Good afternoon all, I'm new to this forum and have recently purchased a 2005 2.0ltr HDI turbo however I am having cold start problems with the following codes from Mr AA man;

P1198 HDI PUMP
P1165 pressure problem.

I have been quoted £2000 for a main stealers to fix but I am quite handy with a spanner and will start tomorrow by changing the fuel filter and smashing a few tubs of RED-X though it hot, I have also bought a 2nd hand HDI pump and will look to replacing that this weekend.

My question is, is a pump change fairly straight forward? I have undertook a few engine conversions in various VW vans so I'm no beginner but re programming ECU's for new hardware is above me.. is that necessary?

Anyone done one before who could offer some advice or tips? I assume its front end off and go from there... plug and play... no timing as its HDI.. will i need to lock the cams off?

Many thanks in advance.

Gary

Its no bother. You'll have to remove the timing belt though. Is this car starting?
To be honest i wouldn't putting a pump into it without a proper diagnosis. Pressure problems can be down to alot of things.

Yes, it starts but with difficulty and only with some starter spray near the air intake.

So timin belt off/loose, timing mark on flywheel easy to see? Cams locked with a conventional bar I'm guessing?

I agree with above you need more than what the aa man says you should get a proper diagnostic reading of live data while cranking you should also do a leak of test on the injectors as a leaky injector will cause low cranking pressure pumps are actually pretty reliable as long as the diesel is clean

Many thanks. recommend a plug in at a dealers or specialists before I start spannering then? how much is that likely to cost?

It won't be the pump if its starting ie the pump is doing its job, creating fuel pressure to start the engine. No pressure no start. I'd be leaning towards the injectors and they're condition.
Around our way AA men are jacks of all trades masters of none. Theres no way in hell id go off what they say. They can't know everything.

Many thanks. Do you rate RED-X much? or think I should whip the injectors out and have them pressure tested etc?

Wouldn't touch any of that stuff. Waste of money in my opinion. All the redex in the world won't fix a leaking injector or hp pump.

No need to go to a dealer either there are people on here with the same equipment the dealers use will come and help you for a small fee and probably do a better job :)

Post your location on your profile we could be next door but will never know without all the info :)

There is a location map also with people who have planet

Agreed before atomisation, but if its a nozzle problem maybe?

Gonna do fuel filter and redex as thats already bought first then pop to a garage for a proper plug in. I'm just very "anti-dealership" for work other than plug ins etc...

Bit of an update,

Car does not start and I have pumped the manual errr pump till it was hard, there were air bubbles in the lines...

Does any of this point at a lift pump?

It has no lift pump in the tank. Its built onto the high pressue pump.

As said already fault codes don't really help with these and the air bubbles in your pipes are not really an issue all our taxis have air bubbles in the feed pipes and all run fine :)

You will need to get it on planet somehow to see if you have fuel pressure at cranking

It sounds like a siemens system they are a bit more troublesome but you still need to see what the ecu is seeing

Yeah plug up sounds like a must...

Gonna do filter and an Injector leak off test to try narrow it down a bit.
