Earlier today I experienced a fairly severe engine judder acceletating in 4th, followed by the engine light flashing momentarily. It has since gone out and not come back on.

I haven't been able to hook up the VCDS yet, but am expecting a low fuel rail pressure issue caused either by the HPFP or tank fuel pump.

Has anybody else experienced these symptoms and was there a known cause? Doesn't really feel like a misfire.

Was it around 3-4.5k?

Did the engine feel like it was coughing or 'popping'?

Yes about that rev range Harry and definitely a coughing rather than a popping.

Mine had a recurring judder which sounds very similar and it turned out to be carbon deposits on the intake valves. I seriously hope yours isn't that as it wasn't a cheap job to have resolved......

Faulty ignition coil?

I had this a few months ago. It was getting worse and more frequent but was due for a service so took it in and was going to get it looked at afterwards. However it came back from the dealer completely cured, felt like a new car. The only thing they did in the service that i think could have sorted it was to replace the sparkplugs.

Faulty ignition coil?

Could be. Certainly sounds like a misfire.

I had the coils replaced, then they suspected faulty injector but when going to replace that they found the real problem.

One garage had suspected the ECU which I was dreading. Looking back that'd have been cheaper :(

I've had issues with low fuel rail pressure in the past, the car is mapped and has an ITG Maxogen but it showed symptoms before I had a new map added.

I need to plug in the VCDS shortly but I've never had the engine light flash before.

Go cheap first, get your plugs out, if one is oily black its missing on that cylinder. Swap coils over, if its still missing, take plugs out, if same plug is still oily its the plugs if another is oily its the coil pack that you just swapped round.

Coil packs are £23 from ecp with discount. I know this because I had the same symptoms on mine last week and it was coil pack on cylinder 4.

Do I need to replace all four coils at the same time or can I just do one at a time?

Do I need to replace all four coils at the same time or can I just do one at a time?

Use vcds to find which cylinder is misfiring and swap coils from one of the other cylinders to see if the misfire moves.

I changed the faulty 1 and then another went 2 days later so ended up changing the lot. IMO Its worth while getting some new spark plugs as well if you can and doing those at the same time.

As said above, euro car parts sell what you need & use the forum discount at checkout (brisk25).

Someone suggested to me to check with your local skoda as some skodas had a recall on faulty ignition coils so maybe worth giving them a quick bell & seeing if yours is eligible.

So it turns out it was a misfire.

2 Faults Found:

000768 - Random/Multiple Cylinder Misfire Detected

P0300 - 001 - - Intermittent

000771 - Cylinder 3

P0303 - 001 - Misfire Detected - Intermittent

I haven't yet tried switching over the coils but will look at cylinder 3 coil and plug tomorrow. I have also not been able to replicate the misfire either, so no idea how or why it happened. Would an engine not in receipt of enough fuel misfire?

Just after I got the car I rang the local dealer and asked if the recall for the ECU update and the potential coil pack issue had been resolved - apparently there was no recall on my car for faulty coils and nothing more was done. I swapped out the original Bosch spark plugs at 60K miles and have had a set of NGK Iridium in for the last 10K - I assume these are going to need to be changed soon?

No coil pack recall? What age/engine?

2007 BWA

2007 BWA

Can't find the skoda notice but from an old Seat release:

"For the 2.0 TFSI the affected engine codes:

AXX-BGB-BHZ-BPG-BPJ-BUL-BWA-BWE-BWT-BYK-BYD"

My 2007 didn't need the coil recall either, I believe it must depend on which revision was fitted when it left the factory.
