So the problems continue.

2006 2.0 HDI 307 SW 136BHP
Been having problems where the cars keeps faltering quite badly and you cant get the revs back up.

Had some wonderful advice from you guys already but still have the problem.

Code P1198 Fuel Pressure Regulator Faulty.

Got a "mates rates" diag' from main dealer and they are not convinced that it is the regulator and wanted extortionate sums to investigate further.

Apparently rare for one to fail, so they suggested wring fault at ECU or blockage in gauze by sender.

Failed to manage to get the sender out and ECU problems scare me,.

However have noticed a fuel dampness around one of the injectors, could this cause this code???

Is there anything else I should / could be looking for before having to fork out tons of money replacing parts.

Your help is really appreciated.

Thanks David for getting back to me.

That was the 1st thing I changed, Bugger to get off but new one fitted, old filter was clean and bowl had no debris.

Its already had a main dealer diagnosis which simply revealed the P1198 code. Unfortunately they then wanted stupid money to investigate further. Apparently live data was showing low fuel rail pressure but they suspected either ecu wiring or gauze in tank. As I say I also see I have a leaking injector and I was wondering if this would also produce this fault.

Really need to get this sorted and money is far too tight at the moment to start throwing parts at it or paying garage rates.

All your replies are very valued and I truly appreciate them.

Thanks

I obviously wanted to check the sender but could not get it out, my question was in the 1st post about my leaking injector and if that could be the cause of the error code. I was also looking for any other suggestions that I could check my self.

My thanks to you gibbo, it looks like you help a lot of other people on this forum.

David, Thanks as always for your advice, how would you test a high pressure fuel pump and be sure it id the pump and not wiring, pressure regulator or ECU.

I am sure this is a stupid question but I need to be sure in my own mind before spending out anything else on this car. I really have bought one with lots of problems and the more I find the more I wish I bought another brand.


Thanks as always.

Well to be honest you have spent money at places that seem to haven't a clue about the workings of a common rail engines fuel system.
The checking of the high pressure pump is dealer or good diesel specialist using special equipment.
A good dealer will have all necessary expertise and equipment to check this.
Id love to say bring it into me but slight problem with distance. I have all the high pressure pump testing gear.

As has already been said you have had a couple of pointers the filter on the intank pump assuming bosch system can get clogged I have seen it a few times probably not your problem but worth eliminating try harder to get it out :)

Your leaking injector may be an issue depends what you mean by leaking as leaking injectors will cause low pressure in the rail BUT the leaks are internal you cannot see them.

An external leak could be spill pipe or injector seal neither of these should affect fuel pressure much although if its the spill pipe it may affect it a little.

Live data gives you a look at what is going on codes are not as usefull.

Thanks for you help. I have been forced to put the car into the garage (Bosch diesel specialist), will post the outcome as I too would like to help some other poor bugger who has purchased a dud!
