First of all, YOU MUST HAVE ALL FUEL LEAKS REPAIRED BEFORE TRYING TO START MOTOR.!!!!

If you by any chance get the car running with all those leaks, you will be exposed to have a very serious accident.

After your leaks are repaired, we'll be happy to help you to start up your vehicle.

Good Luck,

95 Courier with Mazda diesel is hard to start, runs rough, blows lots of blue smoke and won't go over 60kph in top gear


I'd get your injectors rebuilt, and tune up your injector pump. Run a little seafoam in the diesel tank, and in the oil. Should make it clear right up.

Hi, noticed a post of yours rear cambelt replacement on an a4 1.9 tdi ajm year 2000. Would be very grateful for any instructions. The car is stripped down ready for cambelt removing. Stuck on lining up...


Hi, I have pasted instructions below from autozone.com. The instructions call for the use of special tools. You can improvise with alternate tools, but please make sure your timing is right before closing the cover. Please let me know if you have questions, and thanks for using FixYa.

1.9L Diesel Engine
Some special tools are required to perform this procedure properly. A flat bar, VW tool 2065A is used to secure the camshaft in position. A pin, VW tool 2064 is used to fix the pump position while the timing belt is removed. The camshaft and pump work against spring pressure and will move out of position when the timing belt is removed. It is not difficult to find substitutes but do not remove the timing belt without these tools.

WARNING Do not turn the engine or camshaft with the timing belt removed. The pistons will contact the valves and cause internal engine damage.
  1. Disconnect the negative battery cable and remove the accessory drive belts, crankshaft pulley and the timing belt cover(s). Remove the camshaft cover and rubber plug at the back end of the camshaft.
  2. Temporarily reinstall the crankshaft pulley bolt and turn the crankshaft to Top Dead Center (TDC) of No. 1 piston. The mark on the camshaft sprocket should be aligned with the mark on the inner timing belt cover or the edge of the cylinder head.
  3. With the engine at TDC, insert the bar into the slot at the back of the camshaft. The bar rests on the cylinder head to will hold the camshaft in position.
  4. Insert the pin into the injection pump drive sprocket to hold the pump in position.
  5. Loosen the locknut on the tensioner pulley and turn the tensioner counterclockwise to relieve the tension on the timing belt. Slide the timing belt from the sprockets.

To install:
  1. Install the new timing belt and adjust the tension so the belt can be twisted 45 degrees at the halfway point between the camshaft and pump sprockets. Tighten the tensioner nut to 33 ft. lbs. (45 Nm).
  2. Remove the holding tools.
  3. Turn the engine 2 full revolutions to return to TDC for the No. 1 cylinder. Recheck belt tension and timing mark alignment, readjust as required.
  4. Install the belt cover and accessory drive belts.
    NOTE If the belt is too tight, there will be a growling noise that rises and falls with engine speed.

YOU HAVE TO RETIME BY REMOVE AIR CLEANER.REMOVE CYLINDER HEAD COVER.AND TIMING BELT COVER.TURN THE ENGINE TO TDC OF THE NUMBER 1 CYLINDER HEAD.YOU NEED TO INSERT A SETTING BAR INTO THE SLOT ON THE REAR OF THE CAMSHAFT.VW TOOL 2065A OR EQUIVALENT TO HOLD CAMSHAFT IN PLACE.WHEN YOU RETIME THE INJECTION PUMP YOU HAVE A PIN ALIGNMENT SLOT ON THE SPROCKET HUB IT SHOULD BE AT 12 OCLOCK POSITION.YOU HAVE TO INSERT LOCK PIN TO HOLD SPROCKET IN PLACE.WHEN YOU INSTALL THE TIMING BELT.YOU HAVE TO PRIME THE INJECTION PUMP.BY HOOKING A HAND HELD VACUUM PUMP TO THE RETURN LINE FITTING AND DRAW FUEL INTO THE INJECTION PUMP TO KEEP FROM DAMAGING PUMP IF PUMP IS DRY.THIS WILL GET VAN GOING BUT THE DEALERSHIP STILL HAS TO RETIME TO INJECTION PUMP USING A SCANNER.IF VAN DONT CRANK BROKEN BELT COULD HAVE DAMAGED THE VALVES AND PISTON.

A6 2.5 tdi possible injector pump failure or timing slip


I had the same sort of problem withmy A^ 2.5 TDI sports, after the dealer spending approx 1200 quid the problem was still there .
Does the waring light on the dash [glow plug symbol] show under hard acceleration?
After all the so called UK Bosch and Audi -VW experts diagnostics failed to find the fault including changing the sensor injector on NO2 cyl the problem was located by myself after giving up on so called experts { X being un known, spert being drip under pressure] all of the symptoms dissapeared when the fuel tank screen was removed and cleanned, the screen had a 2mm covering that looked like a rubber flap. Some 30,000 miles on all is perfect.
