For the second time my car has blown/split this hose. Its the hose direct after turbo to intercooler.

 

The car does not give me any faultcodes on this fault yet but last time it did.

 

The hose did split when i put car in sport and kicked to pas cars.

 

What should i look at?

 

The turbo pressure valve gets hot like crazy, is that normal?

 

Is the turbo on its way? 

 

 

 

 

Is the turbo overboosting and blowing the pipe perhaps?

 

Are the turbo vanes seized? Try pushing on the actuator and seeing if they move.

 

My turbo vanes were seized up and kept going into limp mode (overboost protection), the effect was quite obvious and a VCDS scan showed up the problem. Doing the DIY oven cleaner trick sorted mine out, it's been fine ever since, over a year ago since I did it.

I have had my turbo looked at and I can move the axel like 2-3 mm up and down but that should not be a problem for overboost i gues.

I would like to try the mr muscle cleaning but my motor, the BMM, i dont understand how i should do it. And i also gues that since its i diesel with dpf, the heat from that should burn of the most sluggish stuff?

All the info videos and instructions here on forum is not for my motorcode.

 

What do you think about the turbo pressure/vacum valve then, should it be so hot that you burn yourself if you put your hands on it?

 

The car has just passed 29 4000 km, its a regular long trip car.

 

 

I had one of those go a few years back on our BMM on a trip over the Pennines fully loaded on the way to Birkenhead to catch a ferry.  My understanding from the garage that repared it in Belfast when we finally got there was that it was not uncommon and was partly due to degradation of the hose over time.  I believe a modified or tougher rubber or silicon hose was fitted as a replacement.

I would have no problem with 1 hose splitting after 12 years, but that another one splits just 6 month later, at the exact same place? Bad luck or some other fault.....?

if it has gone after only 6 months I'd suggest a manufacturing fault.  The part should have a 12 month warranty on it so should be replaced by whoever supplied or fitted it.

 

In terms of other things I have a feeling my actuator moves more than 2-3mm so the vanes could be sticking, which might tally with overboost and your comment re the release valve getting very hot??  Does it move freely or does it feel 'sticky'?

 

I'd try and work it a bit manually and see if you can get some more movement out of it as a starting point and also see if there are any intermittent or pending codes logged.

I mean the electronik vaccum valve that is geting extremly hot, some call it the N75 on vag cars?

 

I can move the acuator like 1-2cm, I mean that i can move the turbo axel inside the turbo 2-3 mm up and down but not in and out. Make sense?
