Scirocco smoking quite badly

[jacko17]

Hi all,

I've got a scirocco 2.0 tdi 170 bhp, i bought it about two months ago and after about a week it started smoking but due to all the cold weather i didn't do anything as i didn't know if it was anything to do with condensation, The smoke is a light grey/white colour.

So i gave my dad a lift to newquay airport on Sunday and on the way there it was smoking when accelerating or going up a hill its smoking quite bad. Once i got there i turned my engine off and left it a couple of seconds and set back off, Weirdly it stopped smoking on the way back? any one else had any problems like this? not sure if it could be a sticky EGR valve or the dpf need cleaning.

I've checked the oil cap and its fine and been keeping an eye on the coolant and all are fine..

Thank for any help.

They do put out a bit of white / grey smoke when the DPF is performing a regeneration. So if it's not happening all the time, it could be that.

If you switch off the car before the DPF has finished regenerating, the radiator fans will run on for approx 5 mins after switch off. You can normally tell when a regen is taking place as the engine note changes slightly, a bit rougher and the idle increases by a couple of hundred rpm.

Okay thanks for that, haven’t noticed the engine idling and going a increasing rpm, cars going in for a service soon can they clean the dog and egr quite easily? Or is it easy enough for me to do?

Thanks again for the reply

You would only notice the raised idle if the DPF regeneration hadn't been completed by the time you stop. It performs a regeneration roughly every 700 or so miles. If there was an issue with either the DPF or the EGR you would get a DPF warning light or the engine management light. I honestly don't believe you have anything to worry about.

If you are going to be putting your car into VW for a service, personally I would avoid getting the emissions update done, assuming it hasn't been done already. Some owners have had issues with EGR after the update forcing VW to.provide a 2 year warranty from the date of the update to certain emission related components. Despite the warranty, I don't think it's worth taking the risk but you may feel differently, assuming it hasn't already been done. VW will be able to advise if it's been done or not.

Okay thanks again, I don’t use a VW garage so that won’t be a problem. I’ll get a full service done on it
Soon and that might improve the smoke don’t know when the fuel filter and everything else has been change I know it had an oil change about 6 months ago.

Thanks again

Ah that would explain the fan staying on after shutdown that I notice every now and then, could never link it to engine temps so it had me confused.

Thanks Cuprabob

Hey guys, just a quick question here.. So today my TDI scirocco ran a fan for a minute after i shut down the engine, i kinda got worried a little :S + because in one year of ownership that never happened before. I used to hear a lot about people saying bad stuff about Diesel engines because of "some stupid filter getting clogged up" if you are doing short trips.. I have a 2010 Scirocco TDI 140hp with 220000+km on it aaand honestly, with all this information on youtube and from what i have read, i dont rly want TDI anymore :/ and as much as i love this car it brakes my heart to say this.. or am I just making a big deal out of this? o.O

In spring last year, when i bought the car i did quite a mileage, because after all, diesels were meant to be driven long distances, but for the last few weeks ive only been driving it short distances, mostly because its winter and i dont have winter tires, but also because of road salt and all that other stuff that causes rust.. but i do take it for a spin from time to time, just so that the engine gets warmed up, untill today. From today on, I dont even want to drrive it because i am kinda clueless what would be the smart thing to do

My question is, if I go on motorway and "let the engine breathe" for a few miles, would that somehow help DPF to regenerate? and is there anything I can do to get this thing sorted/tested or anything at all without DPF delete, because ive hear that this DPF can be a real problem to the engine if the regeneration is somehow "skipped"(?)

Excuse my knowledge about this kind of stuff, the DPF was the last thing on my mind when i was buying a car.

Thank you so much for your time guys!
