Turbo R.i.P

punisher5112

Hi fartman sorry to hear that.

The last poster thinks it's ok to just jump in engine cold and drive off.
I don't mean start car and leave sitting there for ages but just the 1 or 2 and I go by when the auto choke cuts out and revs level out.

The oil will not have circulated properly if you do this.
Also changing oil and filters on time or even slightly before service is due is good to prolong life.

I also know the gearbox will not warm up sitting there but thats why I said don't drive hard from the start as to let that warm up.


Turbo's can be very tricky and sometimes go no matter what but if looked after as best as possible it does help.

Cheers mate for the advise ,I will be doing what you said with running the engine for a few minutes before setting off for sure .:)

If you're referring to me, I don't think that, I know it. Otherwise the manufacturer would have a line saying "please sit in your driveway for 2 minutes until the car is warmed up" in the owners manual.

You can be damned sure it aint there!

A car in use will heat up more quickly. More revs = More combustion = More heat being generated. You don't need to take the piss, but normal driving.

Also you may want to check what decade you're in before giving out (bad) advice. Unless your car still has a carburetor, it doesn't have a choke.

You're only wasting your time and fuel sitting there. But OFC everyone's an expert on the internet.

Can't recall what car you are referring to,

But in my A4 TDI it is not a good idea to sit & idle as it would never warm up therefore it's pointless.

However, after a journey it is a good idea to sit & idle for a minute before switching engine off especially if the turbo was been heavily used.

Does your A4 have an after run pump ? listen for a whirring noise from the lower front grille after switching it off, this pumps coolant around the engine and turbo for 10 mins after the ignition is turned off,a sort of OEM turbo timer if you will so no need to leave the car idle after a journey, My bora had one, as did my A4 and my S3.

Even still a bit of mechanical sympathy is called for , you shouldn't drive it hard as your near the end of a journey.

Thanks for the info,

I never knew such a thing existed, will keep an ear out for this "after run" pump.

It should be fitted to every car in fairness,such a simple little thing could make a difference.

electric radiator fan runs on some cars for a few mins after engine is shut down but pumps are mechanical driven of engine. When engine is stopped so are the pumps.

Normally, yes. What tossy has just explained is VW seem to have installed AFTER run pumps which function AFTER you turn off the engine.

The clue is in the name 'After run' see below \/
