SOURCE: turbo over boost on audi
I can help you to fix this problem. "Fault code: P1557 - Turbo Boost pressure control exceeded"
But I need some info from your engine:
- what type of engine do you have (engine code: ex.ALH, AJM, AWX, ...) or power in kW (PS)
- how many km (miles) are your car?

Dont panic. The creamy deposits youve found is where water/moisture is mixing with your engine oil. This can be due to any manner of reasons. Firstly, oil change intervals are always increasing which is not necessarily a good thing as it puts even higher demands on the oil between changes. If most of your journeys are local/town trips, this makes the problem worse as your engine simply isnt running as its designed to at varied speeds, up and down motorways and the like. Is your cooling system thermostat working correctly? This is a very important component in any engine, as its function is to maintain a constant working temperature. If your temperature gauge fails to read a normal working temp, it could be your thermostat has become stuck open? What this means is your motor wont be running hot enough, which will in turn develop cold spots and condensation around your engine, hence the cream sludge. Give your engine a good quality engine flush prior to changing the oil and filter. Top tip, dont go for a cheep grade oil to try and save a few pounds, in the long term its uneconomic. Many engines these days are turbo charged and bearing failure due to poor quality oil is a very expensive lesson to learn by, I can assure you of that. One other thing to check is your coolant level, has it dropped at all? There is a slim possibility there may be cross contamination between the two fluids, possibly due to a cylinder head/gasket fault. Is there a lot of pressure when you remove the coolant expansion tank cap? if not, your probably in the clear. I hope this advice is of some help? Good luck.

First, take it back and give them a chance to correct there repair abilities or lack of knowledge. Hopefully they will not want to charge you. Find a good repair facility before you need one.

Engine also smokes when car driving if turbocharger still faulty. Did you change the engine timing belt (the timing belt kit) meantime? What about engine oil consumption? When engine glow plugs (one or more) burnt then engine exhausts white smoke at idling. Also white smoke at engine idling when water is still present in diesel fuel.
