Ibiza FR - Mild Shudder

Post by CoalWorld23 »

sup gents,

i've recently noticed a mild shudder on my Ibiza FR (96kw BLT motor).

Car drives like normal most of the time. VCDS shows no faults.
However, when the car is stationary and idling, the car has a mild shudder every few seconds like it has a miss.
also, under extremely light acceleration while at speed or take my foot slowly off the accelerator, the same miss can be felt.

Any idea as to what it could be? :bang:

Hows the fuel filter?

Check injector values, engine - group 13

When a car tailgates me, i slow down - then floor it and give them a cloud of diesel smoke to choke on :driving:

Car was just serviced by VW not even 4000km ago.
Injector values all within safe range.
fuel filter looks okay too.

How do i check the MAP sensor?
VCDS picks up no faults

Did vw even change the fuel filter? Days of trusting dealers are long gone.

If the map sensor is faulty the intake temps will be all over the place or the car will either over or under boost maybe even no boost at all. U can do a log of this and see what happens when the misfire happens

And, what are ur values?

Update:

Took the car to 86auto/ACD for an oil change.
Turns out my initial hunch on the gearbox mount was correct.
one of the nuts on it was slightly loose. all the guy did was tighten it and sorted :hurray:

all values on injectors etc well within range
