Throttle valve looks like it opens and closes ok. (Also did a VCDS test of that before doing a test of the EGR valve while it was out.) Also tried a different ECU.

Thanks. They seem to be, from opening the upper cover (second video link).

Replaced that coil pack, didn’t make a difference.

Hi, Driving home the engine died on me, from about 30mph and 2500 rpm it gradually died, no juddering, no ominous sounds. I got it pushed back home. Now it won’t restart. Have looked at the following - VCDS, no codes thrown - Fuel gauge says 3/4 full but added some anyway. - EGR valve removed and sprayed with cleaner and refitted. - Fuel rail valve spits a tiny amount of fuel out when you press it. - Spark plugs look to be getting fuel to them - We disconnected one fuel injector and got a code, as expected - Don’t think it’s a coil pack as I had one of those go before and the car ran rough and would start albeit roughly. Now it won’t start at all. - Pulled one spark plug out, reconnected coil pack, and earthed it, tried starting. No spark seen. Ideas welcome. and

Hi. fwiw it probably won't change your suggested diagnosis (the car is going to a garage next week for MOT and for this to be investigated), but I did a little test drive. - excessive vibration in all gears whilst accelerating up through about 2000-2800 rpm, then it smoothes out (harder to detect in 1st as I pass through that range quickly) - excessive vibration in all gears whilst decelerating (easing off or foot off the gas, but in gear) down through the same range - no significant vibration at constant throttle within that range - no significant vibration when dipping the clutch in any gear from about 2800-3000rpm and the revs fall quickly to idle Cheers, Jon

Gotcha.

Curious - if it was the friction plate, wouldn't it vibrate when in neutral and stationary?

Great, I really appreciate your insight and explanation. Will investigate a new clutch.

It's changing gear fine. Would you expect that if the plate is broken? When you say 'zombie clutch'...?

I couldn't tell you about any change of clutch. Not in my ownership. It's a rally and autosolo car that gets some abuse - lots of 1st and 2nd gear racing - so a clutch issue would not be too much of a surprise. Just did a test when stationary. It's smooth when increasing the revs for idle up through to 3000rpm. On the road, it will cruise without any vibration as soon as you reach just under 3000, and acceleration over 3000 to the redline is smooth as well. It's just driving and accelerating through around 2000 (maybe just under) up to nearly 3000 that the car vibrates.

Hi, yes, it doesn't matter what gear I'm in.

Hi, My Fabia 1.4 petrol has always had a vibration to it since I've had it (about a year) as you accelerate through about 2000-2800 rpm (above that it's fine), which vibrates the whole car. Feels like it's got a bit worse recently and also I think there's a rattling sound audible as you slow down to a stop. All feels like it's emanating from the front left. Engine mount? Knackered suspension part? Someone has asked whether I have a dual mass flywheel - do I? Thanks, Jon
