Oh woe is me :(

Right then, following on from my previous thread I am still having problems with my 75 diesel. The problem is still the same, it starts fine, but cuts out as soon as it approaches 1500rpm. I have done the following...

Fitted a new ECU
Changed the MAF sensor
Changed the filters
Cleaned the EGR valve
Changed both the fuel pumps


The question is has anyone any idea of where to go next with it? Could the camshaft sensor be faulty? Is there a TDC sensor? If so could this be a fault? This car is rapidly making me go bald lol

Injectors, have you tested them for leakback. If they are faulty then the engine will cut out under accelaration just had mine serviced.

Ye gods!

I do hope you got your money back after changing the ECU and pumps if it had nothing to do with the fault.

As for maf simply unplugging it is all you needed to do to eliminate it from the equation

you say it cuts out at 1500 is that when under load or simply when reving the engine?

I assume if the ecu was changed they did also monitor the car via Testbook to see what was happening at cut out?

It cuts out when you try to rev it. Cant really move it as as soon as you get to a bit of a slope if you havent got enough ommph it cuts out. The ECU was replaced as it suffered swimming pool syndrome

Could there still be a problem with the ECU causing the cutting out?

I would love to see what the low and hi fuel pressure readings are on my T4 as it happens I suspect it may be fuel delivery related

One of my friends had an identical problem on his CDTi and it was a faulty air flow meter giving incorrect readings and just starving the engine of fuel.

I hope that you can get it sorted out..... Good Luck!
