The Dreaded Engine Management Light...

[BeefMasta]

Not too certain but somewhere in the vicinity of £300?

Jamie quoted me around that when I asked.

I know you don't want it to be this, but it seriously could be the timing chain. If not improving get it looked (same symptoms and in the end only changing this sorted it and it was really stretched)

[WTF]

Sorry to hear it wasn't a straight forward easy fix

[RedKez]

Can anyone help, changed spark plugs and coil packs now, both times it fixed the problem for a couple of weeks each before the light comes back on again, pressures are all okay apparently so he doesn't think it's the fuel pump but think it's the injector on cylinder one?

Can anyone shed some light on this? It's going to be another few hundred pounds and he's not 100% sure it'll fix it!

[RedKez]

The codes are
P1336
P1338
P1339
P1340

[Jamie@SPTuning]

You have misfire across all 4 cylinders with those faults so fitting an injector in cylinder 1 will not fix it....
Fuel pump would be my first assumption.

[RedKez]

Cheers for the reply Jamie, I did say to him can you check the fuel pump/pressure and he said that's all fine.
Really stressing me out I've been to 3 different garages for opinions and no one seems to know what to do!

They are hard engines to work on if you don't really know them. All my knowledge came from trail and error and this forum. But difficult to diagnose if we can't touch the car.
As Jamie said, could be the high pressure fuel pump. And because the error codes are pilling up and it now beeing not one cilinder anymore it probably a more general problem (eg hpfp).

I've got similar issues with my 62 REG 1.6vti 120. Judder/lack of power around 1,500 revs, especially from cold. Engine fault light coming on after particularly bad judders before disappearing a few days later. Currently in dealership for the 2nd time after not been fixed first time.

I've not seen reference to this problem on the 1.6vti so wondered where I could point the dealership towards looking? They've mentioned swapping coil packs so far but not replacing them. Reckon they had improvement after swapping. I'm at a loss as the car is fine if I stay higher than 2,000 revs but it's a problem I want sorting before warranty runs out. Any ideas?

It won't be anything to do with what causes the THP problems as the engine works completely differently.

Could be injectors blocked, could be coil pack as mentioned, could also be temperature sensor if it happens more when cold. How does the needle behave? Mine died and thought the engine was half warmed when it was about 7 degrees outside and really struggled to start as the ECU thought less fuel was needed than was the case. When it finally did start, it was VERY rough, revs jumping and stuttering, then cutting out unless I kept it over 3000 RPM until it had actually warmed up to the point it thought it was.
