Hi

My 2000 2lt gti has developed a 2 cylinder misfire.

Had the car recovered to a garage who replaced the cam sensor, then the coil pack and plugs, did a compression test an checked voltage to injectors, and finally 2 injectors.

Car is running the same.

I have now been told its more than likely a BSI problem.

I don't mind replacing the bsi, if I can prove without doubt its that. I appreciate it can be pricey, but what is involved?

Any suggestions?

Thanks

Dave

Which two cylinders ??

Another garage would seem a good idea.

As for the BSI being the fault, no way !!

Hi Kev

I think, and its only think, 2 and 3 cylinders, I have found out this morning that they changed the Crank sensor not the cam sensor.

Surely for a misfire, it would need to be the cam sensor as that would know which cylinders require fuel as it has 4 positions, where the crank has two, or is that too simplistic.

Head Gasket failing between Cyls 2 and 3 ?

Cylinder leakage test would confirm

It beggers belief, what sort of garage can not diagnose a 2 cylinder misfire, Crying

Um, that is too simplistic I'm afraid and anyway failed crank or cam sensors are not a usual cause of permanent misfires. But really I agree with SB126, your garage shouldn't be replacing parts and spending your money on what looks like a sort of "let's try this" basis!Basically for a cylinder to fire you need three things. Fuel/air mixture in correct quantities, a good spark at the correct time and compression when needed. I'm not convinced from what you've said that any of those things have been properly checked.
Oh and Kev is right as well. Whatever the cause this is NOT a BSI issue!

Hi

Problem diagnosed by my usual garage, as cam sensor and coil pack!



Seems previous place screwed everything up by disconnecting injectors while the car was running.



Also they lost most of the engine cover clips and the washer bottle cap!! And many electrical covers are pulled back.



Someone caused a secondary problem, as the breather hose on the engine was split, causing low rev hesitation.



Back up and running with repaired hose, just got to saurce a new one.



Any ideas of a good outlet anyone?

"Any ideas of a good outlet anyone?" Yes genuine if it,s still stocked.

Repaired hose, seems to have made a big difference, but still not 100%,

So it's had another new coil pack and cam sensor? I don't see how disconnecting injectors would have damaged them, it sounds more like the previous garage never did change them even though they told you they did. Don't go there again!
