2006 KJ Cherokee 2.8lt turbo diesel manual. When I accelerate engine surges then flat spot then surges again as it accelerates there is also a lot of black smoke coming out of the exhaust pipe


There is a waste gate on a turbo and that gate dumps the excess pressure in the manifold. There is a sensor that determines when the gate opens and closes. You need to run a diagnostic scan and see what the waste gate and sensors are doing.

Thanks Terry. The car does not have full power.


Are you getting turbo boost pressure, waste gate may be open check waste gate actuator. Check that BOV is not stuck open you could clean with some throttle body cleaner. http://www.youtube.com/watch?v=govRsNtY8DM

Gate ajar lite stays on dome lite wont shut off


I would start off with some WD 40 on the gate button and check the wires for corsion or bare wires touching, with the gate open the dome light comes on. Worst comes to worst get a new or used button at a junk yard.

2001 vovlo v7o xc trouble codes p0014 and p1237


DTC P1014 - B Camshaft Position - Timing Over-Advanced or System Performance (Bank 1).
At engine start-up the control module checks that the camshaft is in the correct position in relation to the crankshaft. Diagnostic trouble code (DTC) ECM-62 is stored if the control module detects the camshaft in an incorrect position on start up.

Possible source:
Camshaft cogs incorrectly seated
Incorrectly installed camshaft pulley
Contact resistance in the terminals.

Condition:
Malfunction indicator lamp (MIL) lit
The engine misfires.



DTC P1237 - Turbo Control Valve
Looks like the turbo is not producing enough boost. Check the waste gate hoses and the waste gate itself to see if its bound up. If the waste gate is working right, I would suspect a bad turbo.

This is an advanced level repair. You may want to have Volvo do the diagnostics on this one. Your code is for low turbo boost pressure. The waste gate is a big silver actuator on the turbo. It has vacuum hoses going to it. See if they are all hooked up. Also see if you can move the lever that the actuator pushes on. If its jammed that may be your problem.


Hope this helps and just keep in mind that your feedback is important and I'll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa.

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.

Lack of power using way more fuel and hissing by the firewall , i unpluged hose off wste gate box , pretty well same thing happening, maybe bit les power


One of your turbo boots or intake boots is off or has a hole in it! Could be either cracked or has come loose of the clamp. This is your hissing noise your hearing. It means the turbo is making the boost but it is not getting to your engine. Its leaking out the boot. No boost no power! Poor performance and bad fuel economy too. You need to check all of your boots and clamps. If you say it is by the firewall then start on the side that the hiss seems to be comming from. DONT unplug your turbo waste gate as you can damage your turbo or other engine components! your waste gate allows excess pressure not needed on your exhaust side to escape.

My 2004 passat TDI is giving me an exhaust leak sound noise.


This vehicle certainly does have a waste gate and they do have problems. However the waste gate diverts exhaust internally so you would not hear any unusual noise if it was being problematical. Also if the expected boost from the turbo did not match the actual boost there would be a check engine code and light on. If the hoses between the Turbo & the intake have a leak there may be a similar loss in power depending on the extent of the leak. It would be best to scan the engine computer to see if there are any Codes.
