Car boost issue?

[Brandonflowers123]

Hi guys,

I feel there is an issue with my cars turbo.

There is a built in turbo gauge. Under full accerelration it reaches between 0.8 and 1 psi, in any gear.

However today, it is only reaching 0.6 psi in the higher gears, even at high rpm.

What is the problem?
I have two years warranty left, however the dealer is a bit funny with it.
I have been twice, with two problems. They sent he home each time.

I went to an independent garage to get help. They told me what the problems are. I went back to the dealer. And they said "yeah that sounds right" and fixed both problems.

Dealer is stoneacre.

Anyone?

Those boost pressures don't seem very high, should they be 6 and 8 psi or 0.6 and 0.8 bar?

If you can hear any boost leaks under acceleration?

I think it's bar, just me getting mixed up.

The engine sounds normal to me,

Is there any actual text to see if there are leaks?

Boost leak
Waste gate stuck open
Maf sensor
Map sensor

Would any of these show up if I plug it into on of those dianogtics machines?

it might have sucked one of your eye lashes into the air filter and blocked it.

Seems to me like he has just read the gauge wrong thinking bar was PSI and there is in fact nothing wrong with the car. Unless I have miss read as usual.

You may see lower boost in cold temperature, less boost would be needed to make required power. Otherwise take it somewhere to get it checked for leaks.

Have you been to an Abrath specialist? If not, it's the first place I'd go if you think the main dealer hasn't resolved the issue.

It was a cold one today, you could be right. I'll see how it gets along

I can hear a slight whine when I take foot off the gas and the car slows down

Fair play.

This made me laugh

Hmmm I wouldn't say stressed.

My car is 135bhp.

The top spec with the same engine produces 190bhp.

There are people who are running 250bhp
