Head gasket is compromised.

If no fuel is getting to the plugs the inyection system is not working. Check for spark in one spark plug. If you don't have spark that is the reason why the injection is not working. When there is no spark, the ECM or injection computer won't work because it needs a signal from the coil, as s proof of spark..

P0234 DescriptionThe boost pressure sensor responds to pressure changes in the intake manifold. This pressure is created by the turbocharger and changes with accelerator pedal position (APP) and engine speed. The engine control module (ECM) uses this information to assist in diagnosis of the barometric pressure (BARO) sensor and to provide engine overboost protection. The boost pressure sensor has a 5-volt reference circuit, a low reference circuit, and a signal circuit. The engine control module (ECM) supplies 5 volts to the boost pressure sensor on the 5-volt reference 2 circuit, and provides a ground on a low reference circuit. The boost pressure sensor provides a signal to the ECM on a signal circuit relative to the pressure changes. The ECM monitors the boost pressure sensor signal for voltage outside of the normal range. The ECM calculates a predicted value for the boost pressure sensor. The ECM then compares the predicted value to the actual signal.Read more: http://engine-codes.com/p0234.html#ixzz2e2DssWbP

Supercharging system using the exhaust gas energy and improve the efficiency of the engine air intake, make more air (fuel) participate in burning, so he can improve engine output power and output torque. General in order to improve the density of air intake and lower the temperature in the thermal cycle starting in turbocharger gas end to connect a cold air for cooling.auto diagnostic tool

bad turn signal switch

Go to AUTOZNE,they will scan it for free and tell you what's wrong.

HelloThe Engine and Automatic Transmission (not applicable to manual transmissions) in this vehicles drive train are fully electronically controlled by a computer called the PCM and TCM (Power Train Control Module, Transmission Control Module). When a problem like this or other drive-ability related problems occurs the computer stores a record of the problem (there are of course some exceptions to this, like the fuel pump, engine coolant temperature sensor and MAF sensor for instance) in the form of a fault code in its memory, to read these fault codes you must have the systems memory scanned with a special tool. Once the fault code(s) are read you then must perform the appropriate diagnostic testing to find and resolve the problem(s) DO NOT REPLACE ANY PARTS UNTIL A TRAINED TECHNICAIN HAS DIAGNOSED THE PROBLEM TO AVOID SPENDING YOUR HARD EARNED MONEY ON PARTS THAT MAY NOT CORRECT THE PROBLEM. Also always check fuel pressure for correct spec for your make and engine type.

The dealer should give this info.

If you are not seeing a coolant leak on the ground, and you are adding coolant every week, chances are the engine is burning it out the tailpipe. That would be from a leaking head gasket or other internal problem with the engine.

Thought i would reply to your lonely thread. I had to replace the aerial on my last 159 as it was broken when i first got it, i replaced it with a bee sting type off0 ebay didnt cost much was worried it might be a bit rubbish but turned out to be pretty good. As far as i can remember i managed to remove the rear end of the head lining (below the aerial) by popping off the two poppers holding the headling to the roof i then managed to disconnect the cable that connects to the aerial and undo what i remember was one nut that connects to the aerial thread inside car. The job was fiddly but only because i did not want to remove the head lining any more than i had to. but not difficult. without head lining in way it really would be a two minute job.Hope it helpsParts Of Bmw.

try new reley dean.

you need to undo all the screws holding the mirror too

You need to be careful about buying a Volvo unit that has no code.

The reason for this is that many Volvo radios cannot be easily decoded using the serial number alone. This means that whilst it is possible to obtain a code it is going to be more involved and expensive.

If you post up the serial and part numbers of the radio I can give you some more specific advice as to what can be done with this particular unit.

Thanks.
