HELP!! Suspect turbo issue

[Erlingtheelder]

This is a job where the labour cost is high compared to the part cost. Something to consider, it is after all remapped.

Fair point. Spam and economy beans ‘till Christmas at this rate!!!

Luxury used to dream of spam. Monty Python anyone?

According to 7zap, 18mm to 8Z-2-027 000, 12mm from 8Z-2-027 001.

Thanks @RAB So with this chassis number;

12m?

 

[Guest 4123]

18mm I think. 008309 < 027000.

That would make more sense!

But if you are replacing the intercooler , all new intercoolers are built to take the SMALLER Mass Air Pressure sensor.

Thanks

So in summary, I’ll change to the Map sensor pretty much regardless?

 

[audifan]

Just make sure you get a good quality one.

 

[Erlingtheelder]

I’m guessing either an Oem or Bosch one. Any idea on a part number as struggling to find the different sizes being terribly obvious on ‘the bay’ et al.

No2 in this diagram. Check the part number has not been updated..

If you click on the "i" then aftermarket you can see a list of manufacturers part numbers.

You could use a 12mm M to 18mm F adaptor?

Having just seen this thread ‘revived’ in another post, I felt compelled to update it.

I should add that my father and I replaced the intercooler with a donor one kindly donated by @Proghound. Not the easiest job in the world but also not the worst either. The worst bit was removing the bumper etc tbh.

We suspect a contributor to the failure was the clamp breaking which supported the pipe going into the intercooler.

Im pleased to say that to date the car has done a further 15,000 trouble free miles since. ?

Yes I have commented many times that I believe a broken or missing turbo air outlet pipe bracket puts extra strain on the lower inlet fitting on the intercooler. This then vibrates / flexes more and the end cap cracks and splits open to spit out the seal. Boost lost and limp mode.
