Golf 1.4 TSI

[WILLWALL]

Hello,i Own A Golf1.4 Tsi 170 On A 06 Plate With 5600mls,took It Back To My Local Dealer Last Week Cos Of Poor Performance; Turbo Gargiles(think Thats How You Spell It)and Lack Of Power But When Turbo Sounds(whistiles) Right The Car Really Does Go Well!!!!!they Did A Mapping Update Off The Internet And Said It Should Be Ok.now When Pulling Hard Through The Revs The Car Surges Through The Range And Turbo??? Problem Is Still There Sometimes.

hmmmm well theres a little cause for concern.
Was ur car a demo model or did u buy from new?
I have one coming in in de next 3 weeks,any problems

Thanks

HELLO,ITS A EX VAG CAR BOUGHT WITH 3200MLS FROM A VAG DEALERSHIP IN SWANSEA.DURING MY VISIT LAST WEEK THEY DID ADMIT COS THE ENGINE IS NEW THEY CAN ONLY GO BY WHAT THE LAPTOP SAYS,KNOCKED MY CONFID I USE SHELL V POWER SO THEY CAN'T TELL ME I'M USING POOR FUEL.

I have been told by many ppl that it really needs to be driven delicately for the first couple of thousand miles as like any other new car i suppose,but it being a demo just think back to when you test drove the TSI.I for one gave it a fair bit of welly down the M50(Dublin)
Surely if everyone that test drives and gives the motor a bit of stick before the engine is run in it will have some sort of effect?
Maybe im wrong here?

First couple of thousand??? - not really! For the first 600miles, it does need carefull running in; no more than three quarters throttle, and no more than three quarters engine revs (no towing either!!!). From 600miles, upto 1200miles, you can then start to gradually increase throttle opening and engine revs, upto maximum, but without any sustained high speeds or high loads. From 1200miles, you really should open her up on a regular basis - indeed many would say you should drive it like you stole it! There is sound engineering principles behind these theories, along with evidence of problems arising from not giving it a good caning!

but it being a demo just think back to when you test drove the TSI. I for one gave it a fair bit of welly down the M50(Dublin). Surely if everyone that test drives and gives the motor a bit of stick before the engine is run in it will have some sort of effect?

Sadly, that is one of the real downsides of purchasing a demonstrator, and a snake pit which I have previously fallen into!

For anyone who is considering purchasing a demonstrator, I would say it is vital to build up a rapport with the sales staff at the intended dealer, and actually monitoring their general care for the cars they move around on the forcourt. Also ask exactly how the initial 600miles was covered - did they hand the keys, willy-nilly to every Tom, Richard and Harriet who walked through showroom doors from day 1, or did they ensure that only the dealer staff carried out the initial 600miles???

Maybe im wrong here?

Observations of wise caution - I'd say

Back to the original title, could anyone with experience of the 1.4 TSI 140 pop over and help this chap out please;

Much obliged

I drove a TSI 140 and loved it so much I bought one, which I pick up on Sunday. It's perfect for me because I need a car with a small, economic engine, but with a bit of grunt when I need it. I tried a 1.6 FSi and couldn't believe how gutless it was, and as this is only a 2nd car for me I didn't need to go the GTi route.

As soon as I've picked it up I'll post up my experiences/thoughts/opinions.

No need for Chavtastic turbo timers. The engine management ECU instructs an auxillary electric coolant pump to run after the engine is turned off. The turbo is actually water cooled.

Why would you pump the coolant after the engine is switched off? Turbo timers keeps the engine running to allow the oil to circulate and cool gradually and so stop it from depositing in and restricting the oilways.

conventional turbos are oil cooled, meaning there is a need to allow the oil to cool, eg using a turbo timer, to stop turbos and bearings seizing up.

i presume from what TT is saying, the (TSI) turbo is water cooled, as opposed to being oil cooled, hence there is an aux pump to perform the cooling, after the engine is turned off, allowing the turbo to be cooled down properly without the need for leaving the engine running and/or having the need for turbo timers.

A lot of the heavily modified Passat boys either calm their driving down as they near their destination or simply leave the car running for a bit as they unpack - obviously if you park on a street that isn't an option.

In what car?

...meaning there is a need to allow the oil to cool, eg using a turbo timer, to stop turbos and bearings seizing up.

All turbos are lubricated with oil, and all turbos get very hot, so if you stop the engine when the turbo is hot the then this heat can burn the oil onto the bearing and create deposits in the oil ways on the turbo.

I agree - this is the best advice.
