Been having some problems with my TDV6 HSE. When I give full acceleration, the car will go but eventually will stop accelerating. Almost like the accelerator does not function. If I push the car into neutral whil it is going, leave for a few seconds and then back into drive again, the car will continue going, provided I do not accelerate heavily. I can drive the whole day like this but it will only happen when I accelerate heavily. It also seems like it has a jerk or miss at certain revs and also like a "whoo-whoo-whoo" sound that can be heard when accelerating. This seems to be getting louder and I seldom drive the car.
After some testing, I sent it in for a fuel test and the Diesel Analysys Report failed stating that the Water Content Exceeds Specification. The car's fuel is contaminated which upon recollection, can be from a trip to Mozambique late last year when I had to fill up diesel there. I have been using 2SO in the vehicle to help prevent this from happening.
Anyway after some fights with our insurance company who will not pay, I will be fixing myself.
Sent the car in to get the tank flushed and a new fuel filter installed. They have done some tests after completion with the following results;
- P034100 - Camshaft position sensor A (bank 1) outside specified range
- P228800 - Rail pressure - pressure too high
- P193400 - Driving speed signal - signal improbable
- P120E00 - Unknown fault
They have also mentioned that the test of the injectors are not up to spec and they would need to be replaced - about R35000. The injector correction values for injectors 1-6 respectively are: 1047.52, 926.99, 1160.25, 962.95, 946.51, and 950.50.
After getting advice from some members on the forum, I was told to purchase 3 litres of Liqui Molly Diesel Purge along with 500ml 2SO. Add to the tank when the reserve light comes on and take for a good belt, keeping the revs up at all times. This still did not help.
I do not just want to replace the injectors as this is a very expensive option and would leave as a last resort. I do not notice the car smoking but this is from the drivers seat and I have not driven behind the car. I have also heard that injectors do not just pack up and that they can be cleaned ultrasonically or something like that. Is this the case?
What would you see as the way forward with this?
I am in Pietermaritzburg and would need to take to someone that can fix. Who would you recommend?
