Update.

Unplugged MAF - No difference.
Replaced HPFP Regulator seals - No difference.



Also replaced the bonnet struts after the bonnet fell on my head.

Waiting for the interface cable to turn up now to see if I can read anything from the car.

Do a leak back test sounds like an injector problem.

Hi Artic,

Did that already - using that very same kit from eBay (first post)

Quote:
I did an injector leakoff test. After 2 mins of cold running, I had the following:
Cylinder 1 - 12ml
Cylinder 2 - 13ml
Cylinder 3 - 8ml
Cylinder 4 - 13ml
(this included draining what was in the tubes into the catch bottles)

From what I have read, anything under 20ml for 2mins of running is good? Bit concerned why cylinder 3 is a lot lower than the others?

OK, have managed to get a cable soldered up and got TOAF connected to the car. Can't seem to see a way to read live data, but did get more error information.

Injector Cylinder 2
Sporadic Error
Error 1
Injection volume: 25.60 mm^3
Rail Pressure: 319.28 bar
Error 2
Injection volume: 24.58 mm^3
Rail Pressure: 319.28 bar
Error 3
Injection volume: 24.58 mm^3
Rail Pressure: 319.28 bar

Injector Cylinder 3
Sporadic Error
Error 1
Injection volume: 25.09 mm^3
Rail Pressure: 331.33 bar
Error 2
Injection volume: 25.60 mm^3
Rail Pressure: 325.30 bar
Error 3
Injection volume: 47.62 mm^3
Rail Pressure: 295.18 bar

Injector Cylinder 1
Sporadic Error
Error 1
Injection volume: 33.79 mm^3
Rail Pressure: 319.28 bar
Error 2
Injection volume: 25.09 mm^3
Rail Pressure: 289.16 bar
Error 3
Injection volume: 25.09 mm^3
Rail Pressure: 289.16 bar


Nothing showing for Cylinder 4 - however all four cylinders picked up an "Injector Circuit A" fault on my ICarSoft - albeit with no further information.
I suspect that the errors on Cylinder 4 just had not come back.

Anyone have any thoughts?

Have you cleared the codes and tried running the car, switching off and doing the test again?

Hi, Yes, the above errors are the results of doing so.

Got distracted by taking off the bumper to replace the fan resistor, and ended up polishing the headlights :-)

Anyway - after chatting with Russ (thanks Russ), have ordered a set of injectors to see if that fixes the problem. Hopefully should be here by the weekend.

So......

After a few failed attempts to get injectors, I finally got hold of some and fitted them, together with nice no "O" rings and copper washers, and some nice new gaskets/seals on the inlet manifold.......

and......

Still the bloomin' same! Stupid car.

It does seem * slightly * better - it still takes too long to start, but when idling, does not cut out. I also took it for a drive, and it didn't cut out when driving.
It does however seem quite rough for the first 30 seconds or so after starting (although it was rather cold today so I can forgive it for that).

So - any other ideas?

(I also seem to have broken my dash somehow as well - separate thread on that).

I had a similar problem when my fuel check valve(non return valve) broke. It's so small with the Pierburg sign. It is located under the battery.

Have you checked the wiring to the injectors? Get someone to try and start the engine while you wiggle the wiring to the injectors.
