Misfire - Leon Cupra TDI

[47poles]

I recently purchased a diagnostic reader for my Leon Cupra TDI. I have fault reading that says 'misfire'. Could this be a dodgy connection or more? Any help please!

Whats the code?

It just came up as misfire.

I will plug in again, but i deleted the misfire reading to see if it comes back again!

What kind of code reader is that?

 

[47poles]

It's a U480 universal code reader.

 

[adam cupra 20vt]

Well hopefully it will bring up a proper code and we will be able to help you out

Edit..

Thats the code reader I have and it only displays codes?

Sounds like a paper-weight to me, a misfire on a tdi is both rare and very noticable if it was present.

Hmmmmm, I will plug it in again later. It says to plug in before turning the ignition on, then turn on the ignition so that it will read. Hope i haven't got a dodgey reader!

The engine management light has not come back on again yet! It feels like it's running a bit rough. Had it serviced 1500 miles ago!

Any ideas?

who serviced it? Plug the reader back in and see what it says.

How much was it and where did you get it from?

I bought the reader fron Lonelec last week, it picks up faults but as I erazed it !! no doubt the light will come back on soon! I will plug it in again in a mo and see if it picks anything up.

Yep, as I thought.... plugged it in and no DTC's. Scrolled through the I/M and the only thing that came up was CCM - 'not ready'? was does this mean?

Any thoughts would be appreciated.

Well, the engine management light is back on, so I plugged in my U480 MEMOSCAN. It has picked up a fault but it won't tell me what it is!!!!!

It reads: / 1.DTC / FAULT: 01 PEND: 00 / N/A 01/01

Reading the manaul, N/A means - The monitor is not supported on that vehicle...... What!!!!??? I e-mailed the seller to specifically ask if it would work!

Is it me, the scanner or the guy i bought it from...

Really frustrated now!!

Also under 3. I/M / MISFIRE N/A / FUEL READY / CCM READY / CAT N/A / HCM N/A / EVAP N/A / 2AIR N/A A/C N/A / 02S N/A / HO2S N/A / EGR READY.

What does all this mean?

Help please...i bought the scanner to save time and money, but just getting stressed now!!!

Thanks
