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?

My e-mail adress is: TDISLine@yahoo.com

SOURCE: cream gunge on oli rocker cover

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.

SOURCE: car smoke white when idle and nothing when driving

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.

2002 SAAB is releasing white smoke out of tail pipe and stalling


White smoke out the exhaust is a sign of either water in the fuel or coolant being burned with the fuel. Observe if you have any coolant consumption and if not, wait until your tank to empt and filled up with new fresh good quality gasoline and you will be allright. If you have a coolant consumption you will need a tool to pressure test the coolant system and find where is leaking. You can purchase it at Harborfreight tools. Could be head gasket, Throtllebody gasket, intake gasket and others... Good luck.

Turbo / Intercooler Hose collapses


Most probably your hose is the problem, does the exhaust smoke more than usual ?
If it does then the collapsing hose is reducing the air volume that your engine needs. Your turbo is trying to drag air from the intercooler rad the hose collapses, reduced power.
If you can't get a new one before Christmas try taking off the hose and pushing a hard plastic pipe inside it, if there are bends in the pipe cut the plastic pipe into halves and feed it in. may help. But you really need air into the engine.

I have an Audi A41.9 TDI 1997 and it is coughing up black smoke which comes out of the exhaust pipe. On the motoway, while trying to overtake a car a puff of black smoke came out of the exhaust pipe and...


There are several possible faults:
1. Pressure sensor is faulty (it might come up on diagnostics as if it was working fine, but it shows the wrong manifold pressure).
2. Either one of the boost pipes/hoses or the intercooler have a hole somewhere.
3. Turbo's actuator is stuck.
4. Vacuum hose is damaged which goes in to the turbo actuator.
5. Control valve for the turbo actuator is not working properly.

Audi A6 3.0 tdi Quattro 2005, glow plug light comes on, limp mode


16619 -Engine boost condition - Limit not reached. Check intake hoses/ connections for leaks. Check Turbo charger waste gate regulating valve/ waste gate working correctly. Must move freely when accelerating, won't achieve full boost if waste gate sticking open. Check Turbo impeller turning freely, oil feed pipe for turbo can get blocked causing impeller to seize. Engine compact, not easy to access these components.

2006 jetta tdi oil change


Consult the Owner's Manual, or view the oil specifications on the fill cal or dipstick (usually the fill cap) located under the hood. Depending upon mileage you may not want to vary from manufacture specifications, or risk voiding your vehicle's warranty should any remain. The VW TDI's are typically high maintenance engines. I would strongly recommend staying with the manufacture's oil specifications, and do not overfill the oil in your vehicle.
