Need To Get A Smoother Engine Help Please

[zorgman]

hi all.

right then my 1.9tdi 110hp is still not right to the point i now hate driving it but cant afford a change of motor.

have done the world to the engine but its still very high on noise levels and just isnt smooth, not able to check against another tdi i can only assume its got a fault, it sounds just like a tranny van and im not happy with that.

ive rebuilt the whole top end with new parts, timing i spot on with vw tools then vag-com, all mounts are spot on, pistons have been checked inc bearings.

so any one a suggestion to quiet the bugger down

 

many thanks

laurie

Have you read the thread "alternator Workshop" Error. Noisy At Idle? on page 3 all about the alternator pulley & belt tensioner?

And things on the Dual Mass Flywheel?

deffo not alt or flywheel, this noise ill describe as the combustion noise more the mechanical rattle etc only there when using throttle, i do know tdi's are noisey but mines in the extremes.

gonna give another go at it if not is going journey, shame realy as its a fully loaded sharan

It is obviously difficult to get a clear idea of just how noisy yours is and you do not mention anything about power level but I am having problems with mine at the moment which, while variable, do seem to be similar to what you are describing.

 

In my case, the problem seems to be definitely linked to the 'start of injection timing' which seems to be varying between 0 and 20 deg advanced. At 20 deg error the thing sounds like an old taxi and runs rough and weak. It's latest condition is a stable 7 deg error which does not produce an error but it is more noisy and less lively than it should be.

 

You say that the timing is OK and I am offering this just in case you have not looked too closely at this issue and because of the similarity of the symptoms.

hello if you want rid im looking for another one just use for works vehicle . give it a thought thank you

hmm ill check more into the timing but its rock solid just above the ctr line in vag com. Cars got masses of power due to 216 injectors i fitted hoping that would fix it but was exact same tho give it a healthy boost in power.

im giving it major thought on selling it but its not a rust bucket and i would classify it from mint upwards
