TD4 HP pump Issue

Hi all,

Newbie here. Decided to join the ranks as have recently (for my sins) bought a second hand Freelander. Now before I get slated, despite being against the purchase originally I fell in love with the thing as soon as I started to drive it.

Unfortunately she is not as reliable as I would have hoped and I have been having troubles from day one.

Firstly the day after purchasing she refused to cold start. AA man got her started using easystart and the garage I bought it from fixed it and told me it was the cam sensor.

Three weeks later and after a few starting problems, once more she refused to start. AA man again could only start her using the crack cocaine of the motor trade. This time I took her to a specialist. The diagnostics read that the high pressure pump was to blame and quoted just over 600 quid to fix. I have a warranty up to £500 so not too much of a problem.

My question is though, firstly does this sound correct in their diagnosis? A little extra info is that before the breakdown she was showing signs of power loss between 70 and 80mph, just as the sticky thread says, inclines seem to bring the problem on but is intermittent. Would my current problem cause this issue or am I going to have to replace the boost solenoid as well?

Do not fear the garage I bought the car off is getting the full brunt off me. I believe as the car was able to be started with easystart their original diagnosis of a cam sensor was off the mark as surely an electrical fault could not be bypassed by easystart? Plus the cam sensor itself was far from a new part when I looked at it, sprayed with contact spray and wiggled it I believe they did.

Thanks in advance for any advice.

If it wont start from cold, but runs fine once started with easy start, then I would put my money on an leaking back injector not allowing the rail to pressurise, a fairly common fault.
The high pressure pump are normally very reliable. Just had a injector refurbished as same problem, this is the third injector I have done.
Once you get to around the 80k mark you tend to start getting the problem. Have found a good injector firm local that charge £68 + vat for a full refurb. I would ask your garage to do a leak back test.
As to your question about easy start, with being a desiel it uses the easy start as fuel so it would not matter it there was an electrial fault however once the easy start had been used up it would stop. The cam sensor normally only give a problem when the engine is hot, and once started it is redundant.

Thanks.

I am trusting the garage who ran a diagnostic and returned a fault code for the HP pump. Does anybody know this code so I can confirm with them before proceeding with any replacement.

Leak back test was carried out with no leakages. Apparently pressure pump was running at 1kPa as opposed to the 20kPa that is needed.

I am seriously considering the 'not fit for purpose' route for this one, still no reply from the company that sold me the car on what they intend to do. As the car has only been on the road for 3 of the 6 weeks I have owned it I would say I have a case.

Btw, the starting problem was both on cold start and hot start, it just happened to break down and decide not to move on a cold start.

Soon after getting my FL1 Td4 I was worried about the poor pull away from staitionary. Reading some of the posts here it looked to me like the MAF could be playing up but I took it to the stealers for a diagnostic check. They came back with a HP pump failure, took it back to the garage I got it from and they changed the pump. It took them 2 days because they did not have the sprocket holding tool so disturbed the timing chain.

After this it was only mildly better so I ran a few tanks with Millars in it which helped but finally fitted a Synergy 2 and MAF. What a difference

A poor HP pump would be OK at low-med revs but run out at higher speeds. When really knackered it would also drop of at really low revs as well, just the middle range working.

£600 seems a bit high, if you have the special tool the job is relatively straight forward if not its a real pain. Certainly in terms of garage man hour it is worth getting LRT-12-178

Cheers,

The original loss of power was around 70mph but as time progressed I was getting low rev loss of power too.

Still sitting here waiting to find out who is going to pay for it, it ain't gonna be me thats for sure...
