Hi all,
2 questions; one just a simple question, the other maybe not so simple.
1) Has my 2008 hst td4 auto diesel got a timing belt or chain ?
2) engine stops on occasion and I get a dashboard message 'something like' reduced engine power ? this message appears very briefly, hence it has taken some time to read. I only get 24.4 mpg, somethings not right, and I just changed the 'transfer box'

Any help would be hugely appreciated
Many thanks
Marcus

1. Both! A chain connecting camshafts and a belt connecting crankshaft to camshafts.
2. Have you had the codes read? Normally you’d get the engine management light come on but, as you get a message the fault code should be stored in the ecu.

I had the occasional engine stops in traffic which then developed to random jerkiness at speed which then developed to engine cutting out during an overtake and also that same message. Read the codes and it was the crankshaft position sensor. Changed that and all good since. However, with that poor fuel consumption it sounds as though your's might be something else. FL2 HSE Auto Galway Green

Many thanks to you both,
Now a question regarding those belts, it's a 2008 diesel with 106k on the clock : Should they both be changed ?

Pedro: I'll get my mechanic to look at the the crankshaft position sensor.

I'd do it myself but unfortunately I'm not very well, I have maybe 2 years left, so I can't do much. Shame I only bought the car as treat for myself last December and I've already spent a small fortune on it. I got it from a car auction, so NO kind of guarantee.

You’ve also got 2 fuel pumps. One in the fuel tank pumping fuel over the drive shaft tunnel and a high pressure pump driven by a cam shaft that sucks fuel from the tank to supply to the fuel rail. The fuel filter needs changing at each service and the system needs to be properly bled. A blocked filter can stop the engine, which will miraculously restart a few minutes or hours later. The camshaft to fuel pump linkage is the weak point on earlier cars with the end of the camshaft fracturing and bits falling into the engine.
The chain isn’t a service item. The cam belt is. Recently reduced to 7 years on some my’s. Do the water pump and tensioner and pulleys at the same time.
As for fuel consumption, it’s an auto so tends to use more than a manual and both depend heavily on usage. Around town, abysmal, long distance not really that bad. My average in a td4 gs manual is over 33mpg for the last 10 years.

Thanks to BossBob for the reply,
Mine has restarted straight away after cutting out, so maybe its just the filter .... fingers crossed that does the trick because money is tight now, is there just the one fuel filter ?
Many thanks for all you help, if anyone else wants to throw their hat in the ring please do.

Make sure it's a genuine fuel filter, many have had problems with cheaper copies.

Thanks Dave,
I'm hoping my mechanic is putting a right one on, it should be fitted Wednesday. Shame I'm not well, looking at the 'web' it looks like an easy fit that I would usually do.
Thank you very much for your advice
Marcus

Yes just one filter, located in the engine compartment under the black engine cover. It needs to be properly primed with fuel. There are guides on the forum. Some make sure they plug all the lines as they remove the old filter, fill the new filter with fuel and fit it, others plug lines, fit the filter then use a vacuum pump to draw fuel from the tank through the filter. Either way, the idea is to get rid of air in the line to the high pressure pump to the fuel rail.

Sorry for such a late thank you BossBob,
I am quite unwell and have very sore eyes from looking closely at the screen, therefore I turn my PC off around 5pm so I've only just seen your message.
I'll make sure that the mechanic does the job right, he always has in the past, but I'll just remind him.
Thanks for all your help
Marcus

My thanks go to Pedro, Dave and BossBob for the information they have provided. I looked on the internet and have sent the fitting guide (video) to my mechanic and reminded him to only use the genuine replacement part.
Many thanks
Marcus
