I cannot seem to get my vacuum pipes in order after replacing my n75...2006 a4 2.0 tdi

It appears you've mentioned "Vacuum Diagrams 08 3ltr tdi 4x4 ranger," which seems to be related to a specific vehicle or engine system. However, your statement lacks context or t shirt manufacturer a specific question. If you have a question or need information about vacuum diagrams for a 2008 3.0-liter TDI 4x4 Ford Ranger or a similar topic, please provide more details, and I'll do my best to assist you.

check the pipe from the vacuum pump/inlet manifold to the brake servo for any leaks

COOLANT TEMPERATURE SENSOR THREADS INTO A COOLANT PIPE NEAR THE COOLANT OUTLET.LOOK AT SMALL COOLANT PIPES AT RADIATOR.YOU WILL SEE A SENSOR WITH WIRES CONNECTING TO IT.WITH COOLANT COOLANT HOSES CONNECTED TO IT.COOLANT TEMPERATURE SENSOR IS BETWEEN TWO COOLANT HOSES CANT MISS IT.YOU HAVE TO SQUEEZE CLAPS ON HOSES WITH PLIERS IN ORDER TO REMOVE HOSES FROM COOLANT SENSOR.

It sounds like you are getting very little vacuum assistance to your brake booster. I would check the main vacuum hose that runs to the brake booster from the inlet manifod as well as all those pesky little rubber vacuum hoses that are used for pollution control. They tend to go hard and split if they are over 8-10 years old, allowing air / vacuum leaks into the inlet manifold. One of these hoses probably also controls the operation of the turbo which inhibits its functioning .Check all hoses where they connect to the metal piping and replace as necessary. Any auto parts shop will stock the rubber hoses which can be bought by the foot.

check for vacuum pump operation - remove pipe at vac pump and check for sucking on end of finger, check pipework to brake servo unit for chafage / disconnection. if no vacuum at pump replace the pump ive had a few like this

If somebody replaced the turbocharger with a new one, you must check up all command vacuum lines, the entire air intake system (air pressure pipes, intercooler, connections, EGR - throttle vane, ...), and also turbocharger and EGR command solenoid valves (three pieces). Could be also MAF sensor defective! Here you have the vacuum air pipes connection picture for Audi A4 1.9 TDI (AJM engine):

how many miles has it done?is it remapped? we have had the same problem and done the same repair as above and the next stage for us is to remove the turbo and strip it down and clean the veins inside the turbo as these can stick and give a loss of power,this is on a 2002 gti tdi pd with +-130000miles and its remapped.my car is gt tdi 130bhp stock 140000miles no faults

i have problem vith car,my car is golf v 1.9 tdi motor code is BKC...number of code for problem is P0642 ("Sensor Reference Voltage "A" Circuit Low")
