Ignition coil MSD or OEM Volkswagen

Sounds like coils to me. I wouldn't even mess with swapping them...I would just replace all four. You can do just 2 and 4 but then you can expect 1 and/or 3 to go soon.

I have an MSD blaster 2 coil on my 93 fox and it works great. I went with this coil for convenience (bought at a FLAPS when my stock coil died) rather than performance, so unsure if there are any gains to be had (doubtful).

I read up some online and decided to order new ignition coils. Took a few days, but I got four new coils and threw them in. Again, problem solved it seemed. No more EPC light, misfire codes didn't come back and no more rough starts.

I was having hesitation problems a few months ago while accelerating. No CEL, and no codes with VAG-COM. I read here that a lot of other people had had identical problems; the CEL and codes didn't start appearing until well after the symptoms started. Changing the coils solved their problems. So I took the risk and changed all four coils (at about 65,000 miles). That completely solved the problem for me. By the way, the new OEM coils had a completely different part number than the original ones.

after you check the dwell and all wiring looks good, it may help to switch to a different coil like the MSD Blaster 3.

I've had similar spark plugs fouling up issue with the G60 turbo swap in my caddy. After checking all the stuff you mentioned, I upgraded to an MSD Blaster 2 coil and NGK plugs with a wider gap (0.030). So far so good, running on all four cylinders now.

I ran a Blaster 2 on my old car for a bit. Idle was a little smoother, but it was probably because the coil on it was crap. No real performance gains expected.

Ok, So today I cleaned all the grounds then checked them with a multimeter, put new plugs in, changed the ignition coil, and still won't start. It has good spark now, and it's definitely getting fuel.

VW makes bad ignition coils, period. Bad design, bad reliability, bad everything. They actually came out in pieces and were siezed into the head on some cylinders. There was several inches of calcification and junk from water going down into the holes (no engine cover for 123,000 miles). I had to blow out the plug holes with air compressor, after I vacuumed the inches of calcium dust out, then still after I removed the plugs found rust under the crush washer they seat on. It wasn't fun and I had to polish the holes up to hopefully stop that disgusting build up. It was BAAAAAD looking but it ran fine with only a single misfire up to almost 130k.

Turned out to be bad coil (again).
