of alot, under load and usually towards the top of the revs etc. Now the past 3 tanks i have sed texaco fuel and it still smokes under full load in 1st and 2nd but not as much as it used to. Try differnt fuels, and also try just giving it a blast through the rev range. may just be a build up of carbon if it doesnt get driven hard occasionally.

That explains everything. Just noticed mine has been quite smokey recently. I drove over 1000 miles in seven days and have used super market fuel for the journeys. I had to wash the car this evening as the bumper and reflector above the exhaust were sooty black. It's back to better fuel for me.

Yup definately the poor fuel I reckon...post us your results when you have put 2-3 tank full of good fuel.

if it's smoking under 1/4 throttle and standard i would say a little boost leak, (jubilee loose or socket connector) take to dealers ask them to have a look,
it's such a common thing,

thing i worry about on boost leaks under boost its throwing air out, but at no boost i.e under 1500rpm is it sucking dirty air in

when my cupra 160 was standard no visible black smoke under load.

 

[ronnie939]

That was a great idea mate, Will get it to the dealers to check it.
