TDI questions

[thegooddie]

Hey guys, I just have a few questions about TDI's. I have a MK4 Golf TDI and I've noticed that it smokes like crazy. I got a diesel injector cleaner that was supposed to help get rid of some of the smoke and help my gas millage...turns out that it didn't do anything for the smoking and the gas millage got worst. Any ideas about what to do there?

Also, time is coming up for me to do my first oil change for this car too. Any suggestions on best engine oil and what oil filters to get?

Thanks

Re: TDI questions

Since I've owned the car, I've never had a TDI before

Re: TDI questions

yeah they go forever. I just take it to the dealer (leased car) and put in what they recommend is best. if it fucks up they're liable.

Re: TDI questions

TDI is stock?
Smokes all the time or just starting? or just accel?

How is the air filter? A TDI with no air with smoke pretty bad and get bad mileage.

these gentlemen are far more knowledgeable than I, on the subject. Heed their words.

Re: TDI questions

Yah, check the air filter and snow screen. It really needs to be put on Vag-com and logged to see if something is wrong.

You just missed a smoking deal on Rotella at CT ($22 per jug). I would suggest Mobil TDT at Wallyworld.

Re: TDI questions

The car is chipped so not completely stock. It sometimes smokes on start, as far as I can tell mainly smokes while accelerating.
Any suggestions on oil filters?
Thanks again for your help. I'm going to look at the air filter and snow screen tonight when I get home.

Re: TDI questions

Sounds kinda like normal. How much smoke?

Re: TDI questions

not really sure how to describe it. but when i step on the gas and the revs build up, i can see in my rear view that there's a cloud of smoke that's left behind

Re: TDI questions

sounds normal....especially in the dark with the headlights on in the car behind you.

Re: TDI questions

I'd say smoke is normal, heavy smoke in chipped alh engines is ok from what I've read.

Re: TDI questions

If the car is chipped, then smoke is normal. The ECU is just dumping more diesel in the engine through the injectors. Thats how you get more power out of diesel engines..more fuel=more power. This is not the same with gasoline cars unless you increase the air your engine breaths ie. turbos.

For oil I use Motul in my TDI. Filter, whatever is available. If you can get Mann filters they are good. Make sure you replace the 2 O-rings that come with the new filter every time!
