SOURCE: the system detected a leak

Replace the gas cap and clear the fault code, most times this clears the issue with code P0455. If it does'nt then you will have to have test equipment hooked up by the dealer to find the leak.

SOURCE: no acceleration,audi 1.8t,runs like no boost

It's possible that the diverter valve (DV) has failed. The OEM valve has a plastic diaphragm inside and it can crack. If this happens, the car will leak boost air and will lose power as a result. Go to www.audiworld.com, click on Resources, then Tech, and then go to the engine article about replacing/upgrading the diverter valve - it'll show you where it is and how to do it.

SOURCE: Audi A4 need to replace rear brake light on audi a4

Inside the boot is a plastic cap embeded in the boot liner. Remove the cap to reveal a screw. Undo the screw and the whole rear light cluster will come away in a sideways and not rearward direction to reveal all of the bulbs. Hope this helps.

How to fix 17887/P1479 brake boost vacuum and 18033/P1625 powertrain data bus?


I would go to the data bus first. No easy fix for this. You need a scanner( not a code reader) to trace this down. You also need wiring schematics and pin outs for the plugs. And a volt/ohm meter. after that issue is fixed. If you still have the booster problem, replace the vacuum pump.

1st & 2nd gear, then complete loss of power. audi a4 tdi 2007


I presume you experienced a loss of full power but had enough to get home. The check engine lamp came on too?

It seems your engine is in limp mode due to a possible over boost pressure . The ECU runs the engine with reduced power after an over boost is detected. If you cycle the ignition key and power comes back, this is most likely problem.

A fauliy N75 solenoid, with three small bore vacuum hoses and an electrical plug/connector, is possible cause .

This over boost can be caused by sticking vanes inside the turbo .

Have it scanned and read the codes. Code P0234 will be set if over boost occurred.

Here try this solution...You posted P1479. ...When this fault is stored in conjunction with misfire and system lean fault codes check the PCV system and any other possible sources of engine mechanical vacuum leaks. Although PCV failure is most common on the 1.8T engines equipped with the auxiliary vacuum pump, any engine with low vacuum can cause that electric pump to run excessively - resulting in this fault code. Good luck.

Yes If you have a vacuum leak it will pop the oxygen sensor codes to rich/ to lean. the rpm code is some thing different, it could be as simple as you over revving the car.
